    摘要:

    为了推动含能材料的绿色化发展,提高含能材料的热稳定性和能量性能,研究通过偶氮噁二唑环嵌段插入分子的方法,电化学合成了四唑联1,3,4-噁二唑基偶氮含能化合物(H2AzAOT),及其金属盐(Mn-AzAOT,Zn-AzAOT,Pb-AzAOT)。利用X射线单晶衍射、红外光谱、核磁等方法对H2AzAOT及其金属盐进行了结构表征;采用差式扫描量热法对其热稳定性进行研究;采用标准BAM法测试了其撞击感度和摩擦感度;采用EXPLO5程序模拟得到了爆轰性能。结果表明:H2AzAOT及其金属盐具有优异的物化性质。其中H2AzAOT的理论爆速(D)为8511 m·s-1,爆压(p)为28.9 GPa,Pb-AzAOT的D为8934 m·s-1,p为29.7 GPa。这两者的爆轰性能均显著优于传统耐热钝感含能材料六硝基茋(HNS)(D = 7612 m·s-1,p = 24.7 GPa)

    Abstract:

    In order to promote the development of high-energy material preparation technology and comply with the current trend of green and environmentally friendly development, electrochemical methods were used to prepare tetrazole-1,3,4-oxadiazole azo energetic compounds (H2AzAOT). Simultaneously, its metal salts (Mn AzAOT, Zn AzAOT, Pb AzAOT) were prepared. The overall thermal stability and energy performance of the energetic materials were improved by inserting the molecule into the azo oxadiazole ring block. The structural characterization of H2AzAOT and its metal salts was carried out using X-ray single crystal diffraction, infrared spectroscopy, nuclear magnetic resonance and other methods; The thermal stability was studied using the differential scanning calorimetry; Using BAM testing method to test impact sensitivity and friction sensitivity; Based on the actual density measured in experiments and the calculated heat of formation in the solid state, the explosion performance was simulated using the EXPLO5 program. The results indicate that H2AzAOT and its metal salts have excellent physicochemical properties. The calculated detonation velocity (D) and detonation pressure (P) of H2AzAOT (D = 8511 m s-1, P = 28.9 GPa) and Pb-AzAOT (D = 8934 m s-1, P = 29.7 GPa) are much higher than those of traditional energetic materials TNT.
