【摘要】 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 5 5 0 >KH 846 >KH 5 90 >KH 5 6 0 ,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 10 2 >NDZ 2 0 1>NDZ 311>NDZ 40 1>NDZ 10 1;表面活性剂的改性效果优劣顺序为 :ATAC >T 40 >ABS更多还原

【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;among silane coupling agents,KH 550>KH 846>KH 590>KH 560,and amino group or phosphate group containing 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.更多还原
