Abstract: Disclosed are methods for manufacturing bio-based epoxy resins. The raw materials of the resins include lignin, polyol, solvent, catalyst, acid anhydride, and multi-epoxy compound. The methods of manufacturing the resins include evenly mixing the lignin, the polyol, the catalyst, and the solvent together to form a mixture. The acid anhydride is added to the mixture to process esterification for forming an intermediate product. The multi-epoxy compound is added to the intermediate product to process epoxidation for forming the bio-based epoxy resins. The bio-based epoxy resin has excellent compatibility with the solvent, such that the solvent can be added to the bio-based epoxy resins to form coatings having a tunable solid content. As a result, the coating can be applied to the surfaces of every type of base material.
