摘　　要：在四溴醚 [四溴双酚A -双 ( 2 -烯丙基 )醚 ]及八溴醚 [四溴双酚A -双 ( 2 ,3 -二溴丙基 )醚 ]的协同作用下 ,研究了三氧化二锑 (Sb2 O3 )纳米颗粒对聚丙烯阻燃性能的影响。分别使用热重分析法、氧指数法和垂直燃烧法评价了以上阻燃剂的阻燃性能。研究结果表明纳米Sb2 O3 颗粒的加入 ,较好地提高了聚丙烯的阻燃性能 ,相对于普通Sb2 O3 颗粒 ,其初始分解温度最大提高 2 7.9℃ ,氧指数增加 1.8% ;阻燃级别由V 1上升至V 0。通过热重分析法与垂直燃烧法、氧指数法对塑料阻燃性能的一致评价 。The flame retardant effect of nano Sb 2O 3 particles in polypropylene (PP), which contained also tetrabromobisphenol-A-bisallylether (tetrabromoether) and tetrabromobisphenol-A-bis-2,3-dibro-mopropylether (octabromoether), was studied using thermal analysis (TGA), oxygen index (OI) and UL-94 standard. Compared with samples using regular Sb 2O 3, the initial decomposion temperature was increased by 27.9 ℃; the value of OI increased by 1.8 %, and the flame-retardant level improved from V-1 to V-0. It also indicated that the results of TGA had a good consistence with OI and UL-94 standard, thus constituted a convenient method to evaluate the flame-retardant properties.
