Lubricant composition for lubricating homocinetic joints and/or connections of cars comprises base oil, alicyclic diurea, molybdenum dithiocarbamate, zinc dithiophosphate, and antimony dithiocarbamate

摘要

A lubricant composition comprises a base oil; 11-16.5 wt. % alicyclic diurea of specified formula; 1-5 wt.% molybdenum dithiocarbamate; 0.5-4 wt.% zinc dithiophosphate; and 1-5 wt.% antimony dithiocarbamate. Lubricant composition comprises a base oil; 11-16.5 wt.% alicyclic diurea; 1-5 wt.% molybdenum dithiocarbamate; 0.5-4 wt.% zinc dithiophosphate; and 1-5 wt.% antimony dithiocarbamate. The alicyclic diurea is of formula (I). Preferred Features: The alicyclic diurea is obtained by reacting diphenylmethane-4, 4'-diisocyanate and a cyclohexylamine. The base oil has a viscosity of 1.45-16.5 cm<2>/s (cSt) at a temperature of 100 deg C. The zinc dithiophosphate is present in an amount of 1.5-3 wt.%.
