MULTI-PURPOSE LOW-TEMPERATURE PLASTIC LUBRICANT Russian patent published in 2018 - IPC C10M101/02 C10M169/02 C10M119/24 C10M133/12 C10N30/02 C10N30/06 

FIELD: technological processes.

SUBSTANCE: invention relates to the production of a multi-purpose low-temperature lubricant for friction units operating in the temperature range from minus 60 to plus 150 °C, and can be used in the oil refining and petrochemical industries. Essence: a multi-purpose low-temperature lubricant contains (wt. %): polyurea thickener based on polyisocyanate containing isocyanate groups from 29.0 to 31.0 % 8.0–18.0; amine type antioxidant 0.2–0.5; phenolic type antioxidant 0.2–0.5 and oil for the production of chemical fibers with kinematic viscosity at a temperature of 50 °C not more than 9 mm²/from – rest is up to 100.

EFFECT: increased rheological characteristics, including at low temperatures and increased oxidative stability for friction units of mobile equipment, machinery and equipment.
