HIGH-TEMPERATURE MULTI-PURPOSE UNIVERSAL LUBRICANT Russian patent published in 2017 - IPC C10M169/04 C10M117/02 C10M101/02 C10N30/06 

FIELD: chemistry.

SUBSTANCE: invention relates to a multi-purpose universal high-temperature lubricant intended for use in friction units of loaded industrial equipment, modern vehicles, industrial, construction and marine equipment operating at a temperature of -35°C to +160°C, under conditions of high humidity and acidity. Multi-purpose universal high-temperature lubricant includes mineral oil, thickener and antioxidant, anti-scuffing, adhesion and anticorrosive additives. It additionally contains High-tech 343, Anglamol-99 or Anglamol 33 as an antifriction additive including phosphorus, sulfur and nitrogen, 1,2,3 benzotriazole as a corrosion inhibitor, and a dye-pigment, blue phthalocyanine. Isobutylene polymer is used as a thickener, zinc dialkyl dithiophosphate is used as an anticorrosive and antiwear additive, Akor-1 in the form of a nitrated oil of M-8 type with 10-11% of technical stearin is used as an anticorrosive additive, Agidol-1(4-methyl-2,6-di-tert-butylphenol), Naftam-2 or Diphenylamine is used as an antioxidant additive of phenolic type, and the following is used as a mineral oil: a mixture of three highly purified mineral base oils consisting of a residual oil component, a distillate III vacuum residue oil component and a low-hardening oil component, taken in the ratio of 3:1:2, with the following ratio of components, wt %: complex lithium soap of 12-hydroxystearic acid 18-26; 1,2,3 benzotriazole 0.3-0.8; Akor-1 0.4-0.8; isobutylene polymer 1.0-2.0; zinc dialkyl dithiophosphate 0.3-0.7; High-tech 343, Anglamol-99 or Anglamol-33 1.5-2.5; Agidol-1(4-methyl-2,6-di-t-butylphenol), Naftam-2 or Diphenylamine 0.3-1.0; blue phthalocyanine pigment 0.7-1.2; mixture of mineral base oils - the rest.

EFFECT: creation of a universal multi-purpose high-temperature antifriction lubricant, capable of operating in a wide temperature range with a high upper limit of use, which has a low cost.
