纳米可燃剂对HMX的热分解性能及热分解动力学参数的影响
Effect of nano-combustible agents on the thermal decomposition properties of HMX
摘要
Abstract
Using dimethyl sulfoxide as the solvent,hybrid HMX containing different proportions of nano-aluminum and nano silicon combustibles have been fabricated by ultrasonic assisted spray recrystallization.The thermal performance of the prepared particles has been characterized by X-ray diffraction (XRD) and differential scanning calorimetry (DSC).The thermal decomposition properties of the mixed particles with different proportions of nano-combustible agents have been studied using Kissinger method.The results show that compared with the pristine HMX,the activation energy Ea,activation entropy △S,activation enthalpy △H,and activation free energy △G of the modified HMX by 20％ of nano-aluminum combustibles have been decreased by 26.07 kJ/mol,19.23 kJ/mol,26.09 kJ/mol and 11.75 kJ/mol,respectively.As the content of nano-combustible agents increases,the catalytic effect becomes more and more obvious.In addition,in the same proportion,the nano-aluminum combustible agent has a better catalytic effect than the nano-silicon combustible agent.That is,the nano-combustible agent can increase the reaction rate of HMX at high temperature and has obvious catalytic effect on the thermal decomposition of HMX.关键词
