Abstract
The nano-RDX-based plastic bonded explosives (PBXs) are prepared by solution–water suspension method. The thermal decomposition characteristics and the thermal stability of the as-prepared PBX are studied. The results show that the molding powder of nano-RDX-based PBX is mainly distributed in 60–30 meshes, and the molding powder of micron-sized RDX-based PBX is mainly distributed in 30–10 meshes. Compared with the micron-sized RDX-based PBX, the thermal decomposition peak temperature of nano-RDX-based PBX is lower, and the apparent activation energy is reduced by about 1.9% to 127.1 kJ mol−1. Furthermore, the gas volume of nano-RDX-based two PBX is a bit larger, which is consistent with the estimation result based on isothermal kinetics temperature. Because of the little difference, we can still get that the thermal stability of the two explosives is the same to each other.
