Problems solved by technology

At present, the waterproof, anti-mildew and anti-break effects of putty on the market have been significantly improved compared with before, but in seasons with a lot of rainfall (such as the rainy season in the south of the Yangtze River) or in areas with high air humidity and in indoor humid spaces ( Such as: basement, carport, etc.) and other environments, the putty layer on the indoor wall will still be affected by moisture, fall off and moldy

Abstract

The invention discloses moisture-proof and mildew-proof putty suitable for a humid environment. The moisture-proof and mildew-proof putty is characterized by comprising the following components in parts by weight: 20-40 parts of heavy calcium carbonate, 30-60 parts of ash calcium, 3-8 parts of a mildew-proof material, 3-8 parts of hydroxypropyl methyl cellulose, 7-15 parts of Wacker rubber powder, 1-6 parts of starch ether, 1-6 parts of a retarder and 2-8 parts of a lubricant, the putty has the advantages that the putty has good filling, leveling and anti-permeability properties, good water resistance and mildew resistance, free of pollution chemical components, harmless to human bodies after hard drying, stable in performance and capable of absorbing water vapor on the surface of a wall and preventing the wall from being damped, mildewed and cracked, a putty layer does not fall off no matter in humid or dry days, and the putty can be used for wall decoration. The paint is especially suitable for wall coating in a humid environment.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a moisture-proof and mildew-proof putty suitable for humid environments. Background technique [0002] Putty (filling mud) is a decorative material for leveling the surface of the wall. It is indispensable before the paint is painted. It is applied on the primer or directly on the object to remove the surface of the object to be painted. Spiky defects. At present, the waterproof, anti-mildew and anti-break effects of the putty on the market have been significantly improved compared with before, but in seasons with a lot of rainfall (such as the rainy season in the south of the Yangtze River) or in areas with high air humidity and in indoor humid spaces ( Such as: basement, carport, etc.) and other environments, the putty layer on the indoor wall surface will still be affected by moisture, fall off and moldy. Contents of the invention [0003] The technical problem ...
