Waste red brick powder-based mineral polymer inorganic dry powder texture coating material and preparation method thereof

The invention discloses a waste red brick powder-based mineral polymer inorganic dry powder texture coating material and a preparation method thereof. The preparation method comprises: adding 40-85 parts by weight of waste red brick powder, 15-30 parts by weight of metakaolin, 20-35 parts by weight of blast furnace slag powder, 1-3 parts by weight of natural zeolite powder, 0.5-1 part by weight ofnano silicon dioxide, 0.3-0.5 part by weight of nano aluminum oxide, 2-5 parts by weight of hollow micro-beads, 1-2 parts by weight of redispersible latex powder, 0.1-0.2 part by weight of polyvinylalcohol short fibers, 1-2 parts by weight of nano attapulgite powder, 15-40 parts by weight of powdery sodium silicate, 2-5 parts by weight of ash calcium and 0-5 parts by weight of an inorganic pigment into a dry powder mixer, stirring for 20 minutes, packaging the uniformly stirred powder, and sealing to obtain the dry powder coating material. The coating material is healthy, environment-friendly, free of caking, high in
