摘　　要：测试了三种铝粉的粒度、形貌、比表面积和有效铝含量。选取二茂铁、硼粉、高氯酸铵、氟橡胶F_(246)、Fe_(2)O_(3)、全氟表面活性剂HX-12六种助燃剂,通过高温DSC研究了助燃剂对铝粉的助燃效果。结果显示,硼粉助燃效果最好,硼粉的加入使铝粉增加了两个放热峰。当硼粉含量为10%时,总放热量为纯铝粉FLQT-4的2倍以上。Particle size,morphology,specific surface area and effective aluminum content of three kinds of aluminum powders were tested.The combustion improver of ferrocene,boron powder,ammonium perchlorate,fluororubber F_(246),Fe_(2)O_(3),and perfluoro surfactant HX-12 were selected to investigate the combustion-supporting effect of combustion improver on aluminum powder at high temperature by DSC.The results show that boron powder has the best combustion-supporting effect.The addition of boron powder increases two exothermic peaks of aluminum powder.When the content of boron powder is 10%,the total heat release is more than 2 times than that of pure aluminum powder FLQT-4.

关 键 词：硼粉 铝粉 助燃 总放热量
