Abstract:
A metal working water-soluble lubricant composition comprising a water-soluble polymer compound whose counter anion is acidic phosphorus-containing compound or boric acid is disclosed. The water-soluble polymer compound is selected from the group consisting of cationic or amphoteric addition polymers, ring-opened polymers, polycondensation products and salts or quaternary ammonium salts of natural polymer derivatives having at least one basic or cationic nitrogen atom in one molecule thereof with a molecular weight of 1,000 to 10,000,000. The composition has a load resistance equal to or higher than known liquid lubricants which contain mineral oils, beef tallow etc., and shows an excellent lubricating performance when applied to a metal working surface.

Abstract:
Novel organoammonium compounds are provided, which are useful as additives for improving the antiwear and friction-reducing properties of lubricating compositions. The compound is formed by reacting a metal acid hydrate with one or more alkyl amines. Particular examples are the preparation of ditridecylammonium tungstate, di-n-octylammonium tungstate and ditridecylammonium molybdate.
Abstract:
An aqueous one step type lubricating agent for efficient cold forging, characterized in that it comprises (A) a water-soluble inorganic salt, (B) a wax and (C) a metal salt of a fatty acid in a form dissolved or dispersed in water, wherein weight ratios of solid contents are 0.60 to 0.70 for (B)/(A) and 0.1 to 0.3 for (C)/(A). The water-soluble inorganic salt can be selected from among a sulfate, a silicate, a borate, a molybdate and a tungstate. As the wax, use can be made of a synthetic wax being dispersible in water and having a melting point of 70 to 150 DEG C. As the metal salt of a fatty acid, use can be made of a reaction product of a saturated fatty acid having 12 to 26 carbon atoms with at least one metal selected among zinc, calcium, barium, aluminum and magnesium.
Abstract:
A two- or a one-step process and composition which coats metal workpiece surfaces (aluminum, copper, steel, stainless steel, etc.) with a thin lubricant film capable of allowing the metal to be deformed at room temperature. The lubricant consists essentially of polymers, dispersants, high molecular weight waxes and insoluble metallic stearates. With some ferrous surfaces, a separate coating layer is simultaneously formed (in the one-step process) or pre-formed (in the two-step process) at the metal interface, acting as a base for the lubricant. The process, after pickling in a mineral acid to remove scale and oxides, comprises the step(s) of immersing the workpiece either once or twice. The workpiece is then dried in a heated, forced air dryer.
