The objective of the study is the development of a water-base hydraulic fluid which 1 yields a fireresistant non-aqueous residue, 2 is compatible with materials of construction and sea-water contamination, 3 satisfactorily lubricates shipboard pumps, 4 presents no unusual storage or handling problems, and 5 exhibits no toxicological hazards under conditions of use. A fluid was developed which appears to have the desired properties. It contains about 20 of a thickener prepared by chlorophosphonating polyethylene 12,000 m.w. followed by hydrolysis and neutralization with potassium hydroxide. Potassium bis-hydroxymethyl phosphonate 25 and potassium molybdate 1 are added as pour depressor and corrosive inhibitor respectively. This fluid performs satisfactorily in a Vickers Vane pump run at 150F and 1000 psi and shows satisfactory viscosity and pour-point properties. Other tests are being carried out.
