Its composition includes (wt%) 10-13% of soft water, 0.2-0.3% of methyl cellulose, 0.1-0.2% of lithium mineral thickening agent, 0.3-0.5% of polycarboxyamine salt, 10-15% of silicon acrylic latex, 0.3-0.5% of wax emulsion, 0.1-0.2% of high-viscosity modifying agent, 0.5-1% of glycol, 0.5-0.7% of 12C ester alcohol, 1-5% of zinc stearate, 0.1-0.3% of defoaming agent, 30-40% of coarse whiting with 200 meshes and 25-35% of talcum powder with 400 meshes.

Description

technical field [0001] The invention relates to a paint putty for coating exterior walls, in particular to a paint putty capable of preventing cracking, efflorescence, staining, discoloration and falling off of paint applied on cement walls and concrete walls. Background technique [0002] Paint is usually applied on the base surface of the building wall. The purpose of applying exterior wall paint is to cover up the defects of the base surface of the wall, and to protect the wall to a certain extent, to protect the steel from corrosion, and to protect the concrete from carbonization. Chlorinated, not affected by mold and algae. But because there are various defects in the base surface of the building wall, it is necessary to smear one deck of putty before painting. However, cracking, pan-alkali, discoloration, staining, and shedding are common phenomena in the current exterior wall coatings during use. Inelastic and water-resistant, it is easy to cause the exterior wall c...
