Industrial explosives with a low detonation velocity serve as the core-driven energy source for explosive cladding, but have a limited pressure output. A composite energetic system containing high-energy explosives/emulsion explosives can overcome this limitation. Accordingly, the search for high-energy explosives with intrinsic safety features is key to achieving such systems. Therefore, in this study, 2,6-diamino-3,5-dinitropyridine-1-oxide (ANPyO) with high-energy-insensitivity characteristics was selected as the energetic agent to prepare a composite energetic system with an ANPyO/emulsion explosive, and its safety and energy release effects were systematically studied. The experimental results showed that the content of ANPyO had a “linear” relationship with the apparent density of the developed composite energetic system, and had little effect on its impact and friction safety (the explosion probability was less than 10 %). In addition, the introduction of ANPyO did not have a significant impact on the detonation velocity of the composite energetic system, with an average detonation velocity of 2650 m ⋅ s−1. However, it did effectively improve the pressure output of the composite system. The peak pressure increased by 23.69 % from 27.27 kPa to 33.73 kPa, while the boosting rate increased by 88.09 % from 1256.68 kPa ⋅ s−1 to 2363.70 kPa ⋅ s−1. The improvement in the pressure output endowed the ANPyO/emulsion explosive composite energetic system with excellent work capacity, enabling T2/Q235 to compound well during explosive cladding. The above studies prove that this system can effectively maintain the relationship between the safety and energy output, positively contributing toward the development of explosive cladding technology.

ANPyO/乳化炸药复合增能系统的制备及性能
具有低爆速的工业炸药用作炸药包壳的核心驱动能源，但压力输出有限。含有高能炸药/乳化炸药的复合高能系统可以克服这一限制。因此，寻找具有本质安全特性的高能炸药是实现此类系统的关键。因此，本研究选择具有高能量不敏感特性的2,6-二氨基-3,5-二硝基吡啶-1-氧化物（ANPyO）作为含能剂，制备了含ANPyO/乳化炸药的复合含能体系，并对其安全性和能量释放效果进行了系统研究。实验结果表明，ANPyO的含量与开发的复合高能系统的表观密度呈“线性”关系，且对其冲击和摩擦安全影响不大（爆炸概率小于10%）。此外，ANPyO的引入对复合高能系统的爆速没有明显影响，平均爆速为2650 m·s-1。但是，它确实有效地提高了复合系统的压力输出。峰值压力从 27.27 kPa 增加到 33.73 kPa，增加了 23.69 %，而增压率从 1256.68 kPa·s -1增加到 2363.70 kPa·s -1 ，增加了 88.09 % 。压力输出的提高赋予了ANPyO/乳液炸药复合能量系统优异的做功能力，使T2/Q235在炸药包壳过程中能够很好地复合。上述研究证明，该系统能够有效地保持安全性和能量输出之间的关系，为爆炸包壳技术的发展做出积极贡献。
