In order to study the properties of 3,3'-diamino-4,4'-azoxyfurazan (DAAF)-based insensitive high polymer bonded explosives (PBX), three kinds of DAAF-based PBXs (DAAF/EVA (95/5), DAAF/Viton A (95/5) and DAAF/F₂₃₁₁ (95/5)) were prepared by water suspension coating technique. The morphology structure, crystal form, thermal decomposition characteristic and mechanical sensitivity were analyzed by scanning electron microscopy (SEM), X-ray diffractometer (XRD), differential scanning calorimeter (DSC), impact and friction sensitivity apparatus. The fast and slow cook-off behaviors were examined. The DAAF/F₂₃₁₁ was well coated which had a smooth spherical shape with 450 μm in diameter, while DAAF/EVA and DAAF/VitonA were poorly coated with rough surface. The exothermic peak temperature of DAAF/F₂₃₁₁ was 0.9 ℃ lower than that of DAAF (when the heating rate was 10 ℃·min^-1). The activation energy and the critical temperature of thermal explosion of DAAF/F₂₃₁₁ was 12.14 kJ·mol^-1 and 8.29 ℃ higher than that of the raw DAAF, respectively. According to the GJB772A-1997 method, the impact sensitivity H₅₀ of the three DAAF-based PBXs were greater than 100 cm, and the friction sensitivity was 0. The response level of the fast and slow cook-off tests was burning, which satisfied the safety requirements for insensitive ammunition.
