摘要： 为提高芳纶织物的抗穿刺性能，以自制慢速反应的本征阻燃聚脲为基体对其进行涂敷整理。通过傅里叶变换红外光谱仪、核磁共振波谱仪表征了潜伏固化剂及阻燃聚脲化学结构；采用热重分析、垂直燃烧、极限氧指数、偏光显微镜、隐形车衣穿刺测试仪及万能材料试验机，研究了复合织物热稳定性、阻燃性能、微观形貌及抗穿刺性能。结果表明，聚脲/芳纶复合织物表现出易燃性，但随着本征阻燃聚脲基体中含磷多元醇比例增加，芳纶复合织物阻燃性能逐步提高，当含磷多元醇比例达到21%时，聚脲/芳纶复合织物在垂直燃烧测试中自熄，炭长仅为2.1 cm，极限氧指数达到了28.5%，达到了难燃织物的级别。同时，聚脲涂层显著提升了芳纶织物的抗穿刺性能。

Abstract: To enhance the puncture resistance of aramid fabric, a self-synthesized polyurethane with intrinsic flame-retardant properties and a slow reaction rate was used as the coating matrix in the finishing treatment. The polyurea/aramid composite fabric was prepared using a coating method. The chemical structures of the latent curing agent and flame-retardant polyurea were characterized by Fourier Transform Infrared Spectroscopy and Nuclear Magnetic Resonance spectroscopy. The thermal stability, flame-retardant properties, microstructure, and puncture resistance of the composite fabric were analyzed using thermogravimetric analysis, vertical burning tests, limiting oxygen index tests, polarizing microscopy, puncture testing instruments, and a universal testing machine. The results indicated that while the aramid/polyurea fabric was initially flammable, its flame-retardant performance improved with an increasing proportion of phosphorus-containing polyols in the polyurea matrix. When the proportion of phosphorus-containing polyols reached 21%, the polyurea/aramid composite fabric self-extinguished in the vertical burning test, with a char length of only 2.1 cm and a limiting oxygen index of 28.5%, qualifying it as a flame-retardant fabric. Moreover, the polyurea coating significantly enhanced the puncture resistance of the aramid fabric.
