为探讨石墨二炔(GDY)对环四亚甲基四硝胺(HMX)热分解特性的影响,制备了GDY/HMX(质量比1∶4)含能复合物,运用差示扫描量热法(DSC)和热重-红外-质谱联用技术(TG/DTG-FTIR-MS)对比研究了HMX和GDY/HMX的热分解过程;采用Kissinger法、FWO法、KAS法、Starink法、Kissinger-迭代法及Ozawa-迭代法计算HMX和GDY/HMX的表观活化能,并引入修正后的Sestak-Berggren经验方程对其热分解反应动力学模型进行重建。结果表明,GDY使HMX的表观活化能降低73.6 kJ/mol。GDY/HMX复合物的热分解过程遵循n级动力学方程f (α)= 3.04α~(0.39)(1-α)~(1.17);在GDY催化作用下,HMX热分解以C-N键断裂为主,首先释放出C_2HO和N_2O,还检测到NO、NO_2、HCN、CO、N_2、HCNO、CO_2和H_2O气体。 |

To explore the effect of graphdiyne(GDY)on the thermal decomposition characteristics of HMX,the GDY/HMX(mass ratio of 1∶4)composite energetic materials was prepared,and the differential scanning calorimetry(DSC)and the thermogravimetry coupled with Fourier transform infrared spectrometry and mass spectrometry(TG/DTG-FTIR-MS)technique were employed to investigate the pyrolysis processes of the HMX and GDY/HMX comparatively.The apparent activation energies of HMX and GDY/HMX were calculated by Kissinger,FWO,KAS,Starink,Kissinger-iterative,and Ozawa-iterative methods,and the modified Sestak-Berggren empirical equation was used to reconstruct the kinetic models of their thermal decomposition reactions.The results show that the apparent activation energy of HMX is reduced by 73.6 kJ/mol in the presence of GDY.The pyrolysis process of the GDY/HMX composite follows the n-order kinetic equation f(α)=3.04α~(0.39)(1-α)~(1.17).GDY plays a crucial role in promoting the C-N bond cleavage during HMX decomposition,leading to the release firstly of the C_2HO and N_2O.And the gaseous products including NO,NO_2,HCN,CO,N_2,HCNO,CO_2,and H_2O are also detected. |
