摘要:为了实现CA/CL-20点火起爆序列的微型化制备，基于喷墨打印技术，以叠氮化钠墨水、铜盐墨水、CL-20墨水为前驱体，采用分层打印的方式在SCB上原位制备了叠氮化铜（CA）和CL-20炸药，制成SCB+CA+CL-20微型化点火起爆序列，并通过发火性能试验及RDX雷管-铅板起爆试验对其性能进行了研究。结果表明：原位制备的CA在作用过程中发生了爆燃转爆轰，且能够点燃CL-20；SCB+CA+CL-20样品的点火持续时间超过6 ms，而SCB裸桥和SCB+CA样品均小于2 ms，表明打印的CL-20未发生爆轰，而是以燃烧为主；SCB+CA+CL-20点火起爆序列能够可靠起爆RDX雷管，并将铅板炸穿。
Abstract:In order to achieve the miniaturization preparation of CA/CL-20 ignition and initiation sequences, based on inkjet printing technology, sodium azide ink, copper salt ink, and CL-20 ink were used as precursors to prepare copper azide (CA) and CL-20 explosives in situ on SCB through layered printing, resulting in the SCB+CA+CL-20 miniaturized ignition and initiation sequences, and its performance was studied through ignition performance test and RDX detonator-lead plate detonation test. The results show that the CA prepared in situ undergoes deflagration to detonation transition during the reaction process, and can ignite the CL-20; The ignition duration of the SCB+CA+CL-20 sample is more than 6 ms, while those of the SCB bare bridge and SCB+CA samples are both less than 2 ms, indicating that the printed CL-20 did not undergo detonation, but mainly burned; The SCB+CA+CL-20 ignition and initiation sequence can reliably initiate the RDX detonator and penetrate the lead plate.
