Preparation and characterization of novel waterborne antifouling coating

摘要

In this article, a waterborne antifouling coating was prepared using novel synthesized sili-cone-acrylate emulsion and 2,3-epoxy-2-methyl-l,4-naphthoquinone. The silicone-acrylate emulsion was synthesized using polymerizable co-emulsifiers (4-pro-pyl-l-(l-propenyl) sulfosuccinate (M-10S) and allyl octylphenyl polyoxyethylene glycol ether (AE-200)), and characterized by Fourier transform infrared spectroscopy, differential scanning calorimetry, and transmission electron microscopy micrograph. The particles in the emulsion are all spherical with an average particle size of 66.5 nm. The adhesion of the coating film reaches 1 grade and its impact resistance is over 50 cm kg. The antifouling activity of the coating film is excellent when the concentration of ME is 6.77 wt%.
