摘　　要：本文将一种新型的溴-氮型阻燃1,2-双(四溴邻苯二甲酰亚胺)(BTBPE)乙烷用于高抗冲聚苯乙烯(HIPS)的阻燃改性,同时将其与常用的十溴二苯乙烷(DBDPE)、溴代三嗪(TBPC)阻燃的HIPS进行性能对比,发现其具有更高的热变形温度,但对冲击强度影响较大。将该阻燃剂与溴代三嗪阻燃剂进行复配,得到具有良好综合物理性能的阻燃HIPS材料。通过扫描电镜(SEM)对比两种填充型阻燃剂的形态,说明二者其对于力学性能影响的根本原因;通过热重分析(TG)分析该阻燃剂以更低的溴含量却能达到同样阻燃效果的主要原因。I In this paper,a new bromo-nitrogen type flame retardant 1,2-bis(tetrabromo-phthalimide)(BTBPE)ethane is used to be the flame retardant of high impact polystyrene(HIPS).Compared the performance of HIPS flame retardant by BTBPE,DBDPE and TBPC.By the experiments found that the thermal deformation temperature of BTBPE is higher,but the impact strength is greatly affected.The combination of the flame retardant BTBPE and TBPC gives a good comprehensive physical properties flame retardant HIPS.Use scanning electron microscopy(SEM)to compare the morphology of BTBPE and DBDPE,analysis the influence on mechanical properties.Use Thermogravimetric analysis(TG)to analyze the mechanism of the flame retardant.
