Problems solved by technology

When graphene is supplied and promoted in the form of powder, the first problem that users encounter is that the agglomerates are difficult to disperse; even if some developers provide graphene dispersion slurry, there are unstable and re-agglomerated nanoparticles, which loses practicality. significance

Abstract

The invention discloses a graphene dispersed slurry which consists of the following raw material formula components in parts by mass: 20-25 parts of micro-crystal graphene, 4-5 parts of nano aluminum oxide, 3-4 parts of nano silicon dioxide, 3-5 parts of carbon fiber, 8-10 parts of polyvinyl alcohol, 3-5 parts of zinc stearate, 2-3 parts of sodium polyacrylate, 3-4 parts of sodium lignin sulfonate, 3-5 parts of sodium dodecyl sulfonate, 5-6 parts of propanethiol, 3-5 parts of gamma-trimethoxysilylpropanethiol, 2-3 parts of tetrabutyl titanate, 3-4 parts of carbon black, 3-5 parts of hydroxyethyl cellulose, 4-5 parts of titanium dioxide, 5-6 parts of polyester resin, 6-8 parts of gum dammar, 3-5 parts of talcum powder, 35-40 parts of methyl isobutyl ketone and 35-40 parts of propylene glycol monomethyl ether acetate. By adopting the graphene dispersed slurry, the problem that aggregate is hard to disperse can be well solved, and the phenomenon that dispersed graphene is aggregated again as nanoparticles are not stable can be avoided.

Description

technical field [0001] The invention relates to the technical field of a dispersion slurry, in particular to a graphene dispersion slurry. Background technique [0002] Graphene is a monolithic or few-layer sheet nanomaterial composed of two-dimensional carbon atoms. It is recognized as the thinnest but also the hardest nanomaterial in the world. Its thermal conductivity is as high as 5300W / m·K. The discovery of the best heat-conducting material has set off an extensive research boom in the global scientific community. However, the research hotspots and difficulties of graphene are nothing more than two key points: one is to solve the problem of industrialization; the other is to solve the problem of industrial application technology. Only by solving these two key problems well can we find a development path for graphene. [0003] At present, there is a research upsurge in developing graphene in the scientific community. This research upsurge has also attracted the intere...
