PURPOSE:To provide a lubricant compsn. which has excellent lubricating performance and rust-proofness, is suitable for use in working metallic sheets and allows lubricating treatment and rust proofing treatment to be carried out simultaneously, by emulsifying wax contg. hydrocarbon wax, a surfactant and chromic acid in water. CONSTITUTION:A solid component contg. 30-80wt% wax (e.g. carnauba wax or paraffin wax) contg. at least 5% hydrocarbon wax, 10-40wt% surfactant (e.g. polyoxyethylene nonylphenol ether or sorbitan alkyl ether) and 1-40wt% chromic acid, is prepd. 30-2wt% said solid component is emulsified in 70-98wt% water to obtain the desired lubricant compsn. having rust-proofness. The compsn. is suitable for use in working (e.g. drawing) metallic sheets, and rust-proofing treatment after working is not necessary. |
