摘　　要：采用机械共混法制备铜粉/海泡石/氟橡胶复合材料,考察多尺度填料不同用量下复合材料硫化性能、力学性能、老化性能及热性能,并采用扫描电镜观察氟橡胶复合材料拉伸断面形貌。结果表明:纤维状海泡石和铜粉均能提高氟橡胶混炼胶的硫化速率;而两种填料的添加使得复合材料拉伸强度降低,且易加速氟橡胶的老化;与添加单独填料相比,纤维状海泡石和铜粉协同改性能够提高氟橡胶复合材料的邵尔硬度和耐热性能。The copper powder/fibrous sepiolite/fluororubber composites were prepared by mechanical mixing,and the cure characteristics,mechanical properties,aging performances and thermal properties of composites were investigated by adjusting the content of fibrous sepiolite and copper powder.The dispersion of fillers in fluororubber was characterized by scanning electron microscope.The results showed that fibrous sepiolite and copper powder can both improve the cure velocity of fluororubber,the tensile strength of composites was decreased.The fibrous sepiolite and copper powder can accelerate aging of fluororubber.Compared with single filler,the heat resistance and Shore A hardness of composites were improved by the synergistic effect of copper powder and fibrous sepiolite.
