In the wood decorative board according to the present invention, a transparent polyester film 1 and a decorative film 2 on which a decorative print has been applied are bonded together via a dry laminating adhesive, and the wood board 3 is arranged so that the polyester film 1 is on the front side. It is characterized in that it is attached to the surface via a heat sealing layer 5 of a thermoplastic resin adhesive film. Further, the method for manufacturing a wood decorative board according to the present invention includes layering a transparent polyester film 1, a decorative film 2 with a decorative print, and a thermoplastic resin adhesive film 4 in this order via a dry laminating adhesive. This composite film 6 is placed on the surface of the wooden board 3 with the polyester film 1 facing up, and heated and pressurized to bond the thermoplastic resin adhesive film 4 to the wooden board 3. 1 and a decorative film 2 are attached to each other. The present invention will be explained in detail below. As the polyester film 1, a polyethylene terephthalate film can be used, and as the decorative film 2, a polyvinyl chloride or polypropylene film with a wood grain pattern etc. printed on the back side can be used. polyester film 1
is formed to be colorless or colored transparent, and the polyester film 1 and the decorative film 2 are adhered to each other using a dry laminating adhesive, and the thermoplastic resin adhesive film 4 is further adhered to the decorative film 2 using a dry laminating adhesive. Possibly a polyester film 1, a decorative film 2,
A composite film 6 having a three-layer structure of adhesive film 4 can be obtained. As the thermoplastic resin adhesive film 4, it is preferable to use a polyolefin whose melting temperature is lower than that of the polyester film 1, and which is copolymerized with a polar monomer to improve adhesiveness. That is, this product is a product obtained by grafting or copolymerizing a polyolefin such as polyethylene or polypropylene with a monomer having a carboxyl group as a polar group such as maleic acid, fumaric acid, acrylic acid, or methacrylic acid.
Typical examples include EAA (ethylene/acrylic acid), EMA (ethylene/methacrylic acid), EEA (erylene/acrylic ester), and ionomer (ethylene/acrylate). This product is provided as an adhesive polyolefin resin by Mitsubishi Yuka's "Modeitsuku", Mitsui Petrochemical's "Admer", Sumitomo Chemical's "Bond First", Toa Fuel Chemical's "HA series", Exxon's "Dexon", etc. This can be used by forming it into a film. Furthermore, before forming the composite film 6 as described above, it is preferable to subject each film 1, 2, and 4 to a corona discharge treatment. As shown in FIG. 5, the corona discharge treatment is performed by applying high frequency and high voltage between the insulated electrode 15 connected to the transformer 20 of the corona discharge treatment machine 14 and the grounded dielectric roll 16. dielectric breakdown and generate corona discharge,
This can be done by passing the films 1, 2, 4 through this corona discharge. By polarizing and activating the adhesive, adhesive performance can be improved. Film 1 treated with corona discharge in this way,
Films 1, 2, and 2 are coated with adhesive for dry lamination on one or both of the opposing surfaces of films 2 and 4.
A composite film 6 can be obtained by stacking films 1, 2, and 4 and integrating them by stacking films 1, 2, and 4 and passing them between rolls.
Here, as the adhesive for dry lamination, it is preferable to use an Utarene type adhesive in view of properties such as heat resistance, and A-
367/A-7, A-371/A-3, A-375/A-
3, A-310/A-3 (all product numbers), etc. can be used. In applying the composite film 6 to the surface of the wooden board 3, the composite film 6 is placed on the wooden board 3 so that the polyester film 1 is on the front side, and then heated as shown in FIG. roll 1
By passing the adhesive film 4 between 2 and 12,
The adhesive film 4 is fused to the wooden board 3 by heating and pressurizing it under conditions higher than the melting temperature of the polyester film 1 and lower than the melting temperature of the polyester film 1. In this way, a wooden decorative board as shown in FIG. 3 is obtained, in which the polyester film 1 and the decorative film 2 are attached to the surface of the wooden board 3 via the heat-sealing layer 5 of the adhesive film 4.

The invention will now be illustrated by examples. Example A transparent polyester film (biaxially oriented polyethylene terephthalate film: product emblem, manufactured by Unitika Co., Ltd.) with a thickness of 25 μm was subjected to corona discharge treatment under conditions of 40 dyne/cm using a corona discharge treatment machine, and a wood grain pattern was applied to the back side. A decorative film made of polyvinyl chloride film with a thickness of 70 μm printed with the above-mentioned polyvinyl chloride film and a 40 μm thick adhesive film made of polyethylene (Bond First, manufactured by Sumitomo Chemical Co., Ltd.) prepared by copolymerizing acid anhydride using the high-pressure method were similarly applied. Corona discharge treated. Next, a heat-resistant polyester type urethane adhesive for dry lamination (A made by Takeda Pharmaceutical Co., Ltd.) was applied to the polyester film and the adhesive film, respectively.
-310/A-3) at a coating amount of 5 g/ m2 ,
It was dried by passing it through a dryer at 60 to 70°C. Thereafter, a polyester film, a decorative film, and an adhesive film were layered and passed between rolls to obtain a composite film in which the three were bonded together. The composite film thus obtained was layered on the surface of plywood formed by laminating five 2.4 mm thick veneers with urea melamine adhesive, and then rolled between hot rolls heated to 140°C at 10 m/min. By passing the plywood through the wood at a feed rate of , a decorative wood board with a composite film attached to the surface of the plywood was obtained. Comparative Example A vinyl acetate emulsion adhesive was applied to the surface of the same plywood as in the example at a coating amount of 150 g/ m2 ,
A 70 μm thick polyvinyl chloride film with a wood grain pattern printed on the back was layered on top of this and passed between rolls heated to 60°C to obtain a wood decorative board with the polyvinyl chloride film attached to plywood. Regarding the wooden decorative boards obtained in the above Examples and Comparative Examples, the peel strength between the plywood and the film attached to the plywood was measured, and the surface hardness was also measured. The results are shown in the table below.

As mentioned above, in the case of the wood decorative board according to the present invention, since the polyester film is adhered to the front side of the decorative film, the excellent heat resistance of the polyester film (softening temperature is about 240°C) makes the surface In addition to improving heat resistance, the excellent high hardness of polyester film can increase surface hardness, and polyester film and decorative film can be used as a heat-sealing layer of thermoplastic resin adhesive film. Therefore, since it is attached to a wooden board, the decorative film can be attached to the wooden board with high adhesive strength, and defects such as the decorative film peeling off from the wooden board during bending can be reduced. In addition, in the method of manufacturing a wood decorative board according to the present invention, a composite film composed of a polyester film, a decorative film, and a thermoplastic resin adhesive film is stacked on a wood board, and this is heated and pressurized to bond the thermoplastic resin. Since the polyester film and the decorative film are attached to the wooden board using the heat-adhesive layer of the film, the polyester film and the decorative film can be attached using a dry method without the need to apply adhesive to the wooden board. It is possible,
A wooden decorative board can be manufactured without warping of the wooden board.
