| Abstract: |
| The influence of the surface modification for silica with 10 types of coupling agents and 3 types of surfactants respectively on the physical properties of NR/BR vulcanizate was investigated.The results showed that the positive effects of different surface modifiers on the physical properties of NR/BR vulcanizate were as follows:silane coupling agent>titanate coupling agent>surfactant；amongsilane coupling agents，KH-550>KH-846>KH-590>KH-560，and amino group or phosphate groupcontaining coupling agents had better aging properties；among titanate coupling agents，NDZ-311w>NDZ-102>NDZ-201>NDZ-311>NDZ-401>NDZ-101；and among surfactants，ATAC>T-40>ABC. |
