NOVELTY - A kind of coating and coating method thereof, described coating comprises the binder of 35~40wt%, the graphene of 0.1~0.5wt%, the nano-zinc of 0.05~0.3wt%, 35~40wt% % metal powder, and 6~10wt% filler. The coating method of the paint comprises a stirring step of stirring the paint for 5 to 10 minutes, a filtering step of filtering the paint, and a coating of the paint to a target workpiece with a centrifugal coating device Steps, a sintering step of sintering the target workpiece at a temperature of 280-340° C. for 30-40 minutes, and a cooling step of cooling the target workpiece to room temperature. After the target workpiece is coated with the coating, the metal powder is used as a sacrificial anode, and the properties of the nano-zinc and the graphene are used to make the nano-zinc and the graphene together form a good barrier effect. protection mechanism.
