摘要:
采用机械球磨法制备了平均粒径为93.2 nm的奥克托金/六硝基茋(HMX/HNS)纳米共/混晶炸药;用扫描电镜(SEM)、透射电镜(TEM)、X射线衍射(XRD)、红外光谱(IR)对样品进行了表征;采用DSC及 DSC-IR分析了其热分解性能,并进行了机械感度测试。结果表明,球磨后炸药的微观形貌呈类球形,粒度呈正态分布;机械球磨作用并未改变炸药原有的分子结构和表面元素,但XRD测试结果表明球磨后的HMX/HNS有新晶相生成;HMX/HNS的热分解活化能为328.7 kJ/mol,较原料HMX和HNS分别高45.09和125 kJ/mol,说明HMX/HNS具有更好的热稳定性;HMX/HNS热分解的主要产物为CO2和N2O,并有少量的NO和H2O;特性落高(H50)大于90 cm,摩擦感度爆炸百分比(P)为8%,机械感度低于HMX和HNS,显示HMX/HNS具有良好的安全性。
Abstract:
Nano octogen/2,2’,4,’4,6,6’-hexanitro-stilbene (HMX/HNS) co/mixed crystal explosive with an average particle size of 93.2 nm was prepared by mechanical ball milling method. The sample was characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and infrared spectrum(IR). Its thermal decomposition properties were analyzed by DSC and DSC-IR, and the mechanical sensitivity test was carried out. The results show that the micromorphology of the explosive is spherical and the particle size is normal distribution, the mechanical ball milling does not change the original molecular structure and surface element of the explosive, but the XRD test results show that HMX/HNS has a new crystalline phase after ball milling. Its activation energy of thermal decomposition is 328.7 kJ/mol, which is 45.09 and 125 kJ/mol higher than that of raw materials HMX and HNS,respectively, indicating that HMX/HNS has better thermal stability. The main products of thermal decomposition of HMX/HNS are CO2 and N2O, with a small amount of NO and H2O. The characteristic drop height (H50) is more than 90 cm and the friction sensitivity explosion percentage (P) is 8%, the mechanical sensitivity is lower than that of HMX and HNS, revealing that HMX/HNS has a good safety.
