ADN与AP/RDX/Al相互作用及机理

Interaction of ADN with high energy components and its mechanism

采用高能氧化剂ADN部分代替AP,分别设计了AP/RDX、AP/RDX/Al、ADN/AP/RDX、ADN/AP/RDX/Al四种组分体系,利用差示扫描量热技术,研究ADN与高能组分的相互作用,尤其是对组分体系放热量的影响。结果表明,ADN的加入使ADN/AP/RDX组分体系的放热量增加了1.6倍,使ADN/AP/RDX/Al组分体系的放热量增加了1.68倍。同时,采用热-红-质联用技术,通过对分解产物的结构鉴定及整个过程中红外光谱强度和质谱质子流强度变化规律的研究,发现ADN的加入导致组分体系热分解反应生成更多的标准摩尔生成焓小的生成物,使得热分解反应的焓值更小,放热量增加。

Four energetic systems:AP(Ammonium Perchlorate)/RDX(Cyclotrimethylene Trinitramine),AP/RDX/Al(Aluminum),ADN(Ammonium Dinitramide)/AP/RDX,ADN/AP/RDX/Al,have been designed by partially replacement of AP using high energy oxidizer ADN.The interaction of ADN and high energy components,especially the effect of ADN on the heat release of the mentioned energetic systems were studied by differential scanning calorimetry(DSC)technique.The results show that the heat release of ADN/AP/RDX is increased by 1.6 times,whereas the heat release of ADN/AP/RDX/Al system is increased by 1.68 times,with the addition of ADN.Meanwhile,by using the coupling TG/DSC-FTIR-MS technique,we found that the addition of ADN result in the thermal decomposition reaction with more gaseous products generation and smaller standard molar enthalpy.By identifying the structure of the decomposed products and studying the intensity variation of the infrared spectrum,and mass spectrum protons of the entire process,it has been shown that AND could reduce the reaction enthalpy of thermal decomposition reaction and increase the heat release of the energetic systems.
