Abstract

The invention relates to high temperature wear-resistant paint. The technical scheme adopted by the invention is as follows: the high-temperature wear-resistant paint is characterized by comprising the following components: corundum fine powder, cement, fluorinated graphite, titanium dioxide, barium sulfate, talcum powder, aluminum triphosphate, sodium persulfate, N,N-dimethyl ethanolamine, aluminum oxide, calcium oxide, ammonium ferrous sulfate, silica micro powder and phosphoric acid. The high-temperature wear-resistant paint has the beneficial effects that the mechanical performances are excellent, the impact resistance is good, the high temperature resistance is excellent, the adhesive force is good, the scratch resistance and the wear resistance are excellent, the cost is low and the performances are stable.

Description

technical field [0001] The invention relates to a high-temperature wear-resistant coating, which belongs to the technical field of coatings. Background technique [0002] Coatings used in circulating fluidized bed boilers and other equipment in thermal power plants not only need high temperature resistance, but also need to have wear resistance, mechanical properties, not easy to crack, fall off and long service life. Conventional coatings generally cannot have multiple properties at the same time, so the disadvantages of short service life and high cost are caused. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-temperature wear-resistant coating, which has the characteristics of high mechanical strength, stable performance, good impact resistance, high temperature resistance, good adhesion, good scratch resistance and wear resistance, and low cost. [0004] In order to solve the problems of the technolo...
