Problems solved by technology

[0003] The content of harmful substances such as benzene in this kind of putty is relatively high, and when the indoor air humidity is high, the wall will become moldy and cause spots; at present, people have higher and higher requirements for the comfort and environmental protection of the living environment and office environment. The use of putty is also gradually limited, so there is still room for improvement

Abstract

The invention relates to benzene-free mildew-proof putty for an interior wall. The putty comprises the following raw materials in parts by weight: 60-90 parts of ground calcium carbonate; 8-15 parts of ash calcium; 20-40 parts of light calcium carbonate; 0.3-0.6 part of hydroxypropyl methyl cellulose; 0.3-0.6 part of starch ether; 0.1-0.3 part of latex powder; 0.3-0.8 part of an alkali resistant agent; and 2-3 parts of mildew preventive. According to the putty, the heavy calcium carbonate, the ash calcium and the light calcium carbonate are used as raw materials of the putty; the starch etherand the latex powder enable the putty to have good coating uniformity and viscosity stability; the hydroxypropyl methyl cellulose has the characteristics of thickening, dispersing, adsorbing, keepingmoisture, protecting colloid and the like, so that the surface of the putty is fully hardened and smooth; the alkali resistant agent can effectively relieve the efflorescence phenomenon on the surfaceof concrete, and assists in improving the mechanical properties of the putty; and the addition of the mildew preventive improves a mildew prevention effect.

Description

technical field [0001] The application relates to a putty, in particular to a benzene-free and anti-mildew putty for interior walls. Background technique [0002] Putty is a decorative raw material used in decoration to level the surface of the wall. Traditional interior wall putty is usually made of talcum powder, construction glue and clear water. Professional workers at the construction site will mix it mechanically or manually before it can be applied to the base layer of the wall. [0003] The content of harmful substances such as benzene in this kind of putty is relatively high, and when the indoor air humidity is high, the wall will become moldy and cause spots; at present, people have higher and higher requirements for the comfort and environmental protection of the living environment and office environment. The scope of use of putty is also gradually limited, so there is still room for improvement. Contents of the invention [0004] In order to improve the anti-m...
