Metal preservative and metal preservative treatment method thereof

The invention discloses a metal preservative and a metal preservative treatment method thereof, and particularly relates to the technical field of metal preservatives, the metal preservative comprises 50 parts of modified epoxy resin, 8-12 parts of a curing agent, 3-5 parts of an auxiliary agent, 4-8 parts of a self-repairing capsule, 10-12 parts of filler and 23-26 parts of ionized water, the curing agent is epoxy amine, the wall material is epoxy amine, and the auxiliary agent is epoxy amine. A core material is a mixture of tung oil, benzotriazole and dilinoleic acid, a metal base material is cleaned and polished firstly, then the metal base material is coated with a layer of primer, then a layer of self-repairing microcapsules is added, after keeping is conducted for 10 min, finally, a coating mixture of the self-repairing microcapsules with the concentration being 6%-8% is sprayed, and a metal base material surface coating is obtained. The self-repairing microcapsule comprises a core material and a wall m
