摘　　要：通过研究补强材料白炭黑以及助剂偶联剂对导电橡胶力学性能的影响分析,发现白炭黑和偶联剂的加入均可有效增强导电橡胶的力学性能,且对导电橡胶的导电性影响不大。当白炭黑添加量为15%,偶联剂的添加量为0.7%时,力学性能相对最佳。此外,还研究了导电橡胶的高温环境适应性,发现在高温96 h内,导电橡胶的力学性能以及导电性能可保持相对较佳的状态。In this paper,the effects of the silica reinforcing material and coupling agent on the mechanical properties of con⁃ductive rubbers were investigated.The experiment results indicated that the addition of the silica reinforcing material and coupling agent could enhance the mechanical properties of conductive rubbers effectively,but there was little influence on their conductance.The conductive rubbers obtained optimal mechanical performance at a silica content of 15 wt%and a coupling⁃agent content of 0.7 wt%.In addition,the adaptability of conductive rubbers in high⁃temperature environments was evaluated.The results indicated that the conductive rubbers kept relatively stable mechanical properties and electri⁃cal conductance within 96 hours in high⁃temperature environments.
