Abstract

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 mixture, then drying rapidly, performing gradient sintering for 10-12h, and cooling to obtain the high-performance composite bulletproof plate. The high-performance composite bulletproof plate can be used for solving the problem that current whole performance is relatively low, has a good bulletproof effect, improves the bulletproof resistance effect greatly, and forms relatively rigid and soft synergistic protection simultaneously.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a preparation method of a high-performance composite bulletproof board. Background technique [0002] The existing ceramic composite bulletproof board is mainly composed of a bulletproof backboard and multiple bulletproof ceramic blocks arranged on the bulletproof backboard. Although the cost performance of the existing ceramic composite bulletproof board is high, at least there are still some The following problems: first, the overall weight of the existing ceramic composite bulletproof panels is generally high; second, in the existing ceramic composite bulletproof panels, the bulletproof performance of the junction between the bulletproof ceramic blocks is very weak; third, The bulletproof principle of the existing ceramic composite bulletproof board is to rely on increasing the bullet penetration resistance to achieve the purpose of bulletproof. This bu...
