摘　　要：研究了新型多功能硫化助剂WL207对NR/ESBR并用胶共硫化、动态力学性能以及物理机械性能的影响,并通过扫描电子显微镜(SEM)、动态力学热性能(DMA)和差示扫描量热(DSC)等进行分析。结果表明,多官能团的结构特征赋予WL207交联与促进作用,与传统硫黄硫化体系相比,较好地实现了NR/ESBR共硫化,硫化胶抗湿滑性、物理机械性能优异,填料与橡胶间的相容性好;WL207用量为4.0份时,NR/ESBR并用胶的综合性能最佳。The effects of a new multi-functional vulcanization agent WL207 on the co-vulcanization,dynamic mechanical properties and physical and mechanical properties of NR/ESBR blends were studied,and analyzed by scanning electron microscopy(SEM),dynamic mechanical thermal properties(DMA),and differential scanning calorimetry(DSC).The results showed that the structural characteristics of multifunctional groups gave WL207 with both crosslinking and promoting effects.Compared with the traditional sulfur vulcanization system,the NR/ESBR co-vulcanization was achieved well,and the vulcanized rubber had excellent wet skid resistance,physical and mechanical properties,and good compatibility between fillers and rubber.When the dosage of WL207 was 4.0 phr,the comprehensive performance of NR/ESBR blends was the best.
