Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing artificially decorated veneers.

Artificial decorative veneers are produced by, for example, dyeing wood veneers, laminating them with adhesive, pressing them using a textured plate to form deformed fritches, and slicing them in appropriate directions. can be manufactured.

. In the artificial decorative veneer obtained in this way, the adhesive layer appears as a curved wood grain pattern, giving it the appearance of a natural precious wood. It is widely practiced. However, artificial parking was obtained in this way.

In boards, the growth rings of artificial wood grain appear almost uniformly as shown in Figure 1, so the appearance is completely different from the grain of natural wood, where the growth rings appear unevenly as shown in Figure 2. Therefore, it was not possible to faithfully reproduce the grain-like pattern of natural precious wood. Therefore, an object of the present invention is to provide a method for manufacturing an artificial decorative veneer that can make the width of the growth ring part of the artificial wood grain appear non-uniform like that of a natural precious wood.

The features of this invention will be explained based on FIGS. 3 and 4.

That is, this method for manufacturing artificially decorated veneer is based on the material veneer 1.
are laminated on the uneven plate 3 through a sheet 2 of non-uniform thickness made of a material with good dyeability, pressed and glued to form a deformed frit, and this frit is sliced as shown in Fig. 4. A sliced veneer 4 having a thickness of 0.2 to 0.3 nm is formed, and then the sliced veneer 4 is dyed. As the sheet 2, a urethane sheet or a nylon sheet that can be dyed in a short time is used, and the thickness thereof is 0.03 to 0.5 wLI, and the sheet 2 has a large variation in thickness and lacks uniformity. By using this, the change in the width of the annual ring portion appearing on the surface of the sliced veneer 4 shown in FIG. 5 becomes noticeable.

According to this method, by appropriately changing the thickness of the interposed sheet 2 when laminating the raw material veneers 1, the width of the annual ring portion appearing on the surface of the sliced veneer 4 can be freely changed, and When the thickness of the sheet 2 is varied for each layer, it is easy to artificially reproduce patterns unique to natural wood grain, such as differences in the width of tree rings due to differences in climate from year to year. Furthermore, since staining is performed on each sliced veneer 4 after slicing the fritchi, 1
Since it is possible to dye the sliced veneer 4 formed from one frit in various ways, it is possible to easily produce a wide variety of products using small rods according to the demands of customers.

As described above, the method for manufacturing artificially decorated veneer of this invention is as follows:
The method is characterized by laminating, gluing, and pressing material veneers through sheets of uneven thickness made of well-dyed materials to create deformed fritches, and slicing these fritchis. It has the effect of making the width extremely easy to make uneven and resemble natural precious wood.

Example 1 0.8U1 thickness and 1.2m7! Single sheets of Shelton material having a thickness of L were laminated and cured using an adhesive with a nylon sheet having a thickness of 0.05 to 0.111 interposed therebetween, and a fritchie was formed.

The nylon sheet used had a non-uniform and variable thickness. Slice this Fritsuchi and get 0.22
m! A thick sliced veneer was obtained. This sliced veneer was dyed with dyes: Ranaf Asto Yellow GL Extra Conc (manufactured by Mitsui Toatsu Chemical Co., Ltd.)...0.05q1), Ranil Brown GR (manufactured by Sumitomo Chemical Co., Ltd.)...0.02 (F6, temperature It was dyed at 95° C. for 30 minutes and at a bath ratio of 80. The resulting artificially decorated veneer had a wide variation in the width of the annual rings and a pattern similar to the grain of natural precious wood.

Example 2 A veneer made of agathis material with a thickness of 1.01m and 1.5mw is 0.21! A urethane sheet with a non-uniform thickness of 1 average thickness was interposed, and a urethane adhesive was used to laminate and cure to form a fritchie.

This fritsch was sliced to obtain a sliced veneer with a thickness of 0.257 f1m. Dye: Lana Fast Brown BL (manufactured by Mitsui Toatsu Chemical Co., Ltd.)...0.3%
, Ranil Brown RR Extra Conc (manufactured by Sumitomo Chemical Co., Ltd.)...0.05q1), Ranil Brown MR (manufactured by Sumitomo Chemical Co., Ltd.)...0.05%, temperature 95°C, time 1 hour, bath ratio 70 conditions It was stained with The obtained artificially decorated veneer had the same performance as Example 1.
