| 摘 要： | 以甲基环己基次膦酸(MHP)和Na OH反应,然后与金属化合物成盐得到甲基环己基次膦酸铝/铁复盐(Al Fe(MHP))。采用FTIR、XRF及XRD等技术表征其结构。作为阻燃剂应用于环氧树脂(EP)后,对复合材料的燃烧性能及热稳定性进行初步探讨。结果表明,当阻燃剂添加量(质量分数)为10%时,EP的极限氧指数(LOI)从19.8%提高到28.4%,垂直燃烧测试达到UL94 V-0级别。热重分析显示Al Fe(MHP)的热稳定性良好,燃烧性能测试证实Al Fe(MHP)对复合材料的热释放速率(HRR)抑制作用明显。

| Abstract: | Aluminum Iron methyl cyclohexylphosphinate double salt（AlFe（MHP））was synthe？sized initially by neutralization reaction of methyl cyclohexylphosphinate acid with NaOH,followed by reacting with metal compounds. The product was characterized by FTIR,XRF and XRD to anal？yse its structure. When AlFe（MHP）was used as flame retardant in epoxy resin（EP）,the flammabili？ty and thermal stability of the composite were discussed preliminarily. The results presented that the Limit Oxygen Index（LOI）of EP with 10 wt% filler loading improved from 19. 8% to 28. 4%,and the vertical burning test achieved at UL94 V-0 rating. TG analyses showed that AlFe（MHP）had ex？cellent thermal stability. The tests of flammability revealed that AlFe（MHP）had a strong inhibition effect on Heat Release Rate（HRR）of the composites. |
