Definitions

• This invention relates to aqueous base, metal-working lubricating compositions. More particularly, it relates to extreme pressure water-base metal cutting fluids for use i in cutting, drilling, reaming, grinding and other machining and forming operations of ferrous and non-ferrous metals.
• water-base cutting fluids possess good cooling properties, but that they lack the lubricating and extreme pressure properties of oil base lubricants.
• oil base lubricants are inferior coolants and cause odor, smoke, and staining.
• the art discloses various water-base cutting fluids, most of which lack extreme pressure properties. Because of the multiplicity of additives which the majority of such fluids contain, they are unstable, tend toward phase separation and foaming, and are diflicult and expensive to prepare.
• materials commonly used in such water solutions are 18.11 alkali, e.g., borax, sodium carbonate or trisodium phosphate, an anti-rust agent, e.g., sodium nitrite or triethanolamine, and wetting, buffering and solubilizing agents.
• the metal wetting additives may be water-soluble non-ionic compounds such as a reaction product of alkylphenol-ethylene oxide or a block polymer of ethylene oxide and propylene oxide sold commercially under the trade name of Plu-ronics (Wyandotte Chemical Company).

• the final water base fluid should have a pH between 8 and 11, preferably from about 9 to about 10. This is accomplished by addition of excess base (alkali hydroxide, e.g., NaOH) used in forming the phosphonate salts.
• the combination of the above essential additives functions in a particular manner and produces an outstanding metal working fluid.
• the normal alkali metal chloro C alkyl phosphonate functions as an extreme pressure and load carrying agent.
• the alkanolamine carboxylate decreases bearing wear and grease loss.
• the free alkanolamine inhibits metal corrosion, particularly of ferrous metals, without producing any undesirable side effects,
• lidihlid FIC clud-e sodium, potassium and/ or lithium salts of said acid

Preferred amine salts are triethanolamine oleate, triethanol amine ricinoleate and mixtures thereof.
• the water-miscible heterocopolymer polyalkylene oxide fluids enhance the cutting performance of the compositions of the persent invention by enhancing metal wetting.
• the above oxides are heterocopolymers of dissimilar alkylene oxides such as copolymer ethylene oxide and 1,2 propylene oxide [poiy(oxyethylene-1,2-oxypropylene)glycol], as well as monoethers and monoesters thereof, preferably at oxide ratios of from :25 to 10:90 ethylene oxide to LIZ-propylene oxide, and molecular weight of from about 250 to about 1500.
