摘要： A substantially water-free, emulsion type liquid lubricant for metal forming which comprises:
(a) a lubricating oil, (b) at least one phosphoric acid ester from the group represented by the general formula:
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 wm, 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 (1) or a die (3) 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.

摘要： A magnetic recording medium (1) comprising a non-magnetic substrate and a magnetic layer and a protective layer which are formed on the non-magnetic substrate in that order, wherein a substance(s) as a single component or a plurality of components, which constitute a liquid continuously supplied to the surface of said protective layer, are adsorbed on or react with the surface of said protective layer to form a lubricating film (3) having low frictional properties and low wearing-out properties. The present invention can realize negligible friction and wear resistance even in severe sliding at a very slightly kept-off or completely contacted state by continuous supply of a liquid lubricant (3) prepared by adding a fluoro compound and an extreme pressure agent or an oiliness agent to a solvent to the surface of a disc, and can provide a magnetic recording reproducer having excellent sliding-resistant characteristics.
