Description

[Detailed Description of the Invention] The present invention is to develop a manufacturing method for artificially decorated veneers obtained by gluing various treatments to wood veneers. We aim to widely provide a manufacturing method for artificial decorative veneers that can clearly express material transition colors, thereby contributing to the prosperity and development of this industry.

Traditionally, K boasts of artificial decorative veneers with this type of wood grain pattern.
In this method, a processed material veneer is created by applying an adhesive colored in the summer material transition color to the surface of the material veneer, which has been applied with one color in the spring material color, and forming a transfer ink layer. A widely known technique is to stack veneers of processed materials and press them together to form seven artificial flitches, and then slice the artificial flitch into four pieces.

However, in the above-mentioned conventional manufacturing method 4c, the adhesive easily penetrates into the inside of the male material board, and as a result, the resulting artificially decorated veneer has the disadvantage that the summer wood transition color tends to be unclear. Ta.

The present invention was made in view of the above-mentioned drawbacks of the conventional manufacturing method, and is extremely useful and full of novelty.

The method for manufacturing artificially decorated veneers of the present invention will be explained in detail below based on the examples shown in Figs. A veneer is created and cut into a predetermined size to create a collected wood veneer (1) with a thickness of 0.5%l and a strain of 2.01. In addition, depending on the required F1, the corresponding material veneer (1)
After applying degreasing layer and decoloring treatment, dyeing IIJIll
The spring wood of the desired natural wood is the same or approximately the same as that of the desired natural wood. Next, the surface of the material veneer (1) was coated with a surface WJ&C urethane material with a weight of a/xl to 60g/i.
The sealing layer (2) is formed by coating the resin at a rate of 40 g/wl or iEsog/d and irradiating it with an infrared heater or a shielded external heater to evaporate and remove water from the process margin. The urethane emulsion used at this time is preferably one of low viscosity (for example, below 2.0 onps Pi) and diluted with propylene carbonate or the like. Next, on the seal Jail (21), an adhesive (5) such as urethane resin colored with a dye or pigment in the same or approximately the same summer wood transition color as the desired natural wood is applied.
At the same time, a transfer ink layer (4) of the same color or substantially the same color as the desired natural wood summer wood color formed on the release sheet (5) is pressed, and the adhesive (3) is applied. This is transferred onto the wood veneer (1) to create a processed material veneer (6). Of course, the release sheet (5) is removed after the transfer. Next, a large number of veneers of the processed material are laminated with a transparent adhesive such as a urethane resin adhesive or a phenol resin adhesive interposed between them, and male and female veneers are applied to each inner surface from the top and bottom. In the relationship, press with a pair of presses +7) (71) having unevenness,
If the adhesive is hardened to form an uneven artificial flitch (8), and the artificial flitch (8) is sliced into a piece of paper, it will have a wood grain sII with a thickness of 0.2% to 2.0χ. An artificial decorative veneer (9) can be obtained. In the figure (101 is a slicing blade).

The manufacturing method of the artificially decorated veneer of the present invention is configured as described above, and since a sealing layer is formed on the surface of the wood veneer, the adhesive that is applied and formed on the sealing layer to express the transition color of the summer wood is applied. The agent does not penetrate into the interior of the veneer, and as a result, the summer wood transition area that is in contact with the transfer ink layer, which is the summer wood area of the resulting artificially decorated veneer, has the effect of becoming clear. There is.

Claims (1)

[Claims] 1) After forming a sealing layer on the surface of the spring wood veneer, a transfer ink layer of the summer wood color is formed on the sealing layer with an adhesive of the summer wood transition color. An artificial decorative veneer characterized in that a board is created, then a large number of veneers of the processed material are laminated and pressed together to form an artificial flitch, and then the artificial flitch is sliced into four pieces.
