▎ 摘  要

NOVELTY - Modified coating comprises 86-94 pts. wt. modified polyurethane acrylate dispersion, 0.6-3.5 pts. wt. graphene oxide, 0.5-1 pts. wt. azobenzene, 4-10 pts. wt. polytetrafluoroethylene, where modified polyurethane acrylate dispersion includes 85-90 pts. wt. polyurethane acrylate dispersion, 3-5 pts. wt. silane coupling agent, and 5-10 pts. wt. inorganic nano powder dispersion, where inorganic nano powder dispersion is a mixed solution of inorganic nano powder and the dispersion, and inorganic nano powder is selected from one or more of nano cerium oxide powder, nano titanium oxide powder, nano silicon oxide powder, and nano tin oxide powder. USE - Modified coating for imitating tiles and wood floors. ADVANTAGE - The modified coating effectively improves the accuracy of inkjet printing images of wooden floors. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a modified coating for imitating tiles and wood floors, which involves: (A) mixing 5-10 pts. wt. inorganic nano powder dispersion, 85-90 pts. wt. polyurethane acrylate dispersion and 3-5 pts. wt. silane coupling agent to obtain modified polyurethane acrylate dispersion; and (B) adding 0.6-3.5 pts. wt. graphene oxide, 0.5-1 pts. wt. azobenzene and 4-10 pts. wt. polytetrafluoroethylene into 86-94 pts. wt. modified polyurethane acrylate dispersion, stirring and reacting for 40-60 minutes, ultrasonic treatment for 20-40 minutes, and obtaining finished modified coating product for imitation ceramic tile and wood floor.
