中文摘要: |
采用反应加工方法,以氢化钠(NaH)作活性剂、三乙基氯硅烷(Et3SiCl)作改性剂制备硅烷化改性乳聚丁苯橡胶(Si-ESBR),并对其动态性能进行研究。Si-ESBR最佳改性条件为:ESBR 50g,NaH 0.04mol,Et3SiCl 0.04mol,加人NaH后的反应时间 15min,加人Et3SiCl后的反应时间 15min,反应温度 80℃。ESBR硅烷化改性后胶料的Payne效应明显降低,填料的网络化效应得到改善,动态能量损耗减小。 |
英文摘要: |
The silane modified ESBR(Si-ESBR) was prepared by reaction processing method and using NaH as activating agent and Et3SiCl as modifier,and the dynamic properties of Si-ESBR were studied.The optimum reaction condition was as follows:ESBR 50g,NaH 0.04mol,Et3SiCl 0.04 mol,reaction time after adding NaH 15 min,reaction time after adding Et3SiCl 15 min,reaction temperature 80 ℃.With the modification,the Payne effect of Si-ESBR decreased significantly,the filler network improved effectively,and the dynamic energy loss decreased. |
