Problems solved by technology

The preparation method of the present invention is simple and easy, has no environmental pollution, and is easy to realize industrial production, and the magnetic hollow graphene-based composite microspheres prepared at the same time have high specific surface area and developed pore structure. The method provides a new method for the preparation of graphene composite materials. This is an idea, but the prepared graphene composite microspheres cannot be applied in the field of engineering polymers
[0008] Therefore, new technologies need to be introduced in the field of polymer preparation to solve the problem of uneven distribution of graphene in it.

Abstract

Theinvention discloses a microsphere graphene reinforced master batch and a preparation method. In a glass microsphere forming process, graphene adheres to the surface of the glass microsphere, so as to form microsphere graphene with graphene as a wrapping layer and glass microsphere as a core after condensation. The graphene fulfills a higher potential in interface characteristic, further, the graphene and the glass microsphere are combined tightly, so that the microsphere graphene is easy to flow and scatter. The graphene scatters in a sphere state, thereby being prevented from gathering effectively. The microsphere graphene reinforced master batch with a reinforcing function can be obtained by assisting pelletizing of high-molecular polymer. When the microsphere graphene reinforced master batch is used for reinforcing materials like plastics and rubber, the graphene is tightly combined with the glass microsphere so as to scatter in the microsphere state in the system, so that the scattering function is improved substantially; in addition, the graphene fulfills a higher potential in interface characteristic, that is, the graphene can be better wound the plastics and rubber. The preparation method disclosed in the invention is simple, a wide range of raw materials can be used, and the preparation method is contamination-free, is low in cost, and is easy to realize large-scale industrial production.
