▎ 摘  要

NOVELTY - Preparing graphene-based composite ballistic-resistant material, comprises (i) carrying out graphene or graphene oxide coupling treatment by organic chromium complexes, silanes, titanate coupling agent or aluminum acid compound as a coupling agent, and using water and ethanol as solvent; (ii) preparing resin dispersant; and (iii) processing coupling agent added with graphene oxide or graphene to dispersant resin, or subjecting steps (i) and (ii) products to ultrasonic shearing under controlled ultrasonic power of 100-500 W, and shearing rate of 10-3000 rotations/minute, dispersing, mixing. USE - The material is useful for vehicles, ships, aircraft and military/civilian protective equipment, impact or in the preparation of impact resistant materials and/or shock-absorbing material (claimed). ADVANTAGE - The method has simple process and simple operation, is economical, strong controllability, and is suitable for large-scale industrial production. DETAILED DESCRIPTION - Preparing graphene-based composite ballistic-resistant material, comprises (i) carrying out graphene or graphene oxide coupling treatment by using organic chromium complexes, silanes, titanate coupling agent or aluminum acid compound as a coupling agent, and using water and ethanol as a solvent, adding coupling agent into solvent in a mass ratio of 0.1-10 g/100 ml, to obtain coupling agent solution, adding graphene oxide or graphene having diameter of 0.01-200 mu m and thickness of 0.3-10 nm into coupling agent solution to carry out coupling process; (ii) preparing resin dispersant by mixing polyvinylpyrrolidone or polyethylene glycol as a dispersant into resin in a mass ratio of 0.01-10:90-99.99, carrying out stirring at a high speed of 10-5000 rotations/minute, to obtain mixed resin powder scoring system; and (iii) processing coupling agent added with graphene oxide or graphene into dispersant resin in a mass ratio of 0.01-20:99.99-80, or subjecting steps (i) and (ii) products to ultrasonic shearing under controlled ultrasonic power of 100-500 W, and shearing rate of 10-3000 rotations/minute, uniformly dispersing, mixing, until dried graphite is homogeneously dispersed.
