Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a laminate decorative board having the texture of natural precious wood and a method for manufacturing the same.
A transparent resin film 2 with scratches 1 in the longitudinal direction spaced apart in the width direction on the surface 2 The metal coloring layer 3 side on the back side is attached to the substrate 4
The specified invention is a laminated decorative board characterized in that the surface resin layer 6 is adhered to the surface side of the transparent resin film 2 on which the pattern printing layer 5 is provided, and Metallic colored ink is printed over almost the entire surface, and then scratches 1 are made in the longitudinal direction on the surface of the transparent resin film 2.
After spaced across the width direction, a woodgrain pattern is printed on the surface of the transparent resin film 2, and the transparent resin film 2 is
The combined invention is a method for manufacturing a laminated decorative board characterized by applying a surface resin paint to the surface of the transparent resin film 2 after bonding the back surface of the transparent resin film 2 to the substrate 4.

Conventionally, in order to give a decorative board the gloss, shine, and depth of color that natural precious wood has, printing ink mixed with metal powder was printed on the decorative sheet that was attached to the substrate, or Yugashiro and Lauan plywood were used. However, it was not possible to obtain the natural luster of precious natural wood.

In particular, natural precious wood has cellulose arranged uniformly in the longitudinal direction (longitudinal direction), and it has not been possible to reproduce this arrangement of cellulose using printing ink or printing methods. The present invention has been made in view of the above points, and the object of the specific invention is to provide scratches in the longitudinal direction on the surface of a transparent resin film at intervals in the width direction, thereby making it look like natural precious wood. The purpose of this combined invention is to provide a laminated decorative board that provides a surface with a textured texture and a textured surface, and that also has a metal coloring layer on the back side of a transparent resin film that reflects diffusely due to scratches, resulting in a surface that is close to that of natural precious wood. The object of the present invention is to provide a method for manufacturing a laminated decorative board that can easily produce a laminated decorative board having the above-mentioned advantages.

The present invention will be explained in detail below. The surface of a transparent resin film 2 made of synthetic resin such as vinyl chloride, acrylic, polyethylene, polypropylene, or vinyl resin has multiple scratches 1 extending in the longitudinal direction (vertical direction) at regular intervals across the width. The surface of the transparent resin film 2 is finely uneven with scratches 1, and the back surface of the transparent resin film 2 is provided with a metallic coloring layer 3 having a metallic luster over almost the entire surface. . A woodgrain pattern printing layer 5 is provided on the surface of the transparent resin film 2 having the scratches 1, and an adhesive layer 7 is applied to the metallic colored layer 3 side on the back side of the transparent resin film 2, which is attached to plywood or hardwood. It is attached to a substrate 4 such as a board, chipboard, slate, etc., and a transparent surface resin layer 6 made of aminoalkyd, urethane, acrylic, vinyl resin, etc. is attached to the surface side of the transparent resin film 2 attached to the substrate 4.
A decorative laminate board is formed by applying the above.

However, in the laminated decorative board having such a structure, scratches 1 extending in the longitudinal direction are provided on the surface of the transparent resin film 2 at regular intervals in the width direction. It has an appearance similar to that of natural wood, and the surface has the texture and texture of natural wood. In addition, the luster of the metal coloring layer 3 provided on the back side of the transparent resin film 2 is diffusely reflected by the scratches 1, and the woodgrain pattern printing layer 5 shines due to the diffused reflection of the metal coloring layer 3, resulting in a shank similar to that of natural precious wood. . The scratches 1 may be made on the transparent resin film 2 at any time before the surface resin layer 6 is applied to the surface of the transparent resin film 2, for example, before the transparent resin film 2 is pasted on the substrate 4. It may be before or after or before or after providing the metal coloring layer 3 on the transparent resin film 2. Next, the manufacturing method of the laminated decorative board will be explained in detail. First, on the back side of a transparent resin film 2 made of synthetic resin such as vinyl chloride, acrylic, polyethylene, polypropylene, or vinyl resin, there is a metallic colored surface such as mica powder, aluminum powder, copper powder, or brass powder. The back side of the transparent resin film 2 is coated with a metal coloring layer 3 by printing a metallic coloring ink containing the same over almost the entire surface, and then the surface of the transparent resin film 2 is coated with a wire brushing roll or the like in the longitudinal direction. After providing a plurality of scratches 1 at regular intervals across the width, a pattern printing layer 5 is provided by printing a woodgrain pattern on the surface of a transparent resin film 2. Next, the metal coloring layer 3 on the back side of the transparent resin film 2 and the plywood,
After bonding the upper surface of a substrate 4 such as a hardboard, chipboard, or slate with an adhesive such as ethylene monovinyl acetate, a surface resin such as aminoalkyd, urethane, acrylic, or vinyl resin is applied to the front side of the transparent resin film 2. The surface side of the transparent resin film 2 is coated with a transparent surface resin layer 6 by applying a paint over almost the entire surface to obtain a laminated decorative board. Since the present invention has the above-described configuration, in the case of the laminated decorative board of the specified invention, scratches in the longitudinal direction are spaced apart in the width direction on the surface of the transparent resin film, thereby creating unevenness similar to that of natural precious wood. The combined invention achieves the above-mentioned advantages by providing a surface with a pleasant texture and texture, and by reflecting diffusely due to scratches caused by the metal coloring layer on the back of the transparent resin film, it is possible to obtain a surface close to that of natural precious wood. It is possible to provide a manufacturing method that can easily manufacture a laminated decorative board having the following.

The present invention will be specifically explained below using examples. Example 1 A metal coloring layer was provided on the back side of a transparent vinyl chloride sheet having a thickness of 70 μm by solid printing on the entire surface with a metal coloring ink containing 3% mica powder.

Thereafter, a plurality of scratches were applied to the sheet surface in the longitudinal direction using a wire brushing roll, and then a cheek pattern was printed on the surface. The pattern sheet obtained above was laminated onto 4.0~ plywood using an ethylene monovinyl acetate adhesive. Furthermore, apply vinyl modified urethane resin to the surface of the pattern sheet using a roll coater for 5f/2.
The coating was applied and dried to obtain a laminate decorative board. This laminated decorative board had a gloss and texture close to that of natural precious wood.
