Abstract

The invention discloses a coating material, which consists of the following compositions by weight percentage: 35 to 45 percent of ceramic adhesive, 25 to 35 percent of composite ceramic powder, 8 to 16 percent of composite solid lubricant, 3 to 5 percent of melanizing agent, 0.1 to 0.4 percent of additive, 1 to 3 percent of preservative, 1 to 3 percent of bonding force reinforcing agent and 12 to26 percent of mixed organic solvent. The coating material has the characteristics of normal temperature curing and high temperature using, and also has properties of anti-abrasion, anti-corrosion, and self-lubrication.

Description

technical field [0001] The invention relates to a paint, in particular to a corrosion-resistant, wear-resistant, self-lubricating paint cured at room temperature and used at a high temperature and a preparation method thereof. Background technique [0002] With the continuous development of high technology, the working conditions of construction machinery, equipment and components have become increasingly harsh, such as various tower equipment, pumps, pipelines and water wheel blades in petrochemical industry, gates of hydropower stations, paper mills, etc. Grinding discs, etc., they not only work in a strong corrosion and high temperature environment, but also constantly move and rotate, and bear the impact and wear of different media. General anti-wear and corrosion-resistant coatings do not have sufficient mechanical strength and wear resistance due to the formed coating. After being subjected to long-term impact and mechanical action, they will wear quickly, and even pee...
