磷氮多元醇及其功能化石墨烯阻燃环氧树脂研究

Study on Phosphorus-Nitrogen Polyols and Their Functionalized Graphene Flame Retardant Epoxy Resin

针对当前材料应用方面环氧树脂阻燃性的要求,结合当前的相关试验材料,以双酚A型环氧树脂作为改性对象,在该环氧树脂中加入氮磷多元醇功能化石墨烯,从而对上述的环氧树脂进行改性。最后通过玻璃化转变温度等测试方法,验证了上述制备的环氧树脂具有良好的阻燃性能,说明该改性方法具有可行性。

In view of the requirements of flame retardancy of epoxy resin in current material application,combined with the current related experimental materials,bisphenol A epoxy resin was modified by adding functional graphene of nitrogen and phosphorus polyols into the epoxy resin.Finally,the flame retardant properties of the modified epoxy resin were verified by the glass transition temperature and other test methods,which indicated that the modification method was feasible.
