| 摘 要： | 在变外力作用下,填充橡胶的动态模量会随着应变的增加而急剧下降的现象称为Payne效应。研究填充橡胶的Payne效应可以保证橡胶制品在使用过程中的安全性和可靠性,同时获得具有良好力学性能的橡胶制品。文中通过胶乳-双辊连用法制备了炭黑/天然橡胶复合材料(RCB)、碳纳米管/天然橡胶复合材料(RCNT)和石墨烯/天然橡胶复合材料(RGE)。扫描电镜和透射电镜图像显示,该方法可以将填料均匀分散在橡胶基体中。Mooney-Rivlin曲线和动态力学性能测试显示RGE复合材料的Payne效应最强,RCB复合材料的Payne效应最弱。

| Abstract: | The Payne effect is manifest as a dependence of the viscoelastic storage modulus on the amplitude of applied strain.The Payne effect of filled rubber is studied in order to ensure the safety and reliability of rubber products with good mechanical properties.Carbon black/natural rubber (RCB) composites,carbon nanotubes/NR (RCNT) composites and graphene/NR (RGE) composites were prepared by latex mixing-twin roll process.According to SEM and TEM images,the filler is uniformly dispersed in the rubber matrix.Mooney-Rivlin curve and Dynamical mechanical analysis reveal that among the three composites,the Payne effect of RGE composites is the strongest while RCB composite is the weakest. |
