摘　　要：选用钛酸酯偶联剂对高性能纳米氢氧化铝(ATH)进行表面改性,以改善其在高抗冲聚苯乙烯(HIPS)中的分散性。利用透射电镜(TEM)和傅立叶红外光谱仪(FTIR)表征了高性能纳米氢氧化铝的改性效果,研究了改性条件对高性能纳米氢氧化铝/高抗冲聚苯乙烯复合材料性能的影响。结果表明,在偶联剂质量分数1.5%,改性时间20 min,改性温度85℃的条件下,高性能纳米氢氧化铝/高抗冲聚苯乙烯复合材料的综合性能较好。改性后高性能纳米氢氧化铝的分散性得以有效的改善,其表面确实包覆了偶联剂分子。High performance nano-aluminum trihydroxide （ATH） was modified by titanate coupling agent in order to improve its dispersion in high impact polystyrene （HIPS）. The modified effect of high performance nano-ATH was analyzed by transmission electron microscopy （TEM） and Fourier transform infrared （FFIR）, and the effects of the modification conditions on the high performance nano-ATH/HIPS composite were studied. The results show that the comprehensive properties of high performance nano-ATH/HIPS composite are better when high performance nano-ATH is modified by coupling agent with mass fraction 1.5 % for 20 min at 85 ℃. The dispersion of modified high performance nano-ATH is better than that of unmodified high performance nano-ATH, and the surface of high performance nano-ATH is successfully encapsulated by coupling agent.
