In this study, hydrogen-storage glass microballoons were introduced into emulsion explosives to improve the detonation performance of the explosives. The effect of hydrogen-storage pressure on the detonation characteristics of emulsion explosives was systematically investigated. Detonation velocity experiments shows that the change of sensitizing gas and the increase of hydrogen pressure have different effects on the detonation velocity. The experimental parameters of underwater explosion increase first and then decreases with the increase of hydrogen pressure. The decrease of these parameters indicates that the strength of glass microballoons is the limiting factor to improve the detonation performance of hydrogen-storage emulsion explosives. Compared with the traditional emulsion explosives, the maximum peak pressure of shock wave of hydrogen-storage emulsion explosives increases by 10.6% at 1.0 m and 10.2% at 1.2 m, the maximum values of shock impulse increase by 5.7% at 1.0 m and 19.4% at 1.2 m. The stored hydrogen has dual effects of sensitizers and energetic additives, which can improve the energy output of emulsion explosives.

本研究将储氢玻璃微球引入乳化炸药中，以提高炸药的爆轰性能。系统研究了储氢压力对乳化炸药起爆特性的影响。爆速实验表明，敏化气体的变化和氢气压力的增加对爆速的影响不同。水下爆炸实验参数随着氢气压力的增大先增大后减小。这些参数的降低表明玻璃微球的强度是提高储氢乳化炸药爆轰性能的限制因素。与传统乳化炸药相比，储氢乳化炸药冲击波最大峰值压力在1.0 m处增加10.6%，在1.2 m处增加10.2%，冲击脉冲最大值在1.0 m处增加5.7%，在1.2 m处增加19.4%。储存的氢气具有敏化剂和高能添加剂的双重作用，可以提高乳化炸药的能量输出。
