ZINC-RICH EPOXY ANTI-CORROSION COATING AND PREPARATION METHOD THEREOF

摘要

A zinc-rich epoxy anti-corrosion coating, including a component A, capable of being cured into a film, and a component B containing a curing agent; component A contains, by weight percentage, graphene (0.1-5wt%), zinc powder (0-35wt%), filler (30-70wt%), 10-20wt% epoxy resin having 54wt% solids content, and solvent (10-20wt%), wherein the sum of the weight percentages of the graphene, zinc powder and filler is 60-80wt% and the sum of the weight percentages of all components of compenent A is 100wt%. The present invention adds graphene into an anti-corrosion coating, thus decreasing the thickness of the coating film, increases the anti-corrosion effect while decreasing zinc powder contents, reduces the amount of zinc oxide vapor generated during welding, and is environmentally friendly.
