摘要:
为了增加金属燃料与氧化剂的接触面积，提高铝热剂的燃烧性能，基于微米Al粉,采用改进的溶胶凝胶法制备出了Al/Cu2(NO3)(OH)3。XRD及SEM分析表明：Al与Cu2(NO3)(OH)3形成了以Al为核、以Cu2(NO3)(OH)3为壳的核壳结构。DSC分析表明：Al/Cu2(NO3)(OH)3在270 ℃发生放热反应。当Al和Cu(NO3)2?3H2O的摩尔比为1∶1时，样品的核壳结构包覆效果最好、放热量最大。基于Al/Cu2(NO3)(OH)3核壳材料的制备方法，通过在溶胶中加入硝化棉及溶剂，制备出了适用于喷墨打印的含能油墨，并研究了含能油墨的喷墨打印特性。利用喷墨打印装置制备直写装药，采用Cr金属桥和脉冲激光研究直写装药的点火性能。结果表明：含能油墨的连续性及流动性较好，在Cr金属桥通电或者脉冲激光能量作用下，直写装药能够发火。
Abstract:
In order to increase the contact area of metal fuel and oxidant and improve the combustion performance of thermite, the Al/Cu2(NO3)(OH)3 was synthesized by promoted sol gel method based on micron Al powder. Results from SEM and XRD show that Al/ Cu2(NO3)(OH)3 formed in a core shell structure with Al as core and Cu2(NO3)(OH)3 as shell. DSC results show that Al/Cu2(NO3)(OH)3 materials could exothermally react at 270 ℃, and the maximum heat generation and complete core-shell structure of Al/Cu2(NO3)(OH)3 were obtained when molar ration of Al and Cu(NO3)2?3H2O was 1∶1. Following the preparation process for coreshell structured Al/Cu2(NO3)(OH)3, the energetic ink, which is suitable for inkjet printing, was prepared by adding nitrocellulose and solvent into sol. The inkjet printing characteristics of energetic ink was studied. The ignition properties of direct writecharging of the energetic ink which prepared by using inkjet printing devices under conditions of Cr metallic bridge and pulse laser were also examined. The results show that, the uniformity and continuity of Al/Cu2(NO3)(OH)3 energetic ink was good, and direct write charging could be ignited by Cr metallic bridge energized or pulse laser.
