Abstract

The invention discloses a hydroxyl graphene modified coating sealant and a preparation method thereof. The sealant comprises a film forming substance, an anticorrosive additive, a defoaming agent, a leveling agent and deionized water, wherein the anticorrosive additive is a nanoscale hydroxyl graphene aqueous solution of which the mass percentage is 3.5%-4% and the pH value is 8.0-9.5. According to the sealant disclosed by the invention, nanoscale hydroxyl graphene is used as the anticorrosive additive, hydroxyls on hydroxyl graphene can be subjected with a condensation reaction with silica sol serving as the film forming substance and hydroxyls in a silane polymer, so that the performance of a sealing film is remarkably improved; and compared with graphene or redox graphene, the sealing film has higher corrosion resistance and wear resistance.

Description

technical field [0001] The invention belongs to the field of electroplating, in particular to a zinc-nickel alloy and zinc-coated hydroxyl graphene modified sealing agent and a preparation method thereof. Background technique [0002] Graphene is a nano-scale carbon material with special functions such as surface effects, small size effects, quantum size effects, and macroscopic quantum effects, as well as good corrosion resistance, electrical conductivity, and excellent mechanical properties. Since 2004, graphene It has attracted much attention since it was discovered, and this material has great application prospects in many fields. [0003] Zinc plating and zinc-nickel alloys have been widely used as anti-corrosion coatings. In order to improve the corrosion resistance of coatings, sealing treatment is often required after passivation treatment to meet the technical requirements of high-end products in the manufacturing industry. As my country is moving forward from a bi...
