Anti-fouling emulsion paint for external walls and preparation method thereof

The invention discloses an anti-fouling emulsion paint for external walls and a preparation method thereof. The anti-fouling emulsion paint comprises, by weight, 4-6 parts of a dispersant, 1-3 parts of hydroxyethyl cellulose, 4-6 parts of a defoaming agent, 4-7 parts of a film forming aid, 180-200 parts of titanium dioxide, 30-50 parts of kaolin, 130-160 parts of heavy calcium carbonate, 130-160 parts of deionized water, 380-460 parts of an acrylate emulsion, 20-40 parts of Sedum lineare powder and 14-18 parts of a synthetic agent. The emulsion paint prepared by using the method is significantly enhanced in anti-fouling ability and surface smoothness, truly achieves lotus leaf effect, realizes waterproof and oil-proof effects, and has greatly improved anti-fouling ability. 本发明公开了种外墙抗污乳胶漆及其制备方法，按重量配比，该乳胶漆由4-6份分散剂、1-3份羟乙基纤维素、4-6份消泡剂、4-7份成膜助剂、180-200份钛白粉、30-50份高岭土、130-160份重质碳酸钙、130-160份去离子水、380-460份丙烯酸酯乳液、佛甲草粉20-40份、14-18份合成剂组成。通过该方法制作的乳胶漆能够显著增强乳胶漆的抗污能力和表面光滑度，真正达到荷叶效应，实现防水防油污效果，抗污能力也得到很大的提高。
