PURPOSE:To obtain the title lubricant having excellent antiseizing property, by blending poly-2-ethylhexyl acrylate and/or polylauryl methacrylate with an oiliness improver which is liquid at room temp. and compatible with the esters. CONSTITUTION:Poly-2-ethylhexyl acrylate and/or polylauryl methacrylate (A) are blended with a diluting oil composed of at least one oiliness improver which is liquid at room temp. and compatible with component A to obtain an oily lubricant for cold plastic working of a metallic material. Specific examples of component B include purified lard, oleic acid, phosphate, hindered ester, isostearic acid, and 18C satd. higher alcohol. Since the oily lubricant thus obtd. is free from any extreme-pressure additive and other substances which are highly reactive, it exhibits no corrosive action against metallic materials. |
