Abstract

The invention discloses a scrubbing resistance two-component acetic acrylic polymer modified cement-base waterproof coating and a preparation method thereof. The scrubbing resistance two-component acetic acrylic polymer modified cement-base waterproof coating is prepared from a liquid material A and a powdery material B on the basis of the mass ratio being (1-2):1, wherein the liquid material A is prepared from vinyl acetate-acrylic emulsion, nanometer aluminum oxide sol, texanol ester alcohol, vinyl trimethoxy silane, polyethyleneimine and the like; the powdery material B is prepared from Portland fly-ash cement, calcium silicate slag, asbestos tailings, activated aluminum oxide, oil shale residues and the like. According to the waterproof coating, a mixture of the vinyl acetate-acrylic emulsion with the solid content being 50% and the nanometer aluminum oxide with the solid content being 25% is adopted as a film forming material, the vinyl trimethoxy silane, glycidyl methacrylate and other components are added to be modified, the scrubbing resistance function of the waterproof coating can be improved remarkably, meanwhile, hemp-fibred plaster, silicon whiskers and other components are added, the mechanical property of the waterproof coating can be improved, and the abrasion resistance, anti-aging cracking performance and heat resistance of the waterproof coating can be improved.

Description

technical field [0001] The invention relates to a scrub-resistant two-component vinegar-propylene polymer cement-based waterproof coating and a preparation method thereof, belonging to the field of waterproof coatings. Background technique [0002] Two-component polymer cement-based waterproof coating is a two-component waterproof coating based on water-based polymer dispersion and cement. The two components are stirred on site to form a uniform and fine slurry, which is brushed or sprayed on the surface of the substrate. After curing Form a flexible, high-strength waterproof coating film. This kind of coating not only has the advantages of high strength of cement-based cementitious materials, is easy to bond with wet substrates, but also has the advantages of high elasticity and good water resistance of the polymer coating film. The disadvantage of waterproof coatings polluting the environment is a new type of green and environmentally friendly waterproof coating that is n...
