    摘要:

    采用DSC、GJB5891.22, 24, 25, 27-2006方法研究了掺杂碳纳米管(CNTs)及碳黑(CB)对高氯酸·四氨·双(5-硝基四唑)合钴(Ⅲ)(BNCP)的热、撞击、摩擦、火焰、静电火花和激光感度的影响。结果表明:(1)碳纳米管和碳黑能够降低半导体激光起爆BNCP发火阈值;(2)掺杂5% CNTs和5% CB的BNCP的50%激光发火阈值分别为13.76和5.06 mJ;(3)在加热速率为10 ℃·min-1的条件下,BNCP、BNCP/CNTs、BNCP/CB主要放热分解峰温度分别为289.87,277.75,276.67 ℃;(4)撞击、火焰感度:BNCP > BNCP/CNTs > BNCP/CB;摩擦感度:BNCP/CB > BNCP/CNTs > BNCP;静电火花感度:BNCP/CB > BNCP > BNCP/CNTs。

    Abstract:

    Sensitivities to heat, laser, impact, friction, flame and electrostatic spark for tetraamnine bis(5-nitrotetrazolato) cobalt(Ⅲ) perchlorate (BNCP) and BNCP doped with carbon nanotubes (CNTs) and carbon black(CB) were measured and studied by DSC, laser sensitivity test and standardization methods GJB5891.22, 24, 25, 27-2006. Results show that (1) CNTs and CB make the semiconduction laser initiation threshold value of BNCP decrease; (2) the 50% ignition threshold values of BNCP doped with 5% CNTs and 5% CB are 13.76 mJ and 5.06 mJ, respectively; (3) the peak temperature of main exothermic decomposition reaction at a heating rate of 10 ℃·min-1 for BNCP, BNCP/CNTs 10-20 nm mixture and BNCP/CB mixture are 289.87 ℃, 277.75 ℃ and 276.67 ℃, respectively; (4) the sensitivity decreases in the order BNCP > BNCP/CNTs > BNCP/CB for impact and flame sensitivity, BNCP/CB > BNCP/CNTs > BNCP for friction sensitivity, and BNCP/CB > BNCP > BNCP/CNTs for electrostatic spark sensitivity.
