Waterborne antibacterial coating

The invention discloses a waterborne antibacterial coating. The waterborne antibacterial coating is prepared from the following raw materials in parts by weight: 100 parts of acrylate emulsion, 25 to50 parts of cement, 20 to 40 parts of quartz sand, 20 to 30 parts of ground calcium carbonate, 0.2 to 0.8 part of dimethyl silicone oil and 0.2 to 0.8 part of bactericide, wherein the bactericide is aquaternary ammonium salt-fluorosilicone acrylate block copolymer and/or a polyhexylguanidine hydrochloride-polypropylene glycol diglycidyl ether block copolymer. The waterborne antibacterial coatingdisclosed by the invention has the advantages of good tensile strength and elongation at break of a coating, extensive high-efficiency and longer-time sterilization and inhibition abilities for mold and yeast and excellent antibacterial property. 本发明公开了种水性抗菌涂料，包括下述重量份原料：丙烯酸酯乳液100份，水泥25-50份，石英砂20-40份，重质碳酸钙20-30份，二甲基硅油0.2-0.8份，杀菌剂0.2-0.8份。所述抗菌剂为季铵盐-氟硅丙烯酸酯嵌段共聚物和/或聚己基胍盐酸盐-聚丙二醇二缩水甘油醚的嵌段共聚物。本发明的水性抗菌涂料，具有良好的涂膜拉伸强度和断裂伸长率，并且对霉菌、酵母菌有
