摘要：
In order to improve the safety performance of cyclotetramethylenetetranitramine (HMX) based cast polymer bonded explosive (PBX), a certain amount of 1, 1-diamino-2, 2-dinitroethylene (FOX-7) was substituted for HMX in the formulation. The influence of FOX-7 on the thermal stability, mechanical sensitivity, shock wave sensitivity and electrostatic spark sensitivity of the formulation was studied. The friction sensitivity of the formulation GOXL-A was lower than that of the HMX based cast PBX formulation GO-1 after the introduction of FOX-7. The response time in the fast cook-off and slow cook-off tests was delayed by 58.8% and 18.5%, respectively. The formulation had passed the EIS slow cook-off test with a heating rate of 3.3℃•h-1. The shock wave sensitivity was significantly reduced. The separator thickness (L50) was reduced by 15.7% compared with GO-1, and the 50% critical detonation pressure (p50) was increased by 9.5%. Its static spark sensitivity is significantly reduced. The 50% ignition voltage (V50) and 50% ignition energy (E50) increased by 65.3% and 187.5%, respectively. © 2019, Editorial Board of Chinese Journal of Energetic Materials. All right reserved.
