CL-20对硝酸酯炸药性能的影响

摘要

以HMX硝酸酯炸药配方为基础,用六硝基六氮杂异伍兹烷(CL-20)部分替代HMX,计算了含CL-20的硝酸酯炸药的密度、爆热和爆速,并与测试结果进行了对比;测试了其机械感度.结果表明,随着CL-20含量的增加,硝酸酯炸药的实测密度、爆热、爆速均明显增加;当CL-20质量分数为50%时,硝酸酯炸药的实测密度、爆热和爆速分别为1.907g/m3、6826J/g和9125m/s,撞击感度由34%提高到40%,摩擦感度由28%提高到60%.%Based on the formulation of nitrate ester explosive with HMX and replacing HMX by CL-20, the density, heat of detonation and detonation velocity of nitrate ester explosive with CL-20 were calculated and compared with the test results.Its mechanical sensitivities were tested.The results show that the measured density, heat of detonation and detonation velocity of the explosive are obviously increased with increasing the content of CL-20.When the mass fraction of CL-20 is 50%, the measured density, heat of detonation and detonation velocity of the nitrate ester explosive are 1.907g/m3, 6826J/g and 9125m/s, respectively, while the impact sensitivity increases from 34% to 40%, and the friction sensitivity increases from 28% to 60%.
