HMX基O/W型悬浮油墨的喷墨打印成型及性能
Inkjet Printing Molding and Properties of HMX-based O/W Type Suspension Ink
摘要
Abstract
In order to explore the feasibility of combining emulsion explosive ink and inkjet printing process,an oil-in-water(O/W)two-component binder system was designed through ethyl acetate solution of fluorocarbon resin(FEVE)as oil phase and polyvinyl alcohol(PVA)aqueous solution as water phase.The micro-nano HMX was selected as the main explosive to prepare O/W suspension explosive ink for the inkjet printing.Furthermore,the density,morphology,mechanical properties,thermal safety performance,impact sensitivity and friction sensitivity of the printed samples were characterized by electron density tes-ter,laser confocal microscope,scanning electron microscope(SEM),X-ray diffractometer(XRD),nanoindentation instrument,simultaneous thermal analysis TG-DSC,impact and friction sensitivity tester.The detonation velocity and critical size of the print-ed samples were tested.The results show that the surface of the inkjet printed sample is relatively flat,the average line roughness is 7.346 μm,and the internal particle distribution is compact.The crystal type of HMX particles would not change during printed process,and the printed samples display good the thermal stability and the mechanical properties.The measured density of the sample is 1.5326 g·cm-1(83%theoretical maximum density).The impact energy and the friction load of the printed sample are 7 J and 144 N,respectively.The detonation velocity of the printed sample with size of 1 mm×1 mm is 7076 m·s-1 and the criti-cal size is 1 mm×0.087 mm.Therefore,the samples prepared through inkjet printing of HMX based emulsion explosive ink have excellent safety performance and micro-scale detonation performance.关键词
