摘要:
The present invention relates to a metal processing lubricant comprising a cationic compound obtained by neutralizing a condensation product between a specific aliphatic dicarboxylic acid and a specific aliphatic basic nitrogen compound with a phosphorus oxy acid or a derivative thereof.The lubricant of the present invention is water-soluble and excellent in lubricating property, and the change of the lubricating property is slight and degradation of the oiling component is reduced. Accordingly, the industrial value of the lubricant of the present invention is very high.

A metal-working oil composition comprises as essential components thereof (a) one or more lube-oil components selected from the group consisting of oils, fats, mineral oils and fatty acid esters; and (b) one or more compounds selected from the group consisting of acidic phosphoric acid salts of aliphatic, alicyclic and aromatic amines each of which has 4 to 22 carbon atoms and quaternary ammonium salts formed from aliphatic or aromatic amines, each of which has 4 to 22 carbon atoms, and acidic phosphoric acids; and (c) a non-ionic surfactant.Incorporation of a specific amine compound together with a non-ionic surfactant permits, owing to the protective colloidal function of the compounds, stable dispersion of the lube-oil component as large droplets in water and hence the resulting dispersion enjoys good circulation stability and withstands severe machining conditions.
