Abstract

The invention provides a water-resistant putty powder and a preparation method thereof, belonging to the field of fillers for coatings. Composed of the following components according to the following weight fractions: 35-50 parts of kaolin powder, 5-7 parts of montmorillonite, 2-5 parts of hydroxypropyl methylcellulose, 0.1-0.7 parts of polyacrylamide, 7-10 parts of titanium dioxide , 1-3 parts of polydimethylsiloxane, 13-17 parts of sepiolite powder, 0.3-7 parts of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate. The putty powder provided by the invention has high water resistance, acid and alkali corrosion resistance, resistance to cold and hot temperature changes, and high bonding strength. The invention is safe and healthy, the material is easy to obtain, and the cost is low, and the preparation method is simple.

Description

technical field [0001] The invention belongs to the field of fillers for coatings, and in particular relates to a water-resistant putty powder and a preparation method thereof. Background technique [0002] The main purpose of water-resistant putty powder is to fill the pores of the construction surface and correct the curve deviation of the construction surface, laying a good foundation for obtaining a uniform and smooth paint surface. Water-resistant putty powder, as one of the categories, is mainly used on walls or surfaces that require waterproofing. Water resistance and high bonding strength are required to ensure that under the long-term erosion of water vapor in the air, there will be no hollowing, peeling, cracking, etc., and it can still be tightly combined with the substrate and not easy to fall off. If it is used as a relocation coating, acid and alkali resistance is also required, and the temperature tolerance range is large. At present, the water resistance,...
