摘要: 将磷系阻燃剂1,3,5-三(5,5-二甲基-1,3-二氧杂环己内磷酸基)苯(FR)、聚磷酸铵(APP)、纳米SiO2复配,制备聚丙烯(PP)纳米复合阻燃材料。采用氧指数测定仪、水平垂直燃烧测定仪、热重分析仪、锥形量热仪对PP纳米复合阻燃材料的阻燃性能进行了研究。结果表明,FR/APP/SiO2提高了PP的氧指数、水平燃烧等级、热稳定性和残炭率,降低了热释放速率。当阻燃剂FR/APP/SiO2的总体含量为25 %,FR/APP/SiO2配比为15/7/3的情况下,PP纳米复合阻燃材料的氧指数为29.4 %,水平燃烧等级为FH-1。

Abstract: An intumescent flame-retardant was prepared by compounding 1,3,5-tri(5,5-dimethyl-1,3-dioxacyclophosphorinane phosphonate) benzene (FR), ammonium polyphosphate (APP), and nano-silica, and used in polypropylene(PP). Testing through limiting oxygen index, horizontal burning test, thermo gravimetric analysis (TG), and cone calorimeter showed that the compound flame-retardant increased the limiting oxygen index, horizontal burning rate, thermal stability, and residual char, and decreased the heat release rate. When the weight ratios of FR/APP/SiO2 were 15/7/3 and its content was 25 %, limiting oxygen index of 29.4 % and horizontal burning rate of FH-1 were obtained.
