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 earnest efforts to achieve such an object, has a colored coating applied to the surface of the decorative veneer, and the upper surface thereof becomes transparent or transparent when cured. A transparent synthetic resin sheet having surface recesses is adhered via an adhesive to form a surface protective layer having surface recesses.

Further, the method for producing a decorative veneer according to the present invention is characterized in that the surface of the decorative veneer is colored and the adhesive is transparent or cured on the colored coated surface of the decorative veneer. A transparent synthetic resin sheet having a surface recess is placed and pressure-bonded via the above to form a surface protective layer having a surface recess made 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.

Color coating is applied to the surface of the decorative veneer. Colored coating is generally performed on the surface of the decorative veneer using a sealer coating, sanding, etc., if necessary, and then coated with a colored coating using a coating device, and immediately sponge roll,
It is carried out by smoothing and rubbing the paint using a brush roll, a wool roll or the like. In addition, the excess paint is removed by using a reverse roll if necessary. By applying the colored coating, the color of the surface of the decorative veneer is unified, the wood grain, the conduit groove, etc. are remarkably exposed, and the design is improved.

After the colored coating is applied, an arbitrary pattern such as a grain pattern, a conduit groove pattern, an abstract pattern or a mosaic pattern can be formed by printing on the colored coated surface. The print formation of the pattern is performed by using any printing method such as letterpress, intaglio, gravure, gravure offset, silk screen, and transfer.

An adhesive that is transparent or becomes transparent when cured is applied on the colored coated surface of a decorative veneer by using an application device such as a sprayer, a spreader, a flow coater, a curtain coater, or a bar coater, and then a surface recess is formed. A transparent synthetic resin sheet having is placed.

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. Since this adhesive itself is transparent, or at least becomes transparent when cured, it is exposed without hiding the surface of the decorative veneer.

As the transparent synthetic resin sheet, polyethylene sheet, cellophane, acetate sheet, polyvinyl chloride sheet, polypropylene sheet, polystyrene sheet, polyester sheet, nylon sheet, saran sheet, acrylic sheet and the like are preferably used. Moreover, you may use what coat | covered these sheets with the heat adhesive resin. Generally, a transparent synthetic resin sheet is 0.005-1
Used as having a thickness of mm. The transparent synthetic resin sheet is placed on the colored coated surface of the decorative veneer for each decorative veneer or continuously for a plurality of decorative veneers.

The transparent synthetic resin sheet used in the present invention has a recess on its surface. By embossing the above-mentioned sheet material with an embossing board, an embossing roll, a wire brush, a sander, etc. ,
A recess is formed in the surface. The surface recess of the transparent synthetic resin sheet is a pseudo representation of a recess such as a conduit groove, a hairline, and a wormhole of a natural wood material, and the wood texture is emphasized by the shadow hardening by the recess.

Further, when the transparent synthetic resin sheet is attached to the colored coated surface of the decorative veneer, since an adhesive that is transparent or becomes transparent when cured is used, a recess such as a conduit groove on the surface of the decorative veneer may be formed. Since it is exposed from the surface through the transparent adhesive layer, the recesses that the decorative veneer itself has and the recesses that are artificially formed on the surface of the transparent synthetic resin sheet are combined, which is extremely characteristic. It is possible to exhibit excellent design characteristics.

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. This makes it possible to emphasize the wood texture, express a new tree species, or express the depth, in combination with the original surface design of the decorative veneer and the colored coating applied to the surface.

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

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

Further, after applying the colored paint to the general surface of the decorative veneer using the above-mentioned coating device, preferably immediately after that, using a reverse roll coater, the surface recess of the surface protective layer is formed. By removing the colored paint applied to the removed surface portion and leaving the colored paint only in the surface recesses, the surface recesses of the surface protective layer can be colored. As a result, the surface recess of the surface protective layer is more emphasized and the design is improved.

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 or the like is used alone or as a laminated board formed by arbitrarily laminating. 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 adhesive or the like 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. Instead of applying the adhesive to the surface of the substrate as described above, or together with this, 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. The decorative veneer is obtained by pressing the decorative veneer on the surface of the substrate using a sticking device such as the above.

[0027]

The surface protective layer is formed by using a transparent synthetic resin sheet and adhering it onto the colored coated surface of the decorative veneer surface via an adhesive which becomes transparent when it is transparent or cured. The surface protective layer corresponds to the thickness of the transparent synthetic resin sheet used and is formed to have a uniform thickness.

Since a surface recess is formed by embossing on the surface of the transparent synthetic resin sheet and the surface recess is exposed on the surface of the surface protective layer in the decorative veneer, it is applied to the surface of the decorative veneer. Combined with the colored coating, the design is improved.
