摘要
本文所研究的铝基液固复合燃料主要由氧化剂AP、可燃剂铝粉、敏化剂RDX、钝感剂石蜡、航空煤油、IPN和高分子粘结剂组成。采用TGA-DTA对复合燃料的热分解行为进行了研究。结果表明在氮气条件下,150℃时失重约为30%,主要为IPN和烃类的挥发;在210℃时,AP发生分解反应,失重约50%,该过程先发生相变吸热,而后AP分解放热;660℃时铝吸热发生相变。在氧气条件下,铝熔化后开始与氧气发生剧烈的放热反应,体系质量开始增加。采用SEM-EDS对复合燃料的微观形貌和表面元素分布进行了研究。电镜扫描结果表明可燃剂铝粉分为球铝和片铝两种类型,高温热解后球铝和片铝的结构遭到破坏;球铝为空心结构,热解后复合燃料形成具有气孔的块状结构。表面元素分析发现复合燃料的表面主要有C、O、N、Al等元素,没有发现Cl元素,表明AP被包裹起来。高温热解后复合燃料表面主要为Al、O、C和少量的N。
The compatibility and pyrolysis behavior of aluminum based liquid-solid compound fuel were investigated by TGA-DTA. The compound fuel lost its 30% weight before the temperature rose to 150℃. AP decomposed at 210℃ and lead to 50% weight loss. The reaction between aluminum and oxygen was accelerated at 660℃ since the melting of solid combustible agent. The total weight loss after 1000℃ pyrolysis is about 80% for nitrogen atmosphere. On the contrary, the total weight loss for oxygen atmosphere is approximate 70% because of the generation of aluminum oxide. The microscopic structures and the elementary composition of the pyrolysis products were analyzed using scanning electron microscopy-energy dispersive spectroscopy(SEM-EDS). The structures of aluminum are spherical and flaky. All these structures are destroyed after 1000℃ pyrolysis. Instead, massive structures were found in the products. Aluminum is the main element in the final pyrolysis products for all conditions. The second-most element in the product for nitrogen atmosphere is carbon. Carbon deposited accompany with the decomposition of paraffin or other organic components.
