▎ 摘  要

NOVELTY - Preparation of graphene conductive paste with high temperature adhesive performance comprises magnetic stirring of 1-5 wt.% defoaming agent and 1-5 wt.% thickening agent at 60-80 degrees C, and dissolving in terpineol; magnetic stirring at 60-80 degrees C, adding 1-2 wt.% dispersant, 1-3 wt.% leveling agent and 1-2 wt.% plasticizer, stirring for 12-24 hours, and obtaining conductive paste of organic carrier phase; weighing organic carrier, setting in vacuum stirring kettle, stirring at 200-500 revolutions/minute (rpm), adding mixed graphite powder and low-melting point glass powder, and mixing graphene, organic carrier and glass powder at ratio of 40-65:25-55:5-10; mixing primary precursor at 120-160 degrees C, heating for 1-2 hours, and carrying out curing treatment of precursor; and curing precursor into vacuum degree, and vacuum stirring to 500-1500 rpm for 24-72 hours. USE - Method for preparing graphene conductive paste with high temperature adhesive performance. ADVANTAGE - The paste has excellent bonding force and electrical conductivity.
