High pollution-resistant styreneacrylic latex paint

Abstract

The invention discloses a high pollution-resistant styreneacrylic latex paint, which is mainly prepared by mixing the following raw materials according to the weight proportion: 157 parts of styreneacrylic, 13 parts of dispersing agent, 80 parts of deionized water, 15 parts of oxalic acid adipic dihydrazide, 2 parts of dispersing agent, 4 parts of defoamer, 11 parts of mildew preventive, 23 parts of kaolin, 15 parts of titanium white, 15 parts of heavy calcium powder, 15 parts of texanol and 12 parts of polyethers thickening agent. The invention has the following advantages that: a coating is fine and smooth, and has an elegant mercerizing effect; and the high pollution-resistant styreneacrylic latex paint has good crack resistance, can make up the fine and small cracks of a base layer, has preeminent water resistance, alkali resistance, pollution resistance, weather resistance, and excellent light and color protection performance, can make wall bodies be new for a long time, and has mould resistance, antibiosis and ultraviolet radiation resistance.

Description

technical field [0001] The invention relates to a high pollution-resistant styrene-acrylic latex paint. technical background [0002] Latex paint is a kind of water-based paint prepared by adding pigments, fillers and various additives based on acrylate copolymer emulsion. It is mainly used for interior and exterior wall decoration of buildings. Most latex paints prepared from conventional acrylate copolymer emulsions have good weather resistance and chemical resistance after film formation at room temperature, but poor stain resistance, which seriously affects the use effect of latex paints. The main reason for the poor stain resistance of latex paint is due to the low glass transition temperature (Tg) and high water absorption of the latex paint film: if the Tg is too low, after the latex paint is formed into a film, the paint film will shrink back when the ambient temperature is slightly higher. Sticky, pollutants are easy to adhere to the surface of the paint film to ca...

Most latex paints prepared from conventional acrylate copolymer emulsions have good weather resistance and chemical resistance after film formation at room temperature, but poor stain resistance, which seriously affects the use effect of latex paints

The main reason for the poor stain resistance of latex paint is due to the low glass transition temperature (Tg) and high water absorption of the latex paint film: if the Tg is too low, after the latex paint is formed into a film, the paint film will shrink back when the ambient temperature is slightly higher. Sticky, pollutants are easy to adhere to the surface of the paint film to cause pollution, and it is difficult to remove; in addition, when the water absorption of the latex paint film is too high, the dust (dissolved in water or dispersed) that adheres to the surface of the paint film through the water absorption of the paint film Dust in the water) will be more, which will cause the paint film to be easily dirty
