An aqueous lubricant, used for the plastic work of metallic material, which comprises: (A) an inorganic water-soluble salt, (B) a lubricating agent, selected from molybdenum disulfide and graphite, and (C) wax, in that the components dissolve or disperse in water, and where the concentration ratio (weight ratio) of (B) / (A) is in the range of 1.0 ~ (5.0 and (C) / (A) is 01 ~ 1.0 And a method for the process of a lubricating film on metallic material, in which this lubricating film is formed by applying the aqueous lubricant at a dry weight of 0.5 40 g / m2 An inorganic salt (A), soluble in water, it is preferably selected from the group consisting of a sulfate, a silicate, a borate, a molybdate and a tungstate.The wax (C) is preferably a natural wax or a synthetic wax, which is dispersed in water, and has a point of 70 ~ 150 degree C fusion. The aqueous lubricant can be used to impart excellent lubricity with ease to the surface of a metal, which does not have a chemical conversion layer formed. |
