Mechanism Of Two Typical Binders Br And F-2604 On Thermal Decomposition Of Hmx

DSC-TG-FTIR-MS coupling technology was used to study the mechanism of two typical binders, that is, BR and F-26(04), on the thermal decomposition behavior of the HMX crystal. The results show that both BR and F-2604 can induce premature decomposition of HMX and increase the activation energy of HMX. Especially in the case of HMX/BR particles, the decomposition temperature is the lowest, but the activation energy is the highest. Based on the results of DSC-TG-FTIR-MS, it is found that the rapid mechanism of binder and active intermediate products inhibits the reaction of relatively inert intermediate products and prolongs the continuous generation time of gas products in the composite particles, which delays the decomposition of HMX to a certain extent. This study is helpful for us to better understand the thermal decomposition behavior of HMX composite particles and provides reference for the application of high-energy composites.
