Abstract

The invention discloses high-pollution-resistant high weatherproof water-based external wall emulsion paint and a preparation method thereof. The external wall emulsion paint comprises hydrophilic self-crosslinking acrylic emulsion, titanium dioxide, non-transparent polymer, precipitated silica, attapulgite, talcum powder, rutile type nano titanium dioxide, auxiliaries, water and other components. The invention aims at overcoming the defects in the prior art and providing external wall paint with high weather resistance and stain resistance and relatively low production cost; and the invention also aims at providing a method for preparing the external wall paint.

Description

technical field [0001] The invention relates to a high anti-pollution and high weather resistance exterior wall paint, and also relates to a method for preparing the exterior wall paint. Background technique [0002] The traditional concept of exterior wall paint is a kind of self-drying liquid paint for coating the facade of buildings, which can beautify and decorate buildings, and at the same time protect the walls of buildings. In the past 20 years in China, the promotion and application of exterior wall coatings has made great progress. Among all kinds of exterior wall coatings, single-component water-based exterior wall coatings are favored for their simple construction, safety and environmental protection, and competitive cost. , occupying a high proportion of 70% in exterior wall paint topcoat. However, with the long-term use of this type of exterior wall paint, compared with the conventional exterior wall tiles, users are not very satisfied with its weather resistan...
