【摘要】 以1,3,5-三硝基-2,4-二氯苯为原料,经叠氮化、脱氮环化和加氨基三步反应合成了粒径约5μm的CL-18。用机械研磨法将CL-18细化,得到粒径为1.51μm的超细CL-18,比表面积为5.237m2/g。研究了超细CL-18的窄脉冲冲击起爆性能。结果表明,超细CL-18的最低起爆能量小于0.133 1J,50%起爆电压为0.9~1.1kV,低于相同条件下的HNS-IV,是一种适于冲击片雷管的优良炸药。更多还原

【Abstract】 CL-18with particle size of about 5μm was synthesized via three-step reaction of azide,denitrification cyclization and addition of amino using 1,3,5-trinitro-2,4-dichlorobenzene as raw material.CL-18 obtained was refined to 1.51μm by a mechanical polishing method,and its specific surface area was 5.237m2/g.The narrow pulse impact initiation performance of ultrafine CL-18 was studied.The results show that the minimum initiation energy of ultrafine CL-18 is less than 0.133 1Jand 50%initiation voltage is 0.9-1.1kV,which is less than that of HNS-IV under the same conditions.This ultrafine CL-18 is an excellent explosive which is suitable to impact slapper detonator.更多还原
