摘要
选用钛酸酯偶联剂对纳米氢氧化铝(nano-ATH)进行表面改性,以改善其在丙烯腈-丁二烯-苯乙烯共聚物(ABS)中的分散性。利用透射电镜(TEM)表征了nano-ATH的改性效果,研究了改性条件对nano-ATH/ABS复合材料性能的影响。结果表明:在偶联剂用量2.5%,改性时间25min,改性温度80℃的条件下,nano-ATH/ABS复合材料的综合性能较好,改性后nano-ATH的分散性得到改善。
Nano-ATH was modified by titanate coupling agent in order to improve its dispersion in ABS. The modified effect of nano-ATH was analyzed by TEM, and the effects of modification conditions on the properties of nano-ATH/ABS composite were studied. The results showed that the comprehensive properties of nano-ATH/ABS composite were optimum when nano-ATH was modified by 2.5% coupling agent for 25min at 80℃. The dispersion of modified nano-ATH was better than that of unmodified nano-ATH.
