　　将硼酸锌（ZB）添加膨胀阻燃聚丙烯体系(PP/IFR)中，利用热重分析仪（TGA）、 X-射线荧光光谱仪（EDX）和红外光谱仪（FTIR）分析了该膨胀阻燃体系的热降解动力学和残炭的化学结构。结果表明，添加ZB后， PP/IFR体系提前分解，但保留了更多的残炭； EDX和FTIR分析结果表明，残炭中保留了更多的磷，且少量的ZB能促使IFR发生酯化反应，形成更多P-O-P和P-O-C的交联结构，从而提高材料的阻燃性能。

In this research, zinc boronate (ZB) was incorporated into intumescent flame retardant polypropylene (PP/IFR). Afterward, thermal degradation kinetics and char chemical structure of the new compound were analyzed by thermo gravimetric Analyzer (TGA), X-ray Fluorescence Spectrometer (EDX) and Fourier Transform infrared spectroscopy (FTIR). The findings of the research indicated that incorporation of ZB into PP/IFR accelerated the degradation of the system and generated more char residue; EDX and FTIR analysis indicated greater amount of phosphorous residue in chars, and ZB could catalyze esterification reaction of IFR to form more P-O-P and P-O-C network structure, thereby improving the flame retardant performance of materials.
