Description

[Detailed Description of the Invention] The present invention relates to a method for manufacturing a decorative veneer,
The purpose is to provide a method for manufacturing a decorative veneer that closely resembles natural wood, with a leather part, a spring material, and a gold plate surface.

An embodiment of the present invention will be explained based on the entire story 1 or G). That is, this decorative veneer manufacturing method is
As shown in Figures (5) to G), an adhesive 2 is applied on a veneer 1 of the material for expressing the capital of the right material, and a non-woven fabric for expressing the back material is impregnated with polyethylene glycol-methacrylate on the upper surface. 3 and bonded with adhesive 2, a plurality of obtained FC composite veneers 4 are laminated in mold 5 via adhesive, and pressed and bonded to form an assembled flitch 6 (l-obtained). A decorative veneer 7 is obtained by slicing the flitch 6.

By impregnating the polyethylene glycol methacrylate into the non-woven fabric 3, which has inferior light resistance compared to the wood veneer 1, the light fading of the non-woven fabric 3 is reduced, and the cable material 4 is made to have almost the same opacity as the board 1. It imparts light resistance. Therefore, by impregnating the gold-free cloth with such a light resistance imparting agent, the summer material 89 (
This makes it possible to eliminate the effects of fading quickly due to the strength of the non-woven fabric (non-woven fabric), making the summer wood portion 9 more noticeable due to changes over time, and giving a sense of discomfort. As a result, the range of Futekifu that can be used to express summer habe has expanded significantly.

It has the advantage of not being restricted by materials, etc.

Finally, a test example based on this example will be given.

K test example 1: Non-paper cloth made of rayon bulbs was colored with a predetermined color for the lever part, and then polyethylene glycol methacrylate (polymerization degree of polyethylene glycol part: 350)
) and dried in the heat.

On the other hand, all Agatis rotary veneers with a thickness of 10 mm are dyed in the specified color, and then composited with the nonwoven fabric using an adhesive. Multiple sheets are stacked in a mold, pressed and glued, and flitched. This flitch was completely sliced to obtain a decorative veneer.

When the veneer was subjected to a 48-hour chromochromic acceleration test using fade-o-make with carbon arc, the discoloration color difference ΔE of the spring wood section was 7, while the discoloration color difference of the summer wood section was ΔE was 85, and the degree of discoloration of both samples was almost the same.

Note that similar results were obtained when other fibrous sheets such as paper were used in place of the nonwoven fabric.

Another embodiment of the invention will be described based on FIG. That is, in this method for producing decorative veneer, a brightening agent is mixed into a fibrous sheet such as paper or nonwoven fabric used for summer clothing in order to impart luster to the wide summer material.

Conventionally, as a method of imparting luster to the summer material, a method is known in which a brightening agent is mixed into the adhesive 10 that adheres the material veneer 1' to the gold, as shown in FIG. It gave gloss to both the wood and spring wood, and it was not possible to express the entire summer wood clearly, so it could not be used to express wide summer wood.

Therefore, by completely mixing the brightening agent into the fibrous sheet, it was possible to express the entire width and clear summer wood part, and also to add luster to this summer wood part.

The brightener is mixed into the fibrous sheet when the fibrous notebook is made, or mixed with a coloring agent during coloring after the paper is made. The rest is the same as the previous embodiment.

Next, a test example based on this example will be given.

Test Example 2: After making a 10 mils (approximately 0.254 mils) paper, the color of the paper'f:summer wood part was colored with a coloring agent mixed with a brightening agent (a burr agent that completely adhered titanium to the surface of mica powder). It was colored.

This paper was dyed in the spring material color and glued onto the fc material board.
Multiple sheets of the resulting composite veneer are layered in a fully textured mold, pressed and glued to obtain a flitch, and by slicing all of this flitch, a decorative veneer with a wide, glossy and clear summer wood part is created. A board was obtained.

Still another embodiment of the invention will be described based on FIGS. 3 and 4. That is, the method for manufacturing this decorative veneer is as shown in Figures M3 (A) to C), in which a coloring agent is dissolved in a bath agent containing % (After applying a substantially incompatible solvent to the part, then immersing it in coloring 'a12' and drying it to Arashiza Toiro (IA color C1). It is layered and composited.

In this way, since the incompatible solvent coated portion 11 is only lightly colored compared to other portions, color unevenness is formed in the fibrous sheet 3' colored in the summer wood color. The decorative veneer 7' obtained by using such a fibrous sheet 3' together with the grained veneer 1'' for the spring material section has uneven coloring in the summer material section 9', giving it an extremely natural feel. It becomes.

In addition, as another method for expressing color unevenness, a coloring liquid containing coloring agents such as pigments and paints of Natsuzai Toiro in advance is partially applied to the fibrous sheet, and then the coloring is applied. By immersing it in the solution and coloring the entire piece in the color of summer wood, the parts that have been partially coated with the coloring agent will be darkly colored.

Next, all test examples based on this example will be given.

Test Example 3: Paper was used as the wood for expressing the summer wood of a pine tree, and after partially applying water to the paper, it was dipped in oil-soluble ink to form color unevenness. Next, it was bonded to a vermilion wood veneer with a soft spring wood color using adhesive, and then composited.
The plurality of sheets are laminated with adhesive in the uneven shape, pressed and bonded to obtain a laminated flitch, and when this flitch is sliced, a soft decorative veneer with color unevenness expressed on the skin material is obtained. I was able to do that.

In addition, the expression of color unevenness was not limited to the summer wood part, but also to the material veneer for expressing the pottery group when coloring it in the same way as the summer wood part.

As described above, the method for manufacturing a decorative veneer of the present invention involves laminating a fibrous sheet for expressing the summer part on a material veneer for expressing the spring material and bonding it with an adhesive, and producing a composite veneer. By laminating multiple boards in a mold using adhesive, pressing and gluing them together to obtain a laminated flitch, and slicing this laminated flitch, the summer wood portion and spring wood portion, which closely resemble natural wood, are made into boards. It has the effect of being able to be expressed on the surface.
