Abstract

The invention discloses a water washing resistant putty powder for interior wall emulsion paint, and the water washing resistant putty powder comprises the following raw materials: by weight, 40-50 parts of calcium carbonate powder, 50-60 parts of modified talcum powder, 20-30 parts of ash calcium powder, 10-15 parts of white cement, 2.5-3.5 parts of hydroxypropyl methylcellulose, 3-5 parts of hydroxypropyl starch ether, 0.5-1 part of HS-2 moisturizing lubricant and 2-3 parts of NSJF-6 A emulsion powder. The putty powder has excellent water washing resistance and high bonding strength, when the putty powder meets water and is affected with damp, the putty powder may not fall off powder, pulverize, hollow and crack, is excellent in construction property, non-material-throwing and non curling, and has the advantages of being high in hardness, fast in film forming, moisturizing, mildew and damp proof, aging resistant, long in storage time, convenient to use, stable in performance and the like.

Description

technical field [0001] The invention relates to a washable putty powder for interior wall latex paint, which belongs to the technical field of building materials. Background technique [0002] Putty powder is a kind of decorative material for leveling the surface of the wall. It is made of inorganic gelling material as the base material and finely processed with bonding materials and other additives. It is an indispensable product before painting. Apply on the primer or directly on the object to remove uneven defects on the surface of the object to be coated. Putty powder is widely used as interior wall filling material. However, the existing putty powder for interior wall latex paint has the disadvantage of poor washing resistance, which leads to pulverization in subsequent construction. Contents of the invention [0003] The object of the present invention is to provide a kind of washable putty powder for interior wall latex paint in view of the deficiencies in the pri...
