Abstract

The invention discloses a preparation method of environmentally-friendly interior wall putty powder. The preparation method comprises the following steps: S1. performing gelatinization treatment on cassava starch through a conventional method to obtain gelatinized cassava starch for future use, and treating calcium bentonite through sodium carbonate to obtain sodium bentonite for future use; S2. putting the following ingredients into a diffuser provided with a stirrer: 15-18 parts of white cement, 3-5 parts of sierozem powder, 6-8 parts of gelatinized cassava starch, 22-26 parts of heavy calcium carbonate powder (320 meshes), 3-5 parts of expanded perlite (200 meshes), 1.5-2.5 parts of polypropylene fiber (3-5mm), 2-4 parts of polyvinyl alcohol, 2-3 parts of sodium carboxymethyl cellulose, 2.5-3.5 parts of three-grade fly ash, 5-7 parts of sodium bentonite and 1-2 parts of sodium fluosilicate, and stirring the ingredients for 10-20 minutes; and S3. adding 2-4 parts of dispersing agent, 0.4-0.6 parts of antifoaming agent and 0.2-0.4 parts of parts of mildew preventive, and stirring for 30-40 minutes. The putty prepared by the preparation method disclosed by the invention is anti-cracking, free of peeling, dropping and toxic and harmful substances and is capable of properly perfecting the environmental quality.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a preparation method of green and environment-friendly interior wall putty powder. Background technique [0002] The structure of modern buildings is an organic whole, load-bearing walls, functional insulation layers, waterproof layers, decorative layers, materials at all levels complement each other and are indispensable. Putty is located between the wall leveling mortar and the paint layer, and plays an auxiliary role in further leveling and forming decorative texture patterns. The putty powder is convenient for packaging, storage and transportation, and it can be directly applied by adding water and stirring evenly on site. Common putty powders on the market are mainly composed of white cement, inert fillers, and chemical additives, which are obtained by uniform mixing. After this dry powder material is transported to the construction site, it can be scraped and ap...
