Abstract

The invention relates to a graphene epoxy anticorrosive paint, which comprises a component A and a component B, wherein the component A contains the following raw materials in parts by mass: 35 partsof epoxy resin, 0.5-2 parts of graphite raw materials, 1-3 parts of dispersing agent and 8-10 parts of first mixed solvent; the component A contains the following raw materials in parts by mass: 30 parts of second mixed solvent and 70 parts of curing agent. The functionalization of graphene and dispersion thereof in epoxy resin can be synchronously integrated by utilizing a ball grinding manner, so that the problem of dispersity of graphene can be solved, and the obtaining of the graphene epoxy anticorrosive paint with strong storage stability and good comprehensive performances can be facilitated, in addition, the production technology flow of graphene products can be decreased, and the industrial production cost can be lowered.

Description

technical field [0001] The invention relates to a graphene epoxy anticorrosion coating and a preparation method thereof, belonging to the technical field of anticorrosion coatings. Background technique [0002] Heavy-duty anti-corrosion coatings usually refer to anti-corrosion coatings that are used in harsh environments and have a corrosion protection period of more than ten years. Compared with conventional anti-corrosion coatings, heavy-duty anti-corrosion coatings have longer anti-corrosion protection timeliness, and generally have a service life of more than ten years under harsh conditions such as chemical and marine environments, so they are widely used in engineering fields where corrosion problems are prominent and short-term maintenance is not convenient , such as high-end equipment, large steel structures, petrochemical power, pipeline anticorrosion, etc. As a coating variety with great development potential in the coatings industry, it has the characteristics of...
