کاهش حساسیت ماده منفجره HMX با استفاده از پارافین اصلاح سطح شده و ارزیابی عملکرد آن به کمک حلال های فرا زود گداز

Being non-polar and considerably high electrical resistivity are significant drawbacks of the crystalline paraffin wax used for desensitizing energetic materials. Herein, as a practical approach to improve the wax properties, maleic-anhydride was reacted with paraffin wax in the presence of a free-radical initiator. Then, the reaction success was approved by employing Attenuated Total Reflection-Fourier Transform Infrared (ATR-FTIR) to spot carboxyl groups onto the aliphatic backbone. In addition, the thermal properties of the modified wax were investigated using differential-scanning-calorimetry and thermogravimetry analysis (DSC-TGA). Finally, to estimate the improvement in the wax polarity, an experiment was designed in which HMX coated via a two-step procedure was conducted for DSC and tribocharing tests. The second layer utilized 0.5 w% glyceline as a deep eutectic solvent (DES). In brief, our observation exhibited that the modified wax caused a 50% decrease in charge accumulation compared to the unmodified paraffin. In addition, our experimental outcomes .showed that the modified paraffin exhibited a better distribution over the substrate surface than the unmodified one.
