零氧平衡CL-20/AP复合含能材料的制备及表征
Preparation and Characteristics of CL-20/AP Composite Energetic Materials with Zero Oxygen Balance
摘要
Abstract
To adjust the oxygen balance of 2,4,6,8,10,12-hexanitro 2,4,6,8,10,12-hexaazaisowurtzitane (CL-20),and further improve its energy utilization efficiency,the CL-20/ammonium perchlorate(AP) composite energetic material with zero oxygen balance was prepared by emulsion method.The factors affecting the emulsion stability were studied.The morphology,structure and properties of the material were characterized by scanning electron microscope(SEM),X-ray diffraction(XRD),differential scanning calorimeter and impact sensitivity test.The results show that when the dosage of the surfactant tween-80 is 0.56 ％ of the total mass of AP and CL-20,the stable O/W structure can be formed and the emulsion can keep good stability within 48h.The micron scale hollow spherical α-CL-20 crystals are attached to the AP crystal surface and both can be full contacted.The CL-20/AP composite energetic materials have only one exothermic peak at 243.38℃,and the heat released reaches 1 538.83J/g.Compared with the raw material CL 20,the heat released increases by 60.7％.The characteristic drop height H50 of impact sensitivity of CL-20/AP composite energetic materials is 45 cm,and increases by 32 cm compared with the raw material CL-20,revealing that the safety performance of CL-20 is significantly improved.关键词
