FIELD: machine building.
SUBSTANCE: invention relates to the field of engineering and the production of lubricants and can be used for introduction into motor, transmission, industrial oils and greases. Anti-wear composition for lubricating oils based on oil-soluble molybdenum dialkyldithiophosphate contains molybdenum dialkyldithiophosphate with alkyl radicals containing 12 or more carbon atoms, diester of tiophthalic acid with alkyl radicals containing 12 or more carbon atoms, the starting components being taken in the following ratio, %: molybdenum dialkyldithiophosphate – 50–80, diester of tiophthalic acid – 20–50.
EFFECT: increase in the anti-wear properties of lubricating oils, as well as the stability of molybdenum dialkyldithiophosphate to hydrolysis, has been achieved.
