摘要

本研究的目的是通过加入三种不同的磷基阻燃剂，即次磷酸铝（AHP）、聚磷酸铵（APP）和次磷酸二乙酯铝（AlPi），在5、10和20的浓度下，提高鸡毛（CF）增强热塑性聚氨酯（TPU）复合材料的阻燃性能重量%。通过各种测试评估添加剂的有效性，包括极限氧指数（LOI）、垂直燃烧测试（UL 94V）、热重分析（TGA）和质量损失量热计测试（MLC）。结果表明，这三种添加剂在冷凝相和气相中都表现出阻燃性能，但APP和AHP由于其增强的成焦能力而比AlPi表现得更好。添加剂的阻燃效果依次为APP＞AHP＞AlPi。

The effect of phosphorus based flame retardants on the thermal and fire retardant properties of chicken feather/thermoplastic polyurethane composites

The aim of the study was to enhance the flame-retardant properties of chicken feather (CF) reinforced thermoplastic polyurethane (TPU) composites by incorporating three different phosphorus-based flame retardants, namely aluminum hypophosphite (AHP), ammonium polyphosphate (APP), and aluminum diethyl phosphinate (AlPi), at concentrations of 5, 10, and 20 wt%. The effectiveness of the additives was evaluated through various tests, including limiting oxygen index (LOI), vertical burning test (UL 94 V), thermogravimetric analysis (TGA), and mass loss calorimeter test (MLC). The results indicated that all three additives exhibited flame retardant properties in both the condensed and gas phases, but APP and AHP performed better than AlPi due to their enhanced char formation capabilities. The flame retardant effectiveness of the additives decreased in the order of APP > AHP > AlPi.
