In the example shown below, a flitch obtained by laminating material veneers such as 0-tally veneer or sliced veneer is cut out to obtain a laminated veneer with a scratch pattern appearing on the cut surface.
This example shows an example in which this veneer is colored to create a decorative board whose scratch pattern is colored to resemble the perforations in natural wood. The grooves appear as a scratch pattern on the surface of the laminated veneer cut from the flitch. That is, the laminated veneer is cut out from the flitch along the plane that crosses the boundaries of each material veneer, and the boundaries between the laminated veneers appear as a wood grain pattern on the cut surface, and each laminated veneer is cut along the boundary line. Linear grooves on the veneer appear in a row, creating a scratch pattern similar to the above embodiment. In order to provide linear grooves to each material veneer, as shown in Figures 2 and 3, rainbow boss 0-ru (
5), by using a roll with a wire brush (6), a cutter (not shown), or a combination of these,
The material veneer (
4) Formed over the entire surface, made of multiple veneers of material (
4), the above-mentioned flitch is formed by aligning the directions of the linear grooves (7). When applying the linear grooves (7) using the above-mentioned rainbow boss roll (6), the grinding process using the above-mentioned wire brush or other grinding tool is subsequently performed.
By this grinding process, a large number of notches are added to the groove wall of the concave groove formed by the pressure applied by the rainbow boss 0-ru (5), and this portion is finished into a large number of linear grooves (7). As described above, the reason why the grinding process is performed subsequent to the pressure treatment using the rainbow boss O-ru (6) is as follows. ■If only the embossed 0-ru is processed, the surface shape will return to its original shape due to water impregnation of the material veneer after processing with heat pressure, and the degree of unevenness will become smaller, resulting in a scratch pattern appearing on the laminated veneer. When grinding, the depth of the groove becomes shallower, making it difficult to express the hole surface itself, and less coloring material is taken into the hole, resulting in a decrease in coloring performance. The depth of the grooves does not decrease due to moisture absorption in the veneer, and the colorant can be reliably taken in. ■Thermo-pressure processing using an embossing tool requires processing the veneer at high temperatures and at low feed speeds.
Installation (+i# Not only is the cost high (but the productivity is also bad)
Furthermore, if only the embossed 0-rule is processed, as shown in Figure 4 (
As shown in a), the groove walls of the linear grooves (7) expressing the scratch pattern on the surface of laminated veneer +1 (11) become flat, and as a result, the coloring agent applied to finally color the scratch pattern becomes flat. As shown in Figure 4), the contact area with the groove is larger than that of the groove wall with a large number of notches (8) by grinding in addition to embossing. On the other hand, the size of the hole is small, and the amount of coloring agent taken in is insufficient, making it difficult to obtain a satisfactory coloring effect.However, the one that has been added with the grinding process has good staining with the coloring agent (9), and has good coloring performance in the hole area. Good. Of course, the same effect can be obtained by grinding the veneer using a grinding tool from the beginning without using an embossing roll.

<Example 2> On the surface of a 1.0 mm thick dyed veneer colored in the spring wood color,
As shown in Figure 2, embossed strips with a width of 0.5 to 1.5% are lined up at intervals of 2 to 50% along the width direction using an embossed roller (5+) at a roll temperature of 200°C and a feed rate of 1. .5MP
Processed under heat and pressure at a depth of 0.25 to 0.
.. 30 Linear grooves are formed, and from above, Figure 3~
The surface of the veneer is ground and roughened by rotating it at 30 rpm using a Y-P-Z Laser Roll (6) as shown in FIG. The wire brushes arranged around the circumferential surface of the wire brush should not have rounded or flat tips for the purpose of grinding, and should not open more than 2X in the width direction. It is arranged in Uy4B. A flitch is formed by stacking a plurality of veneers that have been surface-treated in this way, and the flitch is cut to create a woodgrain pattern on the cut surface between the veneers. By arranging the linear grooves of each veneer along this boundary line, we obtained a laminated veneer with a scratch pattern representing the holes in natural wood, and the surface of this laminated veneer. Next, apply a paint slightly darker than the spring wood color mentioned above and soak it into the scratch pattern that has become a recess, and use a wipe to remove the excess paint remaining on the surface of the laminated veneer other than the scratch pattern, and remove the scratch pattern. A decorative board was obtained which was colored in a natural pore-opening color.

<Example 4> On the surface of a 1.0% thick dyed veneer colored in the spring wood color,
A resin containing 100 parts of Ehifut 828 and 5 parts of etraethylene pentatrines was applied at 50 gr/d and cured at 90°C for 5 minutes to form a resin layer on the surface of the material veneer. 57 The cutlery (11) having a V-shaped cutting edge as shown in Figures (a) and (b) is arranged at 2fi intervals in the width direction and rotates at 120 rpm with a diameter of 150 wa.
Grind the surface with a grinding tool (121) to a depth of 0.3 mm to form a large number of linear grooves (7) aligned in one direction on the surface of the resin layer, and then grind the surface again by sand blasting. After that, multiple sheets of material veneer are laminated with adhesive to create a flitch, and this flitch is cut to obtain a decorative board with each linear groove appearing as a scratch pattern on the surface, and the rest is carried out as described above. The scratch pattern is colored in the same manner as in the example above.In the above example, a large number of linear grooves are formed by cutting the veneer, so the linear grooves are formed by the moisture absorption of the veneer. These linear grooves, which do not disappear or decrease in depth, appear on the surface of the laminated veneer cut from the flitch obtained by laminating these veneers, forming a clear scratch pattern, giving it a three-dimensional effect and coloring. It has good performance and can produce a decorative board with a pattern that closely resembles the perforations in natural wood.

In the method for producing artificial decorative boards described below, flitches obtained by laminating material veneers with fibrous sheets pasted on the surface are cut, and the decorative boards have a Skra Sochi pattern on the surface that closely resembles perforations. A method for obtaining the board is disclosed. Generally, a composite veneer is formed by pasting a fibrous sheet such as paper or non-woven fabric onto a rotary veneer or sliced veneer using an adhesive, and an embossed O-ru is placed on top of the fibrous sheet of the composite veneer. After applying pressure to form concave grooves on the surface, the flitch obtained by laminating this composite veneer is cut, and the cut surface shows a wood grain pattern on the border between each board, and the cut surface is cut along the border. One possible method is to line up the grooves of each veneer to create a scratch pattern that resembles the perforations found in natural wood, wood, and oak, but if the fibrous sheet used is thick, the scratch pattern shown in Figure 6. As seen in Figure 2, a fibrous sheet α4 is placed between the veneer 0) and the veneer il+ on the surface of the resulting laminated veneer 05).
) appears as a thick band, and the appearance is very different from that of natural materials.Also, if the fibrous sheet is thin, most of the adhesive will penetrate into the sheet when combined with the veneer. , when creating a flitch by laminating composite veneers after forming grooves through embossing, the adhesive used in the fibrous sheet composite overlaps with the adhesive used to form the flitch, and as a result, the laminated veneer is cut out from the flitch. Thick stripes of both adhesives are concentrated on the surface of the material, and during the subsequent surface painting process, these thick stripes of adhesive create an appearance that is far from natural. . The embodiment shown below is intended to solve the above-mentioned inconvenience, and as shown in Fig. 7, a pair of 0-tally veneers or sliced veneers is interposed between a pair of 0-tally veneers or sliced veneers with an adhesive layer interposed between them. After sandwiching the fibrous sheet 04) to create a Santoifuchi composite, and decolorizing or dyeing this composite by dipping treatment or steel rinsing treatment, the water absorption effect of the fibrous sheet Q4) that occurs during this treatment. Using the delamination phenomenon based on
4) Peel it off at the center to obtain a composite veneer with one half of the fibrous sheet on the surface, form grooves on this composite veneer from above the fibrous sheet with an embossing roll, and then press in the direction of the grooves. A flitch is obtained by laminating multiple composite veneers with adhesive, and from this flitch, a laminated veneer is cut out in the same manner as above, and finally, the scratch pattern that appears on the surface of the laminated veneer is colored. administer. According to this method, a fibrous sheet interposed between a pair of veneers via an adhesive causes delamination in the center, which is the area not impregnated with adhesive, due to water absorption, and the surface of each veneer is restored. A fibrous sheet is formed that is approximately half the thickness of the composite veneer, and has minute indentations on the outer surface due to delamination, and the laminated veneer cut from the flitch using this composite veneer has As mentioned above, on the surface of the laminated veneer cut out from the flitch, thick stripes due to the fibrous sheet and thick stripes concentrated from the adhesive used when forming the composite veneer and the adhesive used when forming the composite veneer appear. Moreover, the concave grooves that are added to the composite veneer using an embossed o-ru are formed in the adhesive layer that hardens when the veneers are combined, and the old configuration with the embossed o-ru is not possible. In addition to being easy to carry out, the presence of the fibrous sheet with the above-mentioned surface bulges covering each concave groove makes it possible to reduce the amount of fibrous material that appears on the surface of the laminated veneer obtained by cutting out the flitch made of this composite veneer. The groove wall of the above-mentioned concave groove, which is a component of the scratch pattern that expresses the hole opening, becomes a rough surface with minute indentations due to the hangnails of the fibrous sheet, and as a result, this laminated veneer is -t') processing, that is, wiping off the excess coloring that remains on the surface after coloring is soaked into the scratch pattern, and entering into each groove of the scratch pattern when highlighting the scratch/υchi pattern by coloring. A large amount of the coloring agent is absorbed by the rough surface effect, and the coloring process of the scratch pattern is performed more effectively, and the scratch pattern can be expressed by coloring the pores, which closely resembles natural wood.

As described above, the present invention provides the surface of the veneer with a scratch pattern that resembles the perforations found in ring-hole materials such as natural KeP+ wood and oak wood, and applies a coloring agent to the surface of the veneer. Although the above-mentioned Sukura Sochi pattern, which is a recessed area, is impregnated with a coloring agent, it has the advantage that the perforations can be expressed in a more natural form by both the uneven Sukura Sochi pattern and the coloring. be.
