摘要 采用浓硝酸(HNO3)氧化处理后的多壁碳纳米管(MWNTs)与丁苯橡胶(SBR)及其他配合剂在开炼机上进行混炼加工制备MWNTs/橡胶复合材料,并与炭黑补强橡胶体系进行对比,进而研究了MWNTs/橡胶复合材料的物理性能,并初步探讨了该材料微观结构与性能之间的关系.结果表明:随着MWNTs质量百分含量的增加,橡胶复合材料的力学性能也随之增高;MWNTs/橡胶复合材料的抗撕裂强度(25.9kN/m)、硬度(58)、磨耗(0.22mL/1.61km) 性能较炭黑/ 橡胶体系要好.由MWNTs补强的橡胶对开发具有低滚动滞后性和抗疲劳损失的轮胎胎面胶将有很大的实用潜力. Carbon nanotubes (CNTs) have excellent mechanical properties which make them prime candidates for application in high performance composite materials. Modified multi-walled carbon nanotubes (MWNTs) were achieved by refluxing the tubes in a HNO3 (67 %) solution, blending them with SBR rubber and compatibilizers, and then processing in an open-mixer. The effects of different content of MWNTs on the performance and micro-structure of the SBR composites were investigated and compared with that of carbon black (N330) filled composites. Results show that the tensile strength of MWNT/SBR composites increases with increasing the MWNT content. The Shore hardness (58), tear strength (25.9 kN/m), and abrasion (0.22 mL/1.61 km) of the MWNT/SBR composite are better than those of carbon black (N330)/SBR composites, which points to promising applications for tires with low rolling hysteresis and decreased fatigue loss.
