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.
