▎ 摘　　要

NOVELTY - High dispersed graphene microchip comprises submicron spindle-shaped calcium carbonate-supported graphene microchip. The mass ratio of the submicron spindle-shaped calcium carbonate to the graphene microchip is 0.1-10:1. USE - The high dispersed graphene microchip is useful for preparing antistatic anti-corrosion coatings (claimed). DETAILED DESCRIPTION - INDEPENDENT CLAIM are also included for: (1) preparing the high dispersed graphene microchip, comprising dispersing calcium hydroxide in water, heating the obtained mixture, adding carbon dioxide, reacting, adding graphene microchip, stopping addition of the carbon dioxide when the pH of the reaction reaches 6.5-7.5 to obtain a highly dispersed graphene microchip suspension and spray drying, where the mass ratio of the calcium hydroxide to the graphene microchip is 0.074-7.4:1; and (2) preparing the antistatic anti-corrosion coating comprising wetting the highly dispersed graphene microchip, dispersing, mixing with epoxy resin components and adding curing agent.
