系统研究线形中乙烯基聚丁二烯橡胶(L-MVBR)、星形中乙烯基聚丁二烯橡胶(S-MVBR)、线形1,4-1,2-立构二嵌段中乙烯基聚丁二烯橡胶(L-B-MVBR)和星形1,4-1,2-立构二嵌段中乙烯基聚丁二烯橡胶(S-B-M VBR)的硫化反应和硫化胶的性能,考察了炭黑在不同中乙烯基聚丁二烯橡胶(MVBR)中的分散性,研究结果发现L-B-MVBR同时具有最佳的抗湿滑性和耐磨性,两种性能可达到较佳的平衡,以四氯化锡为偶联剂制备的S-MVBR具有最佳的炭黑分散性。 |
英文摘要: |
The vulcanization of four kinds of modified MVBRs,such as L-MVBR,S-MVBR,L-B-MVBR and S-B-MVBR,and the properties of their vulcanizates were studied in detail,and the dispersion of carbon black in different MVBRs was investigated.The results showed that the optimal balance between the wet skid resistance and the wear resistance was obtained for the L-BMVBR;and the best black dispersion was obtained for the S-MVBR prepared with SnCl4 as the coupling agent. |
