Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of manufacturing a decorative sheet using a non-

TECHNICAL FIELD The present invention relates to a method of manufacturing a decorative plate.

Particularly, door panels for interior decoration, interior panels, particle board, medium density fiberboard (MDF), high density fiberboard (HDF)

The surface of such a decorative plate is formed with various patterns, thereby enhancing aesthetic value. There are various ways to form the pattern on the surface of the decorative plate. For example, a veneer may be attached, a film printed with a pattern may be attached, or a three-dimensional pattern may be formed on the surface of the decorative plate by using a roller.

Particularly, a method of forming a three-dimensional pattern on the surface of a decorative plate has conventionally been widely used by a roller. SUMMARY OF THE INVENTION The present invention has been made in order to solve problems occurring in such a roller processing method.

A method of forming a three-dimensional pattern on the surface of a decorative plate is a method of forming a paste-like material obtained by mixing a wood pulp and an adhesive agent called so-called ooze on the surface of the particle board, MDF, HDF, plywood, And pressed by a roller to form a machining layer having a constant thickness. Then, a processing roller having a three-dimensional pattern formed on its surface is heated to a high temperature to press the processing layer to form a three-dimensional pattern on the surface of the base plate. An example of a decorative plate manufactured in this manner is disclosed in Japanese Patent Laid-Open No. 2007-0117844.

In such a conventional method, there is a problem that the cost of processing a three-dimensional decorative pattern on the surface of the roller is too high. Generally, the cost for producing a roller having a three-dimensional decorative pattern is 10 million to 15 million won. In recent years, however, the need for small quantity production of various types of products has been increasing. Therefore, in the case of manufacturing expensive roller molds and producing decorative plates, costs of manufacturing costs are excessively high at a small business site. Further, when a three-dimensional pattern is formed by a roller mold, it is difficult to form a specific pattern at an accurate position. This is because the position error is generated because the pattern formed on the rotating roller must be transferred to the surface of the planar plate material. In addition, when three-dimensional patterns are formed on the surface of the decorative plate by the roller, there is a problem that the decorative plate is bent due to uneven pressure applied to the decorative plate.

It is an object of the present invention to provide an improved decorative sheet material which can remarkably reduce the manufacturing cost and significantly increase the degree of freedom of design so as to efficiently produce a small number of decorative sheet materials of various kinds, Method.

According to another aspect of the present invention, there is provided a method of manufacturing a decorative plate using a non-metallic mold, the method comprising: applying a paste-like material mixed with wood and an adhesive to a surface of a wooden plate, A base plate material preparing step of preparing a base plate material having a layer;

A pattern plate member preparation step of preparing a nonmetallic pattern plate member having a three-dimensional pattern formed on the surface of a wooden board or a high-pressure melamine conversion plate (HPM); And

The base plate member and the patterned disk member are pressed in a direction in which the base plate member and the patterned disk member are brought close to each other while the press is heated so that the processed layer of the base plate member faces the patterned disk member, And a pattern transferring step of transferring the pattern onto the base plate material.

The pressing time of the press in the pattern transferring step is preferably from 30 seconds to 3 minutes.

The finishing foil or the veneer may be adhered to the surface of the base plate material with an adhesive before the pressing of the press in the pattern transferring step, and then the pressing can be performed by a press.

The surface of the processing layer of the base plate material may be coated with an ultraviolet ray paint before pressurizing the press in the pattern transferring step, and then pressurized with a press.

The wood used as the pattern disc member is preferably any one of a wood, a medium density fiberboard (MDF), a high density fiberboard (HDF), a particle board (PB), and a plywood.

The method of manufacturing a decorative plate using a non-metallic mold according to the present invention is advantageous in that manufacturing cost of a decorative plate can be remarkably reduced by using wood or a high-pressure melamine plate without using a metal mold of a flat plate as well as a roller mold Thereby providing an effect of significantly increasing the degree of freedom of design of the decorative plate pattern. In addition, the method of manufacturing a decorative plate using a non-metal mold according to the present invention provides an effect of providing a decorative plate with high quality by eliminating the problem of bending of the processed decorative plate. In addition, the method of manufacturing a decorative plate using a non-metal mold according to the present invention has an advantage of eliminating the problem that the decorative plate is bent after patterning by molding with a flat metal mold.

Referring to FIGS. 1 to 5, a method 10 for manufacturing a decorative plate using a non-metal mold according to a preferred embodiment of the present invention (hereinafter referred to as a "method of manufacturing a decorative plate" , A pattern plate member preparation step (S20), and a pattern transferring step (S30).

The base plate material preparation step S10 includes preparing a base plate material 10 having a machining layer 15 formed by applying a paste material having a mixture of wood and an adhesive to a predetermined thickness on the surface of a wooden plate material. The wood used in the base plate preparing step S10 may be selected from wood, plywood, medium density fiberboard (MDF), high density fiberboard (HDF) and particle board (PB). The processing layer 15 formed in the base plate material preparing step S10 is formed by applying a paste-like material called a so-called "puddle" to a predetermined thickness using the roller 200 as shown in FIG. The working layer 15 may be made of a material mixed with an adhesive agent and wood pulp, and may be made of a material widely used as an interior molding material for a building. The hardness of the working layer 15 is generally lower than that of the base material of the base plate 10. [ Therefore, the portion where the pattern is transferred and formed by the pressure of the press 30 in the later-described pattern transferring step S30 is the processing layer 15.

The patterned disk member preparation step S20 processes a three-dimensional pattern on the surface of a woodcut board or a high-pressure melamine board (HPM). The wood board may be selected from wood, plywood, medium density fiberboard (MDF), high density fiberboard (HDF), particle board (PB) and the like. The high-pressure melamine laminate plate is a well-known material, which is impregnated with a thermosetting resin (for example, phenol resin) on a paper or fibrous base material and has a plate-like shape formed at a pressure of 35 to 50 kgf / It refers to the material. CNC machining or manual work can be employed as a method of forming the three-dimensional pattern (25) on the surface of the wood block or the high-pressure melamine facet in the pattern disk member preparation step (S20). The cost required for the pattern plate member preparation step (S20) is considerably lower than that of a metal mold (for example, carbon steel, stainless steel, aluminum, etc.) which is a conventional mold. For example, in the case of manufacturing a metallic metal mold having a size of 1220 mm (W) X2440 mm (L) X6 mm (H), a cost of approximately 10 million to 15 million won is required. However, the cost required for preparing the pattern disc member (S20) is about 100,000 won. As described above, in the case of employing the pattern disk member preparation step (S20) according to the present invention, a remarkably inexpensive cost structure can be achieved as compared with the conventional method. In addition, since the material used in the pattern disc member preparation step S20 is not made of metal, it is easy to process and the degree of freedom to realize the pattern pattern is remarkably increased compared to the conventional case.

In the pattern transferring step S30, the processing layer 15 of the base plate 10 is loaded on the press 30 so as to face the pattern disk member 20. [ It is preferable that the press 30 uses a press which is pressed upward and downward with respect to the paper surface. In the pattern transferring step S30, the presser 30 is pressed in a direction in which the base plate member 10 and the pattern disc member 20 are brought close to each other in a heated state. In the pattern transferring step S30, a pattern processed on the pattern disc member 20 is transferred to the base plate member 10. [ In the pattern transferring step S30, the heat heated by the press 30 is transferred to the processing layer 15 of the base plate 10 to increase the degree of flow of the adhesive constituting the processing layer 15 Thereby facilitating the transfer of the pattern to the processing layer 15. [

The pattern disc member 20 may be disposed on the upper side of the base plate 10 and vice versa. It is further preferable that the pattern disc member 20 is disposed on the upper side of the base plate member 10 so that the base plate member 10 can be easily moved for painting or drying after the pattern transferring step S30.

In the pattern transferring step S30, the heating temperature of the press 30 is preferably maintained at 50 캜 to 100 캜. If the heating temperature of the press 30 is less than 50 ° C, the adhesive of the working layer 15 does not have sufficient fluidity and the pattern transfer does not occur smoothly. On the other hand, when the heating temperature of the press 30 is higher than 100 ° C, the risk of the working environment is increased and the degree of flow of the processing layer 15 becomes too large and the quality of the transferred pattern deteriorates .

In the pattern transferring step S30, the pressing time of the press 30 is preferably maintained at about 30 seconds to 3 minutes. When the pressing time of the press 30 is less than 30 seconds, the pattern of the pattern disc member 20 is not transferred to the base plate 10 properly. On the other hand, when the pressing time of the press 30 exceeds 3 minutes, the degree of transfer of the pattern of the pattern disc member 20 to the base plate 10 is saturated, and unnecessary production cost is increased .

An adhesive may be applied to the surface of the base plate 10 with a spray or a roller before the press 30 is pressed in the pattern transferring step S30 and the finishing foil or the veneer may be adhered to the surface of the base plate 10, have. In this case, since the finishing foil or the veneer serves as a finishing material, there is an advantage that the decorative property of the decorative plate 100 produced by the present invention can be improved. Particularly, the finishing foil or veneer does not stretch well during processing, which is difficult to process at room temperature. However, when the bonding is performed in the same process as the pattern transfer using a heated press as in the present embodiment, smooth adhesion and processing are advantageous.

In the pattern transferring step S30, the surface of the processing layer 15 of the base plate 10 is coated with an ultraviolet ray coating (UV coating) before the pressing of the press 30, can do. In general, UV coating can be applied only to the smooth surface like the mirror surface. Therefore, it is impossible to apply the UV coating on the surface of the decorative plate processed with three-dimensional pattern. However, as in the present embodiment, if the UV coat is coated on the surface of the processing layer before transferring the pattern onto the processing layer 15, and then the pattern is transferred by pressing with the heated press 30, And the pattern is transferred in a state in which the curing of the UV paint is not completely performed. Thus, there is an advantage that smooth processing can be performed.

Hereinafter, advantageous effects of the method of manufacturing a decorative plate according to the present invention constructed as described above will be described in detail.

As described above, the greatest merit of the method of manufacturing the decorative plate according to the present invention is that by using a wood or high-pressure melamine reed plate which is easy to process and low in manufacturing cost without using a conventional metal mold, Is significantly reduced compared to the prior art, thereby increasing the productivity.

In addition, since the patterned disc member 20 made of a nonmetallic material is easy to process, the degree of freedom of pattern design is increased, and various types of designs can be realized.

Further, since the pattern disc member 20 is easier to process than a metal mold of the related art, the processing time can be remarkably shortened. For example, although the time required for manufacturing the conventional metal mold is more than one week, the time for preparing the pattern disc member 20 according to the present invention is sufficient for one day.

In addition, the pattern disc member has a condition suitable for producing a small quantity of various kinds of products. In other words, as the adoption of decorative patterns that have been made uniform in recent years is reduced and the tendency to produce and supply a small amount of decorative plate materials of various patterns matching with the sensitivity of consumers is increasing, manufacturing of the pattern plate member as a non- It is very desirable in terms of cost reduction and meeting consumer needs.

Further, in the method of manufacturing a decorative plate according to the present invention, the patterned circular plate member as a flat plate member is evenly pressed to the front surface of the base plate by a heated press. Therefore, there is almost no deviation in the pressure applied to the base plate material. As a result, there is an advantage that the problem that the manufactured decorative plate is bent is solved compared with the conventional method in which the pattern transfer is performed by the roller mold.

Further, in the method of manufacturing a decorative plate according to the present invention, the processing layer primarily formed by the rollers in the preparation step of the base plate joins fine grain particles with an adhesive to form a layer, And the outer surface is smoothly formed to facilitate the post-processing, thereby improving the quality of the decorative plate and reducing the defect rate.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but many variations and modifications can be made by those skilled in the art within the technical scope of the present invention. Is obvious.
