摘要:
使用双引发剂合成新型无卤阻燃剂二乙基次膦酸铝(AlPi). 当反应温度为80 ℃、反应时间为2 h、硫酸铝溶液浓度为0.1 mol/L、pH位于2.0~2.5时,产率为94.4%. 产品结构通过FT-IR、ICP、1H NMR、31P NMR等分析手段表征,热重分析(TG)结果(T1%=391.88 ℃,T5%=429.38 ℃)表明产物热稳定性良好. 当AlPi在尼龙66(PA66)中添加量为15%时,垂直燃烧测试(UL-94)达V-0级,极限氧指数(LOI)达33.2%,阻燃性能明显提高,且冲击强度、弯曲强度等力学性能指数仍保持在材料可使用范围内.
Abstract:
Aluminum diethylphosphinate(AlPi)was synthesized by di-initiator. The optimal reaction conditions were explored,and the yield of AlPi is up to 94.4% under the conditions that the reaction temperature,time,concentration of aluminum sulfate solution and pH are 80 ℃,2 h,0.1 mol/L and 2.0~2.5,respectively. The molecular structure of the sample was characterized by FT-IR,ICP,1H NMR and 31P NMR. The result of thermal stability of the products stated that T1% and T5% are up to 391.88 ℃ and 429.38 ℃ respectively,which could meet decomposition temperature of the excellent flame retardant. The application of AlPi to Nylon 66(PA66)was investigated. When the content is 15%,the LOI to 33.2% and UL94 to V-0,the flame retardant of PA66 has been significantly enhanced. And the bending strength and impact strength still have been remained at reasonable range.
