Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a method for manufacturing an artificial decorative veneer with a wood grain pattern obtained by subjecting the material to IIK processing, and its purpose is We aim to contribute to the development of this industry by providing a widely available method for easily producing artificial decorative veneers with a unique striped pattern that closely resembles knots.

Conventionally, this type of artificial decorative veneer is produced by dyeing or decolorizing a large number of material veneers as necessary, then laminating them with adhesive, and creating unevenness on the inner surface from the top and bottom. It was a general-purpose technique to obtain the flitch by pressing it with a pair of presses, curing the adhesive, and forming an irregularly shaped flitch, and then slicing the flitch. However, as mentioned above, Artificial decorative veneers obtained by conventional manufacturing methods have extremely monotonous wood grain patterns, do not exhibit the knots that natural wood has, and have the disadvantage that they cannot be said to closely resemble natural wood. (90) The present invention has been made for the purpose of eliminating the above-mentioned drawbacks of the conventional artificially decorative veneer.Hereinafter, the method for manufacturing the artificially decorative veneer of the present invention will be explained as shown in Fig. 1. The present invention will be explained in detail based on the embodiment shown in FIG. l Create a large number of veneers (1) of materials ranging from s/m to g, os/m. Next, the material veneer (1) is
Either by dipping it in a dyeing solution or by printing it, the color will be approximately the same as the desired color of natural wood. In this case, in order to dye the material more effectively and uniformly, the material veneer (1) may be subjected to bleaching and degreasing treatments in advance.

Next, the material veneer (1) is adjusted to an appropriate moisture content, and then laminated with adhesive such as urethane resin adhesive, phenol resin adhesive, area resin adhesive, etc. The adhesive is then hardened to form a laminate (3) by pressing with a pair of presses (2) +2) each having a male and female unevenness on its inner surface. Next, use a drill or other jig to drill an arbitrary part of the laminate (3), preferably in the same direction as the stacking direction of the raw material veneer (1), to a diameter of y3 m/#l to ! Q I
Drill a circular or armature hole (4) of II/1111. Next, the long rotary veneer (5) with a saturated moisture content of 200% to 230% is softened by irradiation with microwaves (for example, frequency 154 GHz, output 2 KW). resin adhesive,
Adhesives such as phenolic resin adhesive, area resin adhesive, etc. from 1 (11) f/vl to 150'l/FFI, desired 1
In other words, after applying the coating at a coating amount of 121/m2, roll it up with the direction perpendicular to the direction of the wood fibers as the base axis so that no gaps are created, and the shape is approximately the same as the shape of the hole (4) provided in the laminate (3). Create a wrapping (#I). Next, the laminate (3
), the shell wrapping material (6) is pressed into the hole (4) provided in the flitch (
7). Then the flitch (7) was heated to 0.2 v.
r/solution to 1. By slicing the material into thin pieces of 0m/#, an artificial decorative veneer (8) with a wood grain pattern including streaks can be obtained.

Incidentally, as the wrapping material (6) used in the present invention, the eighth
As shown in the figure, a long rotary veneer (5) may be rolled up with the axis parallel to the wood fiber direction, but in this case, when slicing the flitch (7), Moreover, the wood fibers of the wrapping material (6) are cut at right angles, resulting in an extremely poor slicability.

In addition, in the above embodiment, when making the wrapping (6), the long rotary veneer (5) was placed in a micro liquid to undergo a softening treatment, but other softening treatment methods may be used. There are methods such as immersion in an ammonia solution or boiling.

The artificial decorative veneer of the present invention is obtained as described above, and according to the present invention, it has the effect that an artificial striped pattern can be obtained extremely easily.In particular, the wrapping used in the present invention If a long rotary veneer is softened while maintaining a saturated moisture content when manufacturing a product, it will be easier to press the winding material into the holes in the laminate, and the winding material will be It has the effect of filling the hole with no gaps.
