▎ 摘　　要

NOVELTY - The graphene has auxiliary agent e.g. antifoaming agent, and sheet-shaped silver powder provided with 39-48 wt. % diameter. Particle size of spherical silver powder is ranged with 14-23 wt. %. Inorganic conductive additive is ranged with 0.5-1 wt. %. Organic carrier is ranged with 24-32 wt. %. The inorganic conductive additive is selected from grain is ranged with 50nm to 5 mu, where the graphene is 50nm to 5 mu. An organic resin is selected from modified polyimide, unsaturated polyester, polyacrylic ester and vinyl chloride-acetate copolymer. USE - Graphene for touch screen silver paste. ADVANTAGE - The graphene has good adhesion function, long time high temperature and high humidity aging test and cold-hot impact, bending property, good weather resistance property, good stability, conductivity and insulating oil. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene preparation method for touch screen silver paste.
