Description

[Detailed Description of the Invention] [Technical Field] The present invention involves coating the surface of a wooden veneer with dye, then scattering pieces of insulation material on the wooden veneer, and then laminating several wooden veneers. After applying steaming treatment and dyeing the wooden veneer, the wooden veneer is laminated and integrated through eight bonding agents, and then cut to produce a decorative copper plate. .

[back]; (technique 11ij) subordinate, i=, this kind of artificial makeup 4. The treatment is wood 3. It was a widely known and publicly used technique to stack wooden veneers together using an adhesive, press them together, and then cut them into thin strips. However, in the above-mentioned manufacturing method using the flame-burning technology, the dyeing is applied almost uniformly to the wood veneer, so the changes in the wood grain and internal shape of the resulting artificially decorated veneer are monotonous and natural. Natural wood veneers obtained from trees are far superior to natural wood veneers, and they have drawbacks that cannot be compared to natural wood veneers.

[Purpose of the invention]

The present invention provides a manufacturing method for easily obtaining artificial decorative veneers having extremely natural-looking wood patterns and changes in color B1, which eliminates all of the drawbacks of the conventional manufacturing methods described above, and thereby contributes to the industry. The aim is to contribute to the development of

[Tachibana Sei of invention]

Hereinafter, the method for producing an artificially decorated veneer according to the present invention will be explained in detail based on the embodiments shown in FIGS. 1 to 7.

This invention Q1 Wood veneer (1) with a thickness of 0.2% to 2.0% is obtained by rotary cutting or slicing raw wood such as Agatis spp., white serayas spp., or Depakizuki. create. If necessary, the wood veneer is subjected to pretreatment such as decolorization and hot water washing, and then dyeing solution (2
) on the entire surface. The dyeing solution (2) can be applied by using a roll kneader, spray, brush, or immersion in the dyeing solution.

Next, heat insulating material pieces (3) made of extruded rubber, polypropylene foam, etc. are scattered on the surface of the wood veneer (2), and then a plurality of wood veneers (1) are laminated, and then a steam cauldron ( 4) The wood veneer fi+ is dyed by putting it inside and subjecting it to steam heating, that is, steaming treatment, to dye the wood veneer fi+.

The steaming treatment conditions are a temperature of 80°C to 10°C.
0°0% humidity 80% to 10% (l q6, time 2 to 5 hours is suitable. Of course, depending on the target tree species, the above steaming treatment conditions may be changed widely. The wood veneer (1) is finished in a light color in the area where the insulation strip (3) is located, and the wood veneer (1) is finished in a light color.
1) Overall, the Q′i color unevenness was j1 tie [, and the staining was dull. A large number of such wood veneers (1) are pressed together with adhesive using a pair of presses from the direction of 1, Variation 3f: Make the i-cut 11 times to create 7 riches (6) with an uneven shape.Of course, the shape of the flitch (6) may be square.Next, the 7 riches (6) are sliced. By cutting, an artificial decorative veneer (7) having a wood grain pattern (, Y) with a thickness of 0.2% to 2.0% is obtained.

〔Effect of the invention〕

The method for manufacturing the artificially decorated veneer of the present invention is as described above (14).
3 is extremely simple and can be done with less dyeing solution, and the unevenness of dyeing is moderate. Artificial decorative veneer with 1+ has the effect of making both the wood grain pattern and color extremely natural.
