Abstract:
A new water-base lubricant composition has been discovered which is uniquely suitable for elevated temperature metal forming operations. The water-base lubricant invention herein generally comprises, about 1% to about 40% by weight of a polycarboxylic acid salt reaction product, such as trimellitic acid and an alkali metal or an alkali earth metal hydroxide, such that the pH of the composition is about 6.5 to about 10; about 0.1% to about 12% by weight of a water dispersible thickening agent; and the balance water. The water-base lubricant may also include extreme pressure additives, performance enhancers, and biocidal agents. Also disclosed is a process for using the above-described water-base lubricant composition.

Abstract:
This invention is directed to borated amine salts of dihydrocarbyl monothiophosphoric acids, and to lubricating and functional fluid compositions containing said borated amine salts. The lubricating and functional fluid compositions have improved extreme pressure properties and high temperature stability.The borated amine salts of the invention may be characterized by the formula ##STR1## or mixtures thereof wherein R.sup.1 and R.sup.2 are each independently hydrocarbyl groups containing from 1 to about 30 carbon atoms. In one preferred embodiment, the amine salts are derived from hydroxyhydrocarbyl amines.The lubricating and functional fluid compositions may contain, in addition to the borated amine salts, at least one nitrogen-containing composition prepared by the reaction of a hydrocarbon-substituted succinic acid-producing compound with at least about one-half equivalent, per equivalent of acid-producing compound, of an amine containing at least one hydrogen attached to a nitrogen atom. The lubricating compositions of the present invention are particularly useful as lubricating oils, functional fluids and greases.
