Abstract
A hybrid lubricant in which a stabilized, colloidal dispersion of solid lubricant particles (PTFE) is uniformly dispersed in a fluid lubricant carrier including a small amount of halocarbon oil. When the hybrid lubricant is diluted with a major amount of a conventional fluid lubricant, it functions in the environment of rubbing surfaces and reacts therewith to develop a layer of solid lubricant on these surfaces whereby the surfaces then have the benefit of both solid and fluid lubrication, thereby minimizing friction under all operating conditions regardless of their severity.
Claims20
A hybrid lubricant in a minor amount which is dilutable by a major amount of a conventional fluid oil lubricant to provide a working lubricant applicable to metal rubbing surfaces, such as those found in internal combustion engines or other mechanisms having rotating or moving parts and functioning in the environment of the rubbing surfaces to develop a layer of solid lubricant on these surfaces, said hybrid lubricant comprising:
- A. a colloidal aqueous dispersion of polytetrafluoroethylene particles;
- B. a neutralizing agent added to said dispersion in an amount stabilizing the dispersion to prevent agglomeration of the particles;
- C. a fluid oil lubricant carrier intermingled with the stabilized dispersion to form an emulsion therewith, said emulsion including a dispersant to effect homogenization thereof;
- and
- D. a wetting agent added to said emulsion having an affinity for the rubbing surfaces to render the surfaces conductive to impregnation by said particles and to the fusion thereof to said surfaces to develop a solid lubricant layer thereon formed of polytetrafluoroethylene whereby said surfaces have the benefit of both solid and fluid oil lubrication.
