A new focus in the fields of energetic materials is on preserving high performance while enhancing manipulation safety. In this work, a special type of plastic‐bonded explosive (PBX) mixture has begun to be developed by combining a new nitramine, cis‐1,3,4,6‐tetranitrooctahydroimidazo‐[4,5‐d]imidazole (BCHMX), with the thermally stable explosives 1,3‐diamino‐2,4,6‐trinitrobenzene (DATB) and 2,2’,4,4’,6,6’‐hexanitroazobenzene (HNAB) bonded by a styrene‐butadiene rubber (SBR) binder. The studied PBXs prepared are insensitive explosives. They have been compared with Czech plastic explosives (SEMTEX 10 and SEMTEX 1H), a new Egyptian plastic explosive (EPX‐1), a Swedish plastic explosive (Sprängdeg m/46) and with analogous PBXs, filled by 1,3,5‐trinitro‐1,3,5‐triazinane (RDX), β‐1,3,5,7‐tetranitro‐1,3,5,7‐tetrazocane (β‐HMX), and cis‐1,3,4,6‐tetranitrooctahydroimidazo‐[4,5‐d]imidazole (BCHMX). The individual explosives, PETN, BCHMX, β‐HMX and RDX, have been studied as well. Thermal behavior of the pure active components has been investigated. The impact and friction sensitivities have been obtained along with the measured detonation velocities. The detonation characteristics have also been calculated using the EXPLO5 code. The relationship between performance and sensitivity to mechanical impulses has been investigated. The results have shown that DATB has a significant influence on the reduction of the sensitivity of BCHMX to a level close to TNT and much lower than all the other studied plastic explosives. In addition, the new PBX based on BCHMX and DATB has higher detonation characteristics than the commercial PBXs and TNT. The influence of DATB on BCHMX is a promising topic requiring more research for its application.

作为基于DATB或HNAB的低敏组合物的一部分的顺式1,3,4,6-四硝基八氢咪唑-[4,5-d]咪唑（BCHMX）

含能材料领域的新焦点是在保持高性能的同时提高操作安全性。在这项工作中，通过结合新的硝胺，即顺式1,3,4,6-四硝基八氢咪唑-[4,5-d]咪唑（BCHMX），已经开始开发一种特殊类型的塑料炸药（PBX）混合物。 ，其热稳定炸药1,3-二氨基-2,4,6-三硝基苯（DATB）和2,2'，4,4'，6,6'-六硝基偶氮苯（HNAB）通过丁苯橡胶（ SBR）粘合剂。所研究的PBX是不敏感的炸药。它们与捷克的塑料炸药（SEMTEX 10和SEMTEX 1H），新型的埃及塑料炸药（EPX-1），瑞典的塑料炸药（Sprängdegm / 46）以及类似的PBX进行了比较，PBX的填充量分别为1,3,5-三硝基-1,3,5-三嗪（RDX），β-1,3,5,7-四硝基-1,3,5,7-四唑烷（β-HMX）和顺式1,3,4，6-四硝基八氢咪唑-[4,5-d]咪唑（BCHMX）。还研究了单个炸药PETN，BCHMX，β‐HMX和RDX。已研究了纯活性成分的热行为。已经获得了冲击和摩擦敏感性以及测得的爆轰速度。还使用EXPLO5代码计算了爆震特性。已经研究了性能和对机械脉冲的敏感性之间的关系。结果表明，DATB对于将BCHMX的敏感性降低到接近TNT的水平具有显着影响，并且远低于所有其他研究的塑料炸药。此外，基于BCHMX和DATB的新型PBX具有比商用PBX和TNT高的爆炸特性。
