NOVELTY - Composite conductive ultra violet curing ink comprises 40-50 wt.% micron-sized silver powder, 1-10 wt.% nano-silver powder, 9-15 wt.% ultra-high conductivity electronic grade graphene powder and 25-50 wt.% organic carrier. USE - The composite conductive ultra violet curing ink is useful in printing of radio frequency identification tag antennas (claimed) and for screen printing to obtain a film with a strictly controllable geometric shape and thickness. ADVANTAGE - The ink: can reduce used amount of silver; avoids agglomeration; has high oxidation and bending resistance, faster curing and better flexibility and sensitivity; and is stable and more viscous. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing composite conductive ultra violet curing ink, comprising (i) taking ultra-high conductivity electronic grade graphene, dispersant and zirconium oxide balls respectively and placing the ultra-high conductivity electronic grade graphene and zirconium oxide balls in the zirconium oxide ball milling tank; (ii) sealing the zirconium oxide ball mill, placing it in the planetary ball mill, ball milling at 800 revolutions/minute for 10-20 hours and collecting the product to obtain a black powder; (iii) adding the dispersant and the black powder into the autoclave together at 55 degrees C, pumping in carbon dioxide gas after the pressure in the kettle reaches 15MPa beginning the carbon dioxide to circulate; (iv) opening the valve to quickly relieve the pressure after 30 minutes, so that the air pressure in the autoclave quickly drops to normal pressure; (v) repeating steps (iii) and (iv) for 3 times to obtain a mixture; (vi) dissolving the mixture obtained in mixed solution of 2-propanol, 1-butanol and 1-methyl-2-propanol, soaking for two weeks until the mixed solvent completely dissolves the dispersant, stirring for 2 hours, and dispersing ultrasonically for 15-30 minutes to obtain stock solution 1; (vii) taking a certain amount of the stock solution 1, placing it in a beaker and adding a quick-drying solvent while stirring to prepare a stock solution 2; (viii) taking a certain amount of the stock solution 2, pouring it into a transparent pressure-resistant glass container, passing in dimethyl ether gas and freeze-drying the collected product for 4-6 days at -50 degrees C to obtain a dried graphene dispersion; (ix) taking HAPBI-3 and the graphene dispersion, adding into dihydroglucose ketone and performing ultrasonic dispersion while stirring at high speed for 30-45 minutes to get stock solution 3; (x) taking micron-level silver powder and nano-level silver powder, adding into the stock solution 3, placing it into the vacuum stirrer, stirring at 1000-2000 revolutions/minute for 2-3 hours, adding resin and additives and stirring continuously for 30 minutes to obtain a silver-black paste product; (xi) adding the silver-black paste product obtained into a zirconium oxide ball mill tank and placing it into a planetary ball mill and ball milling at 100-300 revolutions/minute for 8-15 hours; and (xii) taking out the mixture and grinding it more than 3 times with a three-roll mill to make it fully mixed to form a uniform slurry.
