Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an artificial precious wood, and more specifically to a method for producing artificial precious wood in which the cut surface in the thickness direction of a laminate is the surface, and its main purpose is to produce high-quality natural precious wood. To provide a method for manufacturing artificial precious wood, which can produce a natural "shine" and give an appearance close to natural wood by adding color shading to the surface.

In the past, when manufacturing this type of artificial precious wood, "teri"
To create this, a method of combining different types of veneers has been adopted, but this method has the problem that it is difficult to select and combine veneers, making it difficult to create the desired "shine".

The present invention has been made in view of the above points, and will be described in detail below based on embodiments shown in the drawings.

The rotary veneer 1 is not particularly limited and may be made of ordinary South Sea hardwood, and a synthetic resin film 2 with a thickness of 10 to 200 μ, preferably 20 to 100 μ is coated on a part of its surface as shown in FIG. Attach with adhesive.

The synthetic resin film 2 is made of polyamide resin, urethane resin, polyester resin, etc., and its thickness is set to 200μ or less in order to obtain uniform adhesive pressure when stacking and pressing the veneers 1 and to prevent adhesion failure. It is said that

Further, as the adhesive, since the rotary veneer 1 has a high moisture content, a urethane adhesive is used.

After the veneer 1 with the synthetic resin film 2 attached to a part of its surface is dyed with an appropriate dye,
As shown in FIG. 2, a plurality of sheets are superimposed and bonded to form a laminated substrate 3, and then this laminated substrate 3 is cut in the thickness direction along the X-X line or the Y-Y line shown in FIG. In this way, an artificial precious wood with the synthetic resin film 2 appearing on the cut surface is obtained.

In the above dyeing process, the synthetic resin film 2 is dyed more vividly than the rotary veneer 1 due to its good dyeing properties, and as shown in FIG. Since B is dyed less than other parts A, it is dyed lighter than other parts A, so a shading pattern similar to natural wood is formed, and the light colored part B makes the color of the synthetic resin film 2 stronger. By expressing this, the ``shininess'' of natural wood is created on the surface, making it possible to create an appearance that is even closer to that of natural wood.

In addition, by changing the cutting angle in the thickness direction of the laminated substrate 3,
The surface can be formed into a simple straight grain or wide straight grain style, and the rotary veneer 1 can be used for example 1.0 m.
The synthetic resin film 2 also has different thicknesses such as 30μ and 80μ, and widths of 5m/m, 10m/m, and 30ψ.
If a material different from the above is used, in addition to the above-mentioned effect, the pattern will be even more uneven, resulting in an appearance that is even closer to natural wood.
