Preparation process of highlight BMC material

Abstract

The invention discloses a preparation process of a highlight BMC material. Coarse particles serve as a product framework, fine particles and fibers serve as supplementary gaps, resin is added for filling, coarse particles 100A serve as basic aggregate, and two groups of H-50, six groups of 15A and thirty-two groups of H-8 are combined to form a whole group of pellets; and according to the required material rigidity, about 14.5% by volume of short fibers are matched, and the composition comprises the following components in percentage by volume: 27.5% of resin and low shrinkage, 14.5% of fiber, 61.28% of aluminum powder filler and 6.8% of auxiliary additive. According to the invention, fine burdening, perfect kneading, unique mould pressing and careful B surface treatment are carried out through strict technical control, so that a beautiful sanitary appliance product is obtained; and the sanitary appliance product has the excellent characteristics of smooth surface, good glossiness, diversified colors, acid resistance, alkali resistance and stain resistance.

Description

technical field [0001] The invention relates to the technical field of sanitary ware composite materials, in particular to a preparation process of high-gloss BMC materials. Background technique [0002] The Chinese name of BMC composite material is bulk molding compound, and BMC is a molded intermediate material for semi-dry manufacturing of glass fiber reinforced thermosetting products. The main raw materials are composed of UP (unsaturated resin), low shrinkage additive, MD (filler), GF (special yarn) and various auxiliary agents. It first appeared in Europe in the early 1960s, and around 1965, the United States and Japan successively developed this craft. At the end of the 1980s, our country introduced foreign advanced SMC production lines and production processes. Nowadays, SMC and BMC composite products are common in the market. The advantages are high strength, water resistance, high temperature resistance and oil pollution resistance. [0003] However, the existing...

Problems solved by technology

[0004] The purpose of the present invention is to provide a preparation process for high-gloss BMC materials, which solves the problem that because BMC molded products are mainly industrial products, there is no requirement for high requirements on the surface (A side) of the product, so in the material In terms of formula, strength and hardness are the main assessment objectives. Now, for civil products that need to be made into sanitary ware, props, and panels, it is necessary to have extremely high requirements on the surface of the product (such as surface finish, stain resistance, chemical resistance, etc.)
