High-strength silica-based graphene conductive material and preparation method thereof

Abstract

The invention discloses a high-strength silica-based graphene conductive material. The high-strength silica-based graphene conductive material is prepared from the following raw materials in parts by weight: 0.3 to 1 part of coconut acid diethanolamide, 3 to 4 parts of wollastonite powder, 5 to 6 parts of ethylhexyl epoxy tetrahydrophthalate, 1 to 2 parts of chlorination-1-allyl-3-methylimidazole, 1.7 to 2 parts of phosphoric acid, 2 to 3 parts of lithium hydroxide, 0.8 to 1 part of ferrous sulfate, 0.1 to 0.2 part of glucose, 6 to 7 parts of acetylene carbon black, 81 to 90 parts of unsaturated polyester resin, 600 to 700 parts of N,N-dimethylformamide, 27 to 30 parts of graphene oxide, 26 to 30 parts of hydrazine hydrate, 7 to 10 parts of tetraethyl orthosilicate, 0.8 to 1 part of zinc acetylacetonate, 0.1 to 0.2 part of 1,2-dimethylimidazole, 1 to 2 parts of aluminum magnesium silicate, 1 to 2 parts of ammonium octamolybdate and 1 to 2 parts of polyacrylamide. Chlorination modified grapheme has good conductivity, is blended with the acetylene carbon black, and can be well dispersed in the unsaturated polyester resin to form a composite material with high conductivity.

Description

technical field [0001] The invention relates to the technical field of graphene materials, in particular to a high-strength silicon-based 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 sp...

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
