AQUEOUS LUBRICANT FOR PLASTIC WORKING OF METAL MATERIAL AND HAVING SUPERIOR GAS CLOGGING RESISTANCE AND POST-MOISTURE ABSORPTION WORKABILITY

WIPO Patent Application WO/2015/005142

A1

[Problem] The present invention resolves the problems of conventional technology and has as the objective the providing of an aqueous lubricant that is for plastic working of a metal material and having superior gas clogging resistance, post-moisture absorption workability, and high workability at least equivalent to that of conventional applied aqueous lubricants and lubrication processing such as zinc phosphate + soap processing. [Solution] This aqueous lubricant for plastic working of a metal material is characterized by containing, in an aqueous medium: (A) a polymer, and/or a salt thereof, containing a carboxylic acid or a derivative thereof as a constituent monomer; (B) a silicon or phosphorus oxo acid of tungsten or a condensate and/or salt thereof; (C) the hydroxide of an alkali metal; and (D) a lubricating component. The aqueous lubricant for plastic working of a metal material is further characterized in that the solid fraction weight ratio (A)/[(A)+(B)+(C)+(D)] of component (A) and component (B), component (C), and component (D) is 0.05-0.4.
