Abstract

The present invention provides a recipe of aviation tyre tread rubber applicable to the marine environment. The rubber is made of natural rubber which is used as the main material, butadiene styrene rubber, cracking prevention agent, heat stabilizer, high abrasion-resistant carbon black with novel process and high structure, high dispersion white carbon black, silicon alkyl coupling agent, para-phenylene diamine type anti-aging agent and ketoamine type anti-aging agent which are used as the main auxiliary materials according to a certain proportion. The tyre tread rubber provided by the present invention has the advantages of UV-light resistance, ozone resistance, atmosphere aging resistance, salt atmosphere resistance and fungus corrosion resistance, as well as good comprehensive performance required by aviation tyre; therefore, the present invention is particularly applicable to aviation tyres used in the marine environment.

Description

Technical field: [0001] The invention relates to an aircraft tire tread rubber material, in particular to the formulation of the aircraft tire tread rubber material adapted to the marine environment. Background technique: [0002] When aviation tires are used in a marine environment, due to the refraction and reflection of seawater, the tires are particularly exposed to ultraviolet radiation, especially in summer, when the strong sunlight is exposed, the temperature of the metal deck is higher, and the salt spray and air humidity on the sea surface are high. , The surface of the tire is easy to breed mold. At present, aviation tires used in such an environment are not capable of resisting ultraviolet rays, high temperature, heat and humidity, salt spray and mold. It is necessary to develop aviation tires with higher performance to adapt to the marine environment. Invention content: [0003] The purpose of the present invention is to provide an aviation tire tire suitable ...
