摘　　要：用乙烯基硅烷偶联剂(A-172)对膨胀阻燃剂(IFR)进行表面改性,研究了该阻燃剂对聚丙烯(PP)体系力学性能和阻燃性能的影响。结果表明:当A-172/IFR/PP为0.5/22.5/77.5时,体系的力学性能基本不变,但阻燃性能得到了改善。其中氧指数同比提高了22.5%,体系的热释放速率峰值和烟释放速率峰值同比分别下降了9.7%和98.75%。Intumescent flame retardant（IFR） was modified by vinyl silane coupling agent（A-172）.The effect of A-172 on mechanical property and flame retardancy of PP composite was investigated.The results show that when A-172/IFR/PP=0.5/22.5/77.5,there is little change for the mechanical property of the composite,but the flame retardancy of the composite is improved,wherein the OI increases by 22.5%,and the peak values of heat release rate and smoke production rate decrease by 9.7% and 98.75% respectively.
