DEVELOPMENT OF NONFLAMMABLE HYDRAULIC FLUID
Abstract
The object of the study is the development of a waterbase hydraulic fluid which (1) yields a fire-resistant nonaqueous 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. Low-density polyethylene can be chlorophosphonated by reaction with phosphorus trichloride and oxygen. Hydrolysis and neutralization produces products which show considerable promise as thickeners. The product from 21,000- molecularweight polyethylene, neutralized to a pH of 8.0 with sodium hydroxide, produces a fluid which (1) has the desired viscosity, (2) is shear stable in tests using a Raytheon Sonic Oscillator, (3) can be rendered non-corrosive to iron, copper, silver braise, aluminum, and zinc by the addition of corrosive inhibitors, (4) has no deleterious effect on Buna N rubber, (5) is compatible with 10% synthetic sea water, (6) is non-toxic and non-irritating, and (7) appears to produce a non-aqueous residue having satisfactory flammability characteristics.
