Polymerizable hydroabietyl acrylate was prepared from the reaction of biomass raw material hydrogenated rosinol with triethylamine,p-hydroxyanisole and acryloyl chloride,and then copolymerized with a series of acrylates and their derivatives to obtain a bio-based fluorocarbon resin with high solid content and low viscosity.The viscosity reduction mechanism of hydroabietyl acrylate was analyzed by molecular dynamics simulation method.And the coating performance of bio-based fluorocarbon resin was further explored.The results indicated that the kinematic viscosity of modified fluorocarbon resin decreased with the increase of the mass fraction of hydroabietyl acrylate.When the mass fraction of hydroabietyl acrylate was 18.6％,the solid content of modified fluorocarbon resin was 78.56％,with its kinematic viscosity equivalent to that of fluorocarbon resin modified by vinyl neodecanoate but far lower than that of modified fluorocarbon resin without large volume side groups.Compared with petroleum resin vinyl neodecanoate,hydroabietyl acrylate exhibited larger space volume,more obvious side group volume effect,lower intermolecular interaction force and lower viscosity.In comparison to that modified by vinyl neodecanoate,fluorocarbon coating modified by hydroabietyl acrylate displayed higher hardness and adhesion,and slightly lower chemical corrosion resistance.
