Abstract

The invention belongs to the technical field of filter felts, and particularly relates to an antioxidant PPS filter material and a preparation process thereof. The preparation process comprises the following steps: S1, an electret A and an electret B are prepared, wherein the electret A is prepared from polyethylene, polyurethane, PTFE, organic silicon and deionized water, and the electret B is composed of carbon nanofibers, titanium dioxide nanofibers, PTFE, epoxy resin and deionized water; S2, carding is conducted, and the prepared electret A is used to spray the surfaces of a first surfacelayer, a second surface layer and a third surface layer respectively; and S3, lapping is conducted, the number of lapping layers of the first surface layer is 6-8, the number of layers of the second surface layer is 10-15, and the number of layers of the third surface layer is 5-10. According to the antioxidant PPS filter material and the preparation process thereof, by arranging the electret A and the electret B, the PPS limit oxygen index can be effectively increased, and the electret material is widely applied to the field of high-efficiency low-resistance air filter materials. The electretair filtering material requires high density, long service life and high stability of charges stored in the material.

Description

technical field [0001] The invention relates to the technical field of filter felts, in particular to an antioxidant PPS filter material and a preparation process thereof. Background technique [0002] The main goal of industrial dust removal technology is to control the emission of flue gas particulate matter from pollution sources and reduce air pollution. At present, for the treatment of industrial high-temperature flue gas, three methods are mainly adopted: wet dust removal, electrostatic dust removal, and bag dust removal. Among them, bag dust collectors are all in terms of dust removal efficiency, one-time and long-term investment costs, equipment requirements and performance. Better than wet dust removal and electrostatic dust removal, it will gradually replace the latter two and occupy the mainstream industrial dust collector market. The core of the bag filter is the high temperature resistant filter material, and the performance of the high temperature resistant fi...
