Problems solved by technology

[0003] Existing graphene and eucommia gum are used as reinforcing materials. The prerequisite for improving the performance of rubber materials is that graphene and eucommia gum should be dispersed in the rubber matrix material to ensure strong interaction between graphene, eucommia gum and rubber molecules. It is difficult to ensure the dispersion effect of graphene in the rubber processing technology. Graphene itself is prone to agglomeration during the addition process, resulting in poor reinforcing effect of graphene on rubber materials, thus affecting the use strength of the prepared rubber composite material. , we propose a method based on a rubber composite blended with pure carbon graphene and eucommia natural rubber to solve the above problems
