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.

Description

technical field [0001] The invention belongs to the technical field of building material preparation, and in particular relates to a method for preparing a decorative plate. Background technique [0002] With the development of society and the improvement of people's living standards, people have higher and higher requirements for the aesthetics and functionality of house interior decoration and furniture. Among them, the beauty of interior wall panels and floors is crucial to the overall interior decoration effect. The decorative characteristics of the surface decoration materials used in the interior decoration process not only determine the aesthetics of the furniture, but also have an important impact on the decorative effect of the entire indoor environment where the furniture is placed. [0003] At present, there are various styles of boards suitable for interior decoration and furniture making on the market. Among them, the original or refined solid wood boards are n...
