Abstract

PURPOSE:To provide an aqueous lubricating oil composition which has low foaming property and is used in a water-soluble hydraulic oil, a heating medium, a metal processing oil or the like, comprising a polyoxyalkylene glycol compound. CONSTITUTION:The aqueous lubricating oil composition is based on a mixed liquid comprising 4-80wt% polyoxyalkylene glycol compound shown by formula I or II [wherein R1 and R2 are H, 1-4C alkyl, X is O, N, Y is 1-4C alkylidene, AO is 3-4C oxyalkylene, EO is oxyethylene, (n) is 1 or 2, (a) is 10-500, (c) is 1-50, (b)/(a+c) is in a range of 25/75-95/5, a group enclosed by [ ] is one formed by subjecting (a) mole of AO and (b) mole of EO to random polymerization and thereafter graft-polymerizing (c) mole of AO to a terminal of the resulting polymer], 20-96wt% water and 0-50wt% water-soluble org. solvent such as glycols or glycol ethers. Said composition reduces friction wear of a pump, does not yield sludge, has a transparent appearance after use and is excellent as a hydraulic oil.
