Abstract

The invention relates to epoxy resin-graphene-zinc powder anticorrosive coating and a preparation method thereof. The coating comprises a component A capable of forming a film in a curing mode and a component B containing a curing agent, wherein the component A is prepared from 14.64-20.24% of epoxy resin, 0.33-0.56% of graphene, 19.63-37.67% of zinc powder, 23.74-40.37% of filler, 1.41-2.0% of silicon dioxide and the balance a solvent. The component B is prepared from 50% of polyamide and 50% of butanol. Graphene is added into the anticorrosive coating, the anticorrosive effect is improved and the content of the zinc powder is greatly reduced by means of selection of the components, the anticorrosive mode, at the cost of zinc powder, of zinc-rich coating is avoided, zinc oxide fog generated during welding is greatly reduced, and the coating is environmentally friendly. The novel composite coating is good in anti-corrosive effect, free of toxin and pollution and wide in application range.

Description

technical field [0001] The present invention relates to an epoxy resin-graphene-zinc powder anticorrosion coating and a preparation method thereof, specifically, the present invention relates to an epoxy zinc-rich anticorrosion coating based on epoxy resin and containing graphene and a preparation method thereof . Background technique [0002] Corrosion is the phenomenon that metal, concrete, wood and other objects are damaged by the chemical or electrochemical action of the surrounding environment medium. According to relevant statistics, the annual economic loss caused by corrosion in the world is about 700 billion to 1 trillion US dollars, which is about 6 times the sum of economic losses caused by natural disasters such as earthquakes, floods, and typhoons. In my country, the annual loss due to corrosion is about 800 billion yuan, accounting for about 3% of GDP. [0003] The danger of corrosion of steel structures is that it is a kind of uneven damage. The damage occur...
