Abstract

The invention discloses an environment-friendly closed building exterior wall paint and a preparation method thereof. The exterior wall paint consists of components in terms of mass percentage: 25-30% of water, and 28-35% of ZS-6501 back cover emulsion , A-90 anti-alkali back cover emulsion is 28-35%, high-efficiency coalescent JS-PPH (302) is 1-4%, ultra-fine mica powder is 4-9%, anti-mold preservative SPM is 0.2-1 %, GHP-102 thickener is 0.2-1.2%, silicone defoamer JS-2010S is 0.2-1%. The exterior wall paint of the present invention is green and environment-friendly, has strong penetrating power, has the advantages of super-long water resistance, strong alkali resistance, excellent adhesion, good sealing effect, etc., and can maintain the beautiful appearance of buildings for a long time.

Description

technical field [0001] The invention belongs to the technical field of coatings and relates to an architectural coating, more specifically to an environment-friendly closed building exterior wall paint and a preparation method thereof, which are mainly used in the field of building exterior wall coatings. Background technique [0002] With the gradual improvement of environmental protection requirements, the restrictions on VOC content in various countries are becoming increasingly strict, and the use of existing solvent-based exterior wall paints is increasingly subject to certain restrictions. At present, the exterior wall paint of closed buildings is beginning to develop in the direction of environmental friendliness and low VOC content. Ordinary closed exterior wall emulsion, due to its poor water resistance and alkali resistance, cannot effectively prevent the precipitation of salt and alkali on the wall, which will cause defects such as blooming, whitening, and discolo...
