A low heat generation, high elasticity aviation radial tire shoulder pad rubber

Abstract

The invention provides an airplane radial tire shoulder wedge with low heat generation and high elasticity properties. The airplane radial tire shoulder wedge is prepared from raw materials in parts by weight as follows: natural rubber, a reinforcing system, a silane coupling agent, an anti-ageing agent, a stabilizer and the like through banburying by a banbury mixer and extruding by an extruder, and is attached to the tire shoulder part. The airplane radial tire shoulder wedge has the advantages that the airplane radial tire shoulder wedge has low heat generation, high elasticity, good flexing resistance and good heat stability, the hardness and stress at definite elongation are reasonably matched with peripheral parts, and delamination caused by the fact that the tire shoulder wedge and the peripheral parts produce different deformation in a stress state can be prevented.

Description

technical field [0001] The invention relates to a polymer material, in particular to a low-heat-generating, high-elastic aviation radial tire shoulder pad rubber. Background technique [0002] The shoulder area of ​​aviation radial tires has large deformation, high heat generation, and extremely complex stress distribution. It is the area where defects are most likely to occur during tire use, and defects are relatively concentrated, including shoulder voids, shoulder cracks, delamination, etc., which affect the stability of aviation tires. Safe to use. Shoulder pad rubber is an important part of aviation radial tires. The shoulder pad rubber is located on the shoulder of the finished tire, which plays a role in the transition from the carcass to the belt, flattening the curved surface of the carcass layer, so that the belt layer can be as smooth as possible. Straightness determines the stress state and deformation of each part of the shoulder. [0003] The shoulder pads o...

AI Technical Summary

Problems solved by technology

[0003] The shoulder pads of aviation radial tires currently used are prone to delamination, bulging, and tread throwing on the shoulders, which will reduce the service life and safety of the tires.
