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 specifically relates to a method for preparing a high-performance composite bulletproof board. Background technique [0002] The existing ceramic composite bulletproof board is mainly composed of a bulletproof backboard and a plurality of bulletproof ceramic blocks arranged on the bulletproof backboard. Although the existing ceramic composite bulletproof board is very cost-effective, the ceramic composite bulletproof board still exists at least The following problems are as follows: First, the overall weight of the existing ceramic composite bulletproof board is generally high; second, in the existing ceramic composite bulletproof board, the ballistic performance of the joint between the bulletproof ceramic blocks is very weak; third, The bulletproof principle of the existing ceramic composite bulletproof board is to achieve the purpose of bulletproof by increasing the penetration resi...
