▎ 摘  要

NOVELTY - A film comprises graphene sheets which are evenly arranged in the film structure to form a graphene layer. The thickness direction of graphene layer is same or similar to the thickness direction of the film structure. USE - Film for antistatic anti-corrosive coating (claimed). ADVANTAGE - The film utilizes graphene having high specific surface area, large diameter-to-thickness ratio, excellent electrical conductivity and excellent barrier properties which effectively improves the shielding barrier effect of the coating, anti-corrosion performance of the coating, and the structure of the film and improves the electrostatic conductivity of the coating. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) antistatic anti-corrosive coating, which comprises component (A) and component (B). The component (A) comprises 20-30 parts mass epoxy resin, 3-7 parts mass organic solvent, 0.1-1.5 parts mass surfactant dispersant, 0.01-2 parts mass graphene, 10-80 parts mass filler, 0.5-10 parts mass anti-settling agent and 0.3-0.6 part mass dispersant. The component (B) comprises curing agent; and (2) preparation of antistatic anti-corrosive coating, which involves dispersing graphene dry powder, organic solvent, epoxy resin and surfactant dispersant, dispersing to obtain graphene resin dispersion liquid, redispersing graphene resin dispersion liquid and dispersant to obtain mixed liquid, grinding the mixed liquid and adding filler and anti-settling agent.
