The present invention relates to a method for producing a coating film and to a coating film prepared accordingly, and more particularly, to a method for producing a laminating coating film that can be released in the far infrared and anion to help promote health and produced accordingly It relates to a coating film.

In general, important photographic or document materials that require wrinkle prevention, waterproofing, or long-term storage are coated and coated with coated film. The laminating coating film is coated with an AC agent (adhesive agent) on a base film (BF) such as a polyester (PET) film, and then extruded through a T-shaped die (hereinafter referred to as 'T die'). It is prepared by coating molten resin such as PE) or ethylene vinyl acetate (EVA).

When the coated paper such as a photo or paper is coated using the laminating coated film paper, not only the moisture penetration into the coated paper is blocked, but the laminated coated film paper prevents the physical damage of the coated paper. The advantage is that the document data can be stored for a long time without damage.

However, since all of these laminating coating film papers use synthetic resin as a raw material and the coating is generally performed by thermal fusion, the coated product may have a bad smell of synthetic resin or chemical components that are not good for human body. There are disadvantages that are usually not environmentally friendly.

The present invention was devised to solve the shortcomings of the conventional laminating coating film paper as described above, the method for producing a laminating coating film that can help to promote health by releasing far infrared rays and anions, and the laminating film produced accordingly It aims to provide.

The objects and advantages of the present invention will be described in more detail below, and will be further embodied by the examples. Furthermore, the objects and advantages of the present invention can be realized by the means indicated in the claims and combinations thereof.

Here, the far-infrared emission mineral mixed in the molten resin extruded to the base film is preferably selected from the group containing tourmaline, alumina-based minerals, cordierite-based, alumina silicate-based minerals.

In addition, it is preferable to further include a corona treatment step of forming an unevenness on the surface of the base film by forming a corona discharge on the surface of the base film to improve adhesion between the base film and the AC agent before applying the AC agent.

In addition, before extruding and coating the molten resin and the far-infrared emission mineral mixture on the base film, it is preferable to further include an ozone treatment step of spraying ozone on the surface of the mixture to improve the adhesion between the mixture and the base film.

On the other hand, the AC coating step and the extrusion step is preferably carried out twice.

Include.

According to the present invention as described above, as the material of the component generating far infrared rays and anions is multi-laminated in the film paper, a large amount of far infrared rays and anions are generated during coating and use to have an excellent effect that can help to promote health.

Hereinafter, the method for producing the far-infrared and anion-emitting laminating coating film according to the present invention and the specific configuration of the coating film produced according to the present invention will be described in detail with reference to the accompanying drawings.

 1 shows a process flow diagram of the process for producing far-infrared and anion-emitting laminating coating films according to the invention, and FIG. 2 shows each process step of the coating film in a schematic diagram.

 As shown in Figures 1 and 2, the method for producing the far-infrared and anion-releasing laminating coating film according to the present invention includes a base film unwinding step, an AC coating step, a drying step, an extrusion step and a film winding step.

As a first step, the base film unwinding step is a step of taking out the base film BF wound in a roll form by rotating the unwinder 1 as shown in FIG. 2. The base film BF unwound from the unwinder 1 is sequentially transferred to each process step while engaging a plurality of rollers described later. The base film used in this step is preferably a polyester film, as mentioned above.

As a second step, the AC agent applying step is a step of applying the AC agent acting as a kind of adhesive on the base film upper layer. As already mentioned, the manufacture of the laminating coating film usually adopts a method of laminating the molten resin to the base film by extrusion, and in the case of laminating the molten resin, in order to increase the adhesion between the resin and the base film, it is usually use.

The AC agent is not limited to the type of AC agent used in the present invention, such as an organic titanium and polyethylene imine AC agent, an aqueous urethane AC agent, a polybutadiene-based modified polymer aqueous AC agent, and water and methanol are used as diluents. do.

Meanwhile, the AC agent according to the present invention further includes mica (mica) and tourmaline capable of emitting far infrared rays and anions. The mica and tourmaline can remove far-infrared rays and negative ions to remove heavy metals and toxic gases, have antibacterial and antiviral effects, and remove chemical odors, which is a problem of coating films composed only of synthetic resins, and help improve health.

The mica and tourmaline are preferably mixed and added to the AC agent in liquid form. The mixing ratio of the AC agent is preferably mixed at a ratio of 5 kg of water, 5 kg of mica, 2 kg of tourmaline, and 1 kg of methanol per 1 kg of AC agent.

In the present AC agent applying step, a corona treatment step is further performed to improve adhesion between the base film and the AC agent. The surface treatment step is a process of non-flattening the surface of the base film so that the AC agent adheres well to the base film. The corona discharge is generated by applying a high voltage of 22,000V to the corona discharge device to form irregularities on the surface of the base film. In this way, if the irregularities are formed on the surface of the base film to improve the surface roughness, the adhesion area and frictional force between the AC agent and the base film surface is increased, so that the AC agent can be uniformly applied with a strong adhesive force throughout the base film. .

The present AC agent applying step is performed by a coating method of passing the base film through the AC roller 3 deposited in the AC storage container 2, as shown in FIG. In this coating method, two or more rollers (AC rollers) are used to uniformly apply the surface of the base film after controlling the amount of AC agent by varying the intervals, rotation speeds, and directions of each roll. In the present invention, although the coating method is used as a preferred embodiment, there is no particular limitation on the method of applying AC agent, and the AC agent is applied to the deposition method or a spray gun on the surface of the base film by dipping the base film itself onto the AC agent. It is also possible to use the spray method of spray coating.

As a third step, the drying step is a step of drying the liquid AC agent applied to the base film surface. In this drying step, as shown in Fig. 2, the AC agent is dried by passing through the drying chamber 4 while sequentially transferring the base film coated with the AC agent by a plurality of rollers.

As a fourth step, the extrusion step is a step of extrusion coating the molten resin onto the base film to which the AC agent is applied and dried. As mentioned above, the molten resin is extruded using the T die 5. The molten resin used in this step is preferably polyethylene (PE) resin or ethylene vinyl acetate (EVA) resin.

Further, in the present invention, the far-infrared emitting mineral component is mixed with the polyethylene resin or the ethylene vinyl acetate molten resin. The far-infrared emission mineral component mixed with the molten resin is preferably selected from tourmaline, alumina-based, cordierite-based and alumina silicate-based minerals. The far-infrared emitting mineral component is preferably pulverized by a mill and added in fine powder form. The molten resin and the far-infrared emitting mineral are preferably blended in a weight ratio of 4: 1, that is, the ratio of 80% by weight of the molten resin and 20% by weight of the far-infrared emitting mineral. When the far-infrared emitting mineral is blended in less than 20% by weight, the far-infrared emissivity and the radiant energy are too low to be effective, and when it exceeds 20% by weight, too much far-infrared is emitted, which is rather undesirable.

As shown in FIG. 2, the molten resin extruded through the T die 5 is applied to the base film surface passing between the pressing roll 6 and the cooling roll 7, and the hot molten resin is pressed into the pressing roll. (6) is pressed and applied to the AC agent previously applied to the surface of the base film, and the AC agent dried in this process is pressed by the pressing roll 6 while being melted again by the heat of the molten resin, so that the AC agent and the molten resin Molten resin is laminated to the base film while maximizing adhesion.

On the other hand, it is preferable to further perform an ozone treatment step of injecting ozone to the surface of the mixture during extrusion of the molten resin and far-infrared emission mineral mixture. The ozone treatment process is a process performed to improve the adhesion between the mixture of the molten resin and the far-infrared emission mineral extruded from the T die 5 and the base film, and as shown in FIG. 3, an outlet to the T die 5 is shown. And melt ozone generated through the ozone generator 9 in a section (A; air gap, hereinafter referred to as 'air gap') to a position where the base film is laminated by the pressing roll 6 and the cooling roll 7. Spray to the surface of the mixture of the resin and the far infrared emitting mineral.

In a typical extrusion process, an air gap is placed between the exit of the T die 5 and the pressing roll 6 so that the molten resin is naturally oxidized and activated by oxygen in the air, or the extrusion temperature is lowered to lower the melt viscosity. The method of improving wettability by improving wettability was used. In the present invention, by promoting the oxidation by injecting ozone to the surface of the mixture of the molten resin and the far-infrared emission mineral in the air gap to improve the adhesion between the base film and the resin.

Through this method, a laminating coating film that emits far infrared rays and anions can be completed. In the present invention, in order to further increase the emissivity of far infrared rays and anions, as shown in FIGS. 1 and 2, a single extrusion-laminated base film It is preferable to carry out the extrusion laminating process again to the surface. In other words, the AC film containing mica and liquid tourmaline, which emits far infrared rays and anions, is applied to the base film on which extrusion extrusion is completed once, and then dried, and the upper layer is dried again with a molten resin and a far infrared ray emitting mineral mixture. Secondary extrusion.

As a final step, the final laminating coating film, which has been completed through all the process steps, is wound by rewinder and shipped in roll form, or after a separate cutting operation, and then shipped.

FIG. 4 shows the layered structure of the far infrared and anion releasing laminating coating film produced by the method as described above. As shown, the first AC layer 20 is formed on the polyester base film layer 10, the first resin layer 30 is bonded to the upper layer of the first AC layer 20, the first resin The second AC layer 40 is formed on the upper layer 30, and the second resin layer 50 is formed on the upper layer of the second AC layer 40. In such a laminated structure, since each AC agent layer and the resin layer contain far infrared rays and anion emitting components, a large amount of far infrared rays and anions are released from the coating film according to the change in human body temperature or room temperature.

Far infrared and anion emission tests were performed to test the performance of the laminating coating film prepared by the method as described above.
