LIQUID OLIGOMETHYLOROXYL SILOXANES AND OLIGOETHYLOXYLICYLOXANES BASED LUBRICATING OIL Russian patent published in 2018 - IPC C10M107/50 C10M161/00 C10M169/00 C10N30/00 C10N20/02 

FIELD: instrument engineering.

SUBSTANCE: present invention relates to the silicone-based liquid lubricating compositions, in particular, to the mixed lubricating oils based on oligomethyl octyl or oligoethyl octyl siloxane base in combination with petroleum oil and/or complex organic ether, which find application in various industries to ensure the friction units operation in the extended temperature range and as the greases basis. Lubricating oil for the products and mechanisms stable operation, in which steel-steel friction pairs are present, based on oligoorganosiloxanes, where as the oligoorganosiloxane the oligomethyl octyl and oligoethyl octyl siloxane liquids are contained with viscosity of 100÷300 mm²/s at 20 °C, petroleum oil with viscosity of 6÷110 mm²/s at 40 °C and/or dicarboxylic ester (bis-(2-ethylhexyl)sebacic acid ester – DOS) with the following content of components, wt. %: oligomethyl octyl or oligoethyl octyl siloxane 40–80, mineral oil and/or DOS 20–60.

EFFECT: inventions find application in various industries to ensure the friction units operation in the extended temperature range and as the basis of greases.
