摘要: 以双三羟甲基丙烷为原料合成一种新型含磷阻燃剂,该阻燃剂分子量较大,具有稳定的环状结构,热稳定性高于常用阻燃剂,阻燃效果好。探讨了原料配比、反应温度、反应时间对产率的影响,考察了目标产物的热稳定性能及其对不同织物的阻燃效果,用傅里叶变换红外光谱仪表征了中间体及目标产物的结构。结果表明,当原料配比为1∶3时,磷化温度为50℃,磷化时间5h,胺化温度为75℃时,反应效果较好,收率可达90%以上。目标产物对于锦纶的阻燃效果比较明显,对涤纶、棉有一定的阻燃效果,对于混纺、腈纶阻燃效果不明显。

Abstract: A novel phosphorous-containing flame retardant was synthesized with double trimethylolpropane as raw material. The flame retardancy of the flame retardant is good due to its high molecular weight,stable loop structure,and higher thermal stability compared with common flame retardants. The effects of raw material ratio,reaction temperature and reaction time on the yield were discussed. The thermal stability of target product and its flame retardancy to different fabrics were investigated. The structures of intermediates and target product were characterized with Fourier transform infrared spectrometer. The results show that reaction effect was better when raw material ratio was 1∶3,phosphating temperature was 50℃,reaction time was 5h,and amination temperature was 75℃. And the flame retardant has obvious flame retardancy to nylon,has certain flame retardant effect to polyester and cotton,but no obvious retardancy to blending and acrylic

Key words: double trimethylolpropane, ethanolamine, flame retardant, performance
