The invention discloses a photocurable resin based on epoxy vegetable oil and gallic acid, and a preparation method and application thereof. The method firstly utilizes gallic acid and acrylic anhydride compound to react to obtain a gallic acid triacrylate/acrylic compound mixed intermediate; and then utilizes epoxy vegetable oil and the obtained mixed intermediate to carry out an epoxy ring-opening reaction to obtain a novel bio-based ring Oxyacrylate prepolymer; finally, diluting monomer, photoinitiator, polymerization inhibitor, etc. are added to disperse evenly to obtain bio-based photocurable resin. The obtained resin has the advantages of low viscosity, fast curing speed and the like, and has excellent material mechanical and thermodynamic properties after curing. Therefore, it can be used as matrix resin applications such as photocurable 3D printing materials, coatings and inks. The process of the invention is simple and environmentally friendly, and most of the raw materials come from renewable resources, so it has great significance for promoting the sustainable development of the photocurable material. |
