Polyfunctional castor oil-based photo-cured resin as well as preparation method and application thereof

The invention relates to a polyfunctional castor oil-based photo-cured resin as well as a preparation method and application thereof. The preparation method comprises the following steps: with isocyanate and hydroxyl acrylate as raw materials, adding a polymerization inhibitor and a catalyst, introducing nitrogen for protection, and reacting for a certain period of time, so as to obtain an intermediate isocyanate semi-blocked prepolymer; adding castor oil into the prepared isocyanate semi-blocked prepolymer, so as to obtain castor oil-based urethane acrylate resin; and mixing the castor oil-based urethane acrylate resin with a photoinitiator and a diluent, and carrying out ultraviolet light radiation, so as to obtain UV castor oil-based resin with excellent performance. The photo-cured resin synthesized by virtue of the preparation method has relatively high molecular weight and viscosity, so that the interaction among resin molecules is enhanced, and the photo-crosslinking reaction efficiency of the resin is improved; the photo-cured resin contains more terminal double bonds, can be rapidly photo-cured and is suitable for being used as UV cured coatings, 3D printing materials and the like; and the prepared photo-cured resin has the beneficial effects that the water absorption rate and volume shrinkage rate of a cured film are substantially increased, meanwhile, the cost is low, the process is simple and controllable, and a product is relatively environment-friendly.
