Abstract

The present invention provides graphene dispersion slurry and organic and inorganic general priming paint modified by the graphene dispersion slurry, and relates to the technical field of chemical industry. First, the graphene dispersion slurry with a good dispersion effect is prepared, the graphene dispersion slurry comprises graphene powder, an ultra-dispersing agent, a silane coupling agent, a multi-functional additive, polyketone resin, hydrated magnesium silicate and a solvent, wherein the mass ration of graphene powder to ultra-dispersing agent to silane coupling agent to multi-functional additive to polyketone resin to hydrated magnesium silicate to solvent is 8-10: 5-10:3-5:1-3:7-12:0.5-1: 75.5-59. The graphene dispersion slurry is used for modifying the organic and inorganic general priming paint, so that paint films of the organic and inorganic general priming paint have self-repairing function, and have good salt spray resistance, and in addition, the priming paint production cost can be reduced, and corrosion resistance and mechanical properties of the priming paint can be improved.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a graphene powder slurry and an organic universal primer and an inorganic universal primer made from the 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 ...
