Abstract
Both thermal decomposition behaviors and non-isothermal decomposition reaction kinetics of propyl-nitroguanidine (PrNQ) were investigated by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) method. Its decomposition mechanism was stuied through in-situ FTIR spectroscopy technology and the compatibilities of PrNQ with 1, 3, 5-trinitroperhydro-1, 3, 5-triazine (RDX), 1, 3, 5, 7-tetranitro-1, 3, 5, 7-tetrazoctane (HMX), hexanitrohexaazaisowurtzitane (CL-20) and 5, 5â-bistetrazole-1, 1â-diolate (TKX-50) were also achieved by DSC experiment. The results show that the melting point of PrNQ is around 99â, which is very suitable for the application of melt-cast technology. The thermal stability of PrNQ is good and the difference between the melting point and decomposition temperature of PrNQ is about 137â, which is large enough to guarantee the safety of the melt-cast process. The compatibilities between PrNQ and HMX or TKX-50 are also excellent, with ÎTp of -0.3 K and 1.36 K, respectively. © 2020, Editorial Board of Chinese Journal of Energetic Materials.
