Description

   Method for painting partition plate and its plate {Method for painting of partition plate and the partition plate}

The present invention relates to a partition plate coating method and a partition plate manufactured by the method used in the interior of the building, and more particularly partition plate using a natural paint containing the lacquer and jade components removed toxicity It relates to a coating method and a partition plate produced by the coating method.

In general, a partition used for an interior space of a building is a partition for dividing a given interior space efficiently so that a large number of users can utilize the interior space to the maximum, and various types are developed and widely used.

When the partition is described in more detail with respect to its structure and function, the basic shape of the partition is made to a certain standard, for example, forming a thickness of about 3cm to 8cm 110 to 60cm to 120cm length 110 It is produced variously in the size of about ㎝ ~ 180㎝, the basic component is composed of the partition body and the support for supporting the body.

The partition body is composed of a rectangular frame made of an angle frame of the "C" shape in cross section and a plate attached to the rectangular frame. The plate is attached to the plywood fabric using an adhesive, the fabric paper uses a variety of colors and various types of fabric structure. Due to this variety of fabrics, the plate forming the wall of the partition is developed in various colors and designs, satisfying the needs of buyers.

In particular, in the past, partitions could be used only in the horizontal direction, but in recent years, the partition body of a certain standard is vertically divided so that a plate with different colors of fabric paper can be attached to the square frame, thereby providing more various designs. Partitions have been developed, and it is also possible to divide a given space efficiently and use it as well.

However, the plate, which is a component of such a partition body, uses an adhesive generally used to attach fabric paper to plywood, which is a chemically harmful substance called form sick syndrome (formaldehyde, acetaldehyde, toluene, ethylbenzene, etc.). After the partition is installed, there is a problem that harms the health of workers working in a given indoor space due to the toxic substances generated in the partition.

In more detail, the partition constituting the plate material is made of plywood, and the plywood is manufactured by introducing an adhesive containing a chemically harmful substance in the manufacturing process, in particular, when the fabric paper is attached to the plywood adhesive By applying a large amount, there was a need to frequently ventilate due to the toxic substances generated in the adhesive.

In particular, when sensitive to these toxic substances, headaches occur, and work efficiency may be reduced, and these toxic substances may also cause respiratory and skin diseases, and the main causes of atopic skin diseases, which are recently becoming a social problem. The situation is attracting attention.

In addition to the release of toxic substances due to the adhesive used to attach the fabric to the plywood, harmful substances including normal dust are adsorbed on the tissue, such as mites and molds. Since breeding, there is a problem that provides a deadly working environment for the less immune workers.

Therefore, the conventional partition board does not meet the demands of users who prefer a more comfortable and comfortable working environment due to these problems, and also actively responds to the market environment that is required by replacing the quality of the partition board with an environment-friendly product. As a result, users were in dire need of improved, high-quality partition boards.

As such, the present invention, in order to solve such a problem, by applying a natural paint containing a lacquer component basically to the partition body, it is possible to block the external release of toxic substances contained in the production process of the plywood itself, In addition, it is possible to emit far infrared rays and negative ions to users, and to provide a method of coating a partition plate that can provide a comfortable and cozy indoor environment to users by implementing the color by the natural ingredients.

In addition, the present invention can be applied to the partition body using a natural paint basically contains a lacquer component, thereby preventing the external emission of toxic substances contained in the production process of the plywood itself, and also emits far infrared rays and anions to users Another purpose is to provide a partition plate that can provide a comfortable and cozy indoor environment to users by embodying the color by natural ingredients.

In the method of manufacturing a partition plate according to the present invention, after cleaning and preparing the surface of a regular standardized plywood, the method is configured by coating a coating thereon,

A first pre-coating step of a natural paint thinly coated on the surface of the clean surface treated plywood with a thickness of less than 1 mm of a natural paint containing a lacquer component, the toxicity of which has been removed;

A second coating process of the natural paint homogeneously or heterogeneously applying a natural paint containing a lacquer component from which the toxicity is removed to the surface of the precoated plywood in a thickness of 1 to 8 mm;

A tertiary coating process for applying a functional natural paint for finishing, using a functional natural paint containing a lacquer component and a functional additive, which is also toxic removed, on the surface of the secondary coated plywood;

A drying step of drying the coated plywood using the natural paint in a high temperature environment of 50 ° C. to 80 ° C. and a humid environment of 60 to 80% of relative humidity for 1 to 3 hours; It characterized in that it comprises a.

In addition, the partition plate according to the present invention is a conventional plywood body, and a surface treatment coating layer formed on the surface of the body and the components of the natural paint penetrated into the body; A natural paint layer formed on the surface treatment coating layer and composed of a lacquer component from which toxicity is removed; A functional natural paint layer formed on the natural paint layer and including a lacquer component, which is also toxic removed and a functional additive for releasing or providing a substance beneficial to the human body; It consists of.

As such, when manufacturing the partition plate according to the present invention, by preventing the release of substances harmful to the human body that may inevitably be included in the interior of the plywood to the surface, users living or working indoors with sick house syndrome There is an advantage that does not cause the same phenomenon.

In addition, when using the partition plate according to the present invention, since a large amount of far-infrared rays and anions are released by the jade and lacquer components included in the natural coating layer, it can be used as interior materials in consideration of the user's health There is also.

In addition, when using the partition plate according to the present invention, it is possible to configure a variety of colors of the partition. In particular, when using a vegetable color can be given a subtle color and texture from the partition product, there is an advantage that allows users to feel comfortable and comfortable working environment.

Hereinafter, with reference to the accompanying drawings, the present invention will be described in more detail. However, the accompanying drawings are only intended to describe the technical spirit of the present invention in more detail, and the technical spirit of the present invention is not limited thereto.

Exemplary Figure 1 is a block diagram for explaining a coating method of a partition plate according to the present invention, Figure 2 is a partial cutaway perspective view of the plate produced by the coating method of the partition plate according to the present invention.

One). Precoating process of adhesive natural paint on the surface of plywood:

The present invention includes a first pre-coating step of a natural paint to apply a thin coating of a natural paint containing a lacquer component is removed from toxicity to a surface of a clean surface treatment plate to a thickness of 1 mm or less.

The present invention, by using a regular standardized plywood, in order to form a natural paint layer containing a lacquer component, as a preparation step to clean the surface of the plywood and to prepare a clean. Here, although the plywood as an example of the material of the plate, this is one example, and when applying the coating method according to the present invention to the iron plate of the general wood or metal material can be obtained the same effect while preventing the corrosion of the material. The preparation step can be carried out in a conventional manner, and does not require any special skill.

The present invention forms a surface treatment coating layer 20 directly on the plywood 10 to be used as its basic substrate. The surface treatment coating layer 20 is formed between the plywood 10 and the natural paint layer 30, and strongly bonds the natural paint layer 30 to the plywood 10. It is formed as a mediator.

The present invention is to use a natural paint containing a lacquer component as a bonding medium in which the surface treatment coating layer 20 is formed, which is a technical feature of the present invention. In the present invention, the natural paint containing the lacquer component is preferably a natural paint using a non-toxic lacquer component so as not to cause side effects such as skin allergy by lacquer to the user.

In the present invention, the natural paint containing the above non-toxic lacquer component can be prepared by the following method, which is most preferred.

The present invention, in order to produce a natural paint containing the non-toxic lacquer component, in a weight ratio of 100: 2.5 ~ 10: 0.25 ~ 5 water as a diluent as a diluent in a kneading vessel having a constant capacity Weighing is added and heated to prepare a natural diluent, and the natural diluent: lacquer stock solution is weighed at a weight ratio of 100: 150 ~ 300 and mixed with each other to prepare a non-toxic lacquer.

In more detail, based on 100 Kg of water as a diluent, 2.5 Kg to 10 Kg of raw vegetables are weighed, added to the water, and heat treated. The heating temperature is raised to 100 ° C. and maintained at that temperature for 20 to 40 minutes before proceeding to the next step. The raw vegetables are one or two or more selected from the group consisting of radishes, onions, burdock and carrots, which are vegetables that can be harvested from the field and which contain a relatively large amount of water. When the raw vegetables are less than 2.5 Kg with respect to 100 Kg of water, it is difficult to ensure the non-toxicity of lacquer, while more than 10 Kg is not preferable because it does not significantly affect the non-toxicity.

The present invention is treated with the raw vegetables, then added a dry medicine, and also heat treatment. The present invention is based on 100 Kg of water as a diluent, weighing 0.25 Kg to 5 Kg of dry medicine, and heat treatment. The heating temperature is raised to 100 ° C. and maintained at that temperature for 20 to 30 minutes, and then the dried medicine is taken out. It is more preferable that the raw vegetables are taken out first, and then the dry medicine is added. The dry medicine means one or two or more selected from the group including sujijihwang (saengjihwang), licorice, oak, perilla (perilla). The dry medicine is used to further aid in weakening the toxicity of urushile in the lacquer component through the raw vegetables. When the dry medicine is less than 0.25 Kg based on 100 Kg of water as a diluent, the auxiliary effect is weak, whereas when it is more than 5 Kg, the synergistic effect is not proportional to the amount to be added. It's unpleasant.

The present invention is then added to the natural diluent: lacquer stock solution is weighed in a ratio of 100: 150 ~ 300, and mixed for 5 minutes to 20 minutes at room temperature, 40 to 70 minutes while heating to 80 ℃ to 100 ℃ again Preference is given to mixing for minutes. When the toxic lacquer stock is less than 1.5 times higher than the natural diluent, the content of the lacquer component is too low to prepare the natural paint, which makes it difficult to properly perform the function as a paint. If it is added more than 3.0 times as compared to the natural diluent, it is not preferable because it is difficult to sufficiently neutralize the toxic components. In the present invention, the use of natural lacquer, but the reason for removing the poison component in advance is to use the strong film-forming ability of the lacquer component, to prevent side effects such as causing skin allergy to users sensitive to lacquer.

<< Example 1 >>

20 Kg of water was poured into the heating vessel, and 550 g of radish and 300 g of onion were weighed and then added thereto, followed by stirring at 25 rpm for 20 minutes in boiling water. The radishes and onions were taken out, 100 g of ripening sulfur, 30 g of licorice, and 100 g of oak were weighed into the inside of the heating vessel, and the boiling state was continued for 20 minutes. After 20 minutes, the sucrose and licorice and the oak tree were taken out, 35 kg of lacquer stock solution was added thereto, and the mixture was stirred at 40 rpm for 10 minutes. Thereafter, stirring was continued at the same rate while heating and maintaining for 50 minutes in a boiling state. The final solution obtained was 45.5 Kg.

《Sensory test on nontoxicity》

Take 10 mg of the solution obtained in Example 1 above, drop it around 10 centimeters above the upper left cuff of 12 adults and observe for 2 days after the occurrence of allergy. It was.

However, none of the adults with the above solution had red rashes or itching of the skin on the wrists. As a result, it was confirmed that the lacquer processing solution according to Example 1 above neutralized the toxicity of the urushiol component.

The present invention is to produce a natural paint using the above non-toxic lacquer component, it is characterized in that it uses a natural paint prepared in the following manner.

To this end, in the separate kneading vessel, 40 to 70% by weight of water as a diluent, 0.05 to 0.2% by weight of cellulose thickener, 0.2 to 2.0% by weight of organic phosphate dispersant and 8 to 15% by weight of acrylic dispersant are used. After kneading, 12.8 to 51.75 wt% of the non-toxic lacquer is added thereto to prepare a natural paint containing the lacquer component.

In the present invention, in order to prepare a functional natural paint using non-toxic lacquer, 40 to 70 wt% of water to be used as a diluent and 0.05 to 0.2 wt% of a cellulose thickener are added to the inside of the kneading vessel. After the cellulose thickener is added, the mixture is slowly stirred for 1 to 10 minutes. If the above agitation process is not carried out, water and cellulose thickeners are not uniformly dispersed, so when the lacquer solution is administered later, partial entanglement has been observed.

In the present invention, as the cellulose thickener, an organic drug containing a cellulose component is suitable. Among them, hydroxy ethyl cellulose was found to be the most suitable. In this case, when the cellulose thickener is added at less than 0.05% by weight, the above tightness is partially generated, and when it is added at more than 0.2% by weight, the synergistic effect is weak compared to the dosage, which is not preferable. .

After the first stirring process, the present invention is added 0.2 to 2.0% by weight of the organic phosphate-based dispersant and kneaded for 2 to 10 minutes. As said organic phosphate type dispersing agent, the dispersing agent containing hydrogen phosphate, basic phosphate, and ortho phosphate is preferable.

In the present invention, an organic phosphate-based dispersant is added and kneaded, and then an acrylic dispersant is weighed in an amount of 8 to 15% by weight, followed by kneading. The acrylic dispersant is believed to increase the coating film forming ability of the coating by combining with the lacquer component that is added later, while its own component functions as a dispersant. When the acrylic dispersant is added in less than 8% by weight, the dispersing effect is weak, and when it is added in excess of 15% by weight, it is not preferable because it is considered to weaken the function as a natural paint by the lacquer component. The present invention is kneaded for 2 to 10 minutes after the acrylic dispersant is added. In kneading, it is preferable to knead more rapidly at the time of adding the acrylic dispersant than at the time of adding the organophosphate. As the acrylic dispersant, a high molecular compound containing an acrylic monomer is preferable.

In the present invention, the organic diluent is prepared in the kneading vessel, and then 12.8 to 51.75 wt% of non-toxic lacquer is weighed and added thereto. In this case, the non-toxic lacquer processing liquid includes a non-toxic lacquer component before adding the silk powder and a non-toxic lacquer component after adding the silk powder. In the latter case, since color treatment can be performed, it is more preferable in this respect. In the present invention, when the non-toxic lacquer processing liquid is used at less than 12.8% by weight, it is not preferable because the amount of lacquer as a natural paint is too small. You cannot use it.

In the present invention, the non-toxic lacquer processing liquid is introduced into the kneading vessel, and then the mixture is stirred at a low speed of 10 to 30 rpm for 1 minute to 5 minutes, and then at a highway of 40 to 180 rpm for 2 to 10 minutes. It is preferable to stir. In the present invention, when initially stirred at a speed of less than 10 rpm almost does not show a kneading effect, when kneading at a speed exceeding 30 rpm is not preferable because bubbles are generated due to excessive stirring. In addition, even when stirring at a speed of less than 40 rpm in the second half, the kneading effect is hardly seen, and when kneading at a speed exceeding 180 rpm, bubbles are generated due to excessive stirring, which is also undesirable. Defoamers can be used when foaming occurs with excessive stirring.

<< Example 2 >>

Pour 20 Kg of water into the heating vessel, add 50 g of hydroxyethyl cellulose as a cellulose thickener and 100 g of tetrapotassium pyrophosphate as an organic phosphate dispersant, stir at 10 rpm for 7 minutes, and at 15 rpm. Stir for 5 minutes. Thereafter, 500 g of polyacrylate and 3 Kg of styrene acryl were added thereto, followed by stirring at 20 rpm for 8 minutes. 7 kg of a lacquer processing solution obtained by the method of Example 1 was introduced into the heating vessel, stirred at 40 rpm for 2 minutes, and then stirred at 80 rpm for 8 minutes.

The solution of the finally obtained lacquer solution was observed to have a light yellow color due to a change in the initial brown color.

When the lacquer processing liquid was applied to the plywood with a brush, the surface shape of the plywood could be observed from the outside, and it was confirmed to form a very soft and smooth coating film.

In the present invention, it is preferable that the natural paint forming the surface treatment coating layer 20 is applied thinly on the surface of the clean surface treated plate member 10 to a thickness of 1 mm or less. The natural paint includes a lacquer component, which forms a firm film when exposed to air. In the natural paint forming the coating layer 20, the lacquer component, which is one of its main components, penetrates into the inside of the plate (plywood), while the natural paint layer 30 containing the lacquer component is formed on the surface thereof. Since it is formed, the function to firmly bond the natural paint layer 30 is performed primarily.

In addition, in the present invention, the coating layer 20 performs a secondary function of basically blocking the leakage of volatile components to the outside of the plate in the organic adhesive component used when manufacturing a conventional plywood. Therefore, since the thickness of the coating layer 20 is sufficient to perform this function, it is preferable in terms of economics to apply a thin coating to a thickness of 1 mm or less.

In the present invention, the coating layer 20 is preferably formed in a uniform thickness on the surface of the plate. Therefore, the method of forming the coating layer 20 may be formed to have a uniform thickness, and need not be specifically defined. However, the roller coating method using rollers was found to be the best method as the technical level of today. As a roller system, the board | plate material is moved between the roller stages which oppose each other, and the method of apply | coating both surfaces of a board | plate material, and the method of apply | coating the cross section of a board | plate material can be illustrated.

2). Secondary coating process of natural paints:

The present invention is formed on the coating layer 20 of the pre-coated plate, homogeneously or inhomogeneously apply a natural paint containing the lacquer component removed toxic to a thickness of 1 to 8 mm to form a natural paint layer 30 The secondary coating process is included.

In the present invention, it is preferable that the natural paint of the lacquer component from which the poison component is removed is prepared by the method described above. This is because it contains the same lacquer component, while being able to bind well with the coating layer 20 of the natural paint present thereunder, while having the ability to form a solid film by its own properties. In addition, since the lacquer component is known to have a property of absorbing electromagnetic waves, it is also intended to efficiently absorb various electromagnetic waves generated indoors by utilizing such properties.

In the present invention, the lacquer from which the poison component is removed is a sap collected by removing or partially removing the bark of the lacquer tree native to Korea and other foreign countries. It is known that urushiol is the main component in the sap of the lacquer tree, and it is known to cause skin allergy etc. by the urushiol component described above.

In the present invention, the secondary coating process is formed by applying on the coating layer 20, the coating method is not particularly limited. The technical feature of the present invention lies in the point of using a natural paint containing a lacquer component, because it does not have a technical feature in the coating method of the paint. Nevertheless, the above secondary coating process is more appropriate to proceed by the spray method.

In the present invention, the natural coating layer 30 formed by the secondary coating process may be formed homogeneously or inhomogeneously to a thickness of 1 to 8 mm. When the natural paint layer 30 is formed to be less than 1 mm, there is a risk that the function of the natural paint layer 30 due to the lacquer component is weakened, while when formed over 8 mm in terms of economic This is because it is not desirable.

In addition, in the present invention, when the natural coating layer 30 is formed in a homogeneous thickness, while providing a smooth surface to give a light feeling, it does not provide a three-dimensional feeling. On the contrary, when the natural paint layer 30 is formed in an inhomogeneous thickness, it does not provide a smooth surface because it does not provide a smooth surface, but provides a three-dimensional effect. Therefore, it is preferable to apply the above-described natural paint layer 30 in various forms as necessary to make use of the three-dimensional effect.

In the present invention, the roller coating method is preferable for forming the homogeneous surface, while the spray coating method is more preferable for forming the heterogeneous surface. Here, the spray coating method is a method of applying by spraying a natural paint with a spray gun, the spray gun is more preferably using a spray gun capable of spraying different colors. This is because when the natural paint is applied, various shapes can be formed by spraying the natural paint of different colors with different injection amounts and spray patterns.

In the present invention, the natural paint layer 30 is more preferably used a product containing a variety of colors. The present invention may be prepared by preparing a natural paint containing the non-toxic lacquer component, and then primary treatment with a high protein silk powder, and then adding calcium carbonate and pigments as inorganic color aids to impart color.

In the present invention, in order to implement a natural color in the natural paint layer 30, it is preferable to further process the non-toxicized lacquer component. To this end, a small amount of high protein silk powder is added to the non-toxic lacquer processing liquid. In the present invention, it is preferable to treat the non-toxicized lacquer processing liquid: silk powder in a weight ratio of 100: 0.1 to 2.0. At this time, when less than 0.1% of the silk powder was added as compared to the non-toxic lacquer processing solution, it was observed that dark brown was hardly changed from the lacquer processing solution, whereas when it was added more than 2.0%, it was light yellow. It was observed that it did not change significantly, which is undesirable.

The present invention is a natural paint treated with the silk powder: calcium carbonate is used in 100: 10 to 40 weight ratio, the natural paint treated with the silk powder: pigment is also used in 100: 5 to 40 weight ratio It is preferable. The calcium carbonate is a white powder, and converts the color of the natural paint to white at the same time, and performs a function of giving a basic color to add another color. When the calcium carbonate is less than 10% by weight, it is difficult to perform the function as the base color when adding another color later, and when it exceeds 40% by weight, it is not preferable because the other color is diluted.

In the present invention, the pigment is not limited to a specific pigment, since the pigment used for the general paint can be utilized as it is. However, given the well-being trend today, vegetable pigments with natural colors are more preferred. As the vegetable color, basic colors such as red, yellow, and green may be used, and the mixed colors may be mixed to produce a combined color. When adding a natural color to the natural paint layer 30, there is an advantage that users can select a variety of products, there is an advantage that can provide a more three-dimensional product. In addition, in the use ratio, when the pigment is less than 5% by weight compared to the natural paint, it is difficult to express its own color, and when it exceeds 40% by weight, the physical properties of the paint are weakened due to the use of excessive pigment. Not desirable The vegetable pigment may be used to extract the juice from the plant, but it is more preferable to purchase and use it in the market. In general, a small amount is added for the color close to the primary color, whereas a large amount is added for the color away from the primary color.

In the present invention, it is preferable that the natural coating layer 30 by the secondary coating process is repeatedly performed about 1 to 5 times. This is because coating at a certain time interval forms a more firm coating layer than spraying and drying a large amount of natural paint at once from the beginning. In addition, when forming a natural paint layer of different colors because it can produce a variety of shapes, such as the base base layer and the layer applied thereon, and the layer existing between them.

<< Example 3 >>

Pour 20 Kg of water into the heating vessel, add 70 g of hydroxyethyl cellulose as a cellulose thickener and 120 g of tetrapotassium pyrophosphate as an organic phosphate dispersant, stir at 10 rpm for 7 minutes, and at 15 rpm. Stir for 5 minutes. Thereafter, 450 g of polyacrylate and 2.5 Kg of styrene acryl were added thereto, followed by stirring at 20 rpm for 8 minutes. 7 kg of a lacquer processing solution obtained by the method of Example 1 was introduced into the heating vessel, stirred at 40 rpm for 2 minutes, and then stirred at 80 rpm for 8 minutes.

Thereafter, 20 Kg of the mixed lacquer processing liquid in the inside of the heating vessel was weighed, and this was poured into another cylindrical vessel, stirred for 5 minutes, and again, the calcium carbonate powder 5 was placed inside the cylindrical vessel. Kg was weighed in, and stirred at 40 rpm for 10 minutes. The final solution obtained was clear white.

3). Finish coating process of functional natural paints:

According to the present invention, after forming the natural paint layer 30 by the secondary coating, using the functional natural paint containing a lacquer component and a functional additive, which is also toxic removed thereon, the finishing layer 40 by the functional natural paint ), And includes a tertiary coating process for finishing.

In the present invention, the functional natural paint is preferably prepared to produce a natural paint containing the lacquer component, and then treated to be able to emit far infrared rays, or to express sterilization performance.

In the present invention, it is preferable to use fine jade powder in order to be able to radiate far-infrared rays from the coating after the coating treatment using a natural paint. The jade powder is most preferably domestic, and fine particles of about 600 to 1000 mesh are preferably used. When the jade powder exceeds 600 mesh, the particle size of the particles is large to weaken the tensile force of the coating film, while when the jade powder is less than 1000 mesh, the processing cost is relatively large and economic efficiency cannot be reached.

In the present invention, it was observed that the jade powder can be used in the range of 30 to 300% by weight of the natural paint. If the jade powder is less than 30%, far-infrared radiation efficiency is too low, and if it exceeds 300%, the coating performance of the natural paint is hindered, so the range of 30 to 300% is preferable.

<< Example 4 >>

20 Kg of the lacquer work solution obtained in Example 3 was weighed, and 10 Kg of domestic jade powder (600 mesh) was poured thereto, stirred at 20 rpm for 10 minutes, and stirred at 40 rpm for 15 minutes. , Was stirred at 80 rpm for 8 minutes. The final product was observed as a clear white solution.

4). Plywood Drying and Encapsulation Process:

The present invention is a drying and film forming process of plywood for drying for 1 hour to 3 hours in a high temperature environment of 50 ℃ to 80 ℃ and a humid environment of 60 to 80% relative humidity using the above-described natural paints It is included.

The present invention is to provide a functional plate in which the plate produced in various forms from above into a drying chamber to finally form a smooth and solid film.

In the present invention, the drying chamber has a high-temperature environment of 50 ° C to 80 ° C, and a relative humidity of 60% to 80%. If the room temperature of the drying chamber is less than 50 ℃ not enough drying within a given temperature and time range, if it exceeds 80 ℃ not only the drying efficiency is lowered, but also economically unfavorable. In addition, when the relative humidity inside the drying chamber is less than 60%, it is not preferable because the drying time takes too much time, and the surface roughness tends to be severe after drying, and similar tendency occurs when the relative humidity exceeds 80%. .

In the present invention, the plate formed with the natural paint layer 30 inside the drying chamber is put in the drying chamber, and then stays for 1 to 3 hours. This is because it is not sufficiently dried when staying in the drying chamber for less than 1 hour, whereas it is already sufficiently dried when staying for more than 3 hours, and thus it is not necessary to stay any longer.

The present invention is installed by installing a conveyor belt in the interior of the drying chamber, by placing a plate formed with a natural paint layer 30 on the conveyor belt, and then adjust the time taken from the beginning to the last time to 1 hour to 3 hours, automatic It is desirable to carry out the drying process. This is because the drying process can be performed by a continuous process.

<< deodorization test of the board of the present invention >>

The inventors formed the natural paint layer 30 using the lacquer processing liquid obtained in Example 3, and then manufactured the plate according to the present invention by the drying process, in order to test the performance of the plate, Deodorization test was requested.

The test organization regarding the deodorization was conducted by the Korea Institute of Building Materials. TEL (02) 3415-8880], and the test method was carried out according to the above-described method by the test institute (KICM-FIR-1085).

Figure 3 is a graph showing the results of the deodorization test of the natural paints according to the present invention. The results of the deodorization test are summarized in Table 1 below.

 Test Items             Deodorization Test (HCHO)  Elapsed time (minutes)  Blank concentration (ppm)  Sample concentration (ppm)  Deodorization rate (%)   Test result      0       82       82     -     30       79       24    69.6     60       76       20    73.7     90       73       18    75.3    120       70       16    77.1  Test Methods            KICM-FIR-1085

As can be seen from Table 1, it can be seen that the plate according to the present invention almost absorbs the formaldehyde (HCHO) component distributed in the room. This means that when the plate according to the present invention is installed in the interior of a building in the form of a partition, it absorbs harmful components that may be spread in the interior space.

In addition, the present invention is based on this fact, the volatile components of the adhesive component of the plywood corresponding to the raw material of the plate is not emitted to the outside, it can be blocked by the coating layer 20, even if the coating layer 20 Even though it passes through), it means that it is absorbed by the natural paint layer (30).

Therefore, the present invention can indirectly confirm that no harmful components can be released from the plywood which is the raw material of the plate.

《Appearance of plate formed with natural paint layer》
