Problems solved by technology

However, in the current industrial production, limited to the technical conditions of tires, the compounding of graphene oxide and rubber generally adopts the mechanical blending method. Although direct mechanical blending is simple and easy, it is difficult to peel off graphene oxide and evenly disperse it in the rubber. In the matrix, and the high shear force during the mechanical blending process will break the graphene oxide sheet

Abstract

The invention relates to a high-performance tire containing oxidized graphene and a preparing method thereof. Tread rubber is basically prepared from, by mass, 80-100 parts of matrix rubber, 50-70 parts of high dispersion white carbon black, 4-6 parts of silane coupling agent, 5-10 parts of carbon black, 0-10 parts of oxidized graphene rubber master batch, 2-8 parts of plasticizer, 1-3 parts of active agent, 1-3 parts of antiager, 1-3 parts of vulcanization accelerator, 1-2 parts of common sulphur and 0-0.3 part of scorch retarder. The oxidized graphene rubber master batch is the compound of oxidized graphene and natural rubber, and the mass of oxidized graphene is 5-15% of the total mass of the rubber master batch. By the adoption of oxidized graphene, the properties, including tensile strength, stress at definite elongation, hardness and wear resistance, of the composite tread rubber material are improved.

Description

technical field [0001] The invention relates to a high-performance tire containing graphene oxide, a preparation method and a preparation process thereof. Background technique [0002] Tires are one of the most important components of a car. The tire tread must provide the grip or traction necessary for driving, braking and steering. The tread compound is specially configured to balance wear, traction, handling and rolling resistance. Tread compounds must be effective in a variety of driving conditions, including wet, dry or snow-covered roads, and meet customer expectations for tires with high wear resistance, high durability, low rolling resistance, and environmental protection. [0003] Graphene oxide flakes are the product of graphite powder after chemical oxidation and exfoliation. Graphene oxide is a single atomic layer that can expand to tens of microns in lateral dimension at any time. Therefore, its structure spans the typical of general chemistry and materials scie...
