Abstract

The invention discloses a hydroxyl graphene modified coating sealing agent and a preparation method thereof. The sealing agent includes film-forming substances, resists, defoamers, leveling agents, and deionized water; the resist is The nanoscale hydroxyl graphene aqueous solution with a mass fraction of 3.5% to 4% has a pH value of 8.0 to 9.5. The sealing agent of the present invention uses nano-scale hydroxygraphene as a resist, and the hydroxyl groups on the hydroxygraphene can condense with the hydroxyl groups in the film-forming material silica sol and silane polymer, thereby significantly improving the performance of the sealing film. Compared with ene 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...
