摘　　要：为使水性聚氨酯织物涂层剂具有耐静水压和阻燃的双重功能,采用聚醚三元醇N330为大分子交联剂,聚醚二元醇(PTMG 2000)、无卤阻燃剂(ExolitOP550)为混合软段,二羟甲基丙酸为亲水性扩连剂,1,4-丁二醇为硬段调节剂,与甲苯二异氰酸酯反应制备了耐静水压阻燃水性聚氨酯(OWPU),并探讨了其在织物涂层中的应用。通过红外(FT-IR)测试方法对其结构进行了表征;通过热失重(TGA)、极限氧指数值(LOI)等测试方法分析了耐静水压阻燃水性聚氨酯的热性能和阻燃性能;通过静水压测试考察了样品织物涂层的耐静水压性能。研究结果表明:无卤阻燃剂的加入使得聚氨酯的阻燃性能提高,残炭量增多,极限氧指数值由21.8%提高到29.0%,耐静水压值在8 k Pa以上,具备了良好的阻燃和耐静水压双重功能。In order to prepare bifunctional waterborne polyurethane fabric coating agent,a series of hydrostatic pressure resistant and flame-retardant waterborne polyurethans（ OWPUS） were synthesized by polyaddition reaction via an acetone process,in which N330 was used as macromolecular crosslinking agent,PTMG 2000 and ExolitOP550 as mixing soft segments,DMPA as hydrophilic chain extender,BDO as hard segment regulator and TDI as hard segment. The structure,thermal property and flameretardancy of prepared OWPUS were characterized by FT-IR,TGA and LOI. In addition,hydrostatic pressure resistant properties were examined by hydrostatic pressure test. The results indicate that the incorporation of ExolitOP550 makes flame-retardant performance become better,with more char residue and an increase of LOI from 21. 8% to 29. 0%. Meanwhile,the hydrostatic pressure of PU still keep above 8 k Pa. Thus,a bifunctional fabric coating agent which has good flame-retardant and hydrostatic pressure resistance has been manufactured.
