摘要

为了提高聚对苯二甲酸丁二醇酯（PBT）的阻燃性能，研究了含有三氧化二锑纳米颗粒（纳米Sb2O3）和溴化聚苯乙烯（BPS）的PBT基阻燃复合材料。采用球磨法将纳米Sb2O3、BPS和PBT分散得到复合粉末，并采用熔融共混和注射成型的方法制备了纳米Sb2O3/BPS-PBT样品。研究了纳米Sb2O3/BPS-PBT复合材料的阻燃性能。结果表明，纳米Sbs2O3能明显提高PBT基复合材料的阻燃性能。当纳米Sb2O3/BPS-PBT复合材料含有质量分数为5%的纳米Sb2O3和质量分数为10%的BPS时，纳米Sb2O3/BPS-PBT复合材料具有优异的阻燃性，其中UL94阻燃度达到V-0级，极限氧指数为28.3%。

Study on the flame retardancy of nano-Sb2O3/BPS-PBT composites

To improve the flame retardancy of polybutylene terephthalate (PBT), PBT-based flame retardant composites containing antimony trioxide nanoparticles (nano-Sb2O3) and brominated polystyrene (BPS) were investigated. Nano-Sb2O3, BPS, and PBT were dispersed by ball milling method to obtain composite powders, and the nano-Sb2O3/BPS-PBT samples were prepared by melt blending and injection molding methods. The flame retardancy of nano-Sb2O3/BPS-PBT composites was investigated. The results showed that nano-Sbs2O3 can obviously improve the flame retardancy of PBT-based composites. When the nano-Sb2O3/BPS-PBT composite contains nano-Sb2O3 with 5 wt% of mass fraction and BPS with 10 wt% of mass fraction, the nano-Sb2O3/BPS-PBT composite has excellent flame retardancy, in which the UL94 degree of flame retardancy achieves V-0 grade and the limit oxygen index is 28.3%.
