Description

[Detailed description of the invention] [Technical field] A wooden veneer is impregnated with a synthetic resin to make it transparent or semi-transparent.
In addition to adding brightness, it also ``directs'' the wood grain pattern.
=lA'1ill'c, or it relates to a decorative board manufacturing technique +lV obtained by pasting the wood veneer on a substrate on which a printed paper with a wood grain pattern is pasted.

[Background technique? , If :) Conventionally, decorative boards made by pasting a wooden veneer impregnated with a synthetic resin onto a substrate such as plywood, insulation board, or chipboard are made by impregnating a wooden veneer with a synthetic resin. Therefore, transparency or translucency was imparted to the substrate, and as a result, the surface of the substrate could be seen through the wooden veneer.

Therefore, it has been widely proposed to color the surface of the board to hide the color of the board, but this has the problem of increasing the number of steps required to hide the board color.

[Purpose of the invention]

Originally, the wood grain pattern was unclear and the color was monotonous, so we used a wood veneer that was unsuitable for cosmetic use, and the wood grain pattern was clear and the color was complex, giving it a wood feel. The purpose of this invention is to provide society at large with a manufacturing method for easily producing decorative laminates that are smooth and have high surface hardness, thereby contributing to the development of this industry.

[Structure of the invention]

The present invention can be applied to logs such as agathis wood, Lapla wood, white seraya wood, and Aius wood, which have a dull grain pattern and a monotonous color, or wood such as Japanese pine wood, Japanese pine wood, etc., which have a clear grain pattern but a dull color. rotary cutting or nullais cutting of raw wood,
A wood veneer (1) with a thickness of 0.2% to 0.5% cut to a predetermined size is treated as necessary by degreasing, bleaching, hot water washing, etc., and then treated with polynisdel resin liquid and polyethylene. Vn1 is soaked in other synthetic resin solution (2) to impregnate the wood veneer (with an internal ratio of 11, synthetic resin). It is preferable to carry out the process under reduced pressure or pressurized conditions in order to easily show the impregnation into the wood veneer (1).In this way, the internal ratio of the wood veneer (1) is sufficiently impregnated with the synthetic resin, and the wood veneer (1) It imparts transparency or translucency to the synthetic resin.A small amount of coloring agent may be added to the synthetic resin.On the other hand, on the surface of the substrate (8) such as plywood, chipboard, particle board, insulation board, etc. A decorative layer (4) is completely formed by directly printing a desired wood grain pattern or pasting a printed paper with a wood grain pattern, and a wooden veneer (4) impregnated with a synthetic resin is formed on the surface of the substrate (8).
This is a decorative board (5) obtained by placing the wood veneer (1) and the substrate (8) together by placing and heat-pressing the wood veneer (1).

In the above example, the synthetic resin impregnated in the wooden veneer (1) was attached to the substrate +8), but transparent vinegar was used between the wooden veneer +11 and the substrate (3). It is desirable to use an adhesive such as a vinyl resin adhesive, a phenol resin adhesive, or a urea resin adhesive in order to make the bonding and integration even stronger.

〔Effect of the invention〕

The manufacturing method of the decorative board of the present invention is underdeveloped as described above, and the decorative board obtained by the manufacturing method of the present invention uses wood veneer with unclear grain pattern or monotonous color. The effect is that the wood-4 appearance is clear and the colors overflow with the deep wood texture.

Claims (1)

[Claims] 1) A wooden veneer is impregnated with a synthetic resin to give it transparency or translucency, and a wood grain pattern is directly printed on it, or the wood veneer is pasted on a substrate with a wood grain pattern printed on it. A method for manufacturing a decorative board characterized by pasting.
