Weather resistant exterior wall putty powder

Abstract

The invention discloses weather resistant exterior wall putty powder which is prepared from the following raw materials: by weight, 20-30 parts of ash calcium powder, 10-20 parts of black cement, 10-15 parts of light calcium powder, 5-10 parts of white cement, 40-50 parts of modified talc powder, 1- 2 parts of carboxymethyl cellulose, 0.5-1 part of hydroxypropyl starch ether, 2-3 parts of redispersible latex powder, 1-2 parts of NSJF-11B latex powder, 0.5-1 part of rock cotton fiber, 0.4-0.6 part of carbon fiber yarn, 1.5-2 parts of NSJF-2A latex powder and 0.5-1 part of HS-2 moisturizing lubricant. The weather resistant exterior wall putty powder is not affected by wet and dry climates of regions, especially suitable for regions with large temperature differences, can withstand a long time test of the wet and dry climates comprising minus 30 DEG C severe cold in winter in the north and 40 DEG C high temperature in summer in the south, may not mutate, still has very good adhesion strength, and is durable in use, non-delaminating, non-peeling and non-pulverizing.

Description

technical field [0001] The invention relates to a weather-resistant exterior wall putty powder, which belongs to the technical field of building materials. Background technique [0002] The exterior wall putty powder is made of inorganic gelling material as the base material, and finely processed with bonding materials and other additives. Its outstanding features are high bonding strength, water resistance, alkali resistance and good construction performance. As a leveling material on the surface of outdoor buildings, it can be done once and for all, avoiding the occurrence of cracking, foaming, pulverization and falling off. It is widely used in cement walls, concrete walls, mosaic walls, tile walls, etc., but now Some putty powders also have the disadvantage of poor weather resistance, which cannot be used in areas with obvious dry and wet climates. Contents of the invention [0003] The object of the present invention is to provide a kind of exterior wall putty powde...
