Abstract

The invention discloses a high dirt resistance exterior wall latex paint capable of degrading haze and a production process thereof. The high dirt resistance exterior wall latex paint capable of degrading the haze comprises raw materials with percentage by weight: water 15.0-25.0%, alkali swelling thickening agents 0.5-1.0%, potential of hydrogen (pH) adjusting agents 0.1-0.2%, antifoaming agents 0.2-0.5%, wetting agents 0.1-0.3%, dispersing agents 0.3-0.6%, ethylene glycol 1.5-2.5%, coalescing agents 1.8-2.5%, titanium dioxide 0-20.0%, ground calcium carbonate 20.0-30.0%, titanium dioxide 0.2-0.6%, silicone modified acrylate emulsion 30.0-40.0%, bactericide 0.2-0.4% and polyurethane thickening agents 0.2-0.5%. The production process of the high dirt resistance exterior wall latex paint capable of degrading the haze comprises two stages of pulping and paint mixing. The high dirt resistance exterior wall latex paint capable of degrading the haze accords with national standard GB/T9755-2014 performance features of exterior wall latexes, and further has the functions of haze degrading and high dirt resistance.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a highly sticky and stain-resistant exterior wall latex paint capable of degrading smog and a production process thereof. Background technique [0002] The exterior wall latex paint, which uses water as the medium, is more in line with the requirements of green environmental protection than the solvent-based exterior wall paint. The latter contains more than 40% volatile solvents, a large number of which are cheap xylene and No. 200 solvents. Gasoline and these toxic solvents all volatilize into the atmosphere along with the film formation of the paint, wasting resources and polluting the environment. Most of the plasticizer components in its formula are substances similar to estrogen, which is extremely harmful to men. The main function of the exterior wall latex paint is to decorate and protect the building surface, so that the appearance of the building is neat and ...
