Abstract

The invention discloses a vinyl acetate-acrylic emulsion cement external wall latex paint and a preparation method thereof. The vinyl acetate-acrylic emulsion cement external wall latex paint is prepared from the following raw materials in parts by weight: 40-50 parts of vinyl acetate-acrylic emulsion, 8-12 parts of 107 glue, 6-8 parts of white cement, 1-3 parts of bentonite, 8-10 parts of titanium white, 10-14 parts of ground calcium carbonate, 1-3 parts of talcum powder, 1-3 parts of emulsifier, 2-4 parts of SN aid, 1-3 parts of defoaming agent, 12-16 parts of water and 3-5 parts of iron ethylenediamine tetraacetate and ethanediol monomethyl ether in a weight ratio of (2-4):1. The emulsifier is sodium dodecyl benzene sulfonate, the SN aid is SN-640, and the defoaming agent is OTD. The vinyl acetate-acrylic emulsion cement external wall latex paint has the advantages of excellent brush resistance, excellent water resistance, excellent alkali resistance, excellent alternate freezing and thawing resistance and excellent artificial aging resistance.

Description

technical field [0001] The invention belongs to the field of chemical coatings, in particular to an ethylene-propylene emulsion cement exterior wall latex paint and a preparation method thereof. Background technique [0002] Latex paint belongs to water-dispersible paint. As far as its composition is concerned, it consists of four parts like ordinary paint. [0003] (1) Main film-forming substances: such as polyvinyl acetate emulsion, vinegar-acrylic latex, styrene-acrylic latex, all-acrylic latex, silicon-acrylic latex, fluorocarbon emulsion, etc. The main film-forming substance of latex paint, or base material, is the primary factor affecting the performance of latex paint. It is not only related to the hardness, flexibility, water resistance, alkali resistance, scrub resistance, weather resistance and stain resistance of the coating film, but also related to the film-forming temperature of latex paint and the bonding strength to the substrate. Therefore, when designing ...
