Abstract

An environment-friendly graphene-based aqueous antifouling paint adopts a two-component design, wherein a component A is composed of a water-based resin emulsion, an antifouling agent / graphene compound, zinc oxide, rosin, a filler, an auxiliary agent and the like, and a component B is a water-based polyamine curing agent; the component A and the component B are blended according to a certain proportion during construction. The antifouling paint has excellent antifouling performance, and the antifouling agent is loaded on the surface of the graphene through chemical bonding, so that the purposeof controlled release of the antifouling agent is achieved. The aqueous antifouling paint has antifouling validity period of 12 months on Xiamen sea area shallow sea hanging plate, has the antifouling validity period of 1-2 years in the actual application process, and has wide application prospects.

Description

technical field [0001] The invention relates to the technical field of chemical materials, in particular to an environment-friendly graphene-based water-based antifouling paint and a preparation method thereof. Background technique [0002] Antifouling coatings are coatings applied on the surface of marine equipment and facilities such as ships, marine engineering and docks. They are mainly used to prevent the adhesion of fouling organisms such as barnacles, mussels and algae. Polishing type and fouling release type etc. Among them, abrasive and self-polishing antifouling coatings mainly rely on the release of antifouling agents inside the coating to achieve the purpose of inhibiting fouling organisms. Therefore, the long-term, effective and stable antifouling agent control technology is one of the key technologies for the development of long-term antifouling paint. [0003] Graphene is a two-dimensional carbon nanomaterial composed of carbon atoms in a hexagonal honeycomb...
