Abstract

The invention discloses a polymer cement-based waterproof coating. The polymer cement-based waterproof coating comprises an ethylene-vinyl acetate polymer emulsion, a vinyl acetate-acrylate copolymeremulsion, epoxy resin, nanometer silicon dioxide, an organic silicon waterproof agent, Portland cement, ultrafine calcium carbonate powder, talcum powder and filming additives. Through use of the mixed emulsion of the ethylene-vinyl acetate polymer emulsion and the vinyl acetate-acrylate copolymer emulsion, good synergistic promoting effects are obtained, the compactness and mechanical propertiesof the polymer waterproof coating are improved, elasticity is good, elongation is good, anti-permeability, durability and aging resistance are good, a service life is long and waterproof effects are good.

Description

technical field [0001] The invention relates to the field of architectural decoration, in particular to a polymer cement-based waterproof coating. Background technique [0002] Polymer cement-based waterproof coating, also known as JS composite waterproof coating. The polymer cement-based waterproof coating is based on the loss of water from the organic polymer emulsion to form a cohesive and continuous elastic film layer. The cement absorbs the water in the emulsion and hardens. The flexible polymer and the hardened cement body penetrate each other and bond firmly Form a strong and elastic waterproof layer, the flexible polymer is filled in the gap of the hardened cement body, making the hardened cement body more dense and elastic, the coating film has better elongation, and the hardened cement body is filled in the polymer phase , so that it has better outdoor durability and better grass-roots adaptability. Therefore, it has certain rigidity and toughness, and has high a...
