Abstract
A lubricant concentrate for use in metal processing comprises a sulfur compound such as a sulfurized olefin or sulfurized mineral oil and an ester prepared from a fatty acid having 12 to 40 carbon atoms or the dimer thereof or a polyalkenylsuccinic acid or anhydride and a hydroxyl-containing amine.
Claims22
An emulsifiable lubricant composition comprising, in the neat form, a sulfurized olefin or sulfurized mineral oil and from about 0.5% to about 95% by weight thereof of
- (a) the reaction product made by reacting a C.sub.12 to C.sub.20 monocarboxylic acid or a dimer thereof or an alkenylsuccinic anhydride or acid wherein the alkenyl is derived from a mixture of C.sub.16 -C.sub.28 olefins with (1) a hydroxyalkylamine containing 2 to 100 carbon atoms, or (2) a hydroxypolyetheramine of the formula ##STR2## wherein R is a C.sub.8 to C.sub.18 hydrocarbyl group and x is from 1 to 50, R' is a --(CH.sub.2 CH.sub.2 O).sub.x CH.sub.2 CH.sub.2 OH group or a --(CH.sub.2 CH.sub.2 CH.sub.2 O).sub.x CH.sub.2 CH.sub.2 CH.sub.2 OH group and R' is selected from R and R";
- or
- (b) the reaction product of (a) (2) and a rosin soap;
- or
- (c) the product of (a) or (b) and from about 0.5% to about 15% by weight thereof of a C.sub.2 to C.sub.10 monocarboxylic acid.
A method of metal working comprising applying to the metal a lubricant composition comprising, in the neat form, a sulfurized olefin or sulfurized mineral oil and from about 0.5% to about 95% by weight thereof of
- (a) the reaction product made by reacting a C.sub.12 to C.sub.20 monocarboxylic acid or a dimer thereof or an alkenylsuccinic anhydride or acid wherein the alkenyl is derived from a mixture of C.sub.16 -C.sub.28 olefins with (1) a hydroxyalkylamine containing 2 to 100 carbon atoms, or (2) a hydroxypolyetheramine of the formula ##STR3## wherein R is a C.sub.8 to C.sub.18 hydrocarbyl group and x is from 1 to 50, R' is a --(CH.sub.2 CH.sub.2 O).sub.x CH.sub.2 CH.sub.2 OH group or a --(CH.sub.2 CH.sub.2 CH.sub.2 O).sub.x CH.sub.2 CH.sub.2 CH.sub.2 OH group and R' is selected from R and R";
- (b) the reaction product of (a) (2) and a rosin soap;
- or
- (c) the product of (a) or (b) and from about 0.5% to about 15% by weight thereof of a C.sub.2 to C.sub.10 monocarboxylic acid.
