Abstract:
      The effect of vulcanization systems on the vulcanization characteristics，physical properties，and dynamic mechanical properties of the silica tread compounds，and vulcanization efficiencies and performance of the tires was studied.The results showed that reducing the amount of anti-scorching agent CTP，increasing the amount of accelerator DPG and using accelerator TBzTD，the vulcanization efficiency of the tread compound could be improve.While ensuring a similar crosslinking density，the physical properties and dynamic mechanical properties of the tread compound were guaranteed.Using rebound value test samples to simulate the defoaming situation of the tread compound during vulcanization，the results were consistent with the defoaming situation of the tire during vulcanization. After adjusting the vulcanization system of the tread compound to shorten the vulcanization time of the tire could reduce the degree of over sulfurization of certain components of the tire，the high-speed performance，durability，rolling resistance and dry braking performance of the tire were guaranteed or improved.
