Description

[Detailed description of the invention] (Technical field) The present invention relates to a method for manufacturing artificially decorated veneers.

(Background technology) Conventionally, this type of artificially decorated veneer is produced by coloring a material veneer, then laminating a large number of material veneers and pressing them together to form a flitch, and then applying the 7-rich material to a flitch. Obtaining it by cutting was a publicly known technique.

However, the artificial decorative veneer obtained by the above-mentioned conventional manufacturing method has a lot of color unevenness, especially when coloring the material veneer.
The degree of coloring often differed, resulting in uneven coloring of the artificially decorated veneer.

(Purpose 2 of the present invention) The present invention has been made for the purpose of eliminating all of the drawbacks of the above-mentioned conventional manufacturing methods.

(Disclosure of the Invention) The present invention will be described in detail below with reference to the embodiment drawings of FIGS. 1 to 6.

In the present invention, raw wood such as agathis wood or lauan wood is rotary cut and cut into a predetermined size, and a material veneer (1) with a thickness of 0.2% to 2.0% is dyed and then urethane adhesive is applied to each. While stacking a large number of sheets with
o Q/cJ, pressed under conditions of 4 hours to form an uneven flitch 14), and then the 7 riches (4) were sliced to form thin pieces 15) with a thickness of 0.2% to 1.0%. After creating the thin piece +53, the artificial decorative veneer L was immersed in warm water at a temperature of 71)'C to 90°C (after being immersed in water for about 1 hour, air-drying was performed). (2) in the figure shows the staining solution.

In the present invention, the dye used to dye the material veneer +11 is, for example, Numinol manufactured by Kaito Kagaku Kogyo Co., Ltd., which facilitates dyeing.

(Effects of the Invention) The method for producing artificially decorated veneers of the present invention is configured as described above, and even if the degree of dyeing is uneven at the raw veneer stage, by immersing the thin pieces in a hot bath, The higher the dyeing concentration, the more intense the dye is removed, and as a result, the degree of dyeing is approximately equalized, which has the effect of preventing color unevenness from occurring in the artificially decorated veneer.Especially the material. If the dye used to dye the veneer is an acid dye or a direct dye, the dyeing progresses toward equilibrium in the dye concentration in a hot bath, so the effects of the present invention are significant.

[BRIEF DESCRIPTION OF THE DRAWINGS] Figures 1 to 6 are embodiment drawings relating to the method for manufacturing artificially decorated veneers of the present invention, and Figure 1 is a perspective view of the material veneer, wcz
The figure is a sectional view of the main part showing the state in which the material veneer is dyed, Figure 3 is a side view showing the state in which fringe is formed, and Figure 4 is a side view showing the state in which the fringe is formed.
The figure is a perspective view showing the state in which the thin piece is made, FIG. 5 is a cross-sectional view of the main part showing the thin piece in a hot bath, and FIG. 6 is a perspective view of the artificially decorated veneer.

Claims (1)

[Claims] 1) After coloring a veneer of the material, a large number of veneers of the material are laminated and pressed together to form a flitch.Then, the flitch is cut to create a thin piece, and the thin piece is soaked in hot bath liquid. A method for manufacturing artificially decorated veneer, which is characterized by immersion in the interior.
