| 摘 要： | 将氧化亚镍(NiO)与膨胀阻燃剂(RTB-IFR,未添加协效剂成分)复配,应用在聚丙烯(PP)复合材料中以研究NiO的阻燃协效作用。探讨了NiO对膨胀阻燃PP复合材料的阻燃性能、力学性能及热降解行为的影响。结果表明,在PP中单独添加20%RTB-IFR阻燃剂,PP复合材料具有较好的阻燃性能,氧指数为31.8%,3.2 mm样条能通过UL94 V-0级。当RTB-IFR阻燃剂中加入5%NiO时,PP复合材料的阻燃性能明显得到提高,氧指数达到33.6%,1.6 mm样条即能通过UL94 V-0级。同时,NiO对PP复合材料的力学性能影响较小。NiO的引入改变了RTB-IFR及RTB-IFR/PP体系的热降解过程,降低了PP复合材料的热分解速率,提高了复合材料高温时的残炭量和热稳定性。

| Abstract: | In this paper,NiO was used as an effective synergist for RTB-IFR intumescent flame retardant that was produced(RTB-IFR was trademark).The synergistic flame retardant effects of NiO in application in PP composite was studied.The flame retardance,mechanical properties and thermal degradation behavior of NiO on PP system were investigated.Results showed adding 20%RTB-IFR,the 3.2 mm RTB-IFR/PP sample can pass UL94 V-0 rating with LOI of 31.8%and had well flame retardance.By addition of 5%NiO,the 1.6 mm sample c... |
