Multi-performance coating filtering material and preparation method thereof

The invention relates to a polymerized emulsion coating which is prepared by mixing the following raw materials by weight: 20 to 21 g of itaconic acid, 350 to 360 g of ethyl acrylate, 71 to 73 g of allyl polyoxy alkyl epoxy ether, 10 to 10.5 g of ethyl-2-methyl 1, 3-dioxopentyl-4-yl acrylate, 42 to 44 g of methyl methacrylate, 2 to 2.3 g of fatty alcohol-polyoxyethylene ether XL-90, 1.9 to 2.1 g of ammonium persulfate and 550 to 600 g of deionized water, and the raw materials are mixed into a polymerized emulsion. 80g of the polymerized emulsion is taken, 17g of water and 3g of a thickening agent are added, stirred and thickened uniformly, and filtered and discharged to obtain the product. According to the coating film material, the surface of the air outlet side is covered with a film, so that the filtering efficiency of the filtering material is improved while the original technical performance is kept. 本发明是一种聚合乳胶涂层，采用的原料按重量配比为：衣康酸20-21g、丙烯酸乙酯350-360g、烯丙基聚氧烷基环氧基醚71-73g、乙基-2甲基1，3二氧戊基-4基丙烯酸酯10-10.5g、甲基丙烯酸甲酯42
