Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a decorative board that is used by applying it to a floor material of a house, and more specifically, a decorative board formed by a projection of a veneer piece attached to the surface. The present invention relates to a veneer with a veneer that has a groove-like recess and is rich in wood texture and three-dimensional.

[Prior Art] Wooden decorative boards using plywood as a substrate are widely used as flooring and wall materials in homes.
Stick a thin veneer of about 0.5 mm on a checkered pattern, a small checkered pattern, or a random pattern, and apply a top coat paint on the surface to make use of the grain of wood or a plywood board. There is a decorative plate in which a plurality of plates are adhered in parallel, a groove having a depth reaching the substrate is formed along the joint portion of the single plate, and the surface is similarly coated with a top coat.

[Problems to be solved by the invention] However, in the above decorative plate, a thin single plate is attached to the substrate, so that the three-dimensional effect is poor, and in the case of a grooved decorative plate, especially in the case of a plywood substrate, inside the groove In addition, there is a problem in that the cut fibers of the plywood substrate are fluffed and the finish is poor.

It is an object of the present invention to provide a veneer-attached decorative plate which is rich in three-dimensional appearance and has a good-looking wooden texture without the substrate being exposed inside the groove formed on the surface of the decorative plate.

[Means for Solving the Problem] The problem is that a backing material is attached to the upper surface of a rectangular substrate having a dimension of about 30 cm or more on one side, and a chamfered veneer piece is adhered to the periphery with an adhesive. A veneer-attached decorative plate is characterized in that a plurality of pieces are attached by butt-bonding so as to form a pattern, and a groove-shaped concave portion in which the backing material is not exposed is formed in the butt portion.

[Example] FIG. 1 is a perspective view of a veneer-coated veneer, and FIG.
It is an A'cross section figure.

Substrate 1 is made of wood such as rectangular plywood with a side of about 30 cm (about 1 shaku) or more, hardboard, particle board, medium density fiberboard, etc., usually 30.3 cm × 182 cm, or 30.3 cm × 91 cm.
Something of a size is used. Actual processing is performed around the four areas to improve workability.

The backing material 3 is made of laminated veneer material, medium specific gravity fiberboard, hard board, plywood or thick veneer and has a thickness of 2.5 m.
It is cut into a substantially rectangular shape, a trapezoidal shape, a triangular shape or the like depending on the desired pattern with a length of m or more, preferably 3 mm or more.

The veneer piece 4 is a hard veneer with a sharp wood grain of 2.5 mm or less in thickness such as zelkova, oak, sen, shioji, etc., and is attached to the back side to prevent chipping of the veneer piece during chamfering and grooving. The above-mentioned backing material 3 is previously attached via an adhesive. The veneer piece 4 is chamfered on its peripheral portion so that the groove-shaped recess 5 is formed at the butt when the ends are abutted by a cutting machine such as a cutter. Grooves having the same shape as the groove-shaped recesses 5 are also formed inside the plate piece 4 to a depth that does not cut the single plate.

As the adhesive 2 for sticking the single plate piece 4 to which the backing material 3 is stuck to the surface of the substrate 1, vinyl acetate resin emulsion type, urea resin type, melamine resin type, phenol resin type, rubber type, etc. Then, using a coating machine such as a roller spreader, the coating is applied on the substrate 1, and a plurality of single plate pieces 4 are abutted on each other so as to form a unique pattern as shown in FIG. It is heated and stuck by a pressing device such as.

The colored paint may be applied so as to remain in the groove-shaped recess 5 formed by the abutting portions of the single plate pieces 4 on the surface of the decorative plate 6 or the conduit groove on the surface of the single plate piece 4. As the colored paint, a commonly used colored opaque or colored transparent paint such as lacquer, polyester, polyurethane, amino alkyd, etc. is used. At the same time, it is applied by an operation such as scraping off the colored paint on the flat portion. When the coloring paint is applied in this way, the groove-shaped recess 5 and the conduit groove are finished in a darker color than the flat portion, and the wood texture and three-dimensionality of the decorative board are further emphasized. Then, if necessary, a regular transparent paint layer is formed on the entire surface of the decorative plate 6.

[Advantage of the Invention] Since the veneer-attached decorative plate of the present invention has the above-described structure, the color and material of the backing material and the substrate do not directly appear inside the groove on the surface of the decorative plate, and a beautiful groove is formed. In addition to obtaining a decorative surface having concave portions, a backing material is attached to the back surface of the veneer piece, so that it is possible to prevent chipping of the end of the veneer piece during chamfering.
