Abstract

PURPOSE:To improve decorative effect, prevent the strength of a wooden veneer from deteriorating at the junctioned part, and ameliorate ease of handling and productivity by forming a steric effect-rich block pattern without the necessity to carve a groove on the surface in the preparation of the decorative board by attaching the decorative veneer with the block pattern formed using the wooden veneer. CONSTITUTION:A sheet-like material 2 with properties to prevent at least, a finishing paint from being absorbed is allowed to be present between wooden blocks 1 and is bonded using an adhesive to obtain a wood flitch. Next, the wood flitch is cut to obtain a decorative veneer, and the decorative veneer is bonded to a base 7 through the adhesive, then the surface of the veneer is coated in color and finish-coated to obtain a decorative board. The decorative board consists of a thick finish-coated layer 10 formed on the sheet-like material due to its absorption preventive properties, forming a finish-coated projecting part 11 to realize a steric effect.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a decorative board,
In particular, the present invention relates to a method for manufacturing a decorative veneer in which a decorative veneer in which a block pattern of a wooden veneer is expressed is attached to a substrate.

[0002]

2. Description of the Related Art This type of decorative board has heretofore been formed by laminating a plurality of small flitches via an adhesive to form a laminated flitch.
It is manufactured by cutting this laminated flitch into thin pieces in the direction in which the laminated portion appears so as to obtain a decorative veneer in which a block pattern of a wooden veneer is expressed, and sticking this decorative veneer on a substrate. In the decorative veneer, the laminated portion is not clearly expressed, so that it has a drawback of poor design.

Therefore, in order to emphasize the laminated portion, such a decorative veneer is attached to a substrate, a groove is formed along the laminated portion, and further colored coating is performed. However, the work process was increased and the productivity was very low.

In view of such a problem, a small piece of wood is interposed between the small flitches of the assembled flitch having grain or grain on the surface so that the cut surface of the wood fiber of the wood appears, and the integrated flitch is scraped off. Japanese Patent Publication No. 3-35083 proposes a method of obtaining a decorative veneer, sticking it to a substrate to form a decorative veneer, and coloring the surface.

According to this prior art, since the small piece of wood is interposed between the flitches so that the cut surface of the wood fiber of the wood appears, the decorative veneer obtained by scraping the assembled flitch has the mouth of the small piece of wood. A surface appears and is colored darker than other parts because of good penetration of the colorant in this part. Therefore, there is an advantage that a decorative plate having an excellent design property can be obtained.

[0006]

However, in the case of the above-mentioned prior art, the laminated portion made of small pieces of wood is always expressed in a darker color than the other portions, which limits the design.

In addition, since the wood mouth surface of the small wood piece appears on the surface of the decorative veneer, the bending strength and the tensile strength in this part are greatly inferior, and when the decorative veneer is handled, breakage or peeling occurs at the laminated portion. However, there is a problem in that the yield is lowered.

Furthermore, according to this conventional technique, since it is not necessary to engrave a groove, the productivity is originally high, but as described above, the handling must be done carefully, and therefore the production is actually performed. It was difficult to improve the sex.

[0009]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problems of the prior art, has excellent designability, has sufficient strength, does not cause any particular difficulty in handling, and has a high productivity. The purpose is to provide a manufacturing method.

To achieve this object, the present invention provides a wood flitch by bonding at least a sheet-like material for preventing the inhalation of an overcoat paint between wood blocks to form a wood flitch, and then cutting the wood flitch. Then, the decorative veneer was obtained, and the decorative veneer was adhered to the substrate with an adhesive, and the surface was colored and overcoated to form the overpainted convex portion on the sheet-like material. The proposal is to use a decorative board.

It is essential that the sheet-like material has at least the property of preventing the inhalation of the top-coat paint, but it may also prevent the inhalation of the colored paint.

[0012]

[Function] Since the sheet-like material has the property of preventing the inhalation of the top-coat paint, the top-coating applied on the decorative veneer causes a thicker coating film than the wood veneer on the sheet-like product. Then, a top-coating coating convex portion is formed. This top-coating convex portion acts like a convex lens and clearly expresses the boundary portion of the decorative veneer.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method of manufacturing a decorative board according to the present invention will be described below with reference to the accompanying drawings.

A wooden block 1 obtained by cutting wood
A sheet-like material 2 for preventing the suction of the top-coating paint used later during the top-coating is interposed between the ends on the abutting side of, and they are arranged arbitrarily, and they are assembled and fixed via an adhesive to obtain a wood flitch 3 ( (Fig. 1).

As the sheet-like material 2 having such properties, paper, cloth, non-woven fabric, veneer, fiber board, etc., which are coated or impregnated with synthetic resin, paint or the like are used. Synthetic resin or paint to be applied or impregnated includes acrylic resin, alkyd resin, phenol resin, urea resin, melamine resin, unsaturated polyester resin, epoxy resin, polyurethane resin, vinyl chloride resin, vinyl acetate resin, polyvinyl alcohol, polyethylene. Etc. are used. Alternatively, the sheet-like material 2 itself may be formed of a material having a property of preventing the top-coat paint from being sucked.

The sheet-like material 2 must be one that can be cut by a blade of a cutting device such as a slicer used when the wood flitch 3 is cut later to obtain a decorative veneer.

The sheet material 2 can be optionally colored in advance.

As the adhesive used for obtaining the wood flitch 3, synthetic resin adhesives such as vinyl acetate resin, ethylene-vinyl acetate resin, epoxy resin, phenol resin, melamine resin, urea resin and acrylic resin are suitable. Is. Further, as these adhesives, those having a hardness that does not damage the blade of the cutting device when cutting the wood flitch 3 described later are used.

The wood flitch 3 is thinly cut in the direction orthogonal to the bonding surface, as shown by the dotted line in FIG. 1, to obtain the decorative veneer 4 of FIG.

In this decorative veneer 4, a sheet-like small piece 6 made into a rod shape by cutting is interposed between the ends of the wooden veneer 5 on the abutting side.

The surface of the decorative veneer 4 can be optionally coated.

The thickness of the decorative veneer 4 is generally 0.15 to 5 m.
It is about m.

The obtained decorative veneer 4 is attached to a substrate 7 to form a decorative plate 8 (FIG. 3). The adhesive used in this case may be the same as that described above as the adhesive used in obtaining the wood flitch 3.

The substrate 7 may be a common material such as plywood, fiber board, particle board, and laminated veneer, and these may be used alone or in any combination.

Next, a colored coating material is applied to the surface of the decorative veneer 4 to form a colored coating film layer 9, and then a wiping treatment is performed.
Further, after coating the top coating composition to form the top coating layer 10,
dry.

As shown in FIG. 4, in the decorative veneer 4,
Since the rod-shaped sheet-like small piece 6 interposed between the abutting side ends of the wood veneer 5 has a characteristic of preventing the top-coat paint from being sucked, the top-coating coating film 1 is formed on the sheet-like small piece 6.
0 is formed in a thick shape and becomes the top coating convex portion 11. As a result, the block-shaped pattern formed by the wooden veneer 5 is clearly revealed.

In the illustrated embodiment, the wood flitch 3 is formed by interposing the sheet-like material 2 between the ends of the wooden blocks 1 in the longitudinal direction and the mouth end, but the wooden blocks 1 are joined in the mouth end in the mouth end direction. You may intervene only between. In this case, the abutting side end of the wood veneer 5 in the longitudinal direction is not clearly expressed in the decorative veneer 4, and therefore, before applying the colored paint, cutting from the surface along the abutting side end in the longitudinal direction. It is preferable that the groove is formed by processing so that the block-shaped pattern of the wood veneer 5 is more emphasized.
