▎ 摘　　要

NOVELTY - Environmentally friendly and odorless printing ink comprises 32-56 pts. wt. acrylic resin, 16-30 pts. wt. phenolic resin, 12-30 pts. wt. organic solvent, 2-6 pts. wt. calcium carbonate whisker, 1-4 pts. wt. white graphite, 0.6-2.8 pts. wt. nano graphene oxide, 0.6-1.8 pts. wt. nonylphenol polyoxyethyl ether, 0.4-1.2 pts. wt. silicone oil, 0.2-2.4 pts. wt. silane coupling agent, 60-90 pts. wt. water and appropriate amount of pigment. USE - Environmentally friendly and odorless printing ink. ADVANTAGE - The environmentally friendly and odorless printing ink is simple and has broad market prospects. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing environmentally friendly and odorless printing ink, which involves: (A) weighing the nano-graphene oxide and adding it to the sodium hydroxide aqueous solution for ultrasonic dispersion and mixing, then adding sodium lignosulfonate, heating and stirring, and then spray-drying to obtain the pretreated nano-graphene oxide; (B) weighing calcium carbonate whiskers, white graphite, and silicone oil, and adding them to the water for uniform mixing, then adding acrylic resin, phenolic resin, and organic solvent to mix uniformly, and then adding the pretreated nano-graphene oxide under vacuum mixing uniformly to obtain a mixture; and (C) keeping the mixture under the condition of 0.01-0.05MPa for 10-50 minutes, then pressurizing to 30-50MPa and keeping it for 10-50 minutes, and then adding nonylphenol polyoxyethyl ether, silane coupling agent and pigment, and uniformly grinding to obtain the environmentally friendly and odorless printing ink.
