Description

technical field [0001] The invention belongs to the technical field of heavy-duty anti-corrosion coatings, in particular to a graphene / epoxy zinc powder heavy-duty anti-corrosion coating and a preparation method thereof. Background technique [0002] Metal corrosion is the destruction of metals by chemical or electrochemical reactions. Corrosion of metals in industrial equipment such as petrochemicals, equipment and other infrastructure can cause catastrophic damage. Epoxy zinc-rich coating is a heavy-duty anti-corrosion coating with excellent corrosion resistance, which is widely used in marine equipment, transportation, coastal steel structures and other fields. The anti-corrosion mechanism of epoxy zinc-rich coatings is mainly the electrochemical protection of zinc. Generally, when zinc-rich coatings play the role of cathodic protection, the dry film must contain a large amount of zinc powder particles, which is enough to make the gap between zinc powder And the degree ...
