Abstract

The invention discloses a high load-bearing wear-resistant nanometer coating, which consists of an adhesive, a solid lubricant, an auxiliary agent, a nanometer filler, and a mixed organic solvent. The adhesive is one-component moisture-curable polyurethane, the solid lubricant is polyfluo wax, the auxiliary agent is a melamine-cyanuric acid complex, the functional filler is titanium dioxide nanotubes, and the mixed solvent consists of acetone and ethyl acetate. The coating has good abrasion resistance, friction-reduction performance and high load-bearing performance, and also has good oil medium resistance and hydrophobic property, convenient construction and small pollution to the environment; and a sliding component sprayed with the coating can be used for a long time in the environment of dry friction and oil medium.

Description

technical field [0001] The invention describes a high-load-bearing anti-wear nano coating. The invention is an anti-friction, anti-friction and anti-fouling nano-coating suitable for dry friction and oil medium on the surface of mechanical parts under the working condition of film thickness of 20 μm to 100 μm. Background technique [0002] With the advancement of modern plastic processing technology and the rapid development of aviation, aerospace, and automobile industries, the demand for plastic processing of complex shape parts and difficult-to-deform materials is increasing. Surface engineering technology is used to make one or more layers of composite materials on the surface of materials. Anti-friction and anti-wear coatings are a very effective way to make up for the lack of materials and the failure of liquid lubrication. Chinese patent 03140835.4 has the advantages of long life, low friction, load resistance and other advantages of solidification at room temperatur...
