▎ 摘  要

NOVELTY - Environmentally-friendly and wear-resistant aqueous ink comprises 40-60 pts. wt. aqueous polyurethane acrylate emulsion with solid content of 35-45%, 15-25 pts. wt. nano-silicon dioxide suspension with solid content of 20-28%, 10-20 pts. wt. bisphenol A epoxy resin, 1-5 pts. wt. wear-resistant calcium carbonate modifier, 1-5 pts. wt. alpha -methyl glucoside, 1-5 pts. wt. polyethylene oxide, 1-5 pts. wt. ethyl lactate, 1-2 pts. wt. butyl acetate, 1-2 pts. wt. sorbitan oleate, 15-25 pts. wt. polyethylene glycol 1450, 1-2 pts. wt. emulsified silicone oil, 5-12 pts. wt. ethanol, 1-2 pts. wt. anti-freezing agent, 1-2 pts. wt. antifoaming agent, 1-2 pts. wt. antibacterial agent, 1-2 pts. wt. flatting agent, 10-16 pts. wt. pigments and 30-60 pts. wt. water. USE - The ink is useful for packing box printing. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation the aqueous ink, comprising (a) dispersing the wear-resistant calcium carbonate modifier in water at 80-90 degrees C, stirring at a speed of 1000-2000 revolutions/minute for 10-20 minutes, reducing the speed to 100-200 revolutions/minute, adding aqueous polyurethane acrylate emulsion, nano-silicon dioxide suspension, and bisphenol A epoxy resin, stirring for 5-15 minutes, adding alpha -methyl glucoside, polyethylene oxide, ethyl lactate, butyl acetate, sorbitan oleate, polyethylene glycol 1450, emulsified silicone oil, ethanol, pigment, anti-freezing agent, antifoaming agent, antibacterial agent, flatting agent, continuously stirring for 20-40 minutes, and adding into a grinder to grind until the particle size of the obtained slurry is less than or equal to 10 mu m.
