Abstract Effect of the addition of modified sepiolite on the thermal oxidative stability of the surface modified sepiolite reinforced ethylene propylene diene monomer rubber (OSP/EPDM) was investigated via the orthogonal experiment L9(34). The peak temperature variation for the oxidation process of OSP/EPDM is determined by thermogravimetric and differential thermal analysis (TG-DTA). The apparent activation energy (ΔE) and reaction rate constant (KT) were acquired via oxidation reaction test of the vulcanized rubber and oxidation reaction kinetics calculation, while the oxidation induction time (OIT) was calculated according to Doyle formula, which was compared with the experimental resultsof rubber aging test. The results show that the oxidation induction time (t70) are in good agreement with the reaction rate constant K70, and the calculated results are consistent to the experimental ones, indicating that the t70 could be applied to evaluate thermal oxidative stability of OSP/EPDM.
