NOVELTY - Preparing graphene microchip-based corrosion-resistant epoxy resin powder coating involves adding graphene microchips and phenolic modified epoxy resin according to the weight ratio of 1:5-10 into the mixer, kneading and dispersing for 5 minutes to obtain graphene microchips and phenolic modified epoxy resin dispersion. The curing agent A, mica powder and barium sulfate is added to the graphene microchips and phenolic modified epoxy resin dispersion and continue kneading and dispersed for 5 minutes to obtain a loose mixture material, The loose mixture is added to the high-speed airflow impact machine, and solidified into spherical particles at high temperature. The spherical particles, epoxy resin composite powder and surfactant are mixed according to the weight ratio 10-15:30-60:2-6 into a high-speed mixer, stirring and dispersing Graphene microsheet-based corrosion-resistant epoxy powder coatings are obtained. USE - Method for preparing graphene microchip-based corrosion-resistant epoxy resin powder coating. ADVANTAGE - The method enables to prepare graphene microchip-based corrosion-resistant epoxy resin powder coating, which has sufficient corrosion resistance and aging resistance of epoxy resin powder coatings and is easy to disperse graphene to form a dense corrosion-resistant layer.
