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.
