▎ 摘 要
NOVELTY - Graphene nano silver electronic paste comprises 30-70 pts. wt. metal conductive powder, 4-10 pts. wt. graphene nano silver dispersion, 18-50 pts. wt. organic solvent, 5-15 pts. wt. resin and 0.1-3 pts. wt. additives. USE - The paste is useful for touch screen field (claimed). ADVANTAGE - The method is simple and economical and has social benefits and suitable for industrial production. The product has strong adaptability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene nano silver electronic paste, comprising (i) adding graphene, nano silver, dispersion and silane coupling agent into the organic solvent and carrying out ultrasonic heat treatment at 50-80 degrees C to obtain graphene nano silver dispersion; and (ii) adding the resin into the organic solvent, heating at 60-85 degrees C, insulating, dissolving, adding graphene nano-silver dispersion, metal conductive powder, high-speed stirring additive, milling in three-roll mill by roll bar and filtering.
