Abstract
PURPOSE:A water-glycol working fluid suitable for high-pressure hydraulic system, having improved metal abrasion resistance and antifoaming properties and high water-solubility and stability, and containing specific amounts of a higher unsaturated and saturated fatty acids and an alkali metal. CONSTITUTION:A working fluid containing (A) 0.25wt% or more 16-18C higher unsaturated fatty acid, (B) 6wt% or more 10-14C higher saturated fatty acid and (C) and alkali metal in an amount of the neutralization equivalent or more of the fatty acids in the components (A) and (B). Oleic acid (potassium salt) is preferred as the component (A), and lauric acid (potassium salt) is preferred as the component (B). The working fluid is preferably neutralized to show the final pH of 9-11.
