Embodiment 1

[0018] The static electricity heating slurry that a kind of graphene carbon nanotube is made comprises (mass part): 5 parts of few-layer graphene, 2 parts of carbon nanotubes, 1 part of carbon black, 30 parts of film-forming substances, 60 parts of solvent, 1 part 1 part acidic reagent, 1 part dispersant.

[0019] The preparation method of static electricity heating slurry is as follows: weigh the required amount of few-layer graphene, carbon nanotubes, and carbon black according to the proportion, add solvent, acidic reagent, film-forming substance, and dispersant to form a mixed solution, and mechanically disperse for a period of time. Wait until the mixed solution does not separate, and disperse at high speed for two hours to obtain a heat-generating slurry that absorbs static electricity.

Abstract

The invention relates to a preparation method of an electrostatic absorption heating slurry prepared from a graphene carbon nano tube. The electrostatic absorption heating slurry comprises 3-10 partsof graphene, 1-5 parts of carbon nano tube and 0.5-2 parts of carbon black according to mass percentage; and the resistance of a film surface is less than 107 Omega / sq. The preparation method of the electrostatic absorption heating slurry prepared from the graphene carbon nano tube, provided by the invention, has the advantages that the content of the graphene is reduced, and the production cost is reduced because the graphene, the carbon nano tube and the carbon black are used in a coordinated manner; moreover, by adjusting the mixing ratio of the graphene, the carbon nano tube and the carbonblack to an appropriate mixing ratio, the anti-static electricity performance of a heating film is enhanced, and the content of the graphene can also be reduced.

Description

technical field [0001] The invention relates to a preparation method of a static electricity absorption and heating slurry made of graphene carbon nanotubes, and relates to the field of graphene. Background technique [0002] The heating film is a planar heating element composed of an electrical insulating material and a heating resistance material packaged in it. With the rapid progress of society, all walks of life and people's daily life have put forward higher requirements for electric heating materials. Although traditional electric heating materials such as metal resistance wires have a fast heating speed and high heat dissipation temperature, it is difficult to automatically control the temperature to achieve constant temperature heating. Although the ceramic PTC material has strong temperature control, its application range is greatly limited by its shortcomings such as complex processing technology, difficult processing and molding, high room temperature resistivity...
