Silica Gel Plastic Greases Resistant to Corrosive Media

Abstract

Two greases were synthesized. The dispersion medium for the first grease are polymers of trifluorochloroethylene which boil when the range of 140- 200C at 10 torr, and for the second grease -- no. 30 synthetic oil. Used as thickeners for these greases were special synthesized organosilica gels - alkylsilyl derivative, and in alkyl alcoxysilyl derivative of silicic acid gel. Treated with the thickeners, these two greases were found to be exceedingly moisture resistant; they can withstand boiling in water for 100 hr without the separation of the dispersion medium from the thickener; they also possess high chemical and colloidal stability and do not cause corrosion of metal, and do not melt.
