摘　　要：用三聚氰胺、磷酸等对木绣球提取物进行改性,制备木绣球基膨胀型阻燃剂(VMIFR)。用红外(FTIR)和热重(TGA)对产物进行了表征。热分析表明,改性木绣球最大热分解温度为393℃。将制备的阻燃剂用于阻燃环氧树脂,用热重、极限氧指数(LOI)等方法对材料的阻燃性能进行了分析。当磷酸与三聚氰胺的摩尔配比为2∶1时制备的阻燃剂性能最佳。当阻燃剂添加量为30 wt%时,阻燃环氧树脂的氧指数可达到30.9%。The viburnum macrocephalum extracts were modified with melamine and phosphoric acid to prepare Viburnum macrocephalum based intumescent flame retardant(VMIFR).The product was characterized by infrared(FTIR)and thermogravimetric(TGA).Thermal analysis showed that the maximum thermal decomposition temperature of VMIFR was 393℃.The flame retardants were applied to the flame-retarding epoxy resin,and the flame retardancy was analyzed by TG and LOI.The best flame retardant was prepared when the molar ratio of phosphoric acid and melamine was 2∶1.When the flame retardant loading was 30 wt%,the oxygen index of flame-retarding epoxy resin reached 30.9%.
