Abstract

The invention relates to the technical field of rubber composite materials, in particular to a graphene modified rubber composite material for a tire tread and a mixing method of the graphene modified rubber composite material. The graphene modified rubber material is prepared from the following raw materials: a matrix rubber material, a modified graphene material, a vulcanizing agent, a flow promoting agent and the balance of an organic solvent, the modified graphene material at least comprises the following raw materials: graphene powder, polyvinyl chloride powder, vinyl acetate, talcum powder and the balance of N, N-dimethylformamide solution and water; according to the graphene modified rubber composite material for the tire tread and the mixing method of the graphene modified rubber composite material, the added modified graphene material is physically modified by blending the graphene with the polyvinyl chloride, so that the mechanical property of the graphene material is improved, and the characteristics of the polyvinyl chloride are introduced into the matrix rubber material for blending through the graphene; the strength and the hardness of the composite material can be improved, and meanwhile, the abrasion loss and the puncture resistance of the composite material can be reduced, so that the composite material can be better applied to a tire table top.

Description

technical field [0001] The invention relates to the technical field of rubber composite materials, in particular to a graphene-modified rubber composite material for tire treads and a mixing method thereof. Background technique [0002] Tire is one of the important parts of the car. It is in direct contact with the ground, and together with the suspension of the car, it alleviates the impact of the car when it is running, and bears the weight of the car at the same time. The traditional tire tread is made of rubber material, which has the advantages of good dynamic performance, excellent elasticity, low heat generation during driving, and comfortable ride. [0003] Graphene is the most researched new type of carbon nanomaterial in the world. It has the thinnest and lightest single-layer carbon atom sheet structure in the world. It has a large specific surface area, super hardness, flexibility, and super high Thermal and electrical conductivity. [0004] Generally, those wi...
