    摘要:

    为了降低CL-20感度,采用喷雾结晶工艺将钝感炸药NQ包覆在CL-20表面,制备CL-20/NQ复合含能微球。使用扫描电子显微镜(SEM)、差示扫描量热法(DSC)、X-射线衍射(XRD)、撞击感度仪对其进行形貌、热稳定性、晶型、撞击感度进行测试分析。结果表明:NQ呈球体团聚,NQ成功地包覆在CL-20表面,所得CL-20/NQ复合颗粒为球形,粒径约为20 μm,包覆后CL-20晶型保持为ε型,与CL-20原料相比,CL-20/NQ复合含能微球的活化能提高了72.62 kJ/mol,热稳定性大大提升,撞击感度与CL-20原料、CL-20/NQ简单混合物相比,特性落高分别提升32.65 cm、10.9 cm,机械感度降低。

    Abstract:

    In order to enhance insensitivity of CL-20, CL-20/NQ composite energetic microspheres were prepared by coating the NQ on the surface of CL-20 employing spray crystallization process. Scanning electron microscopy (SEM), differential sanning calorimeter (DSC), X-ray diffraction (XRD) and impact sensitivity instrument were employed to investigate the morphology, thermal stability, crystal form and impact sensitivity of CL-20/NQ composite energetic microspheres. Results show that after coating, NQ was spherical agglomeration and successfully coated on the surface of CL-20. The prepared CL-20/NQ composite particles were spherical in shape, approximately 20 μm in size and ε-CL-20 crystal in form. The activation energy of CL-20/NQ composite energetic microspheres was 72.62 kJ/mol higher than that of raw CL-20, and this meant thermal stability of CL-20/NQ greatly improved. The mechanical sensitivity of CL-20/NQ was very low. In impact sensitivity tests, special height of CL-20/NQ composite energetic microspheres increased by 32.65 cm and 10.9 cm compared with raw CL-20 and CL-20/NQ mixture, respectively.
