Abstract
A halocarbon oil composition suitable for use as a hydraulic fluid and lubricant in those applications in which hydrocarbon oils constitute a fire hazard or a contaminant because of their reactive properties. The composition is formed by a chemically-inert halocarbon oil having PTFE solid lubricant particles dispersed therein, the particles being in the micron range. Also included is a fluorochemical surfactant having foam-producing properties in an amount insufficient to generate foam in the context of the inherent non-foaming characteristics of the particles, the surfactant acting to enhance the lubricity of the oil and to stabilize the PTFE dispersion therein.
Claims6
A non-reactive halocarbon oil composition suitable for use as a hydraulic fluid and as a lubricant, the composition including a dispersion in the oil of solid lubricant particles having inherent defoaming characteristics, the particles being in the micron size range, and a fluorochemical surfactant possessing foam-generating characteristics in an amount insufficient to generate foam but sufficient to stabilize the dispersion and enhance the lubricity of the oil, said surfactant is a nonionic surfactant belonging to the chemical class of fluorinated alkyl esters.
