| description | A hydroxyl graphene-modified plating sealant and a preparation method thereof are disclosed. The plating sealant comprises a film-forming material, a resist, a defoaming agent, a levelling agent, and deionized water; the resist is a nanoscale hydroxyl graphene aqueous solution comprising hydroxyl graphene having a mass fraction of 3.5% to 4% and a pH of 8.0 to 9.5. Nanoscale hydroxyl graphene is used as a resist in the plating sealant of the disclosure, then the hydroxyl groups on hydroxyl graphene can react with the hydroxyl groups of the film-forming material, i.e. silica sol and the silane polymer, by dehydration condensation, thereby significantly improving the performance of the sealing film. The sealing film has higher corrosion resistance and abrasion resistance compared with that prepared by graphene or reduced graphene oxide sealant. |
