摘要: 将新型磷系阻燃剂1,3,5-三(5,5-二甲基-1,3-二氧杂环己内磷酸基)苯(FR)、无规聚丙烯(APP)加入聚丙烯(PP)中制备了PP/APP/FR复合材料,采用极限氧指数测定、垂直燃烧实验(UL94)、锥形量热分析对复合材料燃烧性能进行了研究。结果表明,APP/FR提高了犘犘复合材料的氧指数和垂直燃烧性能级别,延长了点燃时间,降低了热释放速率和燃烧烟气中的CO、CO2浓度,阻燃效果显著。当15%(质量分数,下同)FR和10%APP复配阻燃PP时,复合材料的氧指数达29.6%,UL94V-0级。

Abstract: A novel flame rctardant 1,3,5一tri(5,5-dimcthyl-1,3-dioxacyclophosphorinane phosphonatc) benzene(FR) and APP were introduced into polypropylene, and the combustion properties of the com-
positc were studied using limiting oxygen index(LOI),UL94 test, and cone calorimeter test. Itshowed that FR with APP improved the LOI values and UL94 combustion properties, prolonged igni-tion time, and reduced the heat release rate and CO, COZ concentration in smoke. The synergistic effects were prominent. The LOI reached 29.6%and UL94 reached V-0 when 15%FR and 10% APP were added to polypropylene.
