Description

The present invention relates to a decorative board in a veneer-bonded plywood and a manufacturing method thereof. More specifically, the present invention relates to a veneer engraving decorative board that is useful as a building material such as furniture, doors, wall surfaces, ceiling materials, etc., and has a good design and a deep texture, and a manufacturing method thereof. It is.

DESCRIPTION OF RELATED ART Conventionally, the decorative board which consists of various materials is known, and is widely used as building materials, such as furniture, a door, and a ceiling board. As one type of this decorative board, a brushed surface of wood is used to scrape the spring material portion and the flower pattern portion to form irregularities on the surface, followed by painting finish (see Patent Document 1). This decorative board is also attracting attention as a wooden material having an excellent texture as it makes use of the natural unevenness of the surface of the wooden material (see Patent Document 2). Furthermore, a decorative plate is provided by carving a pattern on a surface to which a veneer is bonded and injecting a pigment into it (see Patent Document 3).

For decorative panels such as furniture, the supply of natural wood, sculpture boards, etc., and the use of decorative boards made of various wood processing materials such as plywood printed on the surface of the resin or laminated materials, are becoming popular. Designability that cannot be expressed only with natural wood has become an important issue.
In order to cope with such problems, it has become common to apply a relatively thin veneer to the surface of a woody base material as a processed material to obtain a natural wood-like building material. However, in the case of such a veneer with a veneer, an ordinary thin 0,2 to 0,5 mm thick veneer is pasted on the base material as a processed material, and the surface portion is shaved to form irregularities on the surface. When trying to finish the coating, the projecting plate is partially scraped off during scraping and the base material is exposed in the recess. For this reason, it has been difficult to apply it to the production of a veneered decorative board that expresses unevenness by applying a sculpture shaving process and has almost no merit.

The realization of a method to make use of the unique texture of the surface, which cannot be expressed by surface processing such as brushing, on the veneered veneer is required. In view of the above circumstances, the present invention eliminates the drawbacks of the conventional brushing process, and by applying this engraving process to the veneer decorative plate, a new veneer sculpture that can form an excellent textured surface. It aims at providing a decorative board and its manufacturing method.

In the present invention, after pasting 2 to 5 veneers with different colors and patterns on a base material such as wood or metal, the surface layer portion is sequentially carved from the surface into a pattern state, and the interior of the carved concave portion is colored / patterned A veneer engraving decorative board to be used as a decorative board and its manufacturing method. In general, the thickness of the protruding plate is 0, 2 to 0.5 mm. In addition, wood of the veneer includes oak, tammo, maple and walnut.
2-5 veneer plates with different colors and patterns are alternately bonded to this base material, and carved into a specific pattern from the surface veneer in order. This is a method for producing a veneered engraved decorative board by making a board.

In the present invention, an adhesive for bonding 2 to 5 veneers on a wood, metal, or resin base material is a decorative material that uses aminoplast resin, vinyl resin, and synthetic rubber as an adhesive component. A method for producing a veneer engraving decorative board, which is a board, and examples of the adhesive component include aminoplast resin, vinyl resin, and synthetic rubber. Examples of the aminoplast resin include urea resin, melamine resin, urea-melamine cocondensation resin, urea-phenol cocondensation resin, and melamine-phenol cocondensation resin. Examples of the vinyl resin include vinyl acetate resin, ethylene-vinyl acetate copolymer resin, acrylic resin, vinyl acetate-acrylic copolymer resin, and styrene-acrylic copolymer resin. Examples of the synthetic rubber include a styrene-butadiene copolymer and an acrylic-styrene-butadiene copolymer. One of these may be contained, or two or more may be mixed and contained.

Different veneer colors, patterns and orientations, and the same two to five veneer laminates, veneer grain, and different types of materials as described above, or dark and bright material colors A veneer engraved decorative board, which is a decorative board in which the upper layer part is carved into a specific pattern state on the first to fifth sheets, and the base material is left as it is, and its manufacturing method is there. The carving is done using a special blade.
In the present invention, the surface engraving pattern is a regular or amorphous shape, such as grass, flower, circle, ellipse, triangle, square, rhombus, stripe, check, polka dot, letter, geometric pattern, etc. It is a decorative board carved in quadruple and quintuple.

In the present invention, it may be good that the base material is exposed, and after shaving, excellent texture and design by applying a conventional paint finish to the light and dark irregularities that appear due to the difference between the upper and lower materials And realize.

According to the present invention, there is provided a veneered engraved decorative board excellent in both design and texture due to pattern expression. The manufacturing method is also simple and economical.

Hereinafter, the manufacturing method of this veneer engraving decorative board will be described in more detail with reference to the attached drawings. 1 and FIG. 2 are veneer laminates, FIG. 3 is a sectional view, FIG. 4, FIG. 5, FIG. 6 and FIG. 7 are veneer engraving decorative panels, and FIG. 8 is in use (base material, veneer, processed pattern, etc.) Is an example). For example, as shown in FIG. 1, FIG. 2, FIG. 3, and FIG.
(A) First, as a type of veneer with a veneer, a veneer with 2 veneers (used with 0, 2 to 0, 5 mm per veneer) (2) on the substrate (1) Fig. 1 shows the result of pasting three different types of veneer on the base material (1) (using 0, 2 to 0, 5 mm of veneer per plate) as shown in Fig. 2. It was. When using two to five stacked veneer plates, the same material or different materials may be used one above the other, depending on whether they are laminated in different directions or in the same direction. Come different. As the base material (1), suitable materials such as conventionally known MDF, plywood, solid wood and other processed wood materials are used, and two veneer laminates (2) and three veneer laminates (3 ) Also used various veneer materials such as oak, tammo and walnut. For the pasting, aminoplast resin was used as an adhesive component. As a method of using the adhesive, it can be applied by a roller, and each protruding plate can be joined by flat plate pressing or vacuum press molding.

(B) Next, the two veneer laminates (2) or the three veneer laminates (3) are adhered to the base material, and then engraved from the surface of the veneer plate to bond the two veneer plates ( Carve out the surface of 2) and the three laminated veneers (3). Thereby, irregularities are formed on the surface of the protruding plate. By this engraving, a part of the two projecting plates (2) and a part of the three projecting plates (3) are scraped to expose the part of the triple projecting plate or the base material in the shaved recess. . A cross-sectional view (FIG. 3) and a decorative board (FIG. 4) of the bonded veneer are shown. In that case, a special blade was used to carve the surface veneer. Industrially, it can be done by mechanical engraving.

(C) Conventionally, since the exposure of the base material (1) in the concave portion was unavoidable, engraving could not be applied to the veneer plate material. In the present invention, the exposure of the base material (1) was not possible. The decorative plate can be processed without causing the substrate to be exposed, and the substrate (1) is also well exposed. After engraving, surface finishing can be performed by conventional coating methods such as oil application, polyurethane treatment, polyester treatment, and UV treatment.
