Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative veneer used as a building material or a plate for furniture in a house and a method for manufacturing the veneer.

[0002]

2. Description of the Related Art Conventionally, a decorative veneer is pasted on the surface of a substrate with an adhesive, then a colored paint is applied to the surface of the decorative veneer to apply a colored coating, and then a top coat is applied and overcoated. It is widely practiced to apply a paint to form a surface protective layer to form a decorative plate.

[0003]

In the above-mentioned prior art, in order to give the surface protective layer a sufficient function, it is necessary to repeatedly apply the overcoating material and thickly apply it, which complicates the working process.

Further, in the case of attempting to perform thick coating using a paint having a high viscosity, if the coating speed or the drying speed is high, uniform coating cannot be performed, and foaming occurs during drying. Although all of these problems are avoided by slowing down the speed, a decrease in productivity is inevitable.

Under the circumstances as described above, it has been attempted to give up the thick coating of the top coat and form a relatively thin surface protective layer. In this case, the strength of the surface protective layer becomes weak. Therefore, there are problems that the surface is easily scratched, the abrasion resistance is poor, and a deep makeup surface cannot be obtained.

[0006]

SUMMARY OF THE INVENTION The present invention aims to solve the above-mentioned problems of the prior art, and more specifically, to stably supply a high-quality decorative veneer by a relatively simple work process. However, the aim is to improve productivity.

The decorative veneer according to the present invention, which has been devised after intensive efforts to achieve the above object, has a pattern printed on its surface, and an adhesive which becomes transparent or becomes transparent when cured is further formed on the upper surface thereof. It is characterized in that a surface protective layer is formed by adhering a transparent synthetic resin sheet through the surface.

In the method for producing a decorative veneer according to the present invention, a pattern is printed on the surface of the decorative veneer, and then an adhesive that becomes transparent or becomes transparent when cured is applied to the upper surface of the decorative veneer. The transparent synthetic resin sheet is placed and pressure-bonded to form a surface protective layer of the transparent synthetic resin sheet.

As the decorative veneer, slice veneer, rotary veneer, half-land veneer, sword veneer, etc. obtained by a cutting and cutting device such as a slicer, a rotary race, a half-land rotary race, a circular saw and a band saw are used. To be The decorative veneer generally has a thickness of 0.15 to 5 mm.

On the back surface of the decorative veneer, Japanese paper, foreign paper, synthetic paper,
A backing material such as a non-woven fabric, a woven fabric, a gauze cloth, an impregnated paper, a synthetic resin sheet or the like may be stuck and used. By sticking the backing material, the decorative veneer itself can be reinforced, the decorative veneer can be prevented from cracking, and the adhesive can be prevented from seeping out to the surface of the decorative veneer. At the same time, the ease of handling can prevent cracks and improve productivity. The backing material may be applied to each leaf of the decorative veneer or may be continuously applied to a plurality of decorative veneers.

By designing an arbitrary pattern such as a wood pattern, a conduit groove pattern, an abstract pattern, a mosaic pattern, etc. by printing on the surface of the decorative veneer, the design can be improved. The pattern may be formed by printing directly on the surface of the decorative veneer, or may be formed by subjecting it to a base treatment such as coloring coating or sealer coating, if necessary. Print pattern formation is letterpress,
It is performed by using any printing method such as intaglio, gravure, gravure offset, silk screen, and transfer.

After applying an adhesive, which is transparent or becomes transparent when cured, onto the upper surface of a decorative veneer on which an arbitrary pattern is printed by using a coating device such as a sprayer, a spreader, a flow coater, a curtain coater, or a bar coater. Place a transparent synthetic resin sheet. The transparent synthetic resin sheet is
The decorative veneer is placed on the upper surface of the decorative veneer for each leaf or continuously over a plurality of decorative veneers.

The transparent or transparent adhesive used at this time is a vinyl acetate resin-based, urea resin-based, melamine resin-based, phenol resin-based, acrylic resin-based, urethane resin-based, isocyanate-based adhesive, etc. It is used alone or as a mixed adhesive which is arbitrarily mixed. A colorant may be added to this adhesive as needed to use it as a colored adhesive. The adhesive itself is transparent, or at least becomes transparent when cured, and therefore, the surface of the decorative veneer is not hidden.

As the transparent synthetic resin sheet, polyethylene sheet, cellophane, acetate sheet, polyvinyl chloride sheet, polypropylene sheet, polystyrene sheet, polyester sheet, nylon sheet, saran sheet, etc. are preferably used. Generally, a transparent synthetic resin sheet is used as having a thickness of 0.005 to 1 mm.

As the transparent synthetic resin sheet, an arbitrarily colored colored transparent synthetic resin sheet can be used. Alternatively, a colorless or colored transparent synthetic resin sheet having an arbitrary pattern printed on the back surface may be used. With this, in combination with the original surface design of the decorative veneer and the pattern pattern printed and formed on the surface, it is possible to emphasize the wood texture, express a new tree species, or express the depth. The designability as a single plate is further improved.

A decorative veneer having a transparent synthetic resin sheet placed on the upper surface thereof via an adhesive which becomes transparent or becomes transparent when cured is cold pressed, hot pressed, roll pressed,
The transparent synthetic resin sheet is adhered to the surface of the decorative veneer by pressing with a pressing device such as a laminator, wrapping, an edge pasting machine, or a vacuum press to form a surface protective layer.

The decorative veneer of the present invention is obtained as described above.

The decorative veneer of the present invention can be bonded to the surface of the substrate with an adhesive to form a decorative plate.

As the substrate, plywood, wood board, wood fiber board, wood shaving board, laminated wood, single board laminated board and the like are used alone or as a laminated board which is optionally laminated. In addition, the board is cut arbitrarily, and a skirting board, a rim, a molding, a door, a window on which the surface and the mouth end are optionally decorated by grooving or chamfering using a cutting machine such as a router or a cutter. It can also be used as a base material for face materials, sculpture materials, etc.

The adhesive is applied to the surface of the substrate by using a coating device such as a sprayer, a spreader or a bar coater. As this adhesive, a vinyl acetate resin-based, urea resin-based, melamine resin-based, phenol resin-based, isocyanate-based, etc. adhesive is used alone or as a mixed adhesive. If necessary, talc, calcium carbonate, clay, inorganic powder such as titanium white, wheat flour, wood powder, plastic powder, colorant, insect repellent, fungicide, etc. may be added to and mixed with the adhesive. . In general, the adhesive has a solid content of 35 to 80% and is applied to the surface of the substrate at a coating amount of 50 to 300 g / m ² .

A decorative veneer is adhered to the surface of a substrate via an adhesive, and as an alternative to or in addition to applying the adhesive to the surface of the substrate as described above, an optionally lined decorative veneer is used. You may apply an adhesive agent to the back surface of a board. The decorative veneer may be attached to each substrate, or may be continuously attached to a plurality of substrates.

In this way, the substrate on which the decorative veneer is placed on each leaf or continuously through the adhesive is cold pressed, hot pressed, roll pressed, laminator, wrapping, edge pasting machine, vacuum press. A decorative veneer can be obtained by adhering the decorative veneer to the surface of the substrate by pressing with a sticking device such as.
