室内刮大白感观柔和、美观、造价低廉,在建筑内墙装饰中应用广泛,现有刮白粉因采用羧甲基纤维素作胶结材料,刮大白面层易开裂,潮湿后霉变,旧墙面复修后,面层开裂更为严重,影响建筑物的质量,且成本高。本技术的目的是提供一种能抗裂防霉亚光刮白粉及其生产工艺。化学成分是:大白粉、谷粉、短纤维、PT杀菌防霉剂、防老剂、硅酸钠、火碱,前5种物质的重量比是100∶1～8∶0.001～0.005∶0.001～0.005∶0.001～0.005,硅酸钠是前5种物质重量总和的10%～40%,火碱是前5种物质重量总和的1%～2%。生产工艺是:将大白粉、谷粉、短纤维、PT杀菌防 The interior is white, soft, beautiful, and inexpensive. It is widely used in interior wall decoration of buildings. The existing shaved powder uses carboxymethyl cellulose as the cementing material, it is easy to crack the large white surface layer, mold after damp, and the old wall After surface restoration, the cracking of the surface layer is more serious, affecting the quality of the building and the cost is high. The purpose of the present technology is to provide a crack-resistant, mildew-proof, matte whitening powder and a production process thereof. The chemical composition is: white powder, wheat flour, short fiber, PT bactericidal anti-mold agent, antioxidant, sodium silicate, and fiery alkali. The weight ratio of the first five substances is 100:1 to 8:0.001 to 0.005:0.001 to 0.005. : 0.001 to 0.005, sodium silicate is 10% to 40% of the sum of the weights of the first five substances, and firebase is 1% to 2% of the sum of the weights of the first five substances. The production process is: sterilization of large white powder, grain flour, short fibers and PT
