Abstract

The invention discloses a high-strength industrial filter cloth and a preparation method thereof. The high-strength industrial filter cloth comprises, by weight, 30 to 40 parts of polyphenylene sulfide yarn, 5 to 10 parts of HDPE, 10 to 20 parts of nylon resin, 4 to 6 parts of polydimethylsiloxane, 0.3 to 0.6 part of carbon black and 6 to 10 parts of BuGong tea saponin. The invention has the following beneficial effects: the polyphenylene sulfide yarn and the nylon resin are used as base materials for preparation of the filter cloth, so the filter cloth has the advantages of high mechanical strength, high temperature resistance, resistance to chemicals, flame retardancy, good thermal stability, excellent electrical performance, etc.; meanwhile, the BuGong tea saponin is used as an additive, so the industrial filter cloth has greatly improved water-absorbing quality, luster and hand feeling.

Description

technical field [0001] The invention relates to an industrial filter cloth, in particular to an industrial filter cloth and a preparation method thereof. Background technique [0002] Industrial filter cloth is a filter medium woven from natural fibers and synthetic fibers. It is mainly used for solid-liquid separation, gas-solid separation and industrial dust removal; the existing synthetic fibers for industrial filter cloth mainly include polypropylene, polyester, nylon, vinylon, etc. Among them, polyester and polypropylene are the most commonly used, mainly for solid-liquid separation. In a broad sense, industrial filter cloth also includes various metal material woven meshes such as stainless steel wire, nickel wire, and brass wire. The weaving method adopts plain weave, twill weave and satin weave, and non-woven needle punching. It is characterized by high precision, strong load, acid resistance, alkali resistance, temperature resistance, wear resistance, and special f...
