用吸附性促进剂NMBS制备的NR/蒙脱土纳米复合材料的结构与性能研究

试验研究用吸附性促进剂NMBS制备的NR/蒙脱土纳米复合材料的结构和性能，并与用常规促进剂CZ制备的纳米复合材料进行对比。结果表明，在NR/蒙脱土或NR/有机蒙脱土中加入促进剂NMBS，胶料的活化能下降；而加入促进剂CZ后胶料的活化能明显提高。在两种促进剂体系胶料中加入8份有机蒙脱土，硫化胶中有机蒙脱土的层间距相同；促进剂NMBS体系硫化胶的交联密度明显增大，物理性能总体提高（有机蒙脱土的适宜用量为2～10份），而促进剂CZ体系硫化胶的交联密度和物理性能均变化不大。;The structure and properties of NR/montmorillonite (MMT) nano-composite prepared with absorptive accelerator NMBS were experimentally investigated and compared to those with normal accelerator.The results showed that the activation energy of compound decreased by adding NMBS into NR/MMT or organomontmorillonite (OMMT)，in contrast，the activation energy increased significantly by adding accelerator CZ.The galleries between layers of OMMT in vulcanizate were the same by adding 8 phr OMMT in NR compound with NMBS or CZ；and the crosslink density of the vulcanizate with NMBS increased and its comprehensive physical properties also improved，but the crosslink density and physical properties of the vulcanizate with CZ changed little
