Problems solved by technology

[0002] At present, most of the decorative materials are made of wood base material with decorative paper or paint finish. As an emerging industry, the overall bathroom uses composite materials to replace wood base material, marble, etc. The existing SMC wall panels for the overall bathroom, in order to achieve surface Beautiful, through integral molding of SMC substrate surface and decorative paper, it solves the problem of monotonous color before, but there are still defects such as the surface is not bright enough, not full, not wear-resistant, easy to scratch when using; the overall bathroom uses VCM board wall The surface is color steel plate, which solves the aesthetic problem of the surface of the overall bathroom wall panel, but the surface is prone to pits, the transportation and installation process is very demanding, and the cost is very high

Abstract

The invention discloses a wallboard for an integral bath room and a preparation method of the wallboard. A substrate is an SMC sheet-shaped molding compound molded plate, a panel is a glue film veneered thin aluminum plate, and the glue film veneered thin aluminum plate is obtained by compounding a glue film and a thin aluminum plate through film laminating. The preparation method of the wallboard comprises the following steps: compounding the glue film with the aluminum plate to obtain a panel material; and paving the panel material on the surface of a mold, feeding the substrate into the mold, laminating the substrate to the back of the panel material, heating the panel material and the substrate to 125-145 DEG C, and carrying out once pressure forming in the mold, wherein the front surface of the panel material faces to the mold. A polyurethane hot melt adhesive is utilized, when the temperature is 100-120 DEG C, isocyanate groups of polyurethane are maintained at a closed state, when the temperature is 125-145 DEG C during in-mold forming, double bonds of isocyanate are opened at about 130 DEG C and are bonded with hydroxyl groups in SMC sheets, and then the thin aluminum plate and the SMC substrate are firmly bonded together through polyurethane glue. The wallboard has excellent metal texture, is plump and wear resistant and is unlikely to be scratched.
