Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing an artificial heathered decorative veneer, and its purpose is to provide an artificial heathered decorative veneer that has the luster and unique appearance unique to wood.

Conventionally, artificial heathered decorative veneers are produced by dyeing or bleaching the desired color using an adhesive, or combining raw veneers that have been selected for the number of channel grooves, etc., and laminating and press-bonding them between a pair of templates. However, after forming a veneer laminated flitch, the adhesive layer of the flitch was peeled off to form a wood grain pattern.

As a result, the heathered patterns of the decorative veneers obtained are quite variable, and it has become possible to obtain artificial heathered decorative veneers that look very similar to the heathered patterns of decorative veneers obtained by directly peeling natural wood. .

In the present invention, the appearance of conventional artificial heathered decorative veneers is further varied, and there is a method for obtaining artificial heathered decorative veneers with a luster similar to that of decorative veneers obtained from natural wood and a unique appearance not seen in the past. This was completed after considering the following.

That is, the present invention is an artificial method in which raw veneers are laminated and pressure-bonded between a pair of templates using an adhesive, and after the veneer lamination is made into a flitch, the adhesive layer of the flitch is peeled off so as to form a wood grain pattern. A method for producing an artificial heathered decorative veneer, characterized in that a veneer impregnated with a synthetic resin to make it transparent or translucent and a commonly used veneer are used in appropriate combinations as raw material veneers. Regarding the manufacturing method, the most distinctive feature is that a part of the raw veneer is impregnated with synthetic resin, which gives gloss to a part of the wood grain pattern, and the color of the base layer is changed by impregnating it with synthetic resin. It is possible to change the wood grain pattern by seeing it on the surface through the veneer.

Hereinafter, the present invention will be explained in detail with reference to the drawings. Fig. 1 is a side view showing the process of appropriately laminating a synthetic resin-impregnated veneer and a conventional veneer in the present invention, Fig. 2 shows a decorative veneer obtained by the method of the present invention, and Fig. 3 A cross-sectional view is shown in which the veneer is attached to a substrate to form a decorative board.

First, the raw material veneer used in the present invention has a thickness of 0.2 to 2
．． A veneer (1) for products that has no or very inconspicuous wood grain pattern and has been treated by dyeing it in the desired color, and the veneer is coated with polyester resin, acrylic resin, or A synthetic resin-impregnated S plate (2) is used, which is impregnated with a synthetic resin liquid that makes a veneer of styrene, methyl methacrylate (M, M, A) transparent or translucent.

Next, apply a commonly used wood adhesive such as urethane or epoxy resin to the surfaces of the two types of single sheets (11, (2)) and attach a pair of templates (11, (2) as shown in Figure 1). (A veneer laminated flitch is created by pressing with a pressure of about 10 to 30 kg/- for 3 to 24 hours.) The adhesive can be colored appropriately by mixing dyes or pigments. You can leave it there.

Next, the adhesive layer of the veneer laminated flitch is prepared using a band saw or the like so that it has the desired wood grain pattern, and then the steel surface is scraped with a slicer or the like to a thickness of about 0.2 to 1,000 liters (Qwa). The desired artificial texture decorative veneer (5) as shown in Figure 2 is obtained.

As described above, in the artificial texture decorative veneer (5) obtained by the method of the present invention, transparent or translucent veneers (2) impregnated with synthetic resin are placed at the required positions of the regular veneer +11. The veneer is attached to a substrate (6) such as plywood with a colored adhesive (
7) When pasted through a transparent or translucent veneer, the color of the adhesive may be visible through the transparent or semi-transparent veneer, and the veneer impregnated with synthetic resin has a unique luster and an appearance similar to natural wood. It is possible to obtain an artificially textured veneer with a unique appearance.

Examples will be described below.

A veneer dyed tan with a thickness of 0.61 and a veneer with a thickness of 0.3
10 kg/cn of unsaturated polyester resin colored yellowish brown on III veneer! The raw material veneer is a raw material veneer that is immersed for about 30 minutes under pressure to inject 100% of the liquid agent by weight and then dried, and the entire veneer becomes translucent. Raw material veneer 2 is simply dyed yellowish brown. ~Laminated between a pair of concave and convex mold boards using a dark brown colored water-based vinyl urethane resin adhesive at a ratio of one raw material veneer impregnated with resin for every three boards, and 20K
A veneer laminated flitch was created by pressing under the condition of g/ctl -12 hours. Next, the material was adjusted so that the adhesive layer of the flitch had the desired wood grain pattern, and the surface of the flitch material was then sliced to a thickness of 0.4 fi with a slicer to obtain the desired artificial grain decorative veneer.
