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.

Abstract

The effects of a new multi-functional vulcanization agent WL207 on the co-vulcaniza-tion,dynamic mechanical properties and physical and mechanical properties of NR/ESBR blends were studied,and analyzed by scanning electron microscopy(SEM),dynamic mechanical thermal proper-ties(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 a-chieved 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.
