摘要(Abstract)：

通过3-氨基苯氧基邻苯二甲腈(3-APN)与9,10-二氢-9-氧杂-10-磷杂菲-10-氧化物(DOPO)反应,合成腈基型含磷阻燃剂DOPO-ATR,将阻燃剂按一定比例与双酚A型E-51环氧树脂复合,制备阻燃环氧固化物。通过TG测试、LOI测试、垂直燃烧测试和锥形量热测试,探究DOPO-ATR对阻燃环氧固化物的热稳定性和阻燃性能的影响,同时探究DOPO-ATR的阻燃机理。结果表明:当DOPO-ATR的添加量为10%时,阻燃环氧树脂的LOI值最大为34.8%,与纯EP相比提升55.4%;UL-94等级为V-0级,热释放速率峰值最小为533.28 kW/m²,与纯EP相比降低32%;总热释放量最小为58.98 MJ/m2,与纯EP相比降低32%;总热释放量最小为58.98 MJ/m²,与纯EP相比降低43%;总烟气释放量最小为35.0 m2,与纯EP相比降低43%;总烟气释放量最小为35.0 m²。同时,DOPO-ATR的加入能够提高EP的热稳定性和残炭率。通过阻燃机理可知,DOPO-ATR在气相和凝聚相中均表现阻燃效果。因此,DOPOATR对EP具有一定的阻燃效果,且阻燃剂含量为10%时,阻燃效果最好。
