LUBRICATING COMPOSITION Russian patent published in 1998 - IPC

FIELD: petrochemistry, more particularly, ecologically safe lubricating composition for coal, textile, food and petrochemical industries. SUBSTANCE: present invention describes ecologically safe lubricating composition. The claimed composition comprises (wt %): 10.0-50.0 ethylene-propylene oxide block copolymer with molecular weight of 1000-15000; 5.0- 15.0 polyoxyehtylene oxide with molecular weight of 400- 4000; 0.5-5.0 boric ether of oxyalkylated oxygen containing compound; 0.1-1.0 copper napthenate; 0.5-5.0 triethanol amine not higher than 1.0 oxypropylated alcohol; 0.01-1.0 ethylene oxide-propylene oxide block copolymer with molecular weight of 10.000; and the water balance. The claimed lubricating composition is novel in that it comprises boric ethers of oxypropylated alcohols and ethylene-propylene oxide block copolymers. EFFECT: improved antifriction, antiwear and anticorrosion properties of the lubricating composition. 2 cl, 2 tbl
