AQUEOUS LUBRICANT, METAL MATERIAL, AND METAL PROCESSED ARTICLES

Document Type and Number:

WIPO Patent Application WO/2016/185876

Kind Code:

A1

Abstract:

[Problem] To provide an aqueous lubricant for metal material deformation processing that has excellent long-term chemical stability and also makes it possible to form a lubricating film having excellent lubricity (moisture absorption resistance) in high-humidity environments and seizing resistance in complex metal processing; a metal material having a lubricating film formed from the aqueous lubricant on the surface; and metal processed articles obtained by molding the metal material. [Solution] The above problem can be solved by using an aqueous lubricant for metal material deformation processing obtained by blending an aliphatic polycarboxylic acid having 5-8 carbon atoms and solubility in 20°C water of 10 g/100 mL or higher and an alkaline earth metal compound in water or by dissolving or dispersing an alkaline earth metal salt of the aliphatic polycarboxylic acid in water.
