Embodiment Construction
[0021] 1. Preparation of graphene slurry:
[0022] Get 200 grams of 400 order flake graphite powder, 100 grams of MFE-W4 vinyl ester resin, 50 grams of KH-560 silane coupling agent, 50 grams of IC-913 nanometer dispersion agent (Guangzhou Anglian Trading Company), 50 grams of organic bentonite, Fumed silica 50 grams, NMP 500 grams, 1000 grams in total. The above-prepared solid-liquid components are mixed evenly, and put into ball milling tanks respectively. The grinding medium is made of stainless steel balls, and the mass ratio of balls to materials is 6:1.
[0023] The grinding equipment is an ultrasonic-assisted solid-liquid reaction ball mill as disclosed in ZL201420081151.X. The rotation speed of the ball mill was set at 450r / min, and the grinding time was 6 hours, of which the first 4 hours were normal grinding, and the ultrasonic-assisted dispersion ball mill was turned on for the next 2 hours. After the grinding is completed, open the tank to take the material, and u...

Description
technical field [0001] The invention relates to the technical field of new materials and applications, in particular to the application of graphene, and also to the technical field of coating production. Background technique [0002] Graphene is a new material with a single-layer and few-layer sheet structure composed of 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. It is recognized as the best thermal conductivity material in the world. [0003] The reason why graphene has excellent thermal conductivity is the characteristics endowed by its special stable structure, and its "carbon-carbon" bond is only 1.42 Aring. The connection between carbon atoms inside graphene is very flexible. When an external force is applied to graphene, the surface of the carbon atoms will bend and deform, so that the carbon atoms do not need to be rearranged to adapt to the external force, thereby m...
