    摘要:

    采用差示扫描量热法(DSC)和热重分析(TGA)法研究了丙基硝基胍 (PrNQ)的热分解行为和非等温分解反应动力学,利用原位红外技术研究了PrNQ分子的分解机理,利用DSC实验研究了PrNQ与黑索今 (RDX),奥克托今(HMX),六硝基六氮杂异伍兹烷(CL-20),5,5′-联四唑-1,1′-二氧二羟铵 (TKX-50)的相容性。结果表明,PrNQ的熔点约为99 ℃,可应用于熔铸炸药体系。PrNQ的热稳定性良好,PrNQ的熔融和分解温度相差约137 ℃,可保证熔铸工艺的安全性。根据DSC实验,PrNQ与HMX及TKX-50的ΔTp分别为-0.3 K和1.36 K,表明其与HMX及TKX-50相容性良好。

    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 ΔTp of -0.3 K and 1.36 K, respectively.
