Abstract

The invention belongs to the technical field of functional ceramics, and specifically relates to a preparation method of a composite bulletproof ceramic plate. Step 1, adding aluminum hydroxide to deionized water, then adding polyvinyl alcohol, and ultrasonically reacting for 20-40 minutes to obtain aluminum hydroxide dispersion liquid; Step 2, adding the aluminum hydroxide dispersion to a vacuum distillation kettle for 1-3h underpressure distillation to obtain a viscous liquid; Step 3, adding the viscous liquid to the mold and evaporating with slight heat for 20-30min, and solidifying to obtain Precursor plate; step 4, put the precursor plate in the reactor to heat and pressurize for 3-8 hours to obtain the first ceramic plate; step 5, put the dense ceramic plate in absolute ethanol, and then add graphene powder for ultrasonic React for 3-6 hours to obtain the second ceramic plate; step 6, put the second ceramic plate in the reaction kettle for a second heating and pressurizing reaction for 5-7 hours to obtain the composite bulletproof ceramic plate. The invention solves the problem of low overall performance of the existing bulletproof plate, and has the characteristics of bulletproof effect, good connection of the ceramic plate and long service life.

Description

technical field [0001] The invention belongs to the technical field of functional ceramics, and in particular relates to a preparation method of a composite bulletproof ceramic plate. Background technique [0002] Some ceramic composite bulletproof panels are mainly composed of a bulletproof backplane and multiple bulletproof ceramic blocks located on the bulletproof backplane. Although the existing ceramic composite bulletproof panels are very cost-effective, there are at least the following types of ceramic composite bulletproof panels: Several problems: first, the overall weight of the existing ceramic composite bullet-proof panels is generally on the high side; second, in the existing ceramic composite bullet-proof panels, the ballistic performance of the joints between the bulletproof ceramic blocks is very weak; third, the current The bulletproof principle of the ceramic composite bulletproof plate relies on increasing the penetration resistance of the bullet to achiev...
