Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to an impact-resistant rubber material and a preparation method thereof. Background technique [0002] Graphene-based polymer nanocomposites are considered to be the most promising fields for graphene applications. The main reason is that on the one hand, the products of polymer materials play an increasingly important role in people's lives, and have surpassed inorganic non-metallic materials and metal materials to become the most used materials in people's lives; on the other hand, graphene and Its derivatives, blackene oxides, each have a unique two-dimensional structure and excellent performance, and are ideal fillers. Currently, there are three main preparation methods for the preparation of graphene / polymer composites: flame-melt blending, solution blending, and in-situ polymerization. These three methods have their own advantages and disadvantages: melt blending ca...

Problems solved by technology

However, at present, the functionalization method of graphene is not very mature and needs to be further improved. In order to realize its industrialization, in-depth research is needed, especially how to use covalent and non-covalent bond modification methods to have special structures and properties. Combining chemical molecules with graphene to give full play to the advantages of both is the focus of current research; it has been found that the main problem in the process of preparing graphene oxide / polymer composites is that graphene oxide is easy to agglomerate, and in The dispersion in the polymer is not uniform, and the bonding interface between graphene oxide and polymer is not good, which ultimately leads to the low comprehensive performance of graphene oxide / polymer composites, which limits its further industrial application.
