NOVELTY - Modified graphene heat printing ink comprises 30-50 wt.% printing ink resin, 5-12 wt.% modified graphene, 20-35 wt.% conductive nano-silver, and 10-25 wt.% nano-chromium. Preparation of modified graphene heat printing ink comprises taking printing ink resin, adding remaining raw materials, and reacting. USE - Modified graphene heat printing ink. ADVANTAGE - The ink is water-resistant, oil-resistant, alkali-resistant, acid-resistant, and has long useful life and high transmission rate.
