摘要: 采用二乙醇胺、自制四溴双酚A环氧树脂(E-21)为原料合成了阻燃聚醚多元醇组分;采用2,4-甲苯二异氰酸酯(TDI)、聚乙二醇(PEG)、三羟甲基丙烷(TMP)为原料,在二月桂酸二丁基锡的作用下,通过逐步聚合反应得到异氰酸酯组分;将两组分按一定比例进行发泡得到阻燃聚氨酯硬质泡沫塑料。利用热重分析仪、水平燃烧测定仪等手段进行了表征,研究了异氰酸酯指数、发泡剂以及阻燃剂对聚氨酯硬质泡沫塑料性能的影响。结果表明,与不添加阻燃剂的聚氨酯硬质泡沫塑料相比,阻燃聚氨酯硬质泡沫塑料的吸热峰温度从294.8 ℃提高到303.8 ℃。

Abstract: A flame-retarded polyehter polyols was synthesized from diethanolamine and homemade tetrabromo-bisphenol-A epoxy resin E-21. An isocyanate was polymerized from these materials step by step which were TDI, PEG-400, and TMP under the effect of dibutyltion dilaurate. Flame retarded rigid polyurethane foams were prepared from these two components, and were characterized by means of TG and horizontal burning tester. The properties of flame retarded rigid polyurethane foams were affected by isocyanate index, blowing agents, and flame retardants. It showed that decalescence temperature was increased from 294.8 ℃ to 303.8 ℃.
