Abstract:
      Two kinds of all steel radial tires (TBR), with the same model, were selected from domestic and foreign brands respectively in this paper. And then the reasons for the initial damage of the tire belt compounds were investigated from the micro level by using scanning electron microscope (SEM). Furthermore, the effects of common ZnO and activated ZnO on the mechanical and high-temperature fatigue properties were discussed according to the results of SEM analysis. The results showed that theSmicroscaleSZnO remained in the compounds was the main cause to initiate the early damage of TBR belt vulcanizates for the domestic tires. The activated ZnO can be dispersed with nanoscale and high uniformity in rubber matrix, and then its mechanical and high-temperature fatigue properties were obviously superior to that of common ZnO.
