摘　　要：采用聚磷酸铵(APP)、三聚氰胺(MEL)和季戊四醇(PER)构成膨胀型阻燃(IFR)体系,以热塑性聚氨酯(TPU)为黏合剂、铝银浆(AlU)为填料,基于五因素三水平正交试验表设计18组试验方案,配制不同试剂用量的膨胀型阻燃聚氨酯银浆溶液(IFR/TPU/AlU溶液)。将IFR/TPU/AlU溶液涂覆于尼龙织物表面以对其进行阻燃整理。锥形量热测试结果显示,阻燃性能最优的是2^(#)试样,其IFR/TPU/AlU溶液的配比为m(APP)∶m(MEL)∶m(PER)∶m(TPU)∶m(AlU)=8∶8∶2∶16∶20,点燃时间为20 s,热释放速率峰值为92.045 kW/m^(2),总释放热量为4.974 MJ/m^(2)。利用场发射扫描电镜可观察到,经IFR/TPU/AlU溶液涂覆的尼龙织物在燃烧后生成了连续、致密的残炭。Ammonium polyphosphate(APP),melamine(MEL)and pentaerythritol(PER)were used to form a intumescent flame retardant(IFR)system,with thermoplastic polyurethane elastomer(TPU)as binder and aluminum silver paste(AlU)as filler,eighteen groups of test schemes were designed to prepare IFR/TPU/AlU solutions with different reagents dosage based on five factors and three levels orthogonal experimental table.The IFR/TPU/AlU solutions were coated on nylon fabrics for flame retardant finishing.The cone calorimetric test results showed that the sample with the best flame retardant properties was 2^(#),whose IFR/TPU/AlU solution ratio was m(APP)∶m(MEL)∶m(PER)∶m(TPU)∶m(AlU)=8∶8∶2∶16∶20,the ignition time was 20 s,the peak heat release rate was 92.045 kW/m^(2),and the total heat release was 4.974 MJ/m^(2).It was observed by field emission scanning electron microscope that the nylon fabrics coated with IFR/TPU/AlU solution formed continuous and dense carbon residue after combustion.
