Abstract

The invention discloses a graphene conductive coating and a preparation method thereof. The graphene conductive coating is prepared from the following components in parts by weight: 15 to 30 parts ofgraphene, 5 to 20 parts of carbon nano pipes, 2 to 10 parts of conductive carbon black, 10 to 30 parts of matrix resin, 2 to 5 parts of dispersing agents, 2 to 5 parts of binding agents, 2 to 5 partsof adhesion promoters, 1 to 5 parts of flatting agents, 0.5 to 1.0 part of a photoinitiator and 30 to 50 parts of organic solvents. According to the graphene conductive coating and the preparation method thereof, the graphene and the carbon nano pipes firstly form a graphene / carbon nano pipe composite material, the graphene and the carbon nano pipes can be mixed to be evener under the effect of critical fluid, the Van Der Waals' force among layers of the graphene is damaged through pressure released instantaneously, and thus the graphene is not easy to agglomerate.

Description

technical field [0001] The invention belongs to the technical field of conductive paint, in particular to a graphene conductive paint and a preparation method thereof. Background technique [0002] Conductive coatings have been developed for about half a century. It is a functional coating that has developed rapidly with modern science and technology. At present, conductive coatings play an important role in various military and civilian industrial fields such as electronics, electrical appliances, aviation, and printing. [0003] Conductive coatings can be traced back to the patent of conductive adhesive made of silver and epoxy resin in the United States in 1948, and then in the 1950s, my country also began to enter the field of conductive coatings. The most commonly used conductive fillers in coatings are graphite fillers, metal fillers, metal oxide fillers, etc. Since the advent of graphene in 2004, this "miracle material" has attracted great interest from the global s...
