摘要
粘结剂作为PBX炸药中重要的添加剂,对炸药的力学性能、能量特性等都有很大的影响。为研究不同粘结体系对PBX炸药水下爆炸能量特性的影响,首先对不同粘结体系炸药配方进行优化设计,然后进行不同粘结体系PBX炸药的水下爆炸试验。试验结果表明:与HTPB惰性粘结体系炸药相比,含能粘结体系应用于PBX炸药后,比冲击波能提高了12%~23%;但是由于含能粘结体系力学和工艺性能的限制,使得炸药固含量降低,降低了炸药的气泡能。总的来看,TEGDN、GAP、HTPB粘结体系的PBX炸药总能量分别达到了2.01、1.99、2.15倍TNT当量。
As the important part of polymer bonded explosive,blinders has great effect on the mechanical property andenergy characteristics.In order to research the influence of different binders on energy characteristics of PBX underwaterexplosion,the formula of each binders was carried out optimal design,then the underwater explosion experiment ofdifferent blinders PBX were conducted.The test result showed that,compared with HTPB inactive binder system explosive,the shockwave of PBX with energetic binder system increases by12%~23%.Meanwhile the bubble performance ofexplosive with energetic binders is decreased because the mechanical property and processing performance of energeticbinders were poor which lead the decrease of solid-content.In summary,the TNT equivalent of explosive with TEGDNbinder,GAP binder and HTPB binder arrived2.01,1.99and2.15respectively.
