Mechanism of Two Typical Binders BR and F₂₆₀₄ on Thermal Decomposition of HMX.

ABSTRACT: DSC-TG-FTIR-MS coupling technology was used to study the mechanism of two typical binders, that is, BR and F₂₆₀₄, on the thermal decomposition behavior of the HMX crystal. The results show that both BR and F₂₆₀₄ 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.
