DEVELOPMENT OF NONFLAMMABLE HYDRAULIC FLUID
Abstract
The object of the study was the development of a waterbase 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. Lowdensity polyethylene can be chlorophosphonated by reaction with phosphorus trichloride and oxygen. Hydrolysis and neutralization with potassium hydroxide yields products which satisfactorily thicken water and which have satisfactory fire-resistant properties. Potassium salts of low-molecular-weight phosphonic acids are satisfactory pour depressors for these fluids. Potassium chromate and potassium molybdate are effective corrosion inhibitors. The most promising formula is: 27% thickener, 30% potassium bis-hydroxymethylphosphonate, 2% potassium molybdate, and 41% water.
