摘要: 以苯胺、苯甲醛、9,10二氢9氧杂10磷杂菲10氧化物(DOPO)为原料合成了一种新型阻燃剂9,10二氢9氧杂10磷杂菲10氧化物4\[(苯胺)甲基\]苯(DOPOFR),并与磷酸三乙酯(TEP)、膨胀石墨(EG)复配制备了阻燃聚氨酯泡沫材料。采用红外光谱分析仪、核磁共振分析仪对DOPOFR的化学结构进行表征,并利用极限氧指数、热重分析仪等对阻燃聚氨酯泡沫材料进行性能分析。结果表明,DOPOFR质量为多元醇的20 %,聚氨酯泡沫材料的极限氧指数就可达24.7 %;DOPOFR的加入提高了聚氨酯泡沫的力学性能和热稳定性;EG、TEP、DOPOFR三者协同阻燃可使聚氨酯泡沫的极限氧指数达到32 %。

Abstract: A novel flame retardant for polyurethane foam, DOPOFR was synthesized by the condensation of benzaldehyde with aniline and DOPO. Using above flame retardant and expandable graphite (EG), triethylphosphate and DOPOFR polyurethane foam was prepared. Chemical structure of DOPOFR was characterized with FTIR, 1HNMR spectra, and 31PNMR spectra. The thermal stability, flameretardant properties, and mechanical behavior of PUFs with different contents of DOPOFR were investigated by thermogravimetric analysis, limited oxygen index, and universal testing machine. It showed that DOPOFR could form more char when it was lighted and get excellent flame retardancy for PUFs. The  limited oxygen index value reached 24.7 % with only 20 wt % of DOPOFR. The synergistic effect among EG, triethylphosphate, and DOPOFR could further increase the limited oxygen index to 32 %.
