▎ 摘　　要

NOVELTY - Graphene radio frequency identification (RFID) electronic label for intaglio printing method preparation comprises a base material, and a graphene conductive paste printed on the base material by a gravure printing method. The graphene conductive paste includes 5-10 pts. wt. graphene, 1-3 pts. wt. surfactant, 5-10 pts. wt. dispersant, and 15-25 pts. wt. cured resin. The cured resin is o-cresol novolac epoxy resin, polyurethane, methyltetrahydrophthalic anhydride, trimethylolpropane, and toluene-2,4-diisocyanate in a mass ratio of (70-90):(10-30):(18-23):(1.8-5.5):(0.5-1.6). The surfactant includes sodium dodecylbenzenesulfonate, and sodium aliphatic alcohol polyoxyethylene ether sulfate in a mass ratio of (0.5-0.8):(1.2-1.5). USE - Used as graphene RFID electronic label for intaglio printing method preparation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the graphene RFID electronic label, comprising (1) stirring o-cresol novolac epoxy resin, polyurethane, methyltetrahydrophthalic anhydride, and trimethylolpropane at 50degreesC for 1 hour, adding toluene 2,4-diisocyanate and continuing stirring for 1 hour to obtain a cured resin slurry, turning on ultrasonic dispersion and magnetic stirring on at the same time, adding surfactant, dispersant and auxiliary agent to the cured resin slurry and uniformly mixing, adding graphene, and continuing ultrasonic dispersion and magnetic stirring for 4 hours to obtain graphene conductive paste, (2) attaching the graphene conductive paste in the ink tank at 60-90degrees Celsius to the gravure tank of the gravure roll, scraping off the excess conductive ink with a scrapping blade, and then transferring to the substrate through rolling between the gravure roller and the embossing roller to obtain a printed substrate, and (3) curing the printed substrate at high temperature, subjecting to secondary calendering on a roller to obtain the graphene RFID electronic label.
