【摘要】 本文通过氧指数、垂直燃烧性能的测试研究了不同阻燃剂、不同MFR的PP及无机填料对PP阻燃性能的影响情况 ,并分析了可能的机理。结果表明 ,PP的阻燃性能不仅受所用阻燃剂的影响外 ,还与体系的熔体流动性能具有很大关系。凡是使熔体流动性能下降的因素都使PP的阻燃性能下降。更多还原

【Abstract】 In this paper the effects of various flame retardants,inorganic fillers and PP resin with different MFR on the fire retardance of the PP were studied by means of testing oxygen index and vertical flammability,and their mechanism was also analyzed.The results showed the fire retardance of PP was affected not only by flame retarding agent used,but also by melt flow ability of the PP system.All these factors which could make the melt flow abillity of the system to decrease had adverse effect on the fire retardance of PP.更多还原
