FIELD: chemistry.
SUBSTANCE: described is a grease lubricant which contains a base oil mixture which is based on oils with viscosity which is common for industrial lubricant materials (from ISO VG 2 to ISO VG 1500), an ionic liquid, a thickener selected from a group consisting of a urea thickener as well as common additives. The grease lubricant can be used at common operating temperatures from higher than 120°C to 260°C, especially at high operating temperatures from higher than 180°C to 260°C, and at low temperatures of up to -60°C. The invention also relates to a method of preparing similar grease lubricant compositions.
EFFECT: longer service life of the grease lubricant, negligible wearing of antifriction bearings, high oil separation.
