Description

The present invention relates to a decorative board and a method for producing the same.

[Problems to be Solved by Conventional Techniques and Inventions]

Generally, the decorative board includes veneer overlay plywood, plastic overlay plywood, paper overlay plywood, cloth overlay plywood, hard board overlay plywood, etc.
Veneer overlay plywood means ordinary plywood (those that are laminated only but not subjected to secondary processing) have a beautiful grain of natural wood, or a thin decorative veneer cut from name wood. The plastic overlay plywood is obtained by coating the surface of the plywood with a synthetic resin film, synthetic paper or a plastic laminate. The paper overlay plywood is an overlay of pattern paper, and the cloth overlay plywood is an overlay of cloth.

Therefore, the surface of the decorative plate as described above is flat and does not give a high-grade feeling. Further, if an uneven surface is to be formed on these decorative plates, it is necessary to provide an uneven part on the front surface of the substrate and coat a thin decorative veneer on it, which is troublesome to manufacture and In order to correspond to the concave and convex portions of the concave and convex portions, the thickness of the entire substrate must be increased, which results in a large amount of wasted material, which leads to high cost, and a large weight, which is troublesome to carry.

Therefore, it is an object of the present invention to provide a decorative plate that can be manufactured easily and at low cost and can manufacture a door having a window portion, and a manufacturing method thereof.

[Means for Solving the Problems]

In order to achieve the above object, the decorative plate according to the present invention,
A flat plate body on which a backing member is partially stretched and through holes are provided; and a film-like body that is in close contact with the front surface of the substrate and the inner surface of the through hole. is there.
In addition, the method for manufacturing a decorative board according to the present invention is a method in which a backing member having air permeability is partially bonded to a back surface of a flat plate body, and then a through hole is formed to form a substrate. To
The front side of the substrate is covered with a preheated thermoplastic film body, and the film side body is suctioned to the front side.
Alternatively, after coating the front surface with a thermoplastic film body which is not heated, the film body is heated and the film body is sucked toward the front side to form the film body. The front surface and the inner surface of the through hole are brought into close contact with each other, and then the opening-corresponding portion of the film-like body which covers the rear surface side opening of the through hole is cut and removed.

[Work]

Since the decorative plate according to the present invention has the front surface of the substrate and the inner surface of the through hole covered with the film-like body, the front surface of the decorative plate can be formed without using the flat plate member and the abutting member as a high-grade material. The whole can be a high-grade decorative surface. Moreover, the window is formed by the through hole whose inner surface is covered with the film-shaped body. Further, if the through hole is formed in the contact member, the depth of the window portion becomes large, giving a luxurious feeling as a whole.

Further, according to the method for manufacturing a decorative plate according to the present invention, since the flat plate member and the pad member are both breathable,
The film-like body is easily and surely adsorbed and adhered to the substrate. Furthermore, for the substrate, the pad member is attached to the flat plate,
Since it is sufficient to form the through hole, the substrate can be easily manufactured.
