Abstract
A water-soluble metal-working lubricant composition comprising as essential components thereof PA0 (a) one or more polyetherpolyols having molecular weights of 200 to 100,000 and obtained by adding alkylene oxides to either one or more of compounds selected from PA1 (1) polyalkylenepolyamines and derivatives thereof, PA1 (2) alkyl- and alkylaryl-amines and derivatives thereof and PA1 (3) carboxylic acid amides and derivatives thereof; and PA0 (b) one or more compounds selected from phosphoric acid compounds and boric acid. Incorporation of a specific polyetherpolyol compound together with phosphoric acid compound or boric acid serves as alternative to conventional liquid oil-base lubricant with mitigating drawbacks such as poor stability of emulsions, fouling of surfaces, difficulty in waste water, etc., which are inherent in conventional lubricants.
