Abstract:

Covalently modified silica particles were prepared by the sol-gel process from tetraethoxysilane in the presence of (2-iodo-4,4,5,5,6,6,7,7,7-nonafluoroheptyloxy)methyloxirane under the conditions of base catalysis. The friction coefficients of formulations of petroleum oil with thickeners based on modified SiO2 particles (5 and 10 wt \%) at loads of 10, 20, 30, and 60 N were determined. The formulation with the lowest thickener content under the conditions of low loads demonstrates the most pronounced decrease in the friction coefficient. The probable mechanism of the improvement of antifriction properties is the formation of friction layers based on iron compounds.
