Embodiment 1
[0036] A high-strength butylated hydroxyl propellant and a preparation method thereof mainly comprise the following process steps:
[0037] Step (1), take the raw material according to the following mass percentage content:
[0038] 6.934% HTPB, 0.2% MAPO, 3.58% DOS, 5% AL, 10% RDX, 73.5% AP;
[0039] Step (2), mixing the raw materials described in step (1) uniformly at 60°C;
[0040] Step (3), weighing 0.586% IPDI and adding it to the mixture made in step (2) to continue mixing under vacuum at 60°C for 60min;
[0041] Step (4), weighing 0.2% vinylcyclohexene diepoxide and adding it to the mixture made in step (3) and continuing vacuum mixing at 60° C. for 15 minutes to make propellant slurry;
[0042] Step (5), the propellant slurry prepared in step (4) is poured into the engine casing or various molds using a vacuum pouring system, and cured in an oven at 70°C for 96 hours to obtain a high-strength butylated hydroxyl propellant.
