Preparation method of decorative plate

Abstract

The invention belongs to the technical field of building material preparation, and particularly relates to a preparation method of a decorative plate. The preparation method comprises the following steps: emulsifying white mineral oil, mixing the emulsified white mineral oil with emulsified acrylic acid, mixing thermoplastic resin, modified emulsion, fiber pulp, flame-retardant filler and desulfurized gypsum powder, and preheating to finally obtain the composite decorative plate. The flame-retardant filler is filled into wood pulp fibers by a method of adding the flame-retardant filler into the pulp, and the main component of diatomite is silicon dioxide, so that the fireproof performance is improved; pores of the diatomite in the flame-retardant filler are filled with a large amount of ammonium polyphosphate, so that gas-phase combustion is inhibited, and the flame-retardant and fireproof performance of the decorative plate is improved; the surfactant emulsion is used, so that the moisture resistance of the decorative plate is enhanced; the decorative plate takes resin glue as impregnation, so that the fireproof performance is high; the decorative plate is directly decomposed andsublimated under a high-temperature condition, and a large amount of smoke is not generated during combustion; the main part of white mineral oil is of a straight-chain alkane structure, so that the waterproof performance is improved; the decorative plate has lasting moisture resistance and a wide application prospect.
