Preparation method of high-performance composite bulletproof plate

The invention discloses a preparation method of a high-performance composite bulletproof plate. The method comprises the following steps of adding soluble aluminum salt into deionized water, then adding ammonia water slowly, standing for 1-3h, adding a dispersing agent into aluminium hydroxide turbid liquid, performing ultrasound reaction for 10-30min to obtain turbid dispersion liquid; adding graphene particles into absolute ethyl alcohol, mechanically stirring until forming a dispersive effect, and then performing sealing ultrasound reaction for 20-30min to obtain activated graphene turbid liquid; slowly adding the activated graphene turbid liquid into the turbid dispersion liquid, stirring uniformly, and then performing gradient pressure reducing distillation reaction for 5-8h to obtainviscous liquid; putting the viscous liquid into a mold to sinter for 10-15h, cooling naturally, then adding the viscous liquid into a polymethyl methacrylate solution to perform ultrasound reaction for 2-5h, taking out the m
