NOVELTY - Preparing zinc-coated graphene oxide composite anti-corrosion coating, comprises e.g. (i) preparing graphene oxide-doped zinc coating using the continuous coating device and the brush plating process on the base column, setting the voltage to 10 V constant voltage, and the scraper is automatically pressed on the surface of the base cylinder and scraping off the doped coating on the surface of the base cylinder, repeating the generation and scraping operation of the above-mentioned coating layer to obtain solid bulk graphene oxide powder doped zinc composite material, taking out obtained solid block and washing with distilled water and drying, and then placing in a ball mill and grinding into powder to obtain zinc-coated graphene oxide powder, and (ii) mixing 8-15 pts. wt. zinc-coated graphene oxide powder, 25-35 pts. wt. epoxy resin, and 8-12 pts. wt. organic solven, placing it in a ball mill, then ball milling for 60 minutes, adding 8-10 pts. wt. curing agent and mixing. USE - The method is useful for preparing zinc-coated graphene oxide composite anti-corrosion coating. ADVANTAGE - The method: utilizes electric brush plating process; can ensure that the zinc-coated graphene oxide powder forms a more uniform and dense stacking layer structure during the coating film formation process; can make full use of the electrochemical protection effect of the zinc layer to improve the corrosion resistance of the coating; can still maintain excellentanti-corrosion effect; reduces the agglomeration and sedimentation phenomenon generated during the use of graphene oxide. DETAILED DESCRIPTION - Preparing zinc-coated graphene oxide composite anti-corrosion coating, comprises (i) preparing graphene oxide-doped zinc coating using the continuous coating device and the brush plating process on the base column, setting the voltage to 10 V constant voltage, when the thickness of the coating reaches the threshold value of 500-1500 µm, the brush plating voltage of the continuous coating device is increased to 15-30V, and the scraper is automatically pressed on the surface of the base cylinder and scraped off the doped coating on the surface of the base cylinder, repeating the generation and scraping operation of the above-mentioned coating layer to obtain solid bulk graphene oxide powder doped zinc composite material, taking out obtained solid block and washing with distilled water and drying, and then placing in a ball mill and grinding into powder to obtain zinc-coated graphene oxide powder, and (ii) mixing 8-15 pts. wt. zinc-coated graphene oxide powder, 25-35 pts. wt. epoxy resin, and 8-12 pts. wt. organic solven, placing it in a ball mill, then ball milling treatment for 60 minutes, and then adding 8-10 pts. wt. curing agent and mixing thoroughly to obtain composite anti-corrosion coating.
