LOW-TEMPERATURE LUBRICATING OIL BASED ON POLYETHYLSILOXANE Russian patent published in 2022 - IPC C10M107/50 C10M101/00 C10N30/00 

FIELD: lubricating materials.

SUBSTANCE: invention relates to liquid lubricants based on organosilicon, in particular to low-temperature mixed lubricating oils based on polyethylsiloxane, which are used in various branches of transport, industry, industrial equipment and marine mechanisms for various purposes, transmissions and high-loaded helicopter units to ensure the operation of friction units in extreme conditions. Low-temperature oil consisting of the following components: polyethylsiloxane liquid PES-3 with a viscosity of 14-17 mm²/s, mineral oil TSgip (transmission oil for hypoid gears) TU 38.1011332-90, additives of liquid ashless dithiophosphate Irgalube 353 and Agidol-1 TU 38.5901237, with the following component content, wt. %: polyethylsiloxanes 30-70; TSgip TU 38.1011332-90 up to 100; Irgalube 353 0,25-2,0; Agidol-1 TU 38.5901237 0,1-0,3 .

EFFECT: improving the low-temperature and starting properties of the lubricant while maintaining the antifriction and protective properties at the required level.
