摘要:: 为了研究超细颗粒5,7-二氨基-4,6-二硝基苯并氧化呋咱（DADNBF）的性质，采用溶剂-非溶剂法制备了超细DADNBF颗粒。研究了超细DADNBF的粒径分布、撞击感度、热稳定性、真空安定性、冲击波感度和飞片起爆感度等性能，并与普通DADNBF和超细HNS-Ⅳ进行比较。研究结果表明：DADNBF超细化后，样品粒度主要分布在0.035~0.316 μm范围内；比表面积为25.1 m²/g；撞击感度H₅₀为108 cm； DSC分解放热峰温为300 ℃，比细化前降低13 ℃；飞片起爆实验最低起爆电压为2.4 kV；冲击波感度X₅₀=7.54 mm。超细DADNBF综合性能与超细HNS-Ⅳ接近。

Abstract:: In order to study the properties of ultrafine 5,7-diamino-4,6-dinitrobenzenfuroxan (DADNBF), ultrafine DADNBF was prepared using solvent/non solvent method. The particle size distribution, impact sensitivity, thermal stability, vacuum stability, shock sensitivity and flyer sensitivity of ultrafine DADNBF were comparatively analyzed with raw DADNBF and ultrafine HNS-Ⅳ. The results show that the particle size distribution of ultrafine DADNBF is in a range of 0.035～0.316 μm, the specific surface area is 25.1 m²/g, and the impact sensitivity (H50) is 108 cm. The temperature at the exothermic peak of ultrafine DADNBF is 300 ℃, 13 ℃ lower than that of the raw DADNBF. The critical initiation voltage of ultrafine DADNBF in flyer initiation test is 2.4 kV and the shock sensitivity(X50) is 7.54 mm. The comprehensive properties of ultrafine DADNBF are similar to ultrafine HNS-Ⅳ.
