摘要
在阻燃型高抗冲聚苯乙烯（ＨＩＰＳ）中，加入一定量的ＳｉＯ２作为填充剂。采用偶联剂对无机填料进行表面处理，改善了ＨＩＰＳ与无机填料的界面结构。用电子显微镜观察了无机填料表面处理前后的形态变化。
This paper presents the effect of coupling agent on the mechanical properties of flameretardant high impact polystyrene(HIPS), Fire retarding HIPS is usually used with a certain amount of SiO2 as the filler. To improve the properties of HIPS/SiO2 composite material, coupling agent was used to reinforce the surface interaction between HIPS and SiO2. It was found that the concentration of coupling agent strongly affected the mechanical properties of HIPS/SiO2. There existed a critical concentration of coupling agent, at which the properties of HIPS/SiO2 composite material was enhanced apparently. Results obtained from electron microscope showed that after using coupling agent to treat the surface of SiO2, the interface microstructure of HIPS/SiO2 was changed, The mechanical properties of the HIPS/SiO2 can be improved by adding the coupling agent to this system.
