Abstract

Antioxidation synergistic effects between ZnDTC and ZnDDP in a mineral base oil were investigated by the Rotary Bomb Oxidation Test (RBOT) and the Indiana Stirring Oxidation Test (ISOT). The results indicate that there is strong antioxidation synergism between the two additives. Fourier transmission infrared spectroscopy (FTIR) analyses show that the oxidation products in the tested oils simultaneously containing the two additives are much less than those in the tested oils containing a single additive and the base oil.
