2，4-MDNI/DNTF eutectic system was prepared by using 1-methyl-2，4-dinitroimidazole （2，4-MDNI）， a high energy insensitive explosive， to improve the high sensitivity and high melting point of the dynamite carrier 3，4-dinitrofuroxan （DNTF）. The melting and liquefaction processes of 2，4-MDNI/DNTF with different ratios were studied by differential scanning calorimetry （DSC）， and the T-x phase diagram was established. The melting and decomposition processes of 2，4-MDNI， DNTF and 2，4-MDNI/DNTF eutectic at different heating rates were studied. The kinetic parameters of 2，4-MDNi， DNTF and their eutectic were calculated by flynn-wall-Ozawa method， Doyle method and Kissinger method respectively. XRD and SEM analysis were carried out for the three substances. The hyposensitivity of 2，4-MDNI to DNTF was studied by sensitivity test.The detonation properties of 2，4-MDNI/DNTF eutectic were calculated by using EXPLO5. The results show that the molar composition of 2，4-MDNI/DNTF eutectic is 51∶49， and the average melting point is 92.7 ℃. As the heating rate increases， both melting and decomposition reactions are delayed. The activation energy E_a and pre-exponential factor A of thermal decomposition of eutectic are 146.0 kJ·mol^-1 and 4.09×10¹³， respectively. In XRD test， the low eutectic of 2，4-MDNI/PETN generates a new diffraction peak at 2θ=18.60°. The microstructure of the solidified surface is obviously better than that of DNTF. The impact and friction sensitivities of 2，4-MDNI are both 0%.The impact sensitivity and friction sensitivity of eutectic are 64% and 52%， respectively. The theoretical density of 2，4-MDNI/DNTF eutectic is 1.844 g·cm^-3， and the calculated detonation velocity is 8705 m·s^-1. The eutectic of 2，4-MDNI and DNTF was prepared with ideal melting point and good thermal stability. At the same time， the sensitivity of DNTF can be significantly reduced while maintaining its high energy level.
