偶联剂NXT对白炭黑补强NR性能的影响

研究硅烷偶联剂NXT改性白炭黑填充NR的硫化特性、动态力学性能以及物理性能，并与TESPT进行对比。结果表明，与TESPT相比，加入NXT的胶料具有较好的抗焦烧性能和耐热老化性能，两者硫化胶的动态力学性能相当；NXT的用量以6份为佳。;The effect of the coupling agent NXT on the curing behavior，dynamical properties and physical properties of silica-filled NR compound was investigated and compared to TESPT.The results showed that NXT gave silica-filled NR compound better scorch safety and heat aging resistance，and gave similar dynamic mechanical properties to vulcanizate；and the optimal addition level of NXT was 6 phr
