▎ 摘  要

NOVELTY - A high-concentration anti-salt spray graphene slurry has graphene content of 15-30%. USE - High-concentration anti-salt spray graphene slurry. ADVANTAGE - The high-concentration anti-salt spray graphene slurry has salt spray resistance time of 6500 hours or more at coating thickness of 80 mu m. In the slurry, the specific surface area of modified bentonite is increased by 30.5%, such that certain quality of bentonite can absorb more graphene, and the graphene concentration in the graphene slurry is increased to more than 15%. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the slurry, which involves modifying bentonite to obtain modified bentonite, mixing graphene, modified bentonite, dispersing agent and solvent, obtaining graphene-modified bentonite composite slurry, reinforcing the composite slurry by adding a reinforcing agent, and mixing resultant product with solvent and film-forming agent.
