摘要

摘要: 通过球磨分散法和熔融共混法制得纳米Sb₂O₃/溴化环氧树脂-聚丙烯（BEO-PP）阻燃复合材料试样。采用XRD、DSC、拉伸和冲击性能测试，研究了纳米Sb₂O₃/BEO-PP阻燃复合材料的力学性能及其增强机制。研究结果表明：采用球磨法改性后的纳米Sb₂O₃颗粒在PP基体中的分散性和黏结性能得到明显改善；纳米Sb₂O₃颗粒的加入可改善PP基复合材料的强韧性；随着纳米Sb₂O₃质量分数的升高，纳米Sb₂O₃/BEO-PP复合材料的力学性能呈现出先升后降的趋势，PP基体的结晶度逐渐增高；当纳米Sb₂O₃颗粒添加量为2wt%时，纳米Sb₂O₃/BEO-PP复合材料表现出优异的综合性能。

Abstract: The nano Sb₂O₃/brominated epoxy resin-polypropylene (BEO-PP) flame retardance composite and the testing splines were obtained by ball milling dispersion and melt-mixing method, respectively. The mechanical properties and reinforced mechanism of the nano Sb₂O₃/BEO-PP composite were studied by XRD, DSC and tensile and impact test. The results show that the dispersion and the cohesive properties of nano Sb₂O₃ in the matrix are improved obviously by ball milling modification method; Meanwhile, nano Sb₂O₃ particles can enhance the toughness and strength of nano Sb₂O₃/BEO-PP composites. Besides, with increasing of the mass fraction of nano Sb₂O₃, the strength of the composites increases firstly and then decreases and the crystallinity of PP matrix also increases gradually. Nano Sb₂O₃/BEO-PP composites with 2wt% of the mass fraction of nano Sb₂O₃ possesses superior comprehensive performance.
