In order to modify the melting point of DNTN,a new type of non-sensitive explosive TNTON was used to prepare the TNTON/DNTN eutectic system.The melting and liquefaction processes of TNTON/DNTN with different proportions were studied by DSC,and the T-x phase diagram was established,as well as the melting and decomposition processes of TNTON/DNTN eutectic at different heating rates.The detonation performance of TNTON/DNTN eutectic was calculated using EXPLO-5 software.The results show that the mass composition of the lowest eutectic of TNTON/DNTN is 72.78:27.22,and the average melting point is 65.4 ℃.With the increase of heating rate,the melting and decomposition reactions are delayed.The theoretical density of TNTON/DNTN eutectic is 1.838 g/cm,the calculated detonation speed is 8 499 m/s.TNTON and DNTN can reduce the melting point and maintain the high energy level of the low eutectic compound,which is expected to be applied in the field of liquid phase carrier explosives.
