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, 5’-bistetrazole-1, 1’-diolate (TKX-50) were also achieved by DSC experiment. The results show that the melting point of PrNQ is around 99℃, 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 137℃, 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 ΔT_p of -0.3 K and 1.36 K, respectively.
