Problems solved by technology

The existing environment-friendly interior wall putty powder that does not contain 107 glue is usually composed of white gypsum powder, talcum powder, white powder, heavy calcium carbonate and other inorganic substances and cellulose, and is usually made of the viscosity of the above-mentioned inorganic materials or bentonite. As an adhesive material, when this environmentally friendly interior wall putty powder is used as an interior wall or ceiling, the hardness of the bottom surface of the scraped wall is low, making it difficult to calender the scraped wall, so the surface is not smooth and the water resistance is poor. , easy to slag, peel, and small cracks

Abstract

The invention discloses an environment-friendly water-resistant interior wall putty powder, which mainly comprises the following components by weight: heavy calcium carbonate powder 70-75, light calcium calcium powder 20-35, gray matter calcium powder 40-55, Alpha starch 15-20, carboxymethyl cellulose 18-25, water-soluble rubber powder 14-18. This environmentally friendly water-resistant interior wall putty powder has the advantages of strong water resistance, no slag, no peeling, and no cracks. The construction surface is smooth, easy to calender, not easy to mildew, and it is convenient for construction and low in cost.

Description

technical field [0001] The invention relates to a building material, in particular to a putty powder for interior walls. Background technique [0002] The current interior wall putty powder is mainly made of calcium calcium carbonate, talc powder, large white powder, white cement, 107 glue, etc., but because 107 glue contains toxic and volatile substances such as formaldehyde, it does not meet environmental protection requirements. The existing environment-friendly interior wall putty powder that does not contain 107 glue is usually composed of white gypsum powder, talcum powder, large white powder, heavy calcium carbonate and other inorganic substances and cellulose, and is usually made of the viscosity of the above-mentioned inorganic materials or bentonite. As an adhesive material, when this environmentally friendly interior wall putty powder is used as an interior wall or ceiling, the hardness of the bottom surface of the scraped wall is low, making it difficult to calen...
