Abstract:
      The thermal-oxydative aging properties were determined on the NR vulcanizates filled with 3 types of clays which were treated by reductant and strong acid and different metal compounds were added in.The results showed that the aging properties of clay-filled vulcanizates were influenced by the metal components in clay in order of Co>Cu>Fe>Mn；the change of iron content in a certain range did not have significant effect on the aging properties of clay-filled vulcanizate；and the aging properties of clay-filled vulcanizate were not in correspondence with the content of harmful metals in clay because the metal components in clay existed in different forms.
