Modified polyphenylene sulfide coating and application thereof

Abstract

The invention discloses a modified polyphenylene sulfide coating and the application thereof. The modified polyphenylene sulfide coating consists of the following components by weight percentage: 60-90 percent of polyphenylene sulfide resin, 3-25 percent of poly-perfluorinated ethylene propylene resin, 3-20 percent of ethylene-tetrafluoroethylene copolymer resin, 1-5 percent of molybdenum disulfide, 1-5 percent of graphite and the balance of filler, wherein the filler is any one of or a mixture of zinc oxide, aluminum oxide, silicon carbide and chromium sesquioxide. The modified polyphenylene sulfide coating disclosed by the invention has the advantages that the compatibility among the components is good; a prepared coating layer has higher corrosion resistance, higher self-lubricity and strong wear-resistant ability, is resistant to high temperature, is highly insulated, has good toughness, can bear impact force capable of being borne by a metal surface, has excellent bond performance with a metal material and is particularly suitable for the using and working condition of cold / hot sudden changes which cannot be borne by glass lining equipment; and through spraying the coating disclosed by the invention on the surface of the metal matrix material, a manufactured work piece has excellent physical-chemical performance, a long service life and a wide application range.

Description

technical field [0001] The invention relates to polyphenylene sulfide modified coatings and applications thereof, in particular to anti-wear and corrosion-resistant polyphenylene sulfide modified coatings and applications thereof. Background technique [0002] In industrial production equipment, the dynamic friction mechanism of the equipment, the crude oil pipeline that transports gravel, the chemical pipeline that transports granular materials, and the flue gas pipeline that discharges dust, etc., are used in corrosive environments, especially in severe cold and high temperature for a long time Crude oil pipelines containing gravel and flue gas discharge pipelines containing dust in the environment will be subject to double hazards of abrasion and corrosion during use, resulting in short service life of the components and high frequency of replacement, increasing operating costs and causing The continuity and safety of industrial production bring great difficulties.
