Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field J] The present invention relates to a method for producing an artificial decorative veneer having a complex striped pattern on its surface.

[Background technology] Generally speaking, when manufacturing this type of artificially decorated veneer, rotary or sliced veneers are processed using a rotary or sliced veneer in a quantity of 90% Al-N, etc. By creating a flitch by laminating and pressing the flitch, and then slicing the flitch, we manufacture artificial decorative veneer in which the adhesive part looks like wood grain. The expression was monotonous and lacked a sense of naturalness, with no special expressions such as stripes.

[Objective of the Invention 1 The present invention has been made in view of the above points, and an object of the present invention is to provide a method for manufacturing an artificial decorative veneer that can exhibit a striped pattern and closely resemble natural wood. It is something to do.

DISCLOSURE OF THE INVENTION 1 That is, the method for manufacturing an artificial decorative veneer of the present invention involves pressing the surface of a wooden veneer 1 to form concave portions 2 and convex portions 3 in a striped manner on the surface of the essential veneer 1, and then The embossed veneer 4 is printed to dye only the convex portions 3, and then the dyed veneer 5 is heated.
After humidifying, a plurality of dyed veneers 5 are laminated and pressed using an adhesive to create a flitch, and then the flitch is sliced. By heating and humidifying the dyed veneer 5, , dye the entire veneer 4 lightly by smudging the staining agent on the 3 parts of the convex part, and leave the dark colored staining agent in stripes on the 3 parts of the 1 convex part, and then apply this dyeing agent Board 5
The above objective was achieved by creating artificial decorative veneer A using the following method.

The present invention will be explained in detail below. First, as shown in FIG. 1, the surface of a wooden veneer 1 obtained by slicing or rotary processing is pressed to form an embossing having striped four ff1S2 and convex portions 3 on the surface. Next, the surface of this embossed veneer 4 is printed. On the surface of the embossed veneer 4, dyed portions 6 are formed only in the embossed convex portions 3, as shown in FIG. 2 and fIS3. Next, water is added to this dyed veneer 5 and heated. As a result, the dyed veneer 5 will swell with water, the embossed recesses 2 will be restored to their original state, the printed surface will become flat, and the dye will bleed into the veneer 4, causing the veneer to swell. 4. The entire area is lightly dyed. The cross-sectional view at that time is shown in Fig. f54, and the plan view is shown in Fig. 5. 6 Next, after drying the dyed veneer 5 thus obtained, a plurality of sheets were laminated and pressed together using an adhesive. A flitch is created and the flitch is sliced to obtain an artificial decorative veneer A as shown in FIG.

By printing the embossed veneer 4 in which the concave portions 2 and convex portions 3 are provided in a striped pattern, the staining agent is applied to only the protruding portions of the surface of the veneer 4, so that the convex portions 3 are dyed. The staining agent is applied in a striped manner along the lines, and then by heating and humidifying the dyed veneer 5 coated with this staining agent, the staining agent smudges and stains the areas other than the convex portions 3 of the veneer 5. The inside of the veneer 5 is also dyed, and the parts of the surface of the veneer 5 that were the protrusions 3 are dyed darkly, and the other parts are dyed lightly, so that the veneer 5 has striped shading. will be formed. Therefore, a flitch is created using this dyed veneer 5,
In the artificial decorative veneer obtained by slicing this flitch, the hardened layer of the adhesive has a wood grain 7, and the dyed part has a striped pattern 8.

The present invention will be specifically described below based on Examples.

Apply an embossing roller to the surface of the veneer using an embossing roller with an unevenness of 0.1 mm. The surface of the board was printed, and then heated and humidified to obtain a dyed veneer. Next, after drying this dyed veneer, a plurality of veneers were laminated and pressed together using an adhesive to create a flitch, and the flitch was sliced to obtain an artificially decorated veneer. The resulting artificially decorated veneer had stripes.

[Effect of the invention 1 As described above, the present invention presses the surface of a wooden veneer to form concave portions and convex portions in a cotton-like manner, and then prints this embossed veneer to form convex portions. After dyeing only, then heating and humidifying this dyed veneer.

f! multiple pieces of dyed veneer through adhesive. Since the flitch was created by pressing the II layer and then slicing the flitch, the dyeing on the convex parts of the embossed veneer smeared throughout the veneer during heating and humidification, causing the entire veneer to be lightly dyed and the convex parts to be darkened. The dyed portions remain in a striped pattern, and the resulting artificially decorated veneer has complex stripes, giving it a natural look.
