三聚氰胺-环三磷腈阻燃剂的制备及其应用

Preparation and Application of Cyclotriphosphazene Modified with Etherized Hexamethylolmelamine

  • 摘要: 磷腈化合物是一类无卤、对环境友好且具有生物相容性的低毒性阻燃剂,但大部分磷腈衍生物是油溶性的,需要通过熔融共混、辊轧等方式才能制成阻燃纤维、塑料,操作工艺复杂,无法直接用于天然纤维,因此大大限制了其应用范围.该文以六羟甲基三聚氰胺和六氯环三磷腈为原料,通过亲核取代、醚化两步法合成了一种水溶性、醇溶性无卤磷腈阻燃剂.用红外光谱(FTIR)、核磁共振谱(^1H NMR、^13C NMR、^31P NMR)和电喷雾电离质谱(ESI-MS)等进行了结构表征,证明其为无氯、P螺原子链接的目标化合物.将该阻燃剂用

     

    Abstract: The phosphazenebased compounds are halogenfree and environmentallyfriendly. Some of them are biocompatible and can be used as flame resistant materials. However, these compounds often lack watersoluble. Some reports attempted to produce a fireretar
