Abstract

The invention discloses a polymer cement waterproof coating, belonging to the technical field of building coatings. The polymer cement waterproof coating consists of liquid and powder, wherein the liquid contains an emulsion, a stabilizer, a plasticizer, a film forming agent, a dispersing agent, a preservative and water; the powder contains cement and filler; the stabilizer contains inorganic salt, chitosan degradation liquid, gellan gum liquid and terephthalaldehydel; and the filler is prepared from nano-expanded graphite, nano-calcium carbonate and quartz sand through compounding. The polymer cement waterproof coating prepared by virtue of the technical scheme of the invention has excellent water resistance and storage stability, and meanwhile, the mechanical properties of the polymer cement waterproof coating are remarkably improved.

Description

technical field [0001] The invention discloses a polymer cement waterproof coating, which belongs to the technical field of architectural coatings. Background technique [0002] Polymer cement waterproof coating, referred to as JS waterproof coating, J refers to polymer, S refers to cement, so JS is polymer cement waterproof coating. Polymer cement waterproof coating is an organic liquid composed of polyacrylate emulsion, ethylene-vinyl acetate copolymer emulsion and other polymer emulsions and various additives, and inorganic powder composed of cement, quartz sand, various additives, and inorganic fillers. It is a kind of two-component, water-based building waterproof coating made by reasonable proportioning and compounding. Its waterproof mechanism is to block the penetration of water or the penetration of water molecules by forming a complete coating film. Many polymeric materials form complete and continuous films after drying. There are some gaps between the molecule...
