NOVELTY - A free alcohol of graphene oxide comprises lubricating liquid containing 5-8 pts. wt. glycerin, 0.1-0.2 pt. wt. liquid graphene oxide, 30-40 pts. wt. magnetic activated water, 14-18 pts. wt. gum Arabic, 3-4 pts. wt. dibasic sodium phosphate, 2-3 pts. wt. xylose, 0.2-0.3 pt. wt. polyether modified silicone oil, acidic buffer liquid, and 1-2 pts. wt. fatty alcohol polyoxyethylene ether. USE - A free alcohol of graphene oxide. ADVANTAGE - Water-ink balance, printing quality and efficiency are improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation of free alcohol of graphene oxide which involves carrying out magnetic activated water heating at 50-60 degrees C, adding dibasic sodium phosphate and xylose, stirring, adding gum Arabic, continuously stirring until glue stuff is dissolved, adding other residual materials except acid buffer liquid, stirring and mixing for 50-60 minutes, adding acidic buffer solution, and adjusting pH to 4.5-5.5.
