Abstract
A cold-rolling lube oil for metallic materials is composed of (a) 40-90 wt. % of a monoester of a specific aliphatic carboxylic acid and a particular aliphatic alcohol, (b) 0.5-10 wt. % of at least one of dimer acids and polymer acids of certain unsaturated higher fatty acids, (c) 10-25 wt. % of a fats and fatty oils, or 5-70 wt. % of an ester obtained by reacting remaining carboxyl or hydroxyl groups of a specific polyester with a specific alcohol or fatty acid, (d) 0.3-10 wt. % of a phenol-type antioxidant, and (e) 0.3-10 wt. % of a sulfur-type antioxidant.
Claims11
A water emulsifiable cold-rolling lube oil for metallic materials comprising:
- (a) 40-90 wt. % of a monoester of an aliphatic carboxylic acid having 12-22 carbon atoms and an aliphatic alcohol having 1-12 carbon atoms;
- (b) 0.5-10 wt. % of at least one of dimer acids and polymer acids of unsaturated higher fatty acids having 16-20 carbon atoms;
- (c) 10-25 wt. % of a fat or fatty oil, or 5-70 wt. % of an ester having a molecular weight of 750-7500 which is obtained by reacting the remaining carboxyl or hydroxyl groups or a polyester, which in turn is obtained by heating and condensing at least one dimer acid or polymer acid of an unsaturated higher fatty acid having 16-20 carbon atoms and a polyol, with an alcohol having 1-22 carbon atoms or a fatty acid having 12-22 carbon atoms;
- (d) 0.3-10 wt. % of a phenolic antioxidant;
- and
- (e) 0.3-10 wt. % of a sulfur containing antioxidant.
