▎ 摘　　要

NOVELTY - A prism resin comprises 20-70 pts. wt. polybutadiene acrylate, 3-30 pts. wt. tackifying resin, 30-60 pts. wt. active diluent, 0.5-10 pts. wt. graphene oxide-modified nano-zirconium oxide, 1-20 pts. wt. photoinitiator, and 0.5-5 pts. wt. thermal initiator. USE - Prism resin for laminated film. ADVANTAGE - The prism resin has high refractive index, and high brightness, and is prepared by simple method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of prism resin, which involves (1) mixing polybutadiene acrylate and graphene oxide-modified nano-zirconium oxide uniformly, adding thermal initiator, mixing for 1-2 hours under the condition of nitrogen, and controlling the temperature at 60-80degreesC to obtain prepolymer, and (2) mixing the prepolymer obtained in the step (1) with tackifying resin, active diluent, and photoinitiator uniformly for 0.5-2 hours under the condition of nitrogen, and controlling the temperature at 40-50degrees Celsius to obtain a final product.
