Background

Radial tires entered a rapid development stage in the mid-to-late 90 s of the 20 th century. At present, various companies try to improve the product quality and reduce the cost through the structural design and material modification of tires so as to obtain greater economic benefits. The material modification (except for the framework material) is mostly concentrated on the aspects of tread rubber, sidewall rubber, inner liner rubber, carcass ply rubber and the like, and the research on the bead filler material is relatively less. The bead mouth protecting rubber replaces bead mouth wrapping cloth of a bias tire to be used as a protective layer of the outer surface of the tire bead, and prevents the contact part of the tire bead and a wheel rim from wearing the outer part of the tire bead due to repeated stretching and compression strain, so the tire bead is also called as wear-resistant rubber and has high hardness, high wear resistance, high heat aging resistance and better flex crack resistance.

In the running process of the traditional tire, as rubber has a hysteresis effect, partial energy is converted into heat energy, the internal temperature of the tire is increased, the material performance is greatly reduced, the adhesive force between cord fabrics and the rubber is reduced, and finally the tire is damaged.

In the structural design of the traditional tire, due to insufficient rigidity of a tire bead, a stress strain area moves downwards under the condition of high-speed overload driving, so that stress-strain is concentrated at a turnup end point of a lower tire side cord fabric and a turnup end point of a sub-opening fabric, and the temperature of the part is greatly increased under repeated deflection deformation, so that the tire bead is damaged early.

At present, the invention patent with the patent number of 201310714825.5 uses a novel carbon fiber material carbon nanotube film to be attached to a sub-gap adhesive and is integrated with an atomic gap adhesive, so that the problem of poor heat conduction performance of the surface position in contact with a metal rim is solved, but the defect of poor wear resistance of the surface of a tire is also existed.
