| 摘 要： | 用熔融混合法制备了高抗冲聚苯乙烯(HIPS)/微胶囊红磷(MRP)/膨胀石墨(EG)无卤阻燃材料.用氧指数法、垂直燃烧及热重分析等方法研究了EG/MRP复配阻燃剂对高抗冲聚苯乙烯的阻燃作用,并对阻燃前后的HIPS复合阻燃材料进行了红外分析。结果表明,MRP和EG复配,可以使HIPS的氧指数提高到27%,垂直燃烧级别达到FV-0(1.5 mm);但是MRP与EG之间不存在协同阻燃效应;复配阻燃剂的作用机理为凝聚相阻燃机理,抗滴落剂的加入可以有效阻止材料燃烧时的滴落,提高材料的阻燃级别。

| Abstract: | Halogen-free flame retardant materials of high impact polystyrene(HIPS)/micro-capsulated red phosphorus(MRP)/expandable graphite(EG)were prepared via melt blending.The flame retardant effect of EG/MRP composite was studied through oxygen index,vertical burning test,and thermal gravimetric analysis.HIPS before and after flame retardant was characterized by Fourier transform infrared spectroscopy(FTIR).The results showed that compound flame retardant of MRP and EG may increase the oxygen index of HIPS to 27% ... |
