“…The water-based acrylic resin prepared in this study has neither the hydrolyzable structure formed by grafting hydrolyzable acrylic acid, small molecular organic acid and metal ions, nor the copolymerization of hydrolyzable silane ester monomers, 42 but it still has good selfpolishing properties. It is because the water-based acrylate resin contains water-based structural units (carboxyl group, carboxyl anion and amide group), which improves the water solubility of the resin, and can make the coating surface slowly dissolve and release under the scouring of seawater at a certain speed.…”

In order to reduce the release of volatile organic compounds (VOCs), it is of great practical significance to develop water‐based self‐polishing antifouling coatings instead of traditional acrylic self‐polishing antifouling coatings. However, when preparing film forming matrix resin emulsions for water‐based antifouling coatings, the use of emulsifiers in large amounts causes film‐forming defects and poor adhesion. Herein, soap‐free emulsion polymerization is utilized to prepare resin emulsions by copolymerization of hydrophilic monomers, lipophilic monomers and polymerizable hydrophilic ionic monomers. The hydrophilic structure can give the water‐based polymer self‐emulsification function to maintain the stability of the emulsion and can promote the fusion between the latex particles by forming hydrogen bonds and coordination bonds, and its connection with the pigments and fillers in the coating can also promote the excellent film formation of the coating. The experimental results show that the water‐based self‐polishing antifouling resin emulsion has good storage stability and compatibility with the pigments and fillers. The coatings formulated using this emulsion as the film‐forming matrix firmly adhered to substrates and displayed satisfactory antifouling performance even after being exposed to a real sea environment for 18 months. This study presents a simple approach for the development of water‐based resin emulsion with good storage stability and good water‐based self‐polishing marine antifouling coatings.
