Abstract:Epoxy acrylate emulsion modified by organic fluorine was prepared by making use of core-shell emulsion polymerization method.The effects of mass ratio of soft and hard monomers, dosage of fluorine monomer,and dosage of epoxy resin on the properties of as-prepared emulsion were investigated.The optimized formulation for preparing the emulsion was established, and the marine anti-fouling performance of the paint made of the emulsion was primarily evaluated.Results indicate that the emulsion prepared at a mass ratio of soft and hard monomers of 1:1, acrylate dosage of 2%,monomer core-shell mass ratio of 2:3, core glass transition temperature of-10℃,organic fluorine monomer dosage of 8%(in relation to the total content of monomers), and epoxy resin dosage of 9%(in relation to the total content of monomers) possesses the optimal properties.The paint made of the emulsion possessing the optimal properties had a adhesion force of grade 2,water contact angle of 114.0°,anti-impact force of over 500 N·cm,and water absorption rate of 2.41%,showing desired anti-fouling performance in marine environment.
Keywords:core-shell emulsion polymerization  fluorine modified epoxy acrylic acid  adhesion force  contact angle  anti-impact force  water absorption rate
