LUBRICANT FOR COLD STRAIN OF METALS Russian patent published in 2003 - IPC

FIELD: cold strain of metals; process lubricants used for cold strain of metals; possibly, drawing of metals and articles out of them, including strips, pipes, wire out of carbon and alloy steels and alloys, non-ferrous metals and their alloys with high requirements to quality of treated surface. SUBSTANCE: the aim of lubricant usage is reduction of quantity of such defects as marks and scores up to their complete disappearance, low degree of surface roughness, increased corrosion resisting protection, possibility of usage for wide range of metals. Lubricant for cold strain of metals contains product of condensation of triethylene glycol with oleic and adipic acids in the catalytic presence of natural sulfur and tributyl phosphate, static copolymer of ethylene oxide and propylene oxide, surface-active substance of mixed type, benazol = and additive B15/41 under regulated relationship of components. EFFECT: possibility of lubricant usage for treatment of wide range of metals, including carbon and alloy steels and their alloys; increased quality of surface of articles. 1 tbl
