Synthesis and properties of Acrylic Emulsion with Core-shell Structure in Antifouling Paints

摘要

Water based resins have an important application in environmental benign coating to reduce the volatile organic compounds (VOC). This work describes the synthesis and characterization of an acrylic emulsion with core-shell structure by using pre-emulsion and seed emulsion polymerization technology for antifouling paints. The results indicate that when the ratio of soft and hard monomer is in the range of 1:1～2:1 and the amount of cross-linking agent is added, the comprehensive properties of acrylic emulsion are good. Although the coatings were found to develop a whitish aspect (blushing) due to water retrodiffusion, the films did not break and splint, further research are focused to increase their comprehensive properties for marine antifouling application.
