采用熔融共混法制备出了高抗冲聚苯乙烯(HIPS)/高性能纳米氢氧化铝(nano-CG-ATH)/包覆红磷(ERP)/改性聚苯醚(MPPO)无卤阻燃复合材料,研究了nano-CG-ATH、ERP和MPPO对HIPS基复合材料阻燃性能、力学性能和热稳定性的影响;利用扫描电镜分析了HIPS基复合材料燃烧后的炭层形貌;利用傅里叶变换红外光谱分析了HIPS/nano-CG-ATH/ERP/MPPO(60/6/9/25)复合材料及其经不同温度热处理后残留物的结构.结果表明,nano-CG-ATH、ERP和MPPO之间有很好的协效阻燃效果,当nano-CG-ATH用量为6％(质量分数,下同),ERP用量为9％,MPPO用量为25％时,HIPS复合材料的极限氧指数达到27.5％,UL-94级别达到Ⅴ-0级;该复合材料的拉伸强度达到30.04 MPa,弯曲模量达到2485.60 MPa;热分解后残留物质的量达到10.58％.但是该复合材料的冲击性能有待提高.
