Abstract

The present invention is a kind of polymer latex coating, and the raw materials used are: 20-21 g of itaconic acid, 350-360 g of ethyl acrylate, 71-73 g of allyl polyoxyalkylene epoxy ether, 71-73 g of ethyl -2-methyl 1,3-dioxopentyl-4-yl acrylate 10-10.5g, methyl methacrylate 42-44g, fatty alcohol polyoxyethylene ether XL-90 2-2.3g, ammonium persulfate 1.9- 2.1g, deionized water 550-600g, mixed into a polymer emulsion. Take 80g of polymerization emulsion, add 17g of water and 3g of thickener, stir to thicken evenly, filter out the material to obtain the product. The coating film material can improve the filtration efficiency of the filter material while maintaining the original technical performance by coating the surface of the air outlet side.

Description

technical field [0001] The invention relates to a multi-performance coating filter material and a preparation method, and specifically discloses a processing method of a fiber layer filter material and a polymer latex coating. Background technique [0002] Composite fiber filter cotton DE type air filter material main body and PP ultra-fine fiber melt-blown cotton, high-density membrane superimposed to form a composite material bag-type and plate-type filter, PP ultra-fine fiber melt-blown cotton is improved by the method of standing. The filtering effect of the filter medium has high requirements on the use environment and short service period. [0003] In view of the shortcomings of composite materials, it is generally used to increase the density and thickness of the fiber layer filter material to improve the filtration level. The gram weight per square meter increases, the cost increases, and it is difficult to exceed the F7 level. To solve the above problems, we have de...
