Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method for manufacturing a laminated decorative veneer that is used by being attached to the surface of plywood or the like as a veneer.

C￥1' Kifujutsu 1 Laminated decorative veneer 1, Laminated decorative veneer 1 that is in good condition is for example 1
figure,! @2 Manufactured as shown in Figure.

That is, a veneer 2 made by rotary or slicing raw wood is dyed or otherwise dyed, a large number of veneers 2 are stacked with an adhesive layer interposed therebetween, and the veneer 2 is molded into a mold having a concave surface 3 as shown in Fig. 1. 4 and a mold 6 having a convex surface 5 and pressed together to create a deformed 7-7 chip 7, and this frit 7 is cut across the loading surface by a cutter 8 as shown in FIG. By slicing on the surface, the sliced end of the veneer 2 appears as a wood grain pattern! 1 board 1
is obtained. By attaching this laminated decorative veneer 1 to a base plate such as plywood as a veneer, a chemical MR can be constructed. However, the laminated decorative veneer obtained as described above has a problem in that it has poor graininess and is difficult to form with a smooth and glossy surface. In other words, when producing laminated decorative veneers, the veneers are colored to the desired color, but at this time various chemical treatments are applied, and the wood scent unique to pine is also decomposed at the same time. In addition, at this time, lignin and other substances are decomposed and extracted components are extracted from the wood, resulting in unfavorable conditions such as an increase in the porosity of the wood. This causes the surface of the veneer to lose its smoothness and luster. Moreover, it is impossible to express the feel of pine resin with this laminated decorative veneer. Even if the veneer is finished in a color tone similar to natural wood, the laminated decorative veneer will end up looking like natural wood.
i.

[Objective of the Invention 1] The present invention has been made in view of the above-mentioned problems, and aims to produce a laminated decorative veneer having a wood aroma and a smooth and glossy surface! The first objective is to manufacture a laminated decorative veneer that expresses the feel of pine resin.

[Disclosure of the Invention] However, in the method of manufacturing a laminated decorative veneer according to the present invention, a large number of veneers are stacked with an adhesive and pressed together to create a flitch, and the flitch is The present invention is characterized in that frits are created using oleoresin when producing laminated decorative veneers by slicing in a plane that intersects with the mounting surface, and the above purpose is achieved by using oleoresin. The present invention will be described in detail below with reference to Examples.

The present invention uses oleoresin to create fritches. First, a case will be described in which oleoresin is applied to the surface of a veneer.

Oleoresin, also known as balsam, is a viscous liquid secreted by scratching a natural tree such as the pine genus.
It has a rich woody aroma. This oleoresin is then applied to the veneer before making the fritsch, but in order to apply oleoresin to the veneer, the oleoresin is mixed with a staining liquid such as pine spring wood color, and then the staining liquid is applied. This can be done by applying oleoresin at the same time as dyeing, or by applying a diluted solution of oleoresin after dyeing the veneer. Oleoresin is oil-soluble, so when oleoresin is used by mixing it with a dyeing solution, it is necessary to use an oil-soluble dye as well, and when oleoresin is used diluted, oleoresin is mixed with toluene. It is necessary to dilute it in a soluble solvent such as xylene, sunalene, etc. When oleoresin is applied to the veneer as described above, the oleoresin impregnates and permeates into the veneer. A large number of veneers 2 that have been dyed and coated with oleoresin in this way are stacked together using an adhesive that has been colored in the color of pine summer wood, etc., and then placed in a mold 4 as in the case of Fig. 1. A deformed 7 lift 7 is created by pressing with . The slice i side of the eyebrows of the adhesive becomes the spring wood part and the summer wood part, respectively, and a composite decorative unit 1i1 that appears like a pine woodmata is obtained. And this composite makeup 11
In L[, the veneer is impregnated with oleoresin, so the oleoresin can emit wood fragrance, and the oleoresin fills the voids in the structure of the veneer. It can be made into a smooth and glossy laminated decorative veneer.

Next, the case where an oleoresin is mixed and used in an adhesive when creating a frit will be explained. As the adhesive, a moisture-curing polyurethane adhesive colored in the color of pine wood or the like can be used. For example, 10 parts by weight of oleoresin is mixed with 100 parts by weight of this polyurethane adhesive. Since oleoresin is insoluble in water, the adhesive must be oil-based. Then, this adhesive is applied to the surface of the veneer colored in pine spring wood color, etc., a large number of veneers are mounted on Mt through the adhesive, and this is placed on the first
As in the case shown in the figure, a deformed fritch 7 is created by pressing with the mold 4.6, and this 7-lift 7 is
As shown in the figure, by slicing with the cutter 8 on the plane that intersects with the loading surface, the sliced end surface of the veneer 2 becomes the spring wood part, and the sliced edge of the adhesive layer becomes the summer wood part. A laminated decorative veneer 1 that appears as a pattern is obtained. In this laminated decorative veneer, the adhesive layer that forms the summerwood part contains oleoresin, giving the summerwood part a pine resin-like luster and adhesiveness.

Note that in addition to applying oleoresin to a veneer, it is also possible to mix oleoresin with an adhesive to produce a laminated decorative veneer. As a result, the surface becomes a smooth surface with gloss, and furthermore, it is possible to obtain a laminated decorative veneer with a feel of pine resin in the summer wood part.

[Effect of the Invention J As described above, in the present invention, oleoresin is used to create 7-stripes and the frits are sliced to produce laminated decorative veneers. It is possible to produce a laminated decorative veneer with a wood aroma and a smooth surface with a glossy surface by using oleoresin, and it is also possible to produce a laminated decorative veneer with a pine resin feel on the summer wood part by using oleoresin. It is possible.
