Problems solved by technology

[0002] Existing aviation tire tread rubber has the disadvantages of insufficient thermal stability and wear resistance
Aviation tires take off and land at high speed under high load, which makes the tire tread rubber in a high temperature state. Due to the degradation of rubber, the tread rubber wears quickly and the service life is shortened. This not only increases the workload of aircraft maintenance personnel, but also increases Aircraft Operating Costs

Abstract

The present invention discloses a recipe of high abrasion-resistant aviation tyre tread rubber. The tyre tread rubber is mixed and refined through a mixing roll, including natural rubber which is used as the main material, high abrasion-resistant carbon black with novel process and high structure, high dispersion white carbon black, silicon alkyl coupling agent and heat stabilizer which are used as the auxiliary materials, as well as zinc oxide, stearinic acid, para-phenylene diamine type anti-aging agent, ketoamine type anti-aging agent, protective wax, insoluble sulfur, sulfenamide type accelerator, etc. The tyre tread rubber provided by the present invention has the advantages of high tensile strength, high tearing strength, low dynamic heat generation, good thermal stability and high abrasion resistance, thus prolonging the service life of the aviation tyre and ensuring the flight safety.

Description

Technical field: [0001] The invention relates to an aviation tire tread rubber, in particular to the formulation of a high wear-resistant aviation tire tread rubber. Background technique: [0002] Existing aviation tire tread rubber has the disadvantages of insufficient thermal stability and wear resistance. Aviation tires take off and land at high speed under high load, which makes the tire tread rubber in a high temperature state. Due to the degradation of rubber, the tread rubber wears quickly and the service life is shortened. This not only increases the workload of aircraft maintenance personnel, but also increases Aircraft operating costs. Invention content: [0003] The purpose of the present invention is to provide a formula of aviation tire tread rubber with low heat generation, good thermal stability and high wear resistance. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] A high-wear-resistant avia...
