DEVELOPMENT OF NONFLAMMABLE HYDRAULIC FLUID

Abstract

The development of a water-base hydraulic fluid which (1) yields a fire-resistant 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 is described. Five- pound batches of four commercial chemicals were purified by distillation. Diethyl vinylphosphonate was synthesized and polymerized to yield a polymer of 1145 molecular weight. Polyethylene grease (1800 molecular weight) was chlorophosphonated, hydrolyzed, and neutralized with sodium hydroxide to yield a water-soluble salt containing 15.5% phosphorus. Static tests showed a 10% solution of this product in water to be somewhat corrosive to steel and copper and noncorrosive to aluminum and galvanized steel.
