Abstract

Composite explosives based on 1,3,5-trinitro-1,3,5-triazinane (RDX) with different additives were prepared by electrospray method. The morphology and particle size, crystal structure and thermal decomposition properties were characterized by the scanning electron microscope, the laser particle size analyzer, the X-ray diffractometer and the differential scanning calorimeter, respectively. In terms of the morphologies of the composites, the particle sizes were in the range of 1–4 μm. The crystal types of the RDX/PVAc, RDX/PVB, RDX/F2604 and RDX/DOS composites were similar to those of raw RDX. The apparent activation energy (145.678 kJ mol−1) and the critical temperature (486.49 K) of the RDX/PVB composites were found to be the lowest among all involved composites. The compatibility of the RDX/F2604 and RDX/DOS composites was both in level A. The thermal stabilities of the composites decreased in the order RDX/F2604 > RDX/DOS > RDX/PVAc > RDX/PVB.
