Abstract

The invention discloses a preparation method of a coating of grapheme modified polyphenylene sulfide. The preparation method of the coating of grapheme modified polyphenylene sulfide is characterized in that the coating is prepared from, by weight, 45-85 parts of acrylic resin emulsion, 15-40 parts of modified polyphenylene sulfide, 10-40 parts of Teflon, 3-15 parts of filler, 6-18 parts of industrial essence, 2-16 parts of filler, and 1-10 parts of dispersing agent; the filler consists of 2-15 parts by weight of mixed xylenes and 5-30 parts of grapheme; the coating is prepared by step (1) preparation of modified polyphenylene sulfide; step (2) preparation of coating. A stirring tank applied to the invention is provided with a thermodetector which can control temperature of the stirring tank; a time controller is provided for setting the stirring time required; after reaching the appointed stirring time, the stirring tank can be disconnected independently, thereby reducing the mistake of manual operation and improving the accuracy.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a preparation method of a graphene-modified polyphenylene sulfide coating. 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. [0003] In order to reduce the wear and corrosion ...
