| 摘 要： | 将可膨胀石墨(EG)与P-N型膨胀阻燃剂(IFR)复合阻燃丙烯腈-丁二烯-苯乙烯共聚物(ABS)树脂,阻燃剂添加量为20%(质量分数,下同),通过极限氧指数(LOI)仪、垂直燃烧测试(UL-94)仪、锥形量热(CONE)仪和扫描电镜(SEM)研究了EG与IFR复合阻燃ABS的协同效应。结果表明,EG/IFR质量比为1/1为最佳配比,阻燃ABS的LOI达到29%,UL-94为V-0级;EG与IFR复合阻燃ABS,表现出一定的协同作用;通过SEM观察ABS/EG/IFR试样燃烧后样品发现,EG与IFR起到协同阻燃作用。

| Abstract: | Flame retarded ABS resin was prepared by synergistic flame-retardant of EG and P-N intumescent flame retardant IFR and the total mass ratio of the flame retardant is 20%.The synergistic flame retardancy of flame retarded ABS resin was studied by means of LOI,UL-94 vertical burning testing,CONE and SEM.The results show that the best mass ratio of EG and IFR is 1/1.LOI of retarted ABS is 29%. UL-94 is V-0.When EG and IFR are used to flame retardant ABS at the same time, they have the effect of synergistic fla... |
