摘要
采用聚磷酸密胺(MPP)/季戊四醇(PER)/磷(P)三元膨胀型阻燃剂(IFR)阻燃PP。测定了阻燃PP的极限氧指数(LOI)、UL94V阻燃性及热稳定性,以傅立叶变换红外光谱(FTIR)表征了阻燃PP热分解残余物的特征,以锥形量热仪(CONE)测定了阻燃PP诸多与火灾有关的阻燃参数,包括释热速度、质量损失速度、整释热量、有效燃烧热、比消光面积及点燃时间等,还以扫描电镜(SEM)观测了阻燃PP燃烧残炭的形态。
PP was flame-retarded with melamine polyphosphate （MPP）/pentaerythritol（PER）/ phosphorus （P） Tertiary intumescent flame retardants （IFR）, The limiting oxygen index, UL94V flame retardancy and thermal stability of the flame-retarded PP were measured. The FTIR technique was used to analyze the pyrolysis residue and the cone calorimeter（CONE） was applied to determine a number of combustion parameters which were closely related to fire safety,including heat release rate, mass loss rate,effective combustion heat,total heat release,specific extinction area and the time of ignition. In addition,the morphology of the residue from CONE measurement was observed by scanning electron microscope（SEM）.
