A kind of aviation tire provided with bead reinforcing glue

Abstract

The invention discloses an aviation tire with a tire bead reinforcing rubber and a formula of the reinforcing rubber. The aviation tire comprises a tread rubber, a reinforcing layer, a carcass cord fabric layer, an air barrier and a sidewall rubber, as well as a tire bead reinforcing rubber layer; the tire bead reinforcing rubber layer is arranged between the carcass cord fabric layer and the sidewall rubber on the upper part of the tire bead, and is cambered; the tire bead reinforcing rubber layer is arranged on the upper part of a rim and on the lower part of the central horizontal line of the tire, and clamped between the carcass cord fabric layer and the sidewall rubber; the tire bead reinforcing rubber layer is stacked and connected with the carcass cord fabric layer and the sidewall rubber. The tire bead reinforcing rubber has the performance characteristics of good thermal stability, high elasticity and low heat generation, and meanwhile, has the advantages of relatively high tensile strength, elongation at break and 300% stress at definite elongation, and relatively low permanent deformation after dynamic compression fatigue; the aviation tire is high in load and low in air pressure; under the use conditions of large stress and high deformation of the tire bead part, the quality problems such as internal disengagement of the tire bead, splitting and tire bead blasting can be avoided, and the tire is safe to use.

Description

technical field [0001] The invention relates to the field of aviation tires and polymer materials, in particular to an aviation tire provided with bead reinforcing glue. Background technique [0002] Commonly used materials for the upper part of the bead of aviation tires are innerliner rubber, carcass ply, and sidewall rubber. Because the use conditions of large aviation tires are heavy load, high speed and low air pressure, the upper part of the bead is stressed and deformed. Large size, high deformation frequency, large heat generation and high temperature in the upper part of the bead. Therefore, the existing large-scale aviation tires have quality problems such as internal voids, cracks, and bead bursts in the upper part of the bead. Contents of the invention [0003] The object of the present invention is to provide an aircraft tire provided with bead reinforcing glue and the formula of the reinforcing glue to address the deficiencies of the prior art. This bead rei...
