Abstract

The invention discloses anticorrosive paint containing graphene oxide scales, and a preparation method thereof. The anticorrosive paint comprises pre-accelerated vinyl ester resin, graphene oxide scale dispersion liquid and a curing agent, wherein the graphene oxide scale dispersion liquid accounts for 0.8-2% by weight of the pre-accelerated vinyl ester resin, and the curing agent accounts for 1-3% by weight of the pre-accelerated vinyl ester resin and the graphene oxide scale dispersion liquid. The pre-accelerated vinyl ester resin comprises 90-100 parts of vinyl ester resin and 0.2-2 parts of accelerants, and the graphene oxide scale dispersion liquid comprises 60-100 parts of the graphene oxide scales and 100 parts of dispersants. Through a certain amount of the graphene oxide scales serving as functional fillers, resin serving as a film forming agent, and added assistants, the anticorrosive paint has the advantages of regulated viscosity and rheological properties, improved mechanical property and construction property, enhanced temperature and corrosion resistance, ultra-thinness, wear resistance, toughness, improved comprehensive physical and chemical properties, and the like.

Description

technical field [0001] The invention relates to the technical field of production of polymer materials, composite materials, high temperature resistance, anti-corrosion, and conductive vinyl ester resin coatings, in particular to a graphene oxide flake anti-corrosion coating and a preparation method thereof. Background technique [0002] Anti-corrosion coatings are the most widely used coatings in modern industry, energy, marine and other fields. They can prevent substrate corrosion through the coating's shielding, corrosion inhibition and cathodic protection functions, thereby prolonging the service life of the protected body. [0003] Vinyl ester resin glass flake (glass flake thickness 3-5μm) coating is a new type of high-efficiency anti-corrosion coating. Due to the addition of flaky glass flakes in the coating, the flaky glass flakes are arranged parallel to each other or overlapped in the coating. Fish scales, like layers of armor, form a dense, labyrinth-structure imp...
