いわゆる異形の化粧板の提供が要望されてきている。2. Description of the Related Art Conventionally, decorative boards are rich in designability, weather resistance,
Heat resistance, abrasion resistance, and stain resistance can be easily imparted, so that it is widely used for housing members and construction panels. Particularly, in recent years, a high degree of designability has been required for housing members and building panels, and accordingly, it has been demanded to provide a so-called deformed decorative plate having a curved surface.

ている。As an example of a method for manufacturing such a modified decorative board, a plastic board material (for example, a high-pressure melamine board, a vinyl chloride resin board, an acrylic resin board, etc.) that has been heat-softened to a base material that has been curved in advance by an NC router or the like is used. ) Is adhered via an adhesive, a post-form processing method is adopted.

クが発生することがあった。However, in this case, since the heat-softened plastic plate material is heated and thermally expanded, when the plastic plate material is adhered in that state and then cooled, the plastic plate material contracts and reversely contracts with the base material. There was a case where dimensional difference occurred and warpage and cracks occurred.

る。According to the present invention, in a method for producing a composite decorative board by laminating a plastic plate material on the surface and the side surface of a base material, first, the plastic plate material is thermally softened to form the base material. A method for manufacturing a modified composite decorative board is provided, which comprises molding into a shape that fits into a material, then cooling and then mating and laminating with an adhesive, wherein the plastic board material is an acrylic artificial marble. There is provided a method for producing the odd-shaped composite decorative board.

Alternatively, bending or compressive stress is applied until the curved surface fits into the curved surface of the mold. The heating temperature of the plastic plate material 3 varies depending on the material and the degree of cross-linking, but it is desirable that the curved surface part is not whitened or cracked. Generally, the heating temperature of the plastic plate material 3 is higher than the glass transition temperature of the plastic plate material 3. It is desirable to heat to a temperature 10-30 ° C higher. Further, far infrared rays, high frequency waves, hot air, etc. can be used as the heating means.

ー、扉、建築用パネル等に有用なものである。[Effect] According to the present invention, since a plastic plate having a thickness of 1 to 3 mm is used as the decorative material, it has a deep designability. Furthermore, since the base material and the plastic plate material are adhered to each other at around room temperature, warpage and cracks after the composite are less likely to occur, and the adhesion is good, so that the physical strength is also excellent. In particular, when acrylic artificial marble is used as the plastic plate material, it is possible to obtain a beautiful deformed composite decorative board that has the same level of design as conventional thick artificial marble, yet is lightweight and easy to handle. Therefore, such a deformed composite decorative board is useful as a top plate for home parts, furniture, counters, doors, building panels, and the like.
