Abstract

The invention provides a corrosion-resistant and wear-resistant silicon carbide composite material protective agent and a preparation method thereof, and belongs to the technical field of wear-resistant protective agents. The corrosion-resistant and wear-resistant silicon carbide composite material protective agent is prepared from the following raw materials in parts by weight: 20 to 35 parts of vinyl resin, 1 to 10 parts of curing agent, 160 to 280 parts of silicon carbide, 20 to 50 parts of aluminum oxide, 15 to 20 parts of sepiolite mineral fiber, 1 to 8 parts of emulsifier, 20 to 35 parts of filler and 3 to 7 parts of tackifier. The protective agent contains vinyl resin, aluminum oxide, silicon carbide, sepiolite mineral fibers and the like, and when the protective agent is applied to a surface needing to be protected, the effect of prolonging the service life of equipment can be achieved, and the problem that in the industrial production process, the service life of related equipment is greatly shortened due to the influence of strong acid, strong alkali and temperature and the extreme operating environment is solved.

Description

technical field [0001] The invention belongs to the technical field of anti-wear protective agents, and in particular relates to an anti-corrosion and wear-resistant silicon carbide composite material protective agent and a preparation method thereof. Background technique [0002] Anti-wear protective agent, widely used in the repair of various wear parts and the preparation of wear-resistant and anti-corrosion coatings on the surface of various parts that require wear resistance and corrosion resistance, such as pump bodies, impellers, Repair and pre-protection of fan casings, pipe elbows, pipe augers, etc. [0003] In the domestic industrial production process, strong acid and strong alkali are common, coupled with the influence of temperature, and the extreme operating environment has greatly shortened the life of related equipment. Contents of the invention [0004] The purpose of the present invention is to provide an anti-corrosion and wear-resistant silicon carbide...
