Abstract

The invention discloses a putty powder and a preparation method thereof, belonging to the technical field of building materials. The putty powder comprises the following components in parts by weight: 200-500 parts of stone powder; 50-80 parts of sodium-based bentonite ; 5-20 parts of sodium alginate; 40-75 parts of starch; 15-65 parts of carboxymethyl cellulose; 10-100 parts of polyvinyl alcohol powder; 2-30 parts of calcium chloride powder; 15 parts borax. The method is to weigh each raw material, add each raw material except calcium chloride into water, mix evenly, take out and thaw after freezing, and then freeze after thawing, repeat the cycle several times, and thaw; soak the thawed mixture in chlorine Calcium solution, drying to obtain the putty powder. The invention can effectively improve the properties of crack resistance, hammer resistance, slip resistance and environmental protection of the putty powder for interior walls.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a putty powder and a preparation method thereof, which are widely used in infrastructure construction fields such as house walls, concrete walls, roofs, subway transportation, and large public buildings. Background technique [0002] Putty powder is a kind of building decoration material. It is a kind of base material used for wall repair and leveling, which lays a good foundation for the next decoration (painting / wallpapering). Putty is divided into two kinds: putty inside wall and putty on exterior wall. External wall putty can resist wind and sun, so it requires good gelation, high strength and low environmental index. The inner wall putty requires a good comprehensive index, which is healthy and environmentally friendly, 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 su...
