Abstract
To improve the problem that ultrafine hexanitrohexaazaisowurtzite (CL-20) is prepared by the solvent nonsolvent method, which tends to coalesce and automatically affects its thermal properties, the bonding agent @CL-20 core-shell composite energetic materials (ammonium dodecylbenzene sulfonate@CL-20, trimethylsilyl monooleate@CL-20 and boron nitride@CL-20) were prepared by water suspension method. The coated ultrafine CL-20 was characterized by an optical microscope, scanning electron microscope (SEM), Fourier transforms infrared spectroscopy (FT-IR) and differential scanning calorimetry (DSC), and its sensitivity was tested according to GJB 772-1997. The results showed that the three bonded dispersants completely coated CL-20, and the crystal form of CL-20 was still ε-. Compared with the raw material CL-20, the characteristic drop increased by 27.5cm at most and the thermal decomposition temperature increased by 4 °C.
