Lubricating grease composition

摘要

A lubricating grease composition for extra heavy duty extreme pressure applications comprises a major amount of a synthetic base oil a lithium complex thickener, at least one extreme pressure agent; and at least 5 wt. % of molybdenum disulfide, based on a total weight of the lubricating grease composition.

1. A lubricating grease composition comprising:
a) a major amount of a synthetic base oil having a kinematic viscosity at 40° C. from 150 mm2/s to 250 mm2/s; b) a lithium complex thickener; c) 2.5 wt. % or 3 wt. % of at least one extreme pressure agent, based on a total weight of the lubricating grease composition; and d) 5 to 20 wt. % of molybdenum disulfide, based on the total weight of the lubricating grease composition; wherein the at least one extreme pressure agent is selected from the group consisting of sulfurized animal or vegetable fats or oils; sulfurized animal or vegetable fatty acid esters; sulfurized olefins; dihydrocarbyl polysulfides; sulfurized Diels-Alder adducts; sulfurized dicyclopentadiene; sulfurized or co-sulfurized mixtures of fatty acid esters and mono-unsaturated olefins; co-sulfurized blends of fatty acids, fatty acid esters and alpha-olefins; functionally-substituted dihydrocarbyl polysulfides; thio-aldehydes; thio-ketones; epithio compounds; sulfur-containing acetal derivatives; co-sulfurized blends of terpene and acyclic olefins and polysulfide olefin products; and mixtures thereof.
