▎ 摘　　要

NOVELTY - A water-resistant glass printing ink contains 10-20 pts. wt. aqueous polyurethane resin, 15-25 pts. wt. modified water-based acrylic resin, 15-20 pts. wt. nano-alumina, 5-10 pts. wt. dimethicone, 5-15 pts. wt. colorant, 1-5 pts. wt. chitosan-graphene composite material, 1-5 pts. wt. additive and 1-2 pts. wt. walnut shell powder. USE - Water-resistant glass printing ink (claimed). ADVANTAGE - The glass printing ink has excellent water resistance, mutual capacitance and adhesion property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of glass printing ink, which involves uniformly mixing nano-alumina and colorant, adding aqueous polyurethane resin and modified water-based acrylic resin to mixture under stirring, uniformly mixing, dispersing, grinding, adding chitosan-graphene composite material to mixture, ultrasonically dispersing for 30-40 minutes, adding remaining raw materials to mixture and uniformly stirring.
