DEVELOPMENT OF NONFLAMMABLE HYDRAULIC FLUID

Abstract

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.
