摘要
研究了废旧轮胎热解炭黑(简称:热解炭黑)与二氧化硅(SiO_2)在丁苯橡胶中的应用情况,考察了二者不同配比对丁苯橡胶混炼胶的动态力学性能、门尼粘度、硫化特性以及硫化胶力学性能、磨耗性能、导电性能的影响。结果表明,加入SiO_2可使混炼胶Payne效应增强,粘度升高,硫化时间延长;当热解炭黑/SiO_2配比为50/10和45/5时,硫化胶拉伸强度和撕裂强度均最优;配比为50/5时耐磨性能最好;随着填料总用量的增大,硫化胶导热性能升高。
Application of combination of SiO2 and carbon black pyrolyed with waste tires to SBR was researhed.The effects of different compounding ratioes of SiO2 and the pyrolytic carbon black on dynamic mechanical properties,Mooney viscosity,curing characteristics,mechanical properties,abrasion resistance and electrical conductive were discussed.The results showed that the Payne effect was increased by adding SiO2,the viscosity rose,the curing time was prolonged.The tensile strength and the tear strength were optimal when the compounding ratioes of the pyrolytic carbon black and SiO2 were 50/10 or 45/5.The wear resistance was the best when the compounding ratioes was 50/5.The thermal conductivity was enhanced with the increase of total amount of fillers.
