摘　　要：为探索新型点火药,以满足武器装备更高的需求,以3,5-二硝基苯甲酸根(DNBA)为阴离子,1-烯丙基咪唑(AIM)为配体,过渡金属Mn、Co、Cu为中心离子,合成了3种新型含能配合物燃料,对其晶体结构、热分解特性、燃烧热和机械感度进行了测试;基于此,设计并制备了3种点火药,对其燃烧热、线燃烧速率、输出压力、点火能力和感度进行了测试。结果表明:3种新型含能配合物燃料的热分解温度处于272.93~427.85℃范围,燃烧热处于16.69~18.91 kJ·g^(-1)范围,对机械刺激不敏感;3种点火药的燃烧热处于3.88~4.71 kJ·g^(-1)范围,线燃烧速率处于153.28~187.33 mm·s^(-1)范围,输出压力处于4.36~4.62 MPa范围,撞击感度处于28~32 J,摩擦感度处于216~252 N。In order to explore novel ignition powders to meet the higher demands of weapons and equipment,three new energetic coordination complex fuels were synthesized using 3,5-dinitrobenzoate(DNBA)as the anion,1-allyl imidazole(AIM)as the ligand,and transition metals Mn,Co,and Cu as the central ions.The crystallographic structure,thermal decomposition characteristics,combustion heat,and mechanical sensitivity of these fuels were tested;Based on this,three ignition powders were designed and prepared,and their combustion heat,linear combustion rate,output pressure,ignition ability,and sensitivity were tested.The results show that the thermal decomposition temperature of three novel energetic coordination complex fuels ranges from 272.93℃ to 427.85℃,the combustion heat of which ranges from 16.69 kJ·g^(-1) to 18.91 kJ·g^(-1),and they are insensitive to mechanical stimuli;The combustion heat of the three ignition powders ranges from 3.88 kJ·g^(-1) to 4.71 kJ·g^(-1),the linear combustion rate ranges from 153.28 mm·s^(-1) to 187.33 mm·s^(-1),the output pressure ranges from 4.36 MPa to 4.62 MPa,the impact sensitivity ranges from 28 J to 32 J,and the friction sensitivity ranges from 216 N to 252 N.
