Abstract

The invention discloses a high-performance rubber sizing material. The high-performance rubber sizing material is prepared from the following components in parts by weight: 100 parts of composite synthetic rubber, 20 to 30 parts of thermoplastic elastomer SBS (styrene butadiene styrene), 2 to 5 parts of alumina nano-fibers, 3 to 7 parts of flaky nano-silicon, 10 to 15 parts of waste tire rubber powder, 20 to 30 parts of clay and 2 to 3 parts of coupling agent. A preparation method of the high-performance rubber compound comprises the following steps: feeding the composite synthetic rubber, thethermoplastic elastomer SBS, the waste tire rubber powder and the coupling agent into an internal mixer according to proportions and mixing for 2 to 4 minutes; then adding the alumina nano-fibers andthe clay and continuously mixing for 3 to 5 minutes; finally, adding the flaky nano-silicon and mixing again for 3 to 5 minutes, and discharging materials to a cutting machine for tabletting to obtain the rubber sizing material. The high-performance rubber sizing material has the advantages of more obvious wear resistance, higher strength, better elasticity, more excellent high and low temperature resistance, better anti-ultraviolet aging performance and weather fastness.

Description

technical field [0001] The invention relates to the technical field of rubber compounds, in particular to a high-performance rubber compound and a preparation method thereof. Background technique [0002] In recent years, with the development of society and the improvement of people's living standards, the automobile industry has developed rapidly, and consumers' requirements for cars have also begun to develop in the direction of comfort, safety, and economy. As an important part of a car, car tires are usually installed on metal rims to support the car body, buffer external impacts, realize contact with the road surface and ensure the driving performance of the vehicle. The preparation materials of automobile tires are mostly rubber materials, and the performance of these rubber materials directly affects the comfort, safety and economy of automobiles. Therefore, the rubber compound used to make automobile tires must have high load-bearing performance, traction performanc...
