Estimating the term…
Abstract
A water-based lubricant is provided that includes a phthalate ester in an amount of about 2% to about 20% based on the weight of the final composition and water in an amount of about 60% to about 93% based on the weight of the final composition. Also provided are a method of making the water-based lubricant and a method of metalworking using the water-based lubricant.
Claims10
A method of making a water-based lubricant composition comprisng the steps of
- providing waters
- providing a phthalate ester having at least one terminal hydroxyl group, wherein the phthalate ester is a reaction product that has been formed by
- a. reacting phthalic anhydride with at least one alcohol, wherein the alcohol is either
- (1) a fatty alcohol having the formula ROH, where R is C4 to C22 branched or linear;
- or
- (2) a polyol having the formula HO—R1—OH, wherein R1 represents:
- (a) alkylene groups of 2 to 10 carbon atoms;
- (b) —CH2—R2 —CH2— wherein R2 represents:
- (c) —(R3O)n—R3—
- where each R3 independently is an allylene group of 2 to 4 carbon atoms, and n is an integer of from 1-200;
- and
- b. reacting the product resulting from the phthalic anhydride alcohol reaction with an alkoxylating agent to produce the phthalate ester reaction product having at least one terminal hydroxyl group;
- and
- mixing the phOhalate ester and water.
