| 以球磨法制备玄武岩纤维粉末（BFP）并将其用作补强填料，研究BFP用量对BFP/氟橡胶（FEPM）复合材料的硫化特性、物理性能、微观形貌特征、交联密度、高温热稳定性和导热性能的影响。结果表明：BFP粒径分布较宽，粒径在纳米到微米的范围；BFP在FEPM基体中分布均匀，无团聚现象，相容性良好，增韧和增强效果明显；随着BFP用量的增大，BFP/FEPM混炼胶的FL变化不大，Fmax和Fmax－FL增大，t10和t90先延长后缩短，硫化胶的邵尔A型硬度、定伸应力、拉伸强度、交联密度和热导率增大，拉断伸长率呈先增大后减小的趋势，高温热稳定性略有降低。 |

| Basalt fiber powder（BFP） were prepared by ball milling method and was used as reinforcing filler.The effects of BFP dosage on the vulcanization characteristics，physical properties，microscopic morphology characteristics，crosslinking density，high temperature thermal stability and thermal conductivity of BFP/fluororubber（FEPM） composites were studied.The results showed that the particle size distribution of BFP was wide，and the particle size was in the range of nanometer to micron.BFP was uniformly distributed in the FEPM matrix，without agglomeration，with good compatibility，and toughening and reinforcing effects were obvious.With the increase of BFP dosage，the FL of the compound changed little，the Fmax and Fmax－FL increased，thet10 and t90 increased first and then decreased，Shore A hardness，modulus，tensile strength，crosslinking density and thermal conductivity of the vulcanizate increased，the elongation at break increased first and then decreased，and the high temperature thermal stability decreased slightly. |
