Abstract

The invention relates to high-wear-resistance heat dissipation rubber and a preparation method thereof, and belongs to the technical field of rubber material preparation. The basic cupric carbonate, the self-made wear-resistant heat dissipation fiber and the wet silicon dioxide aerogel are added into the rubber base material, the specific formula proportion is limited, the heat dissipation performance and the wear resistance of the final rubber material are improved through respective synergism, and the rubber has a wide application prospect.

Description

technical field [0001] The invention relates to a high wear-resistant and heat-dissipating rubber and a preparation method thereof, belonging to the technical field of rubber material preparation. Background technique [0002] Abrasion performance is a very important performance index of rubber products. It mainly characterizes the ability of vulcanized rubber to resist material loss due to surface damage under the action of friction. At present, my country is the world's largest rubber consumer, accounting for nearly the world's rubber consumption. At the same time, domestic rubber resources are very scarce, and more than half of them need to be imported. Tires are the most rubber-consuming varieties of rubber products, accounting for about 100% of my country's rubber consumption, and the number of rubber wear and tear damage every year is very alarming. In rubber products such as tires, hoses, tapes, seals and shoe soles, people have higher and higher requirements for the...
