FIELD: chemistry.
SUBSTANCE: invention relates to grease based on mineral oils or mixtures thereof, containing fine filler materials, wherein the grease is modified with iron nanoparticles, formed after mixing in a reactor with mixer rate of 1000-2500 rpm with liquid iron pentacarbonyl and further thermal decomposition thereof at temperature of 250-300°C with a working mixture for 30-120 minutes, and a ternary mixture powdered filler materials - graphite (A), molybdenum disulphide (B) and tetrafluoroethylene (C) - is then added to the obtained mass in the same reactor in ratio A:B:C ranging from 40:40:20 to 80:10:10, wherein the grease contains the following, pts.wt: mineral oil or mixture of mineral oils 100, iron nanoparticles 0.3-4.0 and ternary mixture of powdered filler materials 15-60.
EFFECT: obtaining grease with improved temperature, anti-friction and strength properties.
