Abstract

The invention discloses anti-bacteria mouldproof putty powder and relates to the field of paints. The anti-bacteria mouldproof putty powder is prepared from 40-80 parts of modified talcum powder, 20-40 parts of kaolin powder, 5-10 parts of white cement, 10-15 parts of modified zeolite powder, 2-5 parts of octenyl succinic starch ester, 5-10 parts of silicon dioxide dihydrate, 1-2 parts of hydroxypropyl methyl cellulose, 0.1-0.7 part of aluminium-magnesium silicate and 0.5-1 part of pigment. Compared with the prior art, the anti-bacteria mouldproof putty powder disclosed by the invention has the advantages as follows: since octenyl succinic starch ester and silicon dioxide dihydrate are added into the putty powder, the putty powder has excellent bonding strength, and does not hollow, peel and crack after being exposed to water and affected with damp; meanwhile, modified zeolite powder is added into the putty powder, so that the anti-bacteria mouldproof functions of the putty powder are improved further; since the zeolite powder which can adsorb hazardous substance and moisture in air due to the own structure is added, the anti-bacteria mouldproof putty powder has the effects of purifying air and adjusting indoor air humidity, and can effectively reduce indoor formaldehyde content.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an antibacterial and antimildew putty powder. Background technique [0002] Putty is a kind of decorative coagulation material for leveling the surface of the wall. It is a thick paste paint and an indispensable product before painting. The purpose of applying putty is to fill the pores of the construction surface and correct the curve of the construction surface Therefore, the putty should have good adhesion and water resistance to ensure that there will be no peeling, hollowing and cracking under the long-term corrosion of water vapor in the air. Phenomena occur, play a decorative and protective role. [0003] However, existing putty powders have poor water resistance, easy peeling, hollowing and cracking under the long-term corrosion of water vapor in the air, and some are chemically unstable, easily corroded by acid and alkali, and mildewed.
