Abstract

The invention discloses a graphene oxide base conductive slurry composition for intaglio printing. The graphene oxide base conductive slurry composition is prepared from, by weight, 55%-97.9% of composite conductive particle, 1%-20% of graphene, 1%-20% of carbon nanotube, 0.1%-5% of indium tin oxide, 0-10% of epoxy diluent, 0-5% of adhesive resin and 0-10% of phthalic anhydride. The prepared high-thermal-conductivity graphene conducting resin cannot reduce the electrical conductivity while greatly improving the heat-conducting property of the conducting resin, thereby solving the technical problem of concurrence of high electrical conductivity, excellent mechanical strength and heat-conducting property of the conducting resin; the environmental protection is ensured while the efficiency reaches or even exceeds the level of an existing commercial slurry; and the graphene oxide base conductive slurry composition is suitable for the intaglio printing.

Description

technical field [0001] The invention relates to a graphene oxide-based conductive paste composition, in particular to a graphene oxide-based conductive paste composition for gravure printing and a preparation method thereof. Background technique [0002] With the development of electronic industrialization, electronic components are developing towards intensive and high performance. More and more manufacturers hope to make electronic products thinner and lighter. This has formed the trend of lightweight, thin and miniaturized products. This trend puts forward higher requirements for the heat dissipation of electronic products. [0003] Conductive paste is an adhesive with certain electrical and thermal conductivity after curing. It is usually composed of matrix resin, conductive filler and additives. The resin matrix mainly plays a bonding role; the filler is used to form a conductive path. The matrix resin is mainly thermosetting epoxy resin, silicone resin, polyimide r...
