The building waterproof paint is a main waterproof material in the current market, and can be divided into various types such as asphalt, polymer modified asphalt, synthetic polymer, inorganic cement, polymer cement and the like according to film forming base materials. The synthetic polymer can be divided into solvent type and water emulsion type products, and the water emulsion type single-component waterproof coating is simple to operate, can be constructed on a wet leveling layer, and is safe in links such as production, storage, transportation, construction and the like, so that the water emulsion type single-component waterproof coating is widely applied to the market.
The acrylic emulsion generally refers to acrylic ester, methacrylic ester, and often emulsion copolymerized with a small amount of acrylic acid, methacrylic acid and the like, and the emulsion is characterized by excellent weather resistance, color retention and gloss retention. The acrylic ester emulsion mainly comprises pure acrylic emulsion, styrene-acrylic emulsion, acrylic ester cross-linked emulsion and the like at present, wherein the pure acrylic emulsion is usually prepared by copolymerizing methyl methacrylate serving as a hard monomer component, butyl acrylate and ethyl acrylate serving as soft components and adding a small amount of acrylic acid or methacrylic acid. The styrene-acrylic emulsion is prepared by using styrene or partially or completely replacing methyl methacrylate in the pure acrylic emulsion, so that the alkali resistance, the hardness and the stain resistance of the coating film are improved, but the light stability, the weather resistance and the aging resistance of the coating film are reduced. The Chinese invention patent CN104263107A discloses a styrene-acrylic emulsion waterproof coating, which is prepared by mixing styrene-acrylic emulsion as a main component with some pigments, fillers, film-forming additives and the like, and the waterproof performance of the prepared waterproof coating can only reach water impermeability of 1 hour under 0.3 MPa. With the continuous development and refinement of the domestic coating industry, the market has higher and higher requirements on the waterproof and anti-permeation capability of the waterproof coating. Therefore, the waterproof performance of the waterproof coating prepared by using the styrene-acrylic emulsion as the main component of the single emulsion needs to be further improved.
