NOVELTY - Printing aqueous ink material comprises carbon nanotube modified polyurethane emulsion, polyurethane emulsion with amino and carboxy groups, soybean oil, carnauba wax emulsion, modified graphene, negative ion powder, ethylene glycol, cellulose acetate butyrate and colorant. USE - Used as printing aqueous ink material. ADVANTAGE - The printing aqueous ink material: is environmentally friendly, simple to prepare and use, and suitable for large scale industrial production. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: Preparing the printing aqueous ink material comprising mixing carbon nanotube modified polyurethane emulsion, polyurethane emulsion with amino and carboxy groups, soybean oil, carnauba wax emulsion, modified graphene, negative ion powder, ethylene glycol, cellulose acetate butyrate and colorant. Use method of printing aqueous ink material comprising (1) selecting suitable paper or plastic, cleaning the surface first, applying anti-seepage material on the front and/or back of the paper or plastic respectively, adding it in an oven at 35-45°C to dry, forming a film on the front and/or back of the paper or plastic, film formed by the anti-seepage material prevents the penetration of ink between the front and back of paper or plastic; and (2) coating a printing aqueous ink material on the front and/or back side of the product obtained in step (1) respectively, aqueous ink materials on front and back can be same or different, and then placing in an oven at 60-90°C to dry to complete the ink printing work.
