摘要： 采用空心玻璃微珠（HGM）与1乙酸乙酯基3甲基咪唑四氟硼酸盐（［EOOEMIm］·［BF4］）离子液体组合阻燃热塑性聚氨酯弹性体（TPU）,并通过锥形量热仪（CCT）、烟密度仪（SDT）和热重红外联用（TGIR）等手段研究了阻燃TPU的燃烧和热降解性能。锥形量热仪实验结果表明，HGM与［EOOEMIm］［BF4］的组合物能够显著提高TPU的阻燃性能。其中0005%（质量分数）［EOOEMIm］［BF4］和0995%(质量分数)HGM组合使TPU的热释放速率峰值（PHRR）降至最低（43144 kW·m-2）（TPU4）， 比纯TPU（1 41737 kW·m-2）与只含空心玻璃微珠的复合材料（53780 kW·m-2）分别降低了6956%和1978%。烟密度实验表明，无焰条件下HGM与［EOOEMIm］［BF4］的组合物能够使得光通量（LF）显著提高。TGIR结果显示， HGM与［EOOEMIm］［BF4］的组合物能够提高TPU的热稳定性，降低有毒气体的生成。

Abstract: In this paper, a series of flame retardant thermoplastic polyurethane (TPU) composites were prepared based on the combination of hollow glass microspheres (HGM) and 1((ethoxycarbonyl)methyl)3methylimidazolium tetrafluoroborate (［EOOEMIm］［BF4］). The combustion behavior and thermal degradation properties of TPU composites were investigated by cone calorimeter test (CCT), smoke density test (SDT), and thermogravimetric analysis/infrared spectrometry (TGIR), respectively. The CCT results showed that the introduction of HGM and ［EOOEMIm］［BF4］ into TPU can significantly improve the flame retardant performance of TPU. The peak value of heat release rate (PHRR) from the composite containing 0.995%（mass content） HGM and 0.005% ［EOOEMIm］［BF4］ was the lowest (431.44 kW·m-2), reduced by 69.56% and 19.78% respectively, compared with pure TPU and the composite only containing HGM. The SDT results indicated that the combination of HGM and ［EOOEMIm］［BF4］ could greatly improve the luminous flux (LF) of flame retardant TPU composites in the test without flame. TGIR data revealed that the combination of HGM and ［EOOEMIm］［BF4］ could improve the thermal stability of TPU and reduce the production of some toxic gases.
