摘要： 以新戊二醇、三氯氧磷、1，2，3-三羟基苯为原料合成新型磷系阻燃剂1，2，3－三(5，5－二甲基－1，3－二氧杂己内磷酰氧基)苯(FR)，将FR与环氧树脂(EP)熔融混合制备阻燃EP/FR复合材料。采用极限氧指数测试、垂直燃烧实验、热重分析、锥形量热分析、扫描电镜研究了FR对EP的阻燃性能和阻燃机理。结果表明，添加20 % FR的EP/FR复合材料的极限氧指数达到27.8 %，垂直燃烧通过UL94 V-0级，热释放速率平均值和生烟量平均值比未阻燃EP分别降低了77.0 %和82.8 %，扫描电镜分析表明， EP/FR体系燃烧后能形成连续、致密、封闭的焦化炭层。

Abstract: A novel phosphorus fire retardant, 1,2,3-tri(5,5-dimethyl-1,3, -dioxaphosphorinanyl-2-oxy)benzene (FR), was synthesized from 1,2,3-tri(hydroxy)benzene, neopentyl glycol, and phosphorus oxychloride, and was employed in epoxy resin system. The flame retarding effect on limited oxygen index (LOI) and UL-94 was studied. It showed that FR was effective on the flame retardancy of epoxy resin at a content of 20 %, UL94 V-0 rating and an LOI of 27.8 % were reached. The cone experiment showed that the av-HRR and av-SEA of the FR-containing epoxy resin were 77.0 % and 82.8 % lower than neat resin, respectively. SEM observation revealed that a continuous, dense, strong, and closed charred layer was formed.
