Abstract:
Provided is a water-soluble rubricating agent for plastic working being
capable of forming a lubricating film having lubricity and seizure
resistance equal to or greater than a phosphorus-containing chemical
conversion treatment film, having excellent corrosion resistance, and
also having good film adhesion, without including phosphorus in the film.
This water-soluble non-phosphorus lubricating agent for plastic working
includes an inorganic solid lubricant as component A, a wax as component
B, and a water-soluble inorganic metal salt as component C, wherein the
mass ratio (component A/component B) of solid content for component A to
solid content for component B is 0.1 to 5, and the mass percentage
(component C/(component A+component B+component C)) of solid content for
component C to total solid content for components A, B and C is 1 to 30%.Claims:
