Abstract

The invention provides a high-performance anticorrosive coating with graphene and a preparation method thereof. The high-performance anticorrosive coating with the graphene is prepared from a component A and a component B, wherein the component A is prepared from the following ingredients in parts by weight: 20 to 35 parts of furan resin, 2 to 5 parts of the graphene, 1 to 2 parts of phosphate solution, 0.5 to 1 part of antioxidant, 3 to 8 parts of adhesion promoter, 0.3 to 0.8 part of dispersant, 8 to 15 parts of emulsifier, 40 to 70 parts of filler and 15 to 30 parts of solvent; the component B is prepared from the following ingredients in parts by weight: 10 to 18 parts of sulfonic acid curing agent and 11 to 15 parts of methanol aqueous solution; a weight ratio of the component A to the component B is (4 to 4.5) to 1. The coating provided by the invention is used for solving the problems that a common anticorrosive coating with the furan resin is poor in oxidation-resistant performance and the graphene is easily agglomerated in the coating; the performance of the corrosion prevention, the oxidation resistance, the high temperature resistance and the like of the coating is improved and the coating has excellent comprehensive performance, is wide in scope of application and can be used for a high-temperature and high-corrosion environment.

Description

technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to a graphene high-performance anti-corrosion coating and a preparation method thereof. Background technique [0002] Graphene is a single layer of carbon atoms tightly packed into a two-dimensional hexagonal honeycomb lattice structure, with sp 2 connected in a hybrid manner. Microscopically, the single-layer graphene film is not a two-dimensional flat structure, but has a "nanoscale" stable microwave-like single-layer structure, which is the only two-dimensional free-state atomic crystal found so far; macroscopically, graphite Alkenes can be warped into zero-dimensional fullerenes, rolled into one-dimensional carbon nanotubes or stacked into three-dimensional graphite. The existence of stable carbon six-membered rings in graphene's unique two-dimensional periodic honeycomb lattice structure endows it with excellent performance: the thickness of single-layer graph...
