摘要： 使用1乙酸乙酯基3甲基咪唑六氟磷酸盐（［EOOEMIm］［PF6］）协效芳纶纤维（AF）阻燃热塑性聚氨酯（TPU），采取锥形量热仪（CCT）、热重分析（TGA）和热重红外联用（TGIR）等手段对阻燃TPU的燃烧性能及热解性能进行了测试研究。研究结果表明［EOOEMIm］［PF6］协效AF阻燃体系可以有效地提高TPU的热稳定性，AF和［EOOEMIm］［PF6］的添加量(质量分数)各为05%时效果最为明显，其中热释放速率峰值（PHRR）降低至2532 kW·m-2，较纯TPU降低了6722%，此外，烟参数也得到了明显改善；TGA结果显示,AF和［EOOEMIm］［PF6］的添加可以提高阻燃TPU的炭渣余量；TGIR结果表明,［EOOEMIm］［PF6］协效AF阻燃体系可以降低TPU热解过程中CO2、H2O及挥发性有机物的释放量。这说明［EOOEMIm］［PF6］协效AF体系具有良好的阻燃效果和应用前景。

Abstract: In this paper, a system of 1ethylacetate3methylimidazolium hexafluorophosphate(［EOOEMIm］［PF6］) synergistic aramid fiber(AF) were used to prepare flame retardant thermoplastic polyurethane, the combustion performance and pyrolysis performance of flameretardant TPU were tested by cone calorimetry(CCT), thermogravimetric analysis(TGA) and thermogravimetric analysis/infrared spectrometry(TGIR). The results of the study showed that the flameretardant system of ［EOOEMIm］［PF6］ synergistic AF could improve the thermal stability of TPU effectively. The effect was most pronounced when 05% of AF and ［EOOEMIm］［PF6］ were added, the peak heat release rate (PHRR) was reduced to 2532 kW·m-2, which was 6722% lower than that of pure TPU, and the smoke parameters also improved significantly. The TGA results showed that the addition of AF and ［EOOEMIm］ ［PF6］ could improve the residual carbon residue of flameretardant TPU. The TGIR results showed that the flameretardant system of ［EOOEMIm］［PF6］ synergistic AF could reduce the release of CO2, H2O and volatile organic compounds during the pyrolysis of TPU. These results proved that the ［EOOEMIm］［PF6］ coefficient AF system has a good flameretardant effect and application prospects.
