Description

Detailed Description of the Invention

[0001]

[Industrial application] A method for manufacturing a decorative board in which a joining line pattern is formed between wood veneers.

[0002]

2. Description of the Related Art A decorative veneer in which a joining line pattern is formed between wooden veneers is conventionally manufactured as follows. That is, a plurality of small flitches are laminated with an adhesive to obtain a laminated flitch, and then the laminated flitch is cut so that a laminated portion appears.

However, in such a conventional veneer made by the conventional method, there is a problem in that the joining line does not appear clearly because the joining line is a small flitch.

Also, in order to clearly show the joining line,
It has also been attempted to attach a decorative veneer to a substrate and then form a groove along the laminated portion to perform colored coating to improve the design. However, because of such complicated steps,
There are difficulties in productivity.

Further, the following proposal has been made as Japanese Patent Publication No. 3-35083 as a method for producing a decorative veneer showing this kind of joining line.

That is, this proposal interposes a small piece of wood so that the cut surface of the wood fiber of the wood appears between the small flitches of the assembled flitch whose surface has grain or grain.
The laminated flitch is scraped off to obtain a decorative veneer, which is then attached to a substrate and the surface is colored.

[0007] Since this proposal is a decorative veneer that can be scraped by interposing small pieces of wood so that the cut surfaces of the wood fibers of the small flitches appear between the small flitches, the surface of the small pieces of the shredded wood has a mouth end surface. The colorant penetrates well, it is colored darker than other veneer parts, the design is improved, and the engraving of grooves is omitted, and productivity is improved. .

However, the wood veneer portion, which can be expressed only in a darker color than other veneer parts, has a mouth end surface. There is a problem in that productivity is not improved because the product is likely to be broken and peeled off during handling, resulting in a decrease in yield, and the handling must be done carefully.

[PROBLEMS TO BE SOLVED BY THE INVENTION] [PROBLEMS TO BE SOLVED BY THE INVENTION] To obtain a decorative veneer that has strength and a design line having a bonding line pattern by a simple method.

[0010]

[Technical Means] After a wood flitch F is prepared by adhering a wood block 1 with an adhesive, the wood flitch F is cut to obtain a decorative veneer C. Next, the decorative veneer C is bonded with an adhesive. Decorative plate P that is attached to the substrate 3 and is further colored and top-coated
2. The method for producing a decorative board according to the above method, wherein a veneer 2 made of a tree species different from that of the wood block 1 is interposed between the wood blocks 1.

[0011]

Since the wood block 1 and the veneer 2 of a different tree species are interposed, the thin veneer pattern of the veneer 2 is emphasized on the decorative veneer C thus collected.

[0012]

[Description of Configuration] The configuration of the method of the present invention will be described below with reference to FIGS. A wood block 1 is obtained by cutting wood. On the other hand, as shown in FIG. 1, the veneer 2 interposed between the abutting side ends of the wood block 1 is obtained by cutting wood using a cutting device such as a rotary racer or a slicer. Further, the veneer 2 used is of a tree species different from that of the wood block 1.

The difference in wood color or brightness is utilized by making the tree species different. The difference in material color or brightness is that the lightness index of the surface of the wood block or veneer is 5
The lightness index which is selectively used on the basis of 3 represents "brightness" and is measured by the colorimetric display defined by the International Commission on Illumination (hereinafter referred to as CIE).

The CIE display is expressed by three values of L (brightness), a (hue) and b (saturation), and the L value is used.

The L value is a lightness index representing the brightness of the object color, and the brightness is determined so that white is 100, black is 0, and gray is 50. Is 5
Of 0 and 55, the latter red color is brighter.

A plurality of wood blocks are juxtaposed with an adhesive agent between the abutting side ends of the wood blocks with a veneer having a different tree species from the wood blocks interposed between them.

As the adhesive used here, vinyl acetate resin, ethylene-vinyl acetate resin, epoxy resin, phenol resin, melamine resin, urea resin, acrylic resin or the like is used, and it does not damage the cutting tool during cutting. It is preferable to use one having hardness.

As shown in FIG. 2, the wood flitch F is cut in a direction orthogonal to the bonding surface to obtain a decorative veneer C. Decorative veneer C
The thickness is about 0.15 to 5 mm.

The decorative veneer C comprises a plurality of blocks 1 to be cut.
a is arranged in parallel with each other, and a bar-shaped veneer 2 having a different tree species from the block to be cut 1a is provided between the abutting side ends of the block to be cut 1a.
a is interposed.

The rod-shaped veneer 2a is formed as a fine line pattern in the abutting portion of the block 1a to be cut in the decorative veneer C, and the design is improved.

As shown in FIG. 4, the veneer 2a is cut only by being interposed between the ends of the wood block 1 facing each other at the mouth end, whereby a plurality of blocks 1a to be cut are arranged in parallel with each other, and the blocks to be cut are arranged. A decorative veneer C in which a rod-shaped veneer 2a is interposed only between the ends of the abutting sides of the lathe 1a may be used.

As shown in FIG. 3, the decorative veneer C may be adhered to the substrate 3 via an adhesive. The decorative veneer C may have a backing material adhered to its back surface in advance. As the adhesive, the same one as shown above is used.

As the substrate 3, plywood, fiberboard, particle board, laminated veneer, laminated wood, etc., which are commonly used, can be used alone or in any combination.

As shown in FIG. 2, in the decorative veneer C in which a plurality of blocks 1a to be cut are juxtaposed to each other and a rod-shaped veneer 2a is interposed between the ends of the blocks 1a to be cut. A colored paint is also applied to the surface of the decorative veneer C, a wiping treatment is applied, and an overcoat paint is applied, followed by drying.

As shown in FIG. 4, a decorative veneer C has a plurality of blocks 1a to be cut arranged in parallel with each other, and a rod-shaped veneer 2a is provided between the ends of the blocks 1a to be abutted with each other. In this case, the side surface butting portion except the rod-shaped veneer 2a portion between the butt ends of the wood mouth portion is cut to form a groove, and then the surface of the decorative veneer C including the groove is coated with a coloring paint. Coating, treatment with a wipe pin, further coating with a top coating, and then drying. In this way, as shown in FIG. 4, a decorative veneer P having a decorative veneer C attached thereto was obtained.

In the decorative veneer, the wood veneer and the rod-shaped veneer in the decorative veneer have different tree species. Therefore, the material color or the brightness is different, a fine line pattern is expressed, and the design is improved.

For example, the wood veneer is made of a dark color material and the rod-shaped veneer is made of a light color material, and conversely, the wood veneer is made of a light color material and the bar-shaped veneer is made of a dark color material.

Although they are similar colors, a wood veneer has a lightness index L value of 53 or more and a rod-shaped veneer has a lightness index L value of 52 or less, and vice versa. Configured with a lightness index L value of 53 or more for a single plate,

Alternatively, by constructing a wood veneer and a rod-shaped veneer so that both the material color and the lightness index are different, the contrast due to the hue and the brightness emphasizes the fine line pattern, and the designability is improved. improves.

[0030]

The decorative plate P to which the decorative veneer C is adhered, and the block 1a to be cut and the rod-shaped veneer 2a having different specific gravities are used. Is emphasized, a pseudo groove is formed between the abutting side ends of the block to be cut 1 to improve the design, and the productivity is improved without the need to engrave the groove.
