    摘要： A substantially water-free, emulsion type liquid lubricant for metal forming which comprises:(a) a lubricating oil,(b) at least one of phosphoric acid esters represented by the general formula: ##STR1## wherein R is alkyl, alkylalkenyl or aryl; n is an integer of 1 to 2, and (c) an emulsifying agent,an average particle size of the phosphoric acid ester being 0.3 to 120 .mu.m, can form a lubricating film having distinguished heat resistance and lubricating properties by virtue of the heat generated by deformation and friction during the metal forming only by wetting the surface of a metallic workpiece or a die or both with the lubricant and work effectively for preventing galling, and thus parts with a high reduction of area or parts of complicated shapes can be readily formed.A lubricating film having a lubricating effect equivalent to that of the conventional phasphate film can be simply obtained, greatly contributing to reduction in product cost.An emulsion type liquid lubricant having a prolonged emulsion stability can be prepared through emulsification with a high speed mixer having a stirring blade with wiremesh-like fine perforations, and thus articles or parts with uniform quality can be formed.
