Abstract:
    Novel cold rolling oils for steels comprise (A) 40 to 90% by weight of a monoester of an aliphatic carboxylic acid having 12 to 22 carbon atoms and an aliphatic alcohol having 1 to 12 carbon atoms, (B) 0.5 to 10% by weight of at least one of a dimer acid and a polymerized acid of a higher aliphatic unsaturated acid having 16 to 20 carbon atoms, (C) 2 to 40% by weight of a polyester having a molecular weight of 750 to 7500, or 10 to 25% by weight of fat and fatty oils, and (D) 0.1 to 10% by weight of a polymer compound having nitrogen atoms in a molecule having a molecular weight of 1,000 to 1,000,000 such as a homopolymer or copolymer of monomers of the following general formula (I) in which R1 represents H or CH3, R2 and R3 independently represent H or an alkyl group having 1 to 3 carbon atoms. The cold rolling oils for steels have good lubricity, surface cleanability with excellent heat resistance and oxidative stability.
