Abstract

PURPOSE:To provide a finishing carpentry material high in productivity, and low in cost by using a medium quality fiber plate as a finishing carpentry base material since the finishing carpentry material is generally worked out of timber so as to be used in a bar shape, and the sawing pattern is difficult while expansion, contraction, twisting, cupping, cracking and the like due to moisture absorption and drying are generated. CONSTITUTION:A medium specific gravity fiber plate provided with a hard layer 2 high in specific gravity at least on its surface, is formed into a finishing carpentry base material of a specified shape 1. The entire surface of the finishing carpentry base material 1 which appears at the time of construction, is covered with an ornamental sheet shape material 3.

Detailed Description of the Invention

[0001]

[Industrial application] Artificial materials such as skirting boards, rims, doors, opening frames for windows, etc. with a decorative sheet attached to the surface.

2. Description of the Related Art Art work materials are generally used by processing wood, but since they are used in the shape of a bar, it is difficult to remove wood, and it absorbs moisture, expands and contracts due to drying, and further twists.
Warpage and cracks occur.

In order to prevent these expansion and contraction, wood is used as a core material, and a particle board made by sticking a flexible surface material such as paper, synthetic resin sheet or cloth on the surface around the core material. There is provided a decorative board made of plywood, which is V-grooved on its back surface and is bent and adhered. However, in this proposal, V-groove processing and bending adhesion have to be performed using a core material and a decorative plate, resulting in low productivity and high cost.

Further, the surface of a particle board or plywood is used as a substrate, and the surface thereof is optionally decorated. Then, a flexible surface material such as paper, synthetic resin sheet or cloth is attached to the decorative plate or substrate shown above. Since the surface of the particle board or plywood to be used is porous, it is necessary to apply a sealing process to obtain a smooth surface before attaching the surface material.

[0005]

[Technical Means] A medium specific gravity fiberboard provided with a hard layer 2 having a high specific gravity on at least the surface thereof is used as a work material base material 1 having a predetermined shape, and at the same time, the entire surface of the work material base material 1 which appears during construction is made up. Artificial material covered with sheet-like material 3.

[0006]

[Description of Configuration] A substrate 1 is a medium specific gravity fiber board having a hard layer 2 having a high specific gravity on at least the surface thereof. Medium specific gravity fiberboard has a specific gravity of 0.4 to 0.8, is lightweight and has good workability,
Excellent handleability. The hard layer having a high specific gravity exposed at least on the surface thereof is provided with a specific gravity of 0.8 to 1.5 and a thickness of about 0.3 to 5 mm. The hard layer 2 may be provided not only on the front surface but also on the front and back surfaces.

The medium specific gravity fiberboard is, for example, defibrated in the manufacturing process of the wood fiberboard by the dry method and added with an adhesive,
The dried wood fibers are deposited on a screen conveyor by a forming device, temporarily pressed to obtain a wood fiber mat, and then cut to a certain size to form a regular wood fiber mat, which is then heat pressed. Although it is obtained by increasing the amount of the adhesive added to the wood fiber in the above manufacturing process or increasing the water content of the wood fiber, the layer thickness of the hard layer on the front surface or the front and back surfaces is increased. It

Further, water is applied to the upper surface or the lower surface of the standard length wood fiber mat, or a water-retaining sheet-like material such as a non-woven fabric, paper or cloth is hydrated to the upper surface or the lower surface of the wood fiber mat. When it is placed and heated in this state, it is heated and clamped in a state where the water content of the front and back portions is increased, so that the layer thickness of the hard layer on the front surface or front and back surfaces is formed larger.

In this way, a medium specific gravity fiberboard having the hard layer 2 having a predetermined thickness on the surface is obtained. In the obtained medium specific gravity fiber board, a thin surface layer of low specific gravity is formed by precure of the adhesive at the time of heating and pressing, so at least the surface side is sanded to remove the low specific gravity thin surface layer and expose the hard layer. Let

The medium specific gravity fiberboard is cut into an arbitrary width and is decorated with chamfering, grooving, etc.
The work material base material has a predetermined shape such as a rim, an opening frame for a door or a window. An adhesive is applied to the entire surface of the surface, which appears during the construction, as a work material of a work material base material made of a medium-density fiber board with arbitrary decoration. The coated surface of the adhesive may be previously subjected to a sealer treatment or an undercoat treatment.

As the adhesive, a vinyl acetate resin type, a polyethylene resin type, an epoxy resin type, a urea resin type, a melanmine resin type, an acrylic resin, a phenol resin type, an isocyanate or the like may be used alone or in an arbitrary mixture or modified form. Also, the adhesive may be talc, charcoal,
Clay, titanium, inorganic powder such as metal powder, wheat flour, wood flour,
Plastic powder, colorants and natural essential oils, aromatics such as synthetic fragrances, deodorants, insect repellents, fungicides, pest repellents and the like may be mixed and used, and coloring, concealing effect, forest bath effect,
Aroma effect, deodorant effect, insect repellent effect, pest repellent effect, and antibacterial effect may be imparted. The agents are added and mixed directly or in the form of emulsion or microcapsule.

Next, the decorative sheet material 3 is placed and attached to the surface of the substrate 1 coated with the adhesive. The decorative sheet material 3 is a lumber board, an artificial lumber board, or a backing material of which Japanese paper, western paper, non-woven fabric, a garment cloth or the like is attached to the back surface, or the surface of which is arbitrarily colored, or a decorative paper or a cosmetic resin impregnation material. Paper, decorative synthetic resin sheet, film or the like is used.

The decorative sheet material is pressure-fitted by using a lapping device, a laminating device, or the like. The sticking of the sheet-like material to the construction material base material does not pose any problem even if it covers the entire surface of the construction material base material that appears during construction and even the construction material base material that shades during construction.

Further, grooves 4a, 4b are formed on the surface of the work material substrate 1.
In the case of engraving, the sheet-like material 3 may cover the entire front surface including the inside of the groove, or the sheet-like material 3 may cover the entire surface except the groove. The grooves are formed by forming grooves 4a and 4b on the prefabricated work material base material 1 and then forming the decorative sheet material 3
Alternatively, it may be formed by coating the decorative material substrate 1 with the decorative sheet material 3 and then engraving the grooves 4a and 4b.

In this way, the medium specific gravity fiberboard on which at least the hard layer 2 having a high specific gravity is provided on the surface is used as the work material base material 1 having a predetermined shape, and the surface of the work material base material 1 which appears during construction is shown. An artificial material having the entire surface covered with the decorative sheet material 3 was obtained. Since the hard layer 2 is provided on the surface, it is hard and hardly scratched as a work material.

Except when a medium specific gravity fiberboard is used as the work material base material 1, hard layers are formed on the front and back surfaces or the four peripheral surfaces of plywood, particle board, veneer laminate, flake board, strand board, veneer, and laminated wood. It is also possible to use the adhered medium specific gravity fiber board as a work material base material.

[0017]

Since the medium specific gravity fiber board having the hard layer 2 is used as the work material base material 1, the surface is not easily scratched.
