Abstract
Ferrocene‐based (Fc‐based) burning rate catalysts (BRCs) play an essential role in the solid rocket propellants. However, the migration problem during curing and storage limits their applications. To retard the migration problems of Fc‐based BRCs and to increase the burning rate (BR) of AP‐based propellants, Fc‐based esters compounds (Es‐Fcs) were synthesized. The synthesized Es‐Fcs were characterized by X‐ray diffraction, proton nuclear magnetic resonance (1H NMR),13C NMR and Fourier transform infrared (FT‐IR) spectroscopy. The electrochemical behaviors of Es‐Fcs were investigated by cyclic voltammetry (CV). The BR catalytic activity of Es‐Fcs on thermal decomposition of AP were examined by thermogravimetry (TG). Thermal analysis results showed that these Es‐Fcs had good BR catalytic effects on thermal decomposition of AP. It was found that the anti‐migration performance of Es‐Fcs were better than catocene and Fc.
