Problems solved by technology

The rapid development of the rubber industry in recent years has put forward higher requirements for rubber products. Rubber materials must develop in the direction of refinement, functionality and diversification. However, traditional rubber products have low weather resistance and friction resistance, and are easy to crack and pull. However, due to defects such as low tensile strength and poor gas barrier performance, it can no longer meet the needs of rapid development.

Abstract

The invention relates to the technical field of materials, and particularly discloses a modified nano-composite rubber material. The nano-composite rubber material is prepared from 100 parts of rubber and 0.1-5 parts of nano-materials serving as fillers, wherein the nano-materials are one of oxidized graphene, modified white graphene and modified graphene and provided with 5-10 layers. The graphene and the white graphene are added into the rubber in a filler mode after surface modification, the oxidized graphene contains rich functional groups, good dispersion of the nano-materials in the rubber is ensured, the modified graphene, the oxidized graphene or the modified white graphene has a good gas isolation performance and high strength, and the barrier property and the mechanical strength of the rubber can be greatly improved by adding a small amount of the graphene while other performances are not affected. The modified nano-composite rubber material is simple in preparation process, low in production cost and free from environmental pollution, and large-scale industrial production is easily implemented.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a modified nanocomposite rubber material and its preparation. Background technique [0002] Rubber is an elastic polymer. As an important strategic material, it is widely used in high-tech, national economy, national defense and military industries. The rapid development of the rubber industry in recent years has put forward higher requirements for rubber products. Rubber materials must develop in the direction of refinement, functionality and diversification. However, traditional rubber products have low weather resistance and friction resistance, and are easy to crack and pull. However, due to defects such as low tensile strength and poor gas barrier performance, it can no longer meet the needs of rapid development. Rubber modification is an effective way to improve the performance of materials, and the nanomaterials graphene oxide, graphene and white graphene have great app...
