Abstract
The invention discloses a high-water-resistance two-component siloxane-acrylate copolymer cement-based waterproof coating and a preparation method thereof. The coating is prepared from a liquid material A and a powdery material B in a mass ratio of 1: (1.5-2). The liquid material A is prepared from raw materials consisting of silicone acrylic emulsion, polyethylene glycol, trifluoroethyl methacrylate, octyldodecyl beeswax, polyribosome acrylate, disodium methylene dinaphthalene sulfonate, liquid paraffin, albolene, hydroxyethyl cellulose, Span-20, water and the like. The powdery material B is prepared from raw materials consisting of magnesium-slag Portland cement, river sand, silicon phosphorate, dickite, magnesium hexafluorosilicate hexahydrate, vanadium extraction tailings, halloysite slag, hydrophobic fumed silica, dolomite, converter slag, clastic rock, calcium rosinate, etc. The two-component siloxane-acrylate copolymer cement-based waterproof coating prepared in the invention is low in water absorption capacity and good in water resistance, does not swell in case of soaking in water and has excellent caking properties, corrosion resistance, temperature tolerance and ageing resistance.
Description
technical field [0001] The invention relates to a high water resistance two-component silicone-acrylic 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...
