| 摘 要： | 研究了钛酸酯偶联剂（TTOPP）对聚丙烯/膨胀型阻燃剂（PP/IFR）复合材料阻燃性能和力学性能的影响，并采用扫描电子显微镜、偏光显微镜和X射线衍射研究了复合材料的微观形态和结晶行为。结果表明，加入TTOPP后，IFR在PP中的分散更加均匀，PP球晶的大小趋于一致，适量的TTOPP改善了IFR与PP间的相容性，促进了IFR对PP形成β晶的诱导作用。当PP/IFR/TTOPP为75/25/0.375时，复合材料的综合性能最佳，自熄时间降到24 s，拉伸强度和冲击强度比PP/IFR分别提高了14.0 %和12.0 %。

| Abstract: | Effect of titanate coupling agent on mechanical properties and flame retardancy of polypropylene/intumescent flame retardant (PP/IFR) composites was studied. Micromorphology and crystallization behavior of the composites were analyzed by scanning electron microscope, polarization microscope and X-ray diffraction. It showed that dispersion of IFR and spherulite size of PP became uniform, and TTOPP could promote the formation of β-form crystal. The adhesions between PP and IFR was enhanced by TTOPP. PP/IFR/TTOPP(75/25/0.375) composite had the optimal properties, and its impact strength and tensile strength were improved by 14.0 ％ and 12.0 ％ than that of PP/IFR, respectively, and its extinguish time decreased to 24 s. |
