Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method for manufacturing artificial decorative veneers used as decorative materials for interior building materials.

[Background technology]

Artificial decorative veneer is used as a veneer for decorative boards.

This artificial decorative veneer is usually made as follows. That is, the veneers obtained by rotary lining are degreased and bleached and then dyed, the obtained dyed veneers are laminated with an adhesive, pressure molded to obtain an assembled flitch, and this is sliced. This is obtained by However, when the decorative veneer obtained in this way is attached to plywood and used as a veneer for a decorative board, the color of the wood grain pattern is expressed.

There was a problem that the pattern expression was monotonous and lacked a natural feel.

[Purpose of the invention]

The present invention was made in view of the above circumstances, and an object of the present invention is to obtain an artificially decorated veneer with excellent natural appearance in terms of color expression, pattern expression, etc. of wood grain patterns.

[Disclosure of the invention]

The inventors have made extensive studies to achieve the above object. As a result, this invention was completed.

In this invention, a laminated flitch is obtained using a wood veneer, and when an artificial decorative veneer is obtained using this laminated flitch, the laminated flitch is made between a bleached and uncolored wood veneer and a laminated flitch is placed between the bleached and uncolored wood veneers. The first gist is a method for manufacturing artificial decorative veneers, which is obtained by interposing a sheet material with good dyeability, and by slicing this assembled flitch and dyeing the sliced veneers. An artificial decorative veneer characterized in that a laminated flitch is obtained using a veneer, and in obtaining an artificial decorative veneer using this laminated flitch, the laminated flitch is obtained by interposing a transparent resin film between wood veneers. The gist of Foil 2 is the manufacturing method. This will be explained in detail below.

The first manufacturing method is to obtain a laminated flitch using a wood veneer, and when obtaining an artificially decorated veneer from this laminated flitch, the laminated flitch is made between a bleached and uncolored wood veneer and is dyed more than the wood veneer. By interposing a sheet material with good adhesion and dyeing the laminated sliced veneer obtained by slicing this laminated flitch, the color expression of the wood grain is the same color of the summer wood part and the spring wood part. This method is characterized by the ability to obtain an artificially decorated veneer with a more natural appearance.

Figure 1 is a side sectional view of a laminated state in which a wood veneer and a sheet material with better dyeability than the wood veneer are combined and laminated.
FIG. 2 is a perspective view of the flitch assembly according to the first manufacturing method. The wood veneer 1 shown in FIG. 1 is a veneer obtained by rotary lace, etc., which has been degreased and bleached.

A sheet material 3 having better dyeability than the wood veneer 1 is laminated on this wood veneer 1 via an adhesive 2. This operation is repeated in order to stack the layers, and then the layers are pressed together using a curvature mold. As a result, as shown in FIG. 2, an assembled flitch 4 is obtained in which a sheet material 3 having better dyeability than the wood veneers 1 is interposed between the wood veneers 1.

When this flitch assembly 4 is sliced, as shown in FIG. 3, a sliced veneer assembly 5 with a wood grain pattern formed by the sheet material 3 with good dyeability is obtained. Next, this assembled sliced veneer 5 is treated with an acid dye.

When dyed by a printing method or a dipping method using a coloring agent such as a direct dye, an artificially decorated veneer 6 as shown in Fig. 4 is produced.
is obtained. In this artificial decorative veneer, wood veneer 1
forms a wide summer wood part, and the sheet material 3, which has better dyeability than wood veneer, forms a spring wood part with wood grain. In this method, the laminated sliced veneer 5 is dyed, so the spring wood portion and the summer wood portion have the same color, resulting in a more natural look.

In addition, sheet materials with better dyeability than wood veneer include:
For example, fiber sheets such as non-woven fabrics and knitted fabrics, paper, wood veneers, etc. are preferably used.

Next, the second production method uses a wood veneer obtained by performing low-reduction slicing in the same manner as the first production method, and degreases and decolorizes it as usual.

The wood veneers are dyed and then laminated to form an assembled flitch. At this time, a transparent resin film is interposed between the wood veneers.

The artificial decorative veneer thus obtained is attached to plywood using a colored adhesive, and when used as a veneer for a decorative veneer, the lower layer of colored adhesive stands out due to the transparent resin film layer. It began to express a wood grain pattern with an excellent natural feel and deep color.

FIG. 5 is a perspective view of an assembled flitch according to the second manufacturing method, and FIG. 6 is a perspective view of an artificial decorative veneer. The wood veneer of the second manufacturing method is made by degreasing the veneer obtained by rotary lace.

It is used after being bleached and dyed. A transparent resin film 8 is interposed between the wooden veneers 7 via an adhesive, and this laminate is pressed using a white mold.
An assembled frituna 9 as shown in FIG. 5 is obtained. As the transparent visual film, for example, a vinyl hachloride resin film, a polyenalene resin film, a polypropylene resin film, a polyester fM film, etc. can be used. Among these, vinyl chloride resin film is particularly preferred.

After this, the flitch assembly 9 is formed to a thickness of 0.25 to 0.3, for example.
By slicing the veneer to about the same size, an artificial decorative veneer 10 having a wood grain pattern formed by the transparent resin film 8 and the veneer 7 as shown in FIG. 6 is obtained. This artificial decorative veneer 1
(After this, as shown in Figure 7 as a veneer,
It is used to form a decorative board 13 by bonding it to a base plate 12 via a colored adhesive 11. This decorative board 1
3, the colored adhesive 11 comes to float through the transparent resin film 8, and a wood grain pattern with a natural and deep color is expressed.

Examples will be described below.

(Example 1) A degreased and bleached wood veneer with a thickness of 2.11 mm and a non-woven fabric sheet with a thickness of 0.6 urn were alternately laminated with an adhesive and pressed using a curvature mold. I got a composite flitch. Next, the laminated frituna was sliced to a desired thickness to obtain an uncolored laminated sliced veneer. This veneer was coated with a pine-like colored liquid and printed. The resulting artificially decorated veneer had the same color in the spring and summer wood areas, giving it an elegant and natural feel.

(Example 2) A 0.6-thick transparent vinyl chloride resin film was laminated with an adhesive on a 2.0M thick degreased, bleached, and dyed wood veneer, and this process was repeated to obtain a laminate. The assembled flitch was obtained by pressing using a curvature mold. The flitch assembly was then sliced to a desired thickness to obtain artificial decorative veneers.

When this artificial decorative veneer was attached to plywood with a dark brown colored adhesive, the colored adhesive underneath rose through the transparent resin film, creating a deep and natural color. The wood grain pattern was rough.

〔Effect of the invention〕

The first production method according to @Ming is to obtain a laminated flitch from a wood veneer, and when using this laminated flitch to obtain an artificially decorated veneer, dyeing is better than bleached or uncolored wood veneer and wood veneer. The laminated flitch is formed by laminating sheet materials with good adhesion, and then it is sliced and the sliced veneer is dyed.The resulting artificial decorative veneer has a woody veneer with a summer wood part. A sheet material with better dyeability than wood veneer forms the spring material. Since these are dyed at the same time with the same dye, the spring wood and summer wood have the same color, giving it a more natural look.

However, in the second manufacturing method according to the present invention, when a laminated flitch is obtained from a wood veneer and an artificial decorative veneer is obtained using this laminated flitch, a transparent resin film is interposed during the laminated flitch formation. When the artificial decorative veneer obtained by slicing flitch is pasted to plywood using a colored adhesive, the colored adhesive underneath will stand out through the transparent resin film, giving it a natural-looking color. It is possible to express a wood grain pattern with a sense of depth. Moreover,
By changing the color of the adhesive, you can change the color that stands out and make the pattern stronger or weaker.
