Abstract

The invention discloses a graphene-modified water-based epoxy zinc-enriched coating as well as a preparation method and application thereof. The graphene-modified water-based epoxy zinc-enriched coating is prepared from water, a curable epoxy resin base material, a zinc powder and large-sized sulfonated graphene. The graphene-modified water-based epoxy zinc-enriched coating provided by the invention is high in flowability and can be stored stably for a long time; furthermore, a coating layer formed by the coating can be firmly combined with a base material and is excellent in corrosion resistance, flexibility, salt fog resistance and impact resistance; particularly, the fog resistance time can be prolonged by 4 times or above; the adhesion force level can reach 0, and the application prospect is wide.

Description

technical field [0001] The invention relates to an epoxy zinc-rich coating and a preparation process thereof, in particular to a water-based epoxy zinc-rich coating modified by sulfonated graphene, a preparation method and application thereof. Background technique [0002] Waterborne epoxy zinc-rich coatings have become a research hotspot of anti-corrosion coatings because of their green and environmental characteristics. In order to make the zinc-rich coating fully and effectively play the role of cathodic protection, it is often necessary to add a large amount of zinc powder (>80wt%) to the coating. Among them, the larger the sheet diameter of the flaky zinc powder, the greater the water resistance of the epoxy zinc-rich coating. The stronger the penetration ability of steam and corrosive medium, the slower the erosion speed of the medium to the coating. However, as the diameter of the zinc powder increases and the particles become coarser, the mechanical properties of...
