LUBRICATING COMPOSITION Russian patent published in 2022 - IPC C10M117/00 C10M119/00 C10M101/00 

FIELD: chemistry.

SUBSTANCE: invention relates to a complex calcium lubricating composition. A lubricating composition is described, containing base oil selected from paraffin mineral oils, naphthene mineral oils, base GTL oils, and mixtures thereof, and a thickener consisting of complex calcium soap, wherein the specified thickener, as carboxylic acids composing complex calcium soap, contains substituted or unsubstituted C18-22 higher mono-fatty acid with a straight chain; substituted or unsubstituted aromatic monocarboxylic acid having a benzene ring; from 5 to 30 weight parts of saturated C2-4 lower mono-fatty acid with a straight chain per 100 weight parts of the total amount of carboxylic acid; and from 1 to 70 weight parts of substituted or unsubstituted saturated dicarboxylic acid containing from 4 to 20 carbon atoms per 100 weight parts of the total amount of carboxylic acid, wherein the amount of a compound of calcium dicarboxylate is from 5 to 70 wt.% per the total weight of the thickener; at the same time, mixed amount of base oil is from 60 to 99 weight parts per 100 weight parts of the total amount of the lubricating composition, and mixed amount of complex calcium soap is from 1 to 40 weight parts per 100 weight parts of the total amount of the lubricating composition.

EFFECT: creation of a lubricant with increased shear resistance.
