摘　　要：针对井下高温高压密封用橡胶材料的性能需求,主要研究了不同碳纳米管/炭黑质量比对于四丙氟橡胶常温、高温力学性能的影响规律,并对不同配方复合材料的快速气体减压性能进行了测试。结果表明,在标准工艺条件下,采用适当碳纳米管/炭黑质量比增强四丙氟橡胶的常温、高温力学性能较原配方有着明显提升,而增强体质量比、工艺条件则会导致材料产生不同的团聚特性并形成微观缺陷,从而影响材料的强度与快速气体减压性能。In view of the performance requirements of rubber materials for underground high temperature and high pressure sealing field,the properties of tetrafluoropropylene rubber(FEPM)at room temperature,high temperature and gas explosion resistance based on carbon nanotubes(CNTs)/carbon black reinforced system were studied.In this paper,the effects of different carbon nanotube/carbon black ratio on the mechanical properties of tetrafluoropropylene rubber at room temperature and high temperature were studied,and the rapid gas decompression properties of composites with different formulations were tested.The results showed that under the standard process conditions,the mechanical properties at room temperature and high temperature of tetrafluoropropylene rubber reinforced with appropriate carbon nanotube/carbon black components were significantly improved compared with the original formulation,while the ratio of reinforcement and process conditions would lead to different agglomeration characteristics and micro defects of the materials,thereby affecting the strength and rapid gas decompression performance of the materials.
