DTIC AD0750986: Silica Gel Plastic Greases Resistant

More Book Details

Description of the Book:

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
