为获得更高能量的压装混合炸药，采用含能黏结剂在水悬浮造粒方法下包覆HMX 制备PBX 炸药，对制 备出PBX 炸药的能量与机械感度性能进行研究。结果表明，同等配比情况下，使用含能黏结剂比使用惰性黏结剂制 备的PBX 炸药能量明显提高。与以聚氨酯热塑性弹性体(Estane)制备的LX-14Ⅱ相比，以GAP 基ETPE 制备的JO-13 爆速增加109 m/s、爆热增加226 kJ/kg(提高4.2%)；以BAMO/AMMO 基ETPE 制备的JO-X 爆速增加182 m/s、爆 热增加318 kJ/kg(提高5.9%)，在能量提高的同时，机械感度有所增大。
In order to obtain a higher energy of the pressure packed composite explosive, the PBX explosive was prepared by coating HMX with energetic adhesive in the water suspension granulation method. The energy and mechanical sensitivity properties of the PBX explosive were studied. The results show that the energy of PBX explosive is significantly higher when using energetic binder than inert binder. Compared with LX-14II prepared by polyurethane thermoplastic elastomer (Estane), JO-13 prepared by gap based ETPE increased the detonation speed by 109 m/s and the detonation heat by 226 kJ/kg (increased by 4.2%); JO-X prepared by BAMO/AMMO based ETPE increased the detonation speed by 182 m/s and the detonation heat by 318 kJ/kg (increased by 5.9%), At the same time, the mechanical sensitivity increases with the increase of energy.
