摘要

基于氧化剂/燃料一体化设计理念，在对Al颗粒进行表面修饰的基础上，采用声共振和喷雾干燥技术成功制得了多尺度界面可调半嵌入型Al/RDX和全嵌入型Al@RDX复合颗粒。通过扫描电子显微镜(SEM)等技术对复合颗粒的形貌、密度和燃烧热进行表征，并利用热红同步热分析仪(DSC-TG-FT-IR)对其热分解过程及气相产物进行了研究。研究结果表明：与机械混合物相比，复合颗粒密度基本保持不变，但燃烧热分别提升至17.31 kJ/g和18.82 kJ/g. DSC结果表明两种方式均可提高RDX的热分解放热量：铝粉嵌入未改变RDX的气相分解产物种类，但其中HCHO的相对含量有所增加：嵌入铝粉后RDX第一分解阶段均由二维成核增长模型(A2)转变为链断裂模型(L2)：全嵌入型Al@RDX的第二分解阶段则转变为自催化模型(AC)。

Abstract

Based on the integrated design concept of oxidant/metal fuel (Al) in propellants and the surface modification of aluminum particles

the multi-scale interface-tunable semi-embedded Al/RDX and fully-embedded Al@RDX composites were prepared by resonant acoustic mixing and spray drying. The morphology

true density and heat of combustion of the composites were characterized by scanning electron microscopy (SEM) and other techniques

and the thermal decomposition process and its gas products were studied by simultaneous thermal analyzer (DSC-TG-FT-IR). The results showed that compared with the mechanical mixture

the true density of the composites remained basically unchanged

but the heat of combustion of these two composites was higher

which were 17.31 kJ/g and 18.82 kJ/g. The DSC results showed that the heat of thermal decomposition of RDX can be increased by these two ways. Although the embedding of aluminum particles does not change the types of gas-phase products of RDX decomposition

it is more conducive to generate more HCHO. After the embedding of aluminum particles

the first decomposition stage of RDX changed from the random nucleation model (A2) to the random chain scission model (L2)

while the second decomposition stage of the fully-embedded Al@RDX composites was transformed into the autocatalytic model (AC).
