Flame-retardant graphene conducting material and preparation method thereof

Abstract

The invention discloses a flame-retardant graphene conducting material. The flame-retardant graphene conducting material comprises, by weight, 0.1-0.2 part of 2-benzimidazolethiol, 3-4 parts of palm wax, 1-2 parts of 1-allyl-3-methylimidazolium chloride, 1.7-2 parts of phosphoric acid, 2-3 parts of lithium hydroxide, 0.8-1 part of ferrous sulfate, 0.1-0.2 part of glucose, 6-7 parts of acetylene black, 81-90 parts of unsaturated polyester resin, 600-700 parts of N,N-dimethylformamide, 27-30 parts of graphene oxide, 26-30 parts of hydrazine hydrate, 0.5-1 part of aluminum ammonium sulfate, 3-4 parts of dioctyl azelate, 4-5 parts of xylitol, 0.6-1 part of alkanolamide, 3-4 parts of zinc hydroxystannate, 1-2 parts of decabromodiphenyl ether, 3-5 parts of talcum powder and 1-2 parts of sodium alkyl benzene sulfonate. The flame-retardant graphene conducting material has the advantage that the chloride modified graphene with high conductivity can well disperse in the unsaturated polyester resin after being mixed with the acetylene black to form the high-conductivity compound material.

Description

technical field [0001] The invention relates to the technical field of graphene materials, in particular to a flame-retardant graphene conductive material and a preparation method thereof. Background technique [0002] The special structure of graphene endows it with many excellent properties, and its application prospects are broad. However, it is precisely because each carbon atom in the graphene structure is combined in the form of sp2 hybridization to form a large conjugated π bond on a two-dimensional plane, and two large conjugated π bonds will produce π-π interaction. At the same time, graphene has an ultra-high specific surface area, and it is easy to agglomerate with each other. It is difficult to disperse uniformly in solvents and media, which greatly limits the application of graphene. Therefore, finding an effective method to prepare dispersible graphene materials is an important direction to solve the application of graphene. By introducing some specific funct...

Problems solved by technology

[0003] At present, in addition to the excellent electrical properties of graphene materials in electronic components, another important application is to prepare high-performance nanocomposites. However, due to the very stable chemical structure of graphene, there is a very strong bond between layers. Van der Waals force is very easy to agglomerate, making it difficult to disperse graphene in most solvents and matrices, which greatly limits the application of graphene
