Since synthetic oils of high viscosity are used, how to suppress oil separation and syneresis has become an important technical issue.

If the base oil leaks out or diffuses, it causes problems such as poor contact, fogging of lenses and the like, and contaminating resin parts, and eventually stops the performance of precision equipment itself. Serious troubles can occur.

散性フッ素系グリース組成物の重要なポイントとなる。BEST MODE FOR CARRYING OUT THE INVENTION The non-diffusible fluorine-based grease composition according to the present invention has its main constituents composed of fluorine oil and silicone oil. These synthetic oils do not dissolve in each other, but if one of the components is a grease composition, the thickener material acts as an emulsifier and is incorporated into the grease-like material. Considering the case where silicone oil is added to the fluorine grease, the PTFE powder used as a thickener component of the fluorine grease acts as a medium to take in the silicone oil, emulsify it, and form a somewhat hardened grease-like substance. How to maintain the emulsified state here is an important point of the non-diffusible fluorine-based grease composition of the present invention.

流出しようとするフッ素オイルを阻止する役目を果た
す。Another important point of the non-diffusible fluorine-based grease composition according to the present invention is a difference in surface tension. When the viscosity is the same between the fluorine oil and the silicone oil, the silicone oil has a lower surface tension. If this relationship is used, only a small portion of the silicone component will bleed out from the mixed state on the grease surface, but the opposite effect will be exerted to maintain the emulsification, and further bleeding of the silicone oil will stop. . Some of the silicone oil that bleeds out on the surface quickly adheres to greased metal surfaces and plastic materials, and serves to prevent fluorine oil from escaping later.
