[0058] The method for preparing propellant in the present embodiment is as follows:
[0059] (1) Treatment of oxidizing agent: take 0.45 g of ammonium perchlorate, and grind it with a mortar before use, so that the granular ammonium perchlorate becomes powder, so that it can be evenly mixed with other components.
[0060] (2) ①Synthesis of monomer ferrocenyloxyethyl (meth)acrylate: at room temperature, add 3.6g (14.5mmol) of ferrocenemonoyl chloride into a two-necked flask, add 40mL CH 2 Cl 2 , (meth)hydroxyethyl acrylate 1.9mL (14.5mmol), triethylam...
