Description

[Detailed description of the invention] This invention relates to a laminated decorative veneer.

A laminated flitch is obtained by laminating and press-bonding multiple wood veneers using an adhesive, and the laminated decorative veneer obtained by slicing this flitch in a predetermined direction that intersects the laminated surface is called a baseboard. When press bonding to other materials, it is customary to impregnate the material with a resin such as polyester to strengthen the resin.

However, as the material for the laminated decorative veneer, low specific gravity materials such as agathis wood are generally used;
When resin impregnation is applied to this laminated decorative veneer, there are many resin-impregnated lids inside the veneer, which loses the unique texture of natural wood and gives it a strong impression of plastic, giving it a strikingly natural look. It has the disadvantage of impairing the

In particular, with laminated decorative veneers, components in the laminated veneer are removed during pretreatment such as decolorization in one step of the manufacturing process, so the texture is different from that of natural decorative veneers. In general, the resin impregnation treatment increases the plastic image, further increasing the deterioration of the natural appearance.

Therefore, an object of the present invention is to provide a laminated decorative veneer with a texture unique to natural materials.

An embodiment of the invention is shown in FIGS. 1 and 2. That is, this laminated decorative veneer 1 is obtained by slicing a laminated 7-rich laminated veneer obtained by laminating and press-bonding a plurality of wood veneers using an adhesive in a predetermined direction intersecting the laminated surface.
A composite veneer in which the cut surface of the wood material veneer has a wood grain pattern is obtained, and this composite veneer is impregnated with a resin solution mixed with mica flaky powder (Pearl Brace...manufactured by Nihon Kohei Kogyo Co., Ltd.). It was constructed by

The manufacturing process of this laminated decorative veneer l is as follows.

(1) A raw material veneer 2 obtained by rotary slicing Agatis wood is decolorized and dyed in a spring wood color dyeing bath 3 to obtain a spring wood color dyed veneer 4 (Fig. 2 (A) .

俤), (C)).

(2) A plurality of pieces of the spring wood color dyed veneer 4 are colored in the summer wood color, laminated with a colored adhesive, and pressed and bonded with the uneven mold 5 to obtain the uneven collection 171J Tsuchi 6 (same as above). Figure (to)).

(3) The uneven collection 1i71Jtsuchi6 is sliced at a predetermined slice angle that intersects the laminated surface thereof, so that the cut surface of the spring wood colored stained veneer 4 and the cut surface of the colored adhesive layer are in the cross section. Obtain a composite veneer 7 composited in a shape (same figure @), (F)
).

(4) The main ingredient is a polyester resin liquid for impregnation treatment of wood veneers, and this is used as a burl brace (particle size of 10 microns or less).
゛0.1~1. The resin liquid obtained by blending 0% is injected under reduced pressure into the composite veneer 7 described in I and subjected to resin impregnation treatment to form a laminated decorative veneer 1.
((G) in the same figure).

(5) The above is the manufacturing process of laminated decorative veneer, but in the manufacturing of decorative plywood using laminated decorative veneer 1 as the facing material, the base plate 9
A vinyl phrethane adhesive is applied on top, and the laminated decorative veneer 1 is bonded and molded onto the base plate 9 using the hot pressure press 10 using the adhesive, and finally the laminated decorative veneer 1 is sealed! ! Finish the surface with paint to make decorative plywood 11 ((6)l in the same figure)
(I)).

In this way, K11lfflt is then mixed with the burl brace, and the resin solution is injected into m 1 m of spring wood, which mainly consists of wood parts (consisting of spring wood color-dyed veneer 4), and is made of colored adhesive. Almost no light is injected into the summer wood part 1b, and therefore the burl brace is also impregnated into the spring wood fflE1m, and in the spring wood part 1, the incident light from the surface layer of the veneer is well reflected by the inner layer due to the burl brace. , spring wood @
1iK deep gloss can be imparted.

In addition to expressing the summer wood s1b of the laminated decorative veneer l, in addition to this, resin paper is inserted between the spring wood color-dyed veneers during laminated 7 richening, and the cut surface of this resin paper is used as the summer wood part. There is also a method of expressing this as follows, but in this case as well, in the resin impregnation treatment, injection of the resin into the summer wood portion is suppressed, and the same effect can be obtained.

1+. When expressing the summer wood part by transferring an ink layer or by a dark color printing process, impregnation of the summer wood part with the resin is unavoidable, but even in this case, if the summer wood part is dark colored, The reflective effect of the burl brace is lower than that of the spring material, and a difference in gloss between the spring material and the summer material can be caused to some extent.

In the above example, the manufacturing process of the decorative plywood was shown, but the pressing treatment of the laminated decorative veneer 1 in this process,
The burl braces impregnated into the laminated decorative veneer 1 are oriented horizontally, that is, parallel to the surface of the laminated decorative veneer 1, to further increase the reflection effect on incident light and give a deeper luster. This can further enhance the natural feel.

It is desirable that the blending ratio of the burl brace is set as in the above embodiment. For example, if this is set to 1Ω or more, the spring wood portion 1a made of wood will be reduced in the resin impregnation treatment.
The impregnated cover of the burl brace increases and adheres to the surface of the veneer, and together with the burl brace, it makes the entire veneer whitish and deteriorates its texture.

It is also advisable to set the grain size of the burl braces as in the example above.If the grain size is large, the penetration of the particles into the veneer will be inhibited, and the burl braces will not adhere to the surface of the veneer. It just sticks and you cannot get a deep gloss.

As described above, the laminated decorative veneer of the present invention is impregnated with resin mixed with mica flake powder, and can impart a deep luster to the surface of the material, giving it a texture unique to natural materials. It has the effect that it can be made into a laminated decorative veneer with a tinge of color.
