JPH08135140A - Decorative laminated sheet - Google Patents

Abstract

PURPOSE: To provide a decorative laminated sheet with sufficient strength on its surface by laminating a ligneous veneer on both surfaces of a preformed wood board and laminating a facial tissue on one surface side of the laminated ligneous veneer through a resin impregnated paper. CONSTITUTION: A preformed wood board 10 composed of a strand board or the like is used as a heartwood and South-Sea wood veneers 11, 12 are adhered to the front and back of the preformed wood board 10. A resin impregnated paper 13 impregnated with a melamine resin or a phenol resin is adhered to one surface side of the laminated South-Sea wood veneer. A decorative laminate sheet is formed by printing gain patterns on the surface of a thin sheet or a titanium paperes or the like on the surface of the resin impregnated paper 13 and laminating a facial tissue 14 applied with a synthetic resin paint of a urethane resin or a polyester resin or the like on its whole surface. Thus a decorative laminated sheet with surface not easily flawed and color not easily changed can be formed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative board used as a floorboard or wallboard of a building.

[0002]

2. Description of the Related Art Decorative boards used for conventional floorboards, wallboards, etc. are transparent or colored after a veneer is attached to the surface of plywood (for example, 5 plies of Southern Ocean material) and the surface is colored and wiped. It is common to have a structure coated with a transparent synthetic resin paint.

[0003]

However, in the above decorative plate, since the veneer is a natural material, it is difficult to obtain a large quantity of homogeneous products because of different colors and subtle differences in physical properties. There is. In addition, it is difficult to obtain plywood due to restrictions such as deforestation, and it is more expensive. Furthermore, when the decorative board is used as a floor board, it is relatively soft, so that the projection board has a dent on the caster or the like, and when hot carpet or the like is placed on the surface, it shrinks due to heat and cracks occur on the projection board. was there. The present invention has been made in view of the above circumstances, is cheaper than conventional decorative boards, scratches are less likely to occur on the surface,
Further, it is an object of the present invention to provide a decorative plate which is unlikely to cause color difference.

[0004]

A method according to the above-mentioned object.
In the decorative board described above, wood veneers are laminated on both sides of a wood piece molding board, and the decorative paper is laminated on one surface of the laminated wood veneer with resin impregnated paper. Here, the wood piece molding plate is what is generally called a strand board,
Use a piece of wood with a length of 30 to 80 mm, a width of 1/3 or less of the length, and a thickness of 0.4 to 0.6 mm. Mix this with melamine resin, phenol resin, etc. and heat it. It is preferable to use a pressed product. Here, if the wood pieces are aligned in the lengthwise direction and pressed so as to have an orientation, one having a large bending strength in that direction can be obtained. The wood veneer has a thickness of 0.5 to 1.
Use about 5 mm, the lamination of the wood piece molding plate,
It is carried out by bonding with a common adhesive such as vinyl acetate resin or urea resin (the same applies to the following resin-impregnated paper and decorative paper lamination). The resin-impregnated paper laminated on one side of the wood veneer is a paper obtained by impregnating a paper with a melamine resin or a phenol resin and laminating a plurality of the papers at a high pressure.
Decorative paper laminated on the surface of this resin-impregnated paper is thin paper,
It is preferable to use, for example, a titanium paper or the like which has a wood grain pattern printed on its surface and is coated with a synthetic resin paint such as urethane resin or polyester resin on the entire surface.

[0005]

In the decorative board according to the first aspect, since the wood piece molding board is used as the core material, the price is relatively low and the bending strength is constant. However, since the wood piece molding plate has significant unevenness on the surface and is extremely poor in smoothness, a wood veneer is laminated on the front and back surfaces of this wood piece molding plate. This makes the surface uniform. However, the hardness of the surface is not sufficient only by laminating wood veneers. Therefore, resin-impregnated paper is attached to one surface of the wood veneer. Since the resin-impregnated paper is extremely hard, the load from the surface is supported by this, and the depression due to the caster or the like is less likely to occur. Since the appearance is poor only by this, a decorative paper is further laminated on the surface of the resin-impregnated paper to improve the appearance.

[0006]

Embodiments of the present invention will now be described with reference to the accompanying drawings to provide an understanding of the present invention. FIG. 1 is an explanatory view of a decorative board according to an embodiment of the present invention.

As a core material, a wood piece molding plate (OSB) 10 having a thickness of 9.5 mm is used, and South Sea wood veneers 11 and 12 as an example of a wood veneer having a thickness of 1.2 mm are adhered to the front and back thereof. . The resin-impregnated paper 13 described above is bonded to this surface, and the decorative paper (pre-coated paper) 14 is laminated on the surface. In addition,
An adhesive such as the above-mentioned conventional vinyl acetate resin or urea resin is used for these joining.

Since the decorative paper 14 is made by printing, there is no difference in color and the same product can be manufactured in large quantities. Further, the resin-impregnated paper 13 arranged in the lower layer
Since it is hard and receives the load on the surface, there is no dent due to casters or the like. Moreover, even if a hot carpet or the like is placed on it, cracking does not occur.

In the above embodiment, the thickness of the wood piece molding plate is limited, but it is not limited as long as it has a thickness that can be used as a floor plate or a wall plate.

[0010]

In the decorative board according to the first aspect of the present invention, the strength and the dimensional change are not inferior to those of the conventional laminated board using plywood, and are cheaper than the conventional laminated board using plywood. Furthermore, since the decorative board uses decorative paper on the surface and resin-impregnated paper as the lower layer, it does not cause a color difference due to the individual decorative boards, unlike conventional decorative boards. It has surface strength and is less likely to have depressions due to casters, etc.
