摘要：

To improve the combustion and ignition performances of ammonium perchlorate(AP)-based composite solid propellants, the manganese alginate film was prepared by an ion exchange method, and the nano-Mn 3 O 4 composite catalyst was obtained after calcinations of the film. The effect of nano-Mn 3 O 4 composite catalyst on the thermal decomposition performances of AP was studied. The morphology and structure of prepared nano-Mn 3 O 4 composite catalyst were characterized by scanning electron microscopy(SEM), Fourier transform infrared(FT-IR)spectroscopy, X-ray photoelectron spectrometer(XPS)and X-ray diffractometer( XRD). Results show that after the exchange of manganese ion, sodium alginate becomes manganese alginate, formed film surface is smooth and dense. After calcinations at 400℃, in situ-grown nano-Mn 3 O 4 particle is loaded onto the carbonized alginate skeleton. The catalytic effect on AP enhances with increasing the content of nano-Mn 3 O 4 composite catalyst and the exothermic rate also increases significantly. Compared with pure AP, the decomposition temperature of AP decreases by 89.1℃ when the content of nano-Mn 3 O 4 composite catalyst is 3%. © 2018, Editorial Board of Chinese Journal of Energetic Materials.
