【摘要】 选取含卤多元醇为反应性阻燃单体,甲苯二异氰酸酯为硬段,聚氧化丙烯二醇为软段,二羟甲基丙酸为亲水扩链剂,合成了具有阻燃性能的水性聚氨酯。采取氧指数仪对其进行了测试,同时将合成的产物应用于织物阻燃涂层整理。结果表明,25%(占预聚体质量百分数)含卤多元醇改性的水性聚氨酯氧指数为29.8%,且阻燃效果较好。更多还原

【Abstract】 Select a halogen-containing polyol as reactive flame retardant monomers, using toluene diisocyanate as the hard segment, polyoxypropylene diol as a soft segment, bis (hydroxymethyl) propionic acid synthesis is a hydrophilic chain extender. Synthesied a aqueous polyurethane having a flame-retardant properties. The flameretardancy of the polymers were determined by limiting oxygen index (LOI), and the synthetic product used in flame-retardant fabric coating finishing. The results show that. 25% (mass percentage share of prepolymer) halogen-containing polyol-modified waterborne polyurethane oxygen index of 29.8%, and the application is better.更多还原
