As two-component ambient-cured coatings，Michael addition reaction possess the advantage of mild reaction conditions, high conversion efficiency, high solid content , and low VOC. Plant oil-based polymer resin used in coatings has excellent mechanical properties and pigment wet ability. The reaction conditions of chemical modification on unsaturated fatty acid plant is simple with versatility of molecular design. The purpose of this study is to apply Michael addition reaction curing system to plant oil and prepare novel plant oil-based Michael addition reaction ambient-cured coatings system. These fields have not been researched. The specific goals of this project are included as follows: prepare the plant oil-based acetoacetic acid esterification, amination, acrylic ester prepolymer via thiol-ene coupling and epoxy ring opening reactions, and then prepared for the plant oil-based Michael addition reaction coating films; Systematically study the performance of Michael addition reaction curable coating’s with two-component system composition such as acetyl esterification and amination of vegetable oil, acetyl acetate acetic ester and acrylic ester oils, amination and acrylic ester oils, and the effect of different plant oil base, functional base and containing ring structure to the performance of these coatings; In addition the advantages and disadvantages of Michael addition curing coating system based on plant oil and petrochemical products were compared. This project is to provide systematic research basis and guidance data for the practical application of renewable vegetable oil base with two-component ambient-cured coating film system.
