JPS59215850A - Preparation of artificial grained veneer - Google Patents

Abstract

PURPOSE:To develop an artificial grain at a low cost by scattering colored chips through a screen drilled patterned after a grain. CONSTITUTION:A screen 2 drilled 3 patterned after a grain is placed on a plate body 1 made in a layer and colored chips 4 are scattered thereon from above. Finally, the chips are pressed by heat to be finished in a plate. An artificial grained veneer can be massproduced economically.

Description

[Detailed Description of the Invention] [Technical Field] This invention belongs to the field of technology for reproducing veneers with artificial wood grain using wood-based materials. [Background Art] Traditionally, wood-based materials have been used. Attempts to artificially reproduce and use wood grain are being carried out on an industrial scale. In most methods, relatively low-grade wood veneers are manufactured from logs using rotary lace, etc., which are laminated with an adhesive interposed, and then sandwiched between molds and pressed together to obtain a flitch. hand,
Next, a technique was used to slice this to express the desired wood grain.

The above methods are suitable for faithfully expressing the intricate wood grain of natural wood, but the process is complicated and it is not necessarily suitable for expressing general wood grain. .

On the other hand, a method of obtaining wood chips (hereinafter referred to as "chips") obtained by coarsely crushing low-grade logs and using these to regenerate wood boards is conventionally known.

This method involves the steps of mixing the chips and an adhesive, cutting the chips into layers, and pressing them under heat to obtain a plate.

Conventionally, in the above-mentioned method of manufacturing chipboard, the original color of the material was used, and instead of being used as a decorative board, it was usually used as a plywood to which a decorative board was attached. It is only natural that the above-mentioned manufacturing method would not be able to express wood grain, and the use of this as a decorative board had never been considered.

[Purpose of the invention] This invention was made in view of the above circumstances, and by devising a process suitable for mass production,
The purpose was to provide a method for inexpensive reproduction.

[Disclosure of the Invention] In this invention, chips obtained by crushing wood raw materials are colored, or chips and a coloring agent are mixed to obtain a predetermined color to prepare a plurality of colored chips, and then the wood grain is adjusted. The method is characterized in that the chips are arranged in the shape of a handle, and then a plate is manufactured.

In other words, first prepare a low-grade log and crush it. The pulverization step for crushing can be carried out using ordinary equipment. Grind the chips to the same size. Use a sieve etc. for this. Next, color the chips. The chips are colored by dyeing the chips or by mixing the chips with a coloring agent. The colorant may be any dye, pigment, or the like.

The chips are made into layers to express the desired wood grain pattern. In this case, normal board making equipment is used, but in order to express the wood grain pattern, As shown, for example, a primary plate 1 made into layers
On top of this, color chips 4 are further sprinkled in a wood grain pattern. At this time, colored chips 4 are spread through a screen 2 having perforations 3 in a wood grain pattern. Then, it is heated and pressed to form a plate.

Note that there is no need to heat press the next plate. Of course, it may be heated and pressed. Furthermore, the screen may be used to express the wood grain and form the paper in layers without passing through the next board. After this, it is dried or moistened as appropriate, the surface is finished, and the product is cut into a predetermined size.

[Effects of the Invention] This invention is characterized in that the so-called chipboard manufacturing method includes a step of distributing colored chips in a wood grain pattern. Since it can be expressed economically, it has the effect that artificial wood veneers can be mass-produced economically.
