The inventor finds that graphene is not easy to disperse uniformly in the silica gel system in the research and development process, and the smaller the particle size of the graphene is, the easier the graphene is agglomerated. In view of this, the inventors have found through a large number of experiments that graphene with a smaller particle size can be combined with white carbon black through adsorption, and then graphene with a larger particle size is redispersed, wherein the dispersibility of graphene is good, the obtained dispersion system is stable, and the performance of the obtained graphene composite silica gel is excellent.

Preferably, the components are mixed specifically as follows:

The remaining components in step (a) are those for silica gel, bridging agent, white carbon black and silicone oil, such as: if the graphene material with the particle size smaller than 1 mu m is added into the silica gel, then the rest components are a bridging agent, white carbon black and silicone oil; if the graphene material with the particle size smaller than 1 mu m is added into the silica gel and the bridging agent, then the rest components are white carbon black and silicone oil; and so on.

According to the invention, the graphene material with small particle size is added firstly, and is easy to agglomerate and not easy to disperse, so that the graphene material with small particle size is mixed with any one or more of other components, the graphene material is partially dispersed firstly, then the other components are added, the graphene material is mainly combined with white carbon black in an adsorption mode, the graphene material in adsorption is in a relatively stable state, and a good environment is provided for adding large-particle-size graphene; at this time, large-particle-size graphene is added, and the large-particle-size graphene material mainly exists in a dispersed form in the graphene composite silica gel and is in a stable and balanced state. The graphene composite silica gel prepared finally is uniform and stable in dispersion, the graphene can fully play the functions of the graphene, and other components are matched, so that the prepared graphene composite silica gel is excellent in performance.

In the experimental process, it is unexpectedly found that graphene with small particle size and white carbon black directly have a certain adsorption force, and the graphene with small particle size can be adsorbed on the white carbon black, so that the white carbon black and the graphene with small particle size are firstly mixed and mutually adsorbed, namely, the graphene is pre-dispersed through the white carbon black, then silica gel, a bridging agent and silicone oil are added, and the three components can be added together or independently and not limited in sequence, so that the graphene and the white carbon black are dispersed together in a system to form a relatively uniform system. At the moment, the graphene with larger particle size is added, so that the graphene is easier to disperse, the method is simple and easy to implement, the graphene in the obtained product is uniformly dispersed, and the product performance is excellent.

Since graphene with small particle size is easy to agglomerate and not easy to disperse, preferably, in the step (a), the graphene material with particle size smaller than 1 μm is mixed with other components in batches, and the component containing the graphene material is not more than 10 times of the component without the graphene material in mass when mixed each time.
