Description
The present invention relates to a method for manufacturing a high gloss thermoplastic film-coated embossed panel, and more particularly, to a method for manufacturing a high gloss thermoplastic film coated embossed panel, which comprises the steps of forming an unsaturated polyester coating layer and a high- It is possible to prevent the release of toxic volatile organic substances into the room when the panel is used in furniture or the like, and at the same time, it is possible to prevent deodorant polyester coating layer and high-gloss thermoplastic film coating layer from deep and clear duotone To a method of manufacturing an environmentally friendly high gloss thermoplastic film coated emboss panel capable of forming a three-dimensional emboss.
The unsaturated polyester resin is a kind of thermosetting resin and is a synthetic resin well known to those skilled in the art as a surface coating material due to its high gloss and hardness. A film coating method is used as a kind of a high gloss coating method which is a method of coating a high gloss coating material on the surface of a board such as MDF (medium density fiber board). In the film coating method, an unsaturated polyester resin paint And then a release film is attached thereon. Then, the release film is pressed by using a roller or the like to form a certain unsaturated polyester film on the surface of the board. The unsaturated polyester resin used in the film coating method is a liquid resin prepared by synthesizing an unsaturated group-containing acid such as maleic anhydride or fumaric anhydride with a polyhydric alcohol (glycol). When used for coating a board, 25% by weight to 50% by weight of a styrene monomer, which is an aromatic vinyl derivative, is added as a reactive diluent in order to improve curability while maintaining high-gloss physical properties. Styrene monomers have the advantage of being compatible with unsaturated polyesters and serving as diluents, as well as crosslinking and curing unsaturated polyesters within a short period of time (at least 24 hours at room temperature and atmospheric pressure). In this process, the styrene monomer is copolymerized with the unsaturated polyester. However, the styrene monomer always remains a styrene monomer that does not participate in the crosslinking reaction even after the unsaturated polyester coating layer is cured, and the styrene monomer remaining in the styrene monomer is gradually released outside for a long time, causing various problems.
The biggest problem is that volatile organic compounds (VOCs), which remain in the unsaturated polyester coating layer and emit styrene monomers, are toxic. Therefore, in recent years, regulations on the release of styrene monomers to the atmosphere have become strict due to environmental problems, and the demand for not only high-grade furniture having an unsaturated polyester coating layer but also supply thereof is remarkably reduced.
In addition, when the styrene monomer is vaporized in small quantities while remaining in the unsaturated polyester coating layer, the gloss of the unsaturated polyester coating layer deteriorates over time and the discoloration (yellowing) of the unsaturated polyester coating layer progresses, There is a problem that fine cracks are generated in the polyester coating layer. The occurrence of these problems involves some degree of vaporization of the styrene monomers remaining in the unsaturated polyester coating layer without participating in the crosslinking reaction.
Korean Patent Laid-Open Publication No. 10-2015-0103885 discloses a flat plate-like furniture member, a transparent PET film disposed on the top of the plate member, and a PET film disposed between the upper surface of the plate member and the PET film, Wherein the adhesive resin is composed of an unsaturated polyester resin having adhesiveness, the adhesive resin being bonded to an upper surface of the plate member.
Korean Unexamined Patent Publication No. 10-2015-0103885 When the PET film is adhered to the unsaturated polyester resin as in the invention, the vaporization emission of the styrene monomo can be blocked to some extent. However, since the styrene monomer remains in the unsaturated polyester even in the state that the PET film is adhered, the styrene monomer is gradually released to the side or the like for a long time. That is, attaching the PET film only increases the release time of the styrene monomer.
In addition, according to Korean Unexamined Patent Publication No. 10-2015-0103885, it is possible to manufacture only a flat panel type PET coated panel, and it is impossible to manufacture an emboss panel in which a three-dimensional emboss is formed on the surface. Unsaturated polyesters are thermosetting, while PET films are thermoplastic. Therefore, when the unsaturated polyester is once cured by attaching the PET film to the plate by the unsaturated polyester, even if the surface of the PET film is pressed with a mirror-finished plate having an embossed shape, the cured unsaturated polyester layer hardly deforms, The film is temporarily thermally deformed according to the emboss shape of the mirror-surface plate, and then, after a lapse of time, it is mostly restored to its original state. Therefore, since the flat PET film-coated panel is a structure in which a transparent PET film is laminated again on the transparent unsaturated polyester layer, the color and pattern of the board surface are exposed to the outside as it is, and the double coating of unsaturated polyester and PET film Dimensional stereoscopic effect, two-tone effect, and the like can not be expressed.
The present invention has been made in order to solve the problems of the conventional high gloss thermoplastic film-coated emboss panel as described above. The first problem to be solved by the present invention is to provide a method of forming a high gloss thermoplastic film coating layer, A large amount of styrene monomer, which is a harmful volatile organic compound added for crosslinking to unsaturated polyester in a short time within seconds (seconds) to several minutes (minutes), is massively removed, and when a high gloss thermoplastic film-coated emboss panel is used for furniture etc., harmful volatile organic compounds And a method for manufacturing an environmentally friendly high-gloss thermoplastic film-coated emboss panel which can prevent it from being released into the room.
A second problem to be solved by the present invention is to provide an embossed embossed embossed embossed on a surface of a board on which a double coating layer of an unsaturated polyester and a thermoplastic film is formed, And a method of manufacturing an environmentally friendly high gloss thermoplastic film-coated emboss panel capable of exhibiting a two tone effect.
A third problem to be solved by the present invention is to provide an environmentally friendly high gloss coating capable of realizing a variety of stereoscopic patterns with high gloss on a panel surface in which an embossed shape is formed deeply and clearly on an unsaturated polyester coating layer and a high gloss thermoplastic film coating layer, And to provide a method of manufacturing a thermoplastic film-coated emboss panel.
A first object of the present invention is to provide a method for manufacturing a board, which comprises: a smoothening layer forming step of smoothening and planarizing a surface of a board; a step of adding a styrene monomole as a hardening agent to an unsaturated polyester in a paste state, An unsaturated polyester to which a high-gloss thermoplastic film is adhered while applying an unsaturated polyester to a surface of the board in a uniform thickness by pressing the upper part of the high-gloss thermoplastic film by a roller after laminating a high-gloss thermoplastic film on the unsaturated polyester An unsaturated polyester semi-curing step of semi-curing the unsaturated polyester at room temperature and normal pressure in a state in which a high-gloss thermoplastic film is adhered, and a step of forming a semi-cured unsaturated polyester coating layer and a high-gloss thermoplastic film coating layer by embossing The resulting mirror-polished plate was hot-pressed at 145 ° C to 200 ° C under a condition of 5 kgf / cm 2 to 100 kgf / cm 2 for 1 second to 180 seconds to thermally cure the semi-cured unsaturated polyester coating layer and heat the residual styrene monomer from the semi-cured unsaturated polyster Unsaturated polyester coating layer that emulsifies the embossed mirror plate on the unsaturated polyester coating layer and the high-gloss thermoplastic film coating layer while releasing the fluorine-containing polyester coating layer and the high gloss thermoplastic film coating layer. .
As the high-gloss thermoplastic film, a PET (polyethylene terephthalate) film or an ASA (Acrylic Styrene Acrylonitrile) film can be used.
The present invention has the following effects.
1) The unsaturated polyester coating layer and the high-gloss thermoplastic film coating layer are thermocompression-bonded at a pressure of 5 kgf / cm 2 to 100 kgf / cm 2 at a temperature higher than the vaporization temperature (145 ° C) of the styrene monomer to thermally crosslink the unsaturated polyester by heat And simultaneously vaporizing and discharging the styrene monomers that have not participated in the crosslinking reaction. At the same time, it is very deep and clear to the unsaturated polyester coating layer and the high-gloss thermoplastic film coating layer, and at the same time, It is possible to form an emboss having a peculiar stereoscopic effect and a two-tone effect which can be obtained.
2) In a process of forming an unsaturated polyester coating layer and a high-gloss thermoplastic film coating layer on a board, a large amount of residual styrene monomer, which is a volatile organic compound (VOC) added for crosslinking to an unsaturated polyester, It is possible to prevent the release of toxic volatile organic substances into the room.
3) Thermosetting the semi-cured unsaturated polyester coating layer and the high-gloss thermoplastic film coating layer with a mirror-finished plate embossed not only enlarges the styrene monomer emission area but also causes the molecules of the thermoplastic film to flow so that the styrene monomer can easily And the embossed polyester film is completely cured after the embossing of the deep and clear shape on the unsaturated polyester application layer and the high gloss thermoplastic film coating layer so that the embossing formed on the high gloss thermoplastic film is restored to the original state to prevent the embossing .
4) It is possible to maintain the gloss of the unsaturated polyester coating layer and the high-gloss thermoplastic film coating layer for a long time and to prevent the discoloration (yellowing) of the unsaturated polyester coating layer and the high-gloss thermoplastic film coating layer, It is bonded to the high-gloss thermoplastic film to prevent the occurrence of cracks. Therefore, the quality of the unsaturated polyster-coated furniture is drastically improved, thereby increasing the demand for the unsaturated polyster-coated furniture.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a method for manufacturing an environmentally friendly high gloss thermoplastic film-coated embossed panel according to the present invention will be described in detail with reference to the accompanying drawings.
In the present invention, a PET (polyethylene terephthalate) film or an ASA (Acrylic Styrene Acrylonitrile) film is used as a high-gloss thermoplastic film. The PET film or the ASA film is a thermoplastic synthetic resin film, and has a very high surface hardness and transparency, and has excellent luster because the surface of the surface is smooth. Thus, the PET film or the ASA film has recently been used as a board surface material for furniture panels and the like.
As shown in FIGS. 1 and 2, the method for manufacturing an environmentally friendly high gloss thermoplastic film-coated emboss panel according to the present invention includes a smoothing

1, 3 (b) and 3 (c), the method for manufacturing an environmentally friendly high gloss thermoplastic film-coated emboss panel according to the present invention is characterized in that the high gloss
Unsaturated polyesters are produced by the polycondensation reaction of unsaturated dicarboxylic acids such as maleic acid and fumaric acid with glycols such as ethylene glycol and diethylene glycol, and are cured when cross-linking occurs by polymerization reaction of styrene monomers. Cobalte naphthenate can be added as a catalyst to accelerate the crosslinking reaction of the styrene monomer. When the unsaturated polyester resin (3) is mixed with the styrene monomer in an amount of 25% by weight to 50% by weight based on the total weight of the unsaturated polyester resin (3), the styrene monomer functions as a dilutable curing reaction agent to dilute the unsaturated polyester in a paste state, The unsaturated polyester is fully cured by a cross-linking reaction between 12 hours and 24 hours.
Therefore, in the unsaturated
1 and 4, a method for manufacturing an environmentally friendly high gloss thermoplastic film-coated emboss panel according to the present invention is characterized in that an unsaturated polyester (3) applied to a smooth layer (7a) of a board (1) (3) a semi-curing step of semi-curing at room temperature and normal pressure in the state of being adhered to the substrate (5). The time for reaching semi-curing is preferably from 1/4 to 3/4 of the time for reaching full curing by measuring the time for reaching full curing, but it is not limited thereto. Depending on the amount of the styrene monomer to be blended, it is semi-hardened after about 3 to 12 hours of application to the board. In the semi-cured state, the styrene monomer not participating in the crosslinking reaction remains in the unsaturated polyester (3) coating layer. The present invention is based on the point that the boiling point of the styrene monomer is about 145 캜 which is relatively low.
As shown in FIGS. 1 and 5, the method for manufacturing an environmentally friendly high gloss thermoplastic film-coated emboss panel according to the present invention is characterized in that the surface of the coated layer of the semi-cured unsaturated polyester (3) (3) heat-curing the semi-cured unsaturated polyester (3) coating layer by thermocompression at 145 占 폚 to 200 占 폚 and 5kgf / cm2 to 100kgf / cm2 for 1 second to 180 seconds to obtain a residual styrene monomer (3) from the semi-cured unsaturated polyester And an unsaturated polyester coating layer which emulsifies the embossment of the mirror-
As shown in FIG. 6, in the step of fully curing and embossing the unsaturated polyester coated layer, a three-dimensional embossed shape is formed on the mirror-
