摘要
钝感传爆药作为钝感弹药研究的关键技术之一,深受国内外研究者的重视。传爆药对弹药系统的安全可靠性起着至关重要的作用和影响。从美国及其他军事强国批准使用的和大量研制的传爆药情况看,表明高能化是传爆药今后的主要趋势,采用的途径主要有:应用高能量密度的材料炸药,如HNIW、DNTF等以提高传爆药的能量水平;合成了聚叠氮聚合物用作传爆药中的活性粘结剂、增塑剂,以提高传爆药的性能;引入分子间混合新技术、纳米技术、分子固体技术等以降低药剂制备过程中因界面效应造成的能量损失。为了获得高能钝感传爆药的基本方法,就是选择高能密度材料作为主体炸药,选择吸附作用强、结合能大的包覆剂。
     论文主要通过分子动力学(MD)模拟体系模拟和计算以高聚物粘结炸药(PBX)为主的多系列各类型高能复合材料的结构和性能。以HNIW基高聚物粘结PBX为例,通过“吸附包覆”型MD模拟,探讨高聚物粘结剂及其浓度以及温度对PBX的力学性能、结合能和爆炸性能的影响;比较了由不同粘结剂构成的PBX的平衡结构、结合能、力学性能和爆炸性能的差异,比较并选择性能优良、粘结效果好的粘结剂。对Estane5703、EVA7350M及F2314与ε-HNIW分子间相互作用进行探讨,对粘结剂进行优选。运用分子动力学软件中的DICOVER模块,以COMPASS力场,运用量子化学(QM)方法,结果表明,三种粘结剂与ε-HNIW结合能顺序为:ε-HNIW/ Estane5703>ε- HNIW/EVA7350M>ε- HNIW/ F2314,PBX体系内分子作用前后ε-HNIW分子结构未发生大的改变。
     最后对传爆药ε-HNIW探讨了各种工艺条件对包覆效果的影响,采用水悬浮制备法制备了ε-HNIW基传爆药。结果表明,粘附功计算结果和DSC实验结果证实MD方法可优选结合能大,相容性好的粘结剂。
Insensitive booster as insensitive ammunition research is one of the key technologies, bydomestic and foreign researchers. Booster for ammunition reliability and security in systemplays a vital role and influence. From the United States and other military powers approvedfor use and a large number of booster explosive situation, show high energy is the future trendof booster, The main methods of Application of high energy density materials, explosives,such as HNIW, DNTF etc in order to improve the booster explosive energy levels; polyGlycidyl Azide Polymer used as a booster in the active bonding agent, plasticizer, in order toimprove the performance of booster; the introduction of molecular mixing among newtechnology, nanotechnology, molecular solid technology to reducing agent in the preparationprocess of the energy loss caused by the interface effect. In order to obtain the insensitive highexplosive medicine basic method, is to choose the high energy density materials as the mainexplosive, selective adsorption action strong, binding energy of the coating agent.This paper mainly through molecular dynamics ( MD ) simulation system simulation andcalculation to the polymer bonded explosive ( PBX ) of the series of various types ofcomposite material structure and properties. HNIW based polymer bonded PBX as anexample, through the" absorption coating" type MD simulation of polymer, binder and itsconcentration and temperature on the mechanical properties of PBX, the binding energy andexplosion performance; compare different binders by PBX balance structure, binding energy,mechanics and explosion properties of difference, compare and the choice of excellentperformance, good adhesive bonding effect. On Estane5703, EVA7350M and F2314and with HNIW molecular interaction are discussed, the binder is preferred. Using molecular dynamicssoftware DICOVER module, COMPASS force field, using quantum chemistry ( QM ) method,the results show that, three kinds of binder and E - HNIW binding to order: with HNIW /Estane5703 > HNIW / EVA7350M > e - E - HNIW / F2314, PBX system before and aftertreatment with HNIW molecular molecular structure did not produce big change.
     At the end of the booster with HNIW explores a variety of process conditions on thecoating effect, using aqueous suspension preparation prepared with the HNIW base booster.The results show that, the work of adhesion of the calculation results and the experimentalresults confirm that MD DSC method can preferably in conjunction with big, goodcompatibility of the binder.
