The invention relates to a mildew-proof polymer cement waterproof coating and a preparation method thereof. The waterproof coating comprises a liquid material and a powder material, wherein the liquidmaterial is prepared from the following components in parts by weight: 95 to 105 parts of a quaternary ammonium salt modified acrylate emulsion, 4 to 6 parts of a liquid material additive and 0 to 40parts of water; the quaternary ammonium salt modified acrylate emulsion is prepared from polymerization monomers of n-butyl acrylate, styrene and acrylamide and functional monomers of methacryloyloxyethyl trimethyl ammonium chloride through emulsion polymerization; the powder material is prepared from the following components in parts by weight: 65 to 75 parts of cement, 30 to 40 parts of groundcalcium carbonate, 30 to 40 parts of quartz powder, 2.2 to 2.6 parts of silica fume, 0.8 to 1.4 parts of sodium silicate and 0 to 4 parts of a powder material auxiliary agent. The waterproof coating has good dry film antibacterial and mildew-proof properties, is matched with excellent waterproofness and low water absorption of a coating layer, is not prone to breeding bacteria and mildew even after being soaked in water for a long time in a humid environment, and has long-acting antibacterial and mildew-proof properties.
本发明涉及一种防霉型聚合物水泥防水涂料及其制备方法，该防水涂料包括液料和粉料；所述液料包括以下重量份的组分：季铵盐改性丙烯酸酯乳液95‑105份、液料助剂4‑6份、水0‑40份；所述季铵盐改性丙烯酸酯乳液是由聚合单体丙烯酸正丁酯、苯乙烯、丙烯酰胺和功能单体甲基丙烯酰氧乙基三甲基氯化铵通过乳液聚合制成的；所述粉料包括以下重量份的组分：水泥65‑75份、重质碳酸钙30‑40份、石英粉30‑40份、硅灰2.2‑2.6份、硅酸钠0.8‑1.4份、粉料助剂0‑4份。该防水涂料具有良好的干膜抗菌防霉性，配合涂层本身优异的防水性和低吸水率，在潮湿环境甚至长期浸水后，也不易滋生细菌霉菌，抗菌防霉具有长效性。
