Abstract: 以次磷酸、原甲酸三甲酯、丙烯腈等为原料合成了一种新的尼龙66阻燃剂双(2-羧基乙基)膦酸.应用傅里叶变换红外光谱仪(FTIR)、X射线能谱分析(EDS)、差示扫描量热分析(DSC)和热重分析仪(TGA)分别表征双(2-羧基乙基)膦酸的化学结构、元素组成和热稳定性,并将双(2-羧基乙基)膦酸加入到尼龙66的反应体系中,制备了阻燃尼龙66.研究结果表明:通过控制反应温度、反应时间和反应物摩尔比,双(2-羧基乙基)膦酸产率可达到50.79%;合成的阻燃剂具有双(2-羧基乙基)膦酸的分子结构特征;双(2-羧基乙基)膦酸的起始分解温度200℃,低于尼龙66聚合反应温度,但作为预聚体添加到尼龙66中,满足尼龙66合成工艺;在800℃时残炭量为6.36%,说明双(2-羧基乙基)膦酸具有较好的成炭性;当双(2-羧基乙基)膦酸添加量为6%时,阻燃尼龙66的LOI值达到28.0%;当双(2-羧基乙基)膦酸添加量达4%或更高时,垂直燃烧性能达到V-0级别.
