白炭黑表面改性对NR/BR硫化胶性能的影响

研究了10种偶联剂和3种表面活性剂改性白炭黑后对NR/BR硫化胶性能的影响。试验结果表明，不同表面改性剂改性白炭黑后对NR/BR硫化胶物理性能的影响程度大小顺序为:硅烷类偶联剂>钛酸酯类偶联剂>表面活性剂。其中硅烷类偶联剂的改性效果优劣顺序为:KH-550>KH-846>KH-590>KH-560，带胺基和磷酸酯基团的偶联剂具有较好的抗老化作用；钛酸酯类偶联剂的改性效果优劣顺序为:NDZ-311w>NDZ-102>NDZ-201>NDZ-311>NDZ-401>NDZ-101；表面活性剂的改性效果优劣顺序为:ATAC>T-40>ABS。;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
