Problems solved by technology

This kind of flowing medium not only corrodes the pipe wall, but also seriously wears the pipe wall. Once the wear is severe, it will directly cause serious corrosion to the pipe, leading to the scrapping of the pipe, and the workload of re-laying the pipe is often very large.

Abstract

The invention provides a wear-resistant anticorrosive coating, and a preparation method and a brushing method thereof, and relates to the technical field of coatings. The wear-resistant anticorrosivecoating is mainly prepared from the following raw materials in parts by weight: 5 to 25 parts of carbon fiber, 5 to 25 parts of polyphenylene sulfide, 10 to 50 parts of an additive, 30 to 80 parts ofa first component, 50 to 100 parts of a second component and 20 to 50 parts of ceramic microspheres, wherein the additive comprises one or two selected from the group consisting of an inorganic additive and an organic additive; the first component comprises a curing agent and an aging-resistant auxiliary agent with a weight ratio of 1.5: (1-2); and the second component comprises a silane couplingagent, polyethylene glycol and epoxy resin with a weight ratio of 1: 2: (1.5-2.5). According to the invention, the stripe structure of the carbon fiber facilitates dispersing and absorbing the wear force to the coating, so the wear-resistant capacity of the coating is improved; the polyphenylene sulfide can be used as a protective layer of the carbon fiber, so bonding among carbon fibers is more stable; meanwhile, by utilization of the wear resistance of the polyphenylene sulfide, a protective layer to the carbon fiber can be constituted.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a wear-resistant and anti-corrosion coating, a preparation method and a painting method thereof. Background technique [0002] Pipelines are used to transport media, which are widely used in various industries. The transport media include but are not limited to sewage, mud, sea water, and clean water. This kind of flowing medium not only corrodes the pipe wall, but also wears the pipe wall very seriously. Once the wear is severe, it will directly cause serious corrosion to the pipe, resulting in the scrapping of the pipe, and the workload of re-laying the pipe is often very large. Therefore, it is very important for the pipeline layout industry to develop a long-lasting anti-corrosion and wear-resistant coating. Contents of the invention [0003] The object of the present invention is to provide a wear-resistant and anti-corrosion coating, which can carry out long-term corros...
