Abstract

The invention discloses a graphene anticorrosive coating. The graphene anticorrosive coating comprises the following components by weight percent: 0.01-7% of graphene, 35-45% of methyl-silicone, 10-15% of epoxy resin with the solid content of 50%, 5-20% of a preservative, 3-6% of an assistant, 1-3% of a silane coupling agent and the balance of a base material serving as a solvent. The invention further discloses a preparation method of the graphene anticorrosive coating and a method for coating a wind power spindle by using the graphene anticorrosive coating. The graphene anticorrosive coatinguses the fact that two-dimensional carbon nanosheet structures of graphene of thermally reduced graphene are stacked layer by layer to form a dense physical anticorrosive insulating layer; the silanecoupling agent modifying technique of the thermally reduced graphene is studied, the silane hydrolysis hydroxyl and an oxygen-containing group on the surface of the thermally reduced graphene form achemical bond, the silane amino directly participates into the curing of the epoxy resin, a dense anticorrosive film is formed through overlap joint; the synergistic activation of the graphene and a zinc powder is studied to form a conductive path protected by a metal base cathode, the excellent electrochemical protection is realized, the multi-anticorrosion technique facing the wind power spindlein the severe marine service environment is formed; the reverse thinking is adopted to change corrosion prevention into leading.

Description

technical field [0001] The invention relates to graphene anticorrosion coatings. Background technique [0002] Large-scale wind power main shafts, especially offshore large-scale wind power main shafts, have high anti-corrosion requirements. It is generally expected that the service life of wind power main shafts can reach 20 years. However, the current anti-corrosion measures for wind power main shafts are not high in anti-corrosion performance, and it is difficult to achieve 20 years. The amount of zinc used in the current anti-corrosion method High cost, high cost, serious zinc fog pollution on the work site, and poor working environment for workers. The patent application publication number is CN107192327A: a wheel gauge for coating and the high anti-corrosion coating process of the wind power main shaft using the wheel gauge, which is realized by changing the mechanical structure of the coating; the patent authorization announcement number is CN 102775877B: Western wind...
