JPS61153178A - Production of decorative laminate stuck with sliced sheet - Google Patents

Abstract

PURPOSE:To produce a decorative laminate which has the appearance stuck with thick veneer piece and is easy in the execution by butting and sticking the thick veneer piece wherein the peripheral parts are chamfered on a top surface of a substrate so that a required pattern is formed to make the decorative laminate and performing suitably a colored paint or the like on the surface thereof. CONSTITUTION:A thick veneer 4 piece wherein the peripheral parts are chamfered is butted and stuck on a top surface of a substrate 1 via an adhesive 2 so that a required pattern is formed to make a decorative laminate. A colored paint is primed on the surface of the decorative laminate and thereafter the colored paint of a flat part is scraped away so that the colored paint is allowed to remain in the grooves 5 formed by the butted parts of the thick veneer 4 and in the conduit groove of a sliced sheet and finally a transparent paint is top-coated on the surface of the decorative laminate. As a result, the decorative laminate enriched in such the stereoignostic feeling that a natural veneer piece is stuck on a pattern one sheet by one sheet can be produced inexpensively and the execution can be easily performed because the thick veneer is stuck on a large base sheet. The more stereoignostic feeling can be given on the decorative laminate since the recessed parts of the grooves are finished more thickly than the flat parts.

Description

[Detailed Description of the Invention] [Industrial Application Field 1] This invention is a composite decorative board that is used for construction on the floor of a house, etc.
The present invention relates to a method for manufacturing a veneer-attached decorative board that has grooves and depressions along the pattern formed by the veneer pieces adhered to the surface and has a rich wooden feel and three-dimensional effect.

[Conventional technology] Wood composite decorative laminates made of plywood or other substrates have been widely used as flooring and wall materials for houses. Decorative materials that utilize a top coat of paint to bring out the wood grain, decorative materials that utilize a foamed vinyl chloride decorative sheet with cushioning properties attached to a substrate to make it feel soft, and various abstract patterns that are attached to a substrate. The decorative material was a decorative material that took advantage of the printed pattern, in which a transparent top coat was applied either smoothly or unevenly to the top surface of the decorative board printed with .

[Problems to be solved by the invention] Each of the various decorative materials mentioned above has its own unique look and feel, but with the diversification and luxury of housing, there are There are also many construction methods in which veneer pieces are combined to form various patterns and pasted one by one to the base material, similar to pasting tiles. However, compared to flooring or plywood-based wood composite decorative boards, veneer pieces are more expensive due to the depletion of wood, and the construction is complicated as the veneer pieces are pasted one by one, and it is difficult to install them using adhesives. Because it was constructed on-site, it could not be done by a carpenter, so it was not versatile.

Accordingly, the present invention relates to a method for manufacturing a decorative board pasted with veneer, which is easy to construct and has the appearance and feel of thick veneer pieces pasted thereon.

[Means for Solving the Problems] In order to achieve the above object, the present invention uses adhesive to form a thick piece of veneer on the upper surface of the board, the peripheral part of which is chamfered, to form a desired pattern. After the veneer is pasted and used as a decorative veneer, the surface of the veneer is coated with colored paint, and then when thick veneer is attached, the colored paint is left in the grooves formed by the veneer and the conduit grooves of the veneer. The present invention relates to a method for manufacturing a veneered decorative board, which comprises: first scraping off the colored paint on the flat parts, and finally overcoating the surface of the decorative board with a transparent paint.

Hereinafter, the present invention will be explained in detail with reference to the drawings. Fig. 1 is a perspective view of a veneered decorative floorboard according to an embodiment of the present invention, Fig. 2 is a sectional view taken along line A-A', Fig. 3 is a sectional view of another embodiment, and Fig. 4 is a sectional view of this decorative floorboard. It is an example side view schematic diagram showing the manufacturing process of a board.

The substrate (1) is plywood, hardboard, MDF, etc., and in this embodiment, actual processing is performed on the four peripheries.

Thick veneer to be pasted (0 is a hard veneer with clear wood grain such as zelkova, oak, sen, shioji, etc. with a thickness of 2.51111 or more, or the above hard veneer with a thickness of 2.5 m + W or less) A backing material (3) made of plywood or thick veneer is attached via an adhesive (2), and the material is cut into approximately rectangular, trapezoidal, triangular, etc. shapes depending on the desired pattern.

In addition, the thick veneer (4) pieces are chamfered in the shape of half of the groove so that when they are joined together using a cutting machine such as a cutter, a groove is formed on the side between the butt joints, and the thickness is cut as necessary. Single board (4
) Grooves with the same shape as the grooves are also made on the inner side of the river.

Groove shapes include U-groove, ■-groove, square groove, etc.

The adhesive (2) for attaching the thick veneer (4) to the top surface of the substrate (1) may be a commonly used vinyl acetate resin emulsion type adhesive, urea resin type, melamine resin type, phenol resin type adhesive, Apply adhesive (2) to the top surface of the board (1) using a coating machine such as a roller spreader with a rubber-based adhesive.
Thick veneers (4) are arranged thereon to form a unique pattern as shown in FIG. 1, and heat-pressed and bonded using a pressing machine such as a hot press. Next, after polishing the surface of this decorative board (6) with a sander or the like, the entire surface is coated with a colored paint (8).

As the coloring paint (8), use a commonly used opaque coloring paint such as lacquer, polyester, polyurethane, amino alkyd, etc., and apply it with a roller coater or sponge roller coater. Next, to emphasize the wood grain pattern, use a reverse coater or cloth puff roller. The colored paint (8) is left in the groove recesses (5) and the conduit grooves, and at the same time, the colored paint (8) on the flat parts is scraped off and dried. The purpose of applying the above wiping color to the decorative board (8) is to emphasize the wood texture.
This is to make the wood grain pattern and the veneer piece look more three-dimensional by finishing the groove recesses (5) and the vessel grooves darker than the flat areas.

Finally, the decorative board (6) and the regular transparent paint (11) on the entire surface.
Apply a topcoat and let dry.

As the transparent paint (11), a commonly used transparent paint such as lacquer, polyester, polyurethane, amino alkyd, etc. is used, and this is applied using a roll coater, curtain coater, or the like.

[Example] Next, embodiments of this invention will be described.

Apply 80 to 120 g of vinyl acetate resin emulsion type adhesive to the surface of the plywood with a thickness of 12 s + m, width of 30.3 cm, and length of 180 cm, which has undergone real processing around the four sides.
