| 摘 要： | 采用聚磷酸铵(APP)与季戊四醇(PER)复合膨胀阻燃剂(IFR)阻燃聚丙烯,研究了不同含硅物质——硅胶(SG)、硅酮(GM)以及硅晶(SW)纤维对IFR阻燃PP性能的影响,并通过LOI、UL-94、TGA对材料阻燃性能进行了表征。结果表明,三种物质与IFR都存在一定的协同效应。然而,硅胶与IFR的协同效应最好,在IFR含量为25%时,添加2%的硅胶,材料氧指数由29提高至35,UL-94也提高至V-0级,材料的高温热稳定性也得到了极大提高,并且能够生成结构更加致密的炭层。

| Abstract: | Polypropylene was flame retarded by intumescent fire retardant of ammonium polyphosphate(APP)and pentaerythritol(PER)compounds,and the synergistic effect of silicon-containing compounds(silicon gel,silicone,silicate whisker)with IFR was studied by using LOI,UL-94 tests and TGA.The results show that all the three silicon-containing compounds show synergistic effect with IFR.However,silicon gel exhibits the optimal synergistic effect due to it can increase the LOI value from 29 to 35,stop the dripping and rai... |
