Abstract

The invention discloses a nano organosilicone exterior wall paint, which is characterized in that the wall paint consists of the following materials in weight percentage: 20 to 28 percent of clean tap water, 0.8 to 1.3 percent of dispersant, 0.2 to 0.4 percent of surface active agent, 0.1 to 0.2 percent of pH conditioning agent, 0.3 to 0.6 percent of foam killer, 2.5 to 4 percent of glycol, 1 to 3 percent of alcohol ester-12, 15 to 25 percent of titanium pigment, 4 to 8 percent of mica powder, 10 to 18 percent of coarse whiting, 3 to 6 percent of diatomite, 8 to 13 percent of silicone emulsion, 15 to 25 percent of styrene-acrylate emulsion, 5 to 15 percent of silica sol, 0.1 to 1 percent of mildew preventive, and 0.1 to 0.2 percent of preservative. The nano organosilicone exterior wall paint has the advantages of readily available materials, convenient production and construction, good resistance to soiling of film coating, good hydrophobic nature and alkali resistivity, strong attachment, mildew and aquatic grass resistance, good weather resisting property, and everlasting and fresh color.

Description

technical field [0001] The invention relates to a wall paint for exterior walls, in particular to an environment-friendly exterior wall with strong adhesion, good water resistance, good alkali resistance, mildew and algae resistance, long-lasting bright color, stain resistance and hydrophobicity. paint. Background technique [0002] Problems such as discoloration, powdering, peeling, blooming, mildew, water seepage, and "rain mark" stain resistance of the paint film will affect the quality and appearance of the exterior wall buildings for a long time, and these can be solved by painting the wall paint . At present, none of the exterior wall paints can solve or completely solve these problems, especially the problem of antifouling. Good, water-resistant, alkali-resistant, weak adhesion, some have no elasticity, poor anti-mildew and anti-algae functions, not safe and environmentally friendly. Contents of the invention [0003] In order to overcome the deficiencies of the ...
