Antifriction paste and solid antifriction coating prepared from same

摘要

An antifriction paste containing epoxy resin, molybdenum disulphide, graphite, aluminum, copper, alumosilicate and polyethylenepolyamine, the components being used in the following proportions (in parts by weight): epoxy resin: 40-80 molybdenum disulphide: 15-30 graphite: 10-15 aluminum: 5-10 copper: 5-10 alumosilicate: 8-15 polyethylenepolyamine: 5-10. The antifriction paste may also contain a solvent for the epoxy resin in an amount from 5 to 30 parts by weight. This paste is suitable for both small-and large-size friction assemblies. On the basis of this paste a solid lubricating coating with high antifriction performance is produced. Thus, a coefficient of sliding friction ffr. at a sliding speed V=0.06 m/s at a load P=10 kgf/cm2 is 0.2; linear wear rate Ih under the same conditions is 1.0.10-9, and service life is as high as 500 km.
