Abstract

The invention discloses mildew-proof formaldehyde-free benzene-free putty powder. The mildew-proof formaldehyde-free benzene-free putty powder is prepared from the following raw materials in parts byweight: 6 to 8 Kg of pre-gelatinized cassava, 0.3 to 0.5 Kg of citric acid, 0.5 to 0.8 Kg of a cream dispersing agent, 10 to 12 Kg of carboxymethyl CMC, 12 to 20 Kg of bentonite and 950 to 1000 Kg oftalcum powder. The putty powder is formaldehyde-free, benzene-free, VOC-free, odorless, healthy and environment-friendly, and is high in comprehensive index and particularly suitable for interior wallspace decoration.

Description

technical field [0001] The invention relates to a mildew-proof, formaldehyde-free and benzene-free putty powder. Background technique [0002] Putty powder is a kind of building decoration material, the main components are talcum powder and glue. A layer of white putty on the surface of the rough room just purchased. Putty is a kind of base material for leveling the wall, which lays a good foundation for future decoration (painting and wallpaper). Putty is divided into two kinds: putty inside wall and putty on exterior wall. External wall putty can resist wind and sun, so it has good gelation, high strength and low environmental index. However, the comprehensive index of putty on the inner wall is better, and it requires health and environmental protection, so the inner wall is not for external use, and the outer wall is not for internal use. Putties are usually based on gypsum or cement, so rough surfaces are easier to bond firmly. However, during construction, it is st...
