| 摘 要： | 将可膨胀石墨(EG)、P-N型膨胀阻燃(剂IFR)与ABS树脂共混,制作复合阻燃材料。用氧指数(OI)、UL 94测试和锥形量热仪(CONE)探讨了EG与IFR复合阻燃ABS的协同效应。通过热失重分析(TG)研究了阻燃ABS体系的热失重行为。结果表明:EG与IFR协同阻燃ABS,OI达到29%,UL 94为V-0级,热释放速率大幅度降低,EG与IFR复合阻燃ABS具有一定的协同效应;在空气气氛下,EG与IFR可以相互促进成炭,且形成的炭层稳定在,850℃也不会分解。

| Abstract: | Flame retarded ABS resin was prepared by synergistic flame-retardant of expandable graphite(EG) and P-N intumescent flame retardant(IFR).The synergistic flame retardancy of flame retarded ABS resin were studied by means of oxygen index(OI),UL-94 vertical burning testing and cone calorimeter testing(CONE).The thermal weight loss behavior of flame retarded ABS resin was studied by TG.The results show that:When EG and IFR were used to flame retardant ABS simultaneously,the OI of flame retardant ABS resin can i... |
