Abstract

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.

Description

technical field [0001] The invention relates to a multi-performance coated filter material and a preparation method thereof, specifically disclosing a processing method of a fibrous layer filter material and a polymer latex coating, and the filter material satisfies the application of the product in environments such as automobiles, chemicals, medicines, and fresh air. Background technique [0002] Composite fiber filter cotton DE type air filter material main body and PP superfine fiber melt-blown cotton, high-density film composite material production bag, plate filter, PP superfine fiber melt-blown cotton is improved by standing level The filtering effect of the filter medium has high requirements on the use environment and a short service life. [0003] In view of the shortage of composite materials, the density and thickness of the fiber layer filter material are generally increased to improve the filtration level, the weight per square meter increases, the cost increas...
