Effects of Two Common Binders on Decomposition Mechanism of HMX Molecule Under Linear Temperature Rise

The effects of two common binders (BR and F binder) on the thermal decomposition HMX molecules during linear heating were studied by molecular dynamics simulation. It was found that both can induce reaction earlier, promote conversion intermediate products to stable products, reduce activation energy potential barrier system. induction binder in composite system makes initial appear at interface between molecules, binder’s higher heat absorption rate absorbs a large amount released hot spots. promoting effect interaction consume excessive active particles, which inhibits further macromolecular products. results show BR prolonged duration HMX, rubber with better stability has longest Our simulation revealed action mechanism decomposition, provided new idea for studying properties high explosives.
