PLASTIC ANTIFRICTION HIGH-TEMPERATURE WATER-RESISTANT LUBRICANT Russian patent published in 2017 - IPC C10M169/04 C10M125/00 C10N30/08 

FIELD: chemistry.

SUBSTANCE: lubricant includes as starting components a mineral oil base, a calcium sulfonate thickening agent, 12-hydroxy stearic acid and additives, further comprising acetic acid, diphenylamine or Naftam-2, or Agidol-1 (4-methyl-2,6-di-tert-butylphenol) as an antioxidant additive, zinc dialkyl dithiophosphate or an additive containing sulfur, phosphorus and nitrogen as an anti-wear and anticorrosive additive, while a mineral oil is a mixture of highly refined mineral base oils: residual oil and a low-hardening oil component, taken in the ratio of 4:1, with the following component ratio, wt %: calcium sulfonate 30-43, 12-hydroxystearic acid 2.0-5.0, acetic acid 8.0-14, 0, Agidol-1, or Naftam-2, or Diphenylamine 0.1-1.0, zinc dialkyldithiophosphate, or an additive-containing sulfur, phosphorus and nitrogen, 0.5-2.5, a mixture of highly refined mineral base oils - the rest.

EFFECT: high low-temperature and lubricating properties, working at low ambient temperatures and maintaining its performance at high temperatures in heavy-loaded friction units, protecting lubricated parts against corrosion at high humidity.
