FIELD: greasing materials.

SUBSTANCE: invention relates to greases for heavily loaded friction units and can be used both in the production of greases at oil refining enterprises and in the conditions of enterprises operating agricultural machinery. Grease for heavily loaded friction units contains purified clarified waste mineral motor oil in an amount of 70-75 wt%, still residues of synthetic fatty acids production in an amount of 20-25 wt%, calcium hydroxide in an amount of 2-3 wt%, an antiwear additive comprising purified clarified waste mineral motor oil in an amount of 1 wt% with a powdered filler placed in it taken in an amount of 0.2-0.3 wt% and consisting of an ultrafine powder of molybdenum disulfide, a powder of an alloy of brass and phosphorus in a ratio of 50:30:15, the filler also contains medium-layer graphenes in the amount of 0.1 wt.% and ammonium hydroxide in the amount of 10-12 wt.%. EFFECT: proposed composition of the lubricant will provide high antiwear properties and restore worn friction surfaces under the action of the additive.
