Description

[Detailed description of the invention] The present invention relates to a method for manufacturing artificial wood veneers.

As an example of the prior art of the present invention, the applicant of the present invention
``Method for manufacturing decorative veneers'' (Special application 1973) dated January 14, 2013.
No. 2-3244), but the content of this application is [A flitch is created by laminating and bonding a plurality of at least one type of raw wood veneer with a colored adhesive, and the flitch is sliced to produce sliced veneers. It is characterized by producing a decorative veneer with a wood grain pattern by coloring the veneer surface of the sliced veneer, and its purpose is simply to:
To provide a method for efficiently manufacturing decorative veneers at low cost.

However, the present invention uses a wood veneer with high specific gravity (and thickness) that is difficult to dye, dyes it to a pseudo-target color, and provides an artificial wood veneer that is full of mass. The aim is to contribute to development.

Hereinafter, the present invention will be explained in detail based on the drawings.

In the present invention, a wood veneer 2 having a large thickness, for example, 1 mm to 2 rran, is created by rotary cutting a log 1 having a specific gravity of 0.6 or more.

Next, a colored adhesive 4 containing a phenol resin, urethane resin, vinyl acetate resin, etc. as a main component and mixed with a pigment or dye is applied to one side of the wood veneer 2 using a sprayer 3.

At this time, the coloring should match the color of the pipe of the simulated target wood.

Next, 50 to 10 wooden veneers 2b coated with adhesive 4
0 sheets are laminated and compressed using templates 5, 5 each having a concavo-convex shape corresponding to the inner surface from the 10-1 direction, and the adhesive 4 is solidified to create a flitch 6 with a concave-convex shape which is laminated and integrated.

Next, the flitch 6 is cut into slices so that the adhesive layer 10 has a wood grain pattern and has a thickness of 0.2 mm to 0.41 rI.
A thin piece 7 with a small thickness of fn is made, and the thin piece 7 is immersed in a dyeing solution 8 made by dissolving an acid dye, a metal complex dye, etc. in water to dye it in a pseudo target material color, and then dried. This is an artificial wood veneer 9 obtained by this process.

Incidentally, if the dyeing solution 8 is heated to a boiling state, the stainability of the thin piece 7 will be improved.

As is conventionally known, when dyeing wood, the dye's ability to dye the wood largely depends on the specific gravity and thickness of the wood to be dyed.

For example, when dyeing a wood veneer with a thickness of 1 mm by boiling, the specific gravity must be 0.6 or less when using an acid dye, or 0.4 or less when using a metal complex dye, or sufficient dyeing will not be possible. Can not.

However, artificial wood veneers, which are made by processing low-value wood to imitate wood veneers obtained from high-value wood, must have specific gravity in order to express the sense of mass in addition to color. It must be made using wood with a density of 0.4 to 0.6 or more, and in this case, the wood veneer obtained from wood with a high specific gravity usually needs to have a thickness of 1 m++ or more, and the grain of the artificial wood veneer is formed. As mentioned above, it was extremely difficult to dye.

According to the present invention, artificial wood veneers have good dyeability due to their small thickness, while artificial wood veneers have good dyeability due to their high specific gravity and thickness, and artificial wood veneers are dyed in a pseudo target color. This artificial wood veneer has the effect of being easily and easily obtained, and in addition to its color, this artificial wood veneer also has a sense of mass that could not be obtained with conventional manufacturing methods.
