【 摘 要 】
In order to study the thermal decomposition characteristics of modified double-base propellant and cobalt-2 double-base propellant, their thermal decomposition process were tested with accelerating rate calorimeter(ARC). Thermal decomposition characteristic parameters were obtained by analyzing temperature-time curves, pressure-time curves and temperature rate-time curves. The kinetic parameters were calculated by velocity constant method. It is showed that the initial exothermal temperature of modified double base propel-lant is 134.8 C, E=185 kJ•mol-1. The initial exothermal temperature of cobalt-2 double-base propellant is 125.3 C, E=144.9J•mol-1. It means that the thermal stability of these two kinds of propellant are fine and the stability of modified double-base propellant is better.
