Problems solved by technology

The disadvantage of the steel wire is that when it is bonded with rubber, the rubber has poor permeability, and a large amount of air remains between the steel wire strands. The friction between the steel wires of the core strands in the tire running generates a lot of heat, and the temperature of the crown and shoulders rises. delamination

Abstract

The invention provides a method of applying a belt ply all-steel cord to an all-steel radial tire. The method comprises the following steps of: preparing materials, cooking a rubber compound, supplying the rubber compound for a machine table, rolling a cord fabric, and preparing the belt ply all-steel cord. The method has the beneficial effects that 3+8x0.33HT steel wires belong to high-strength open type steel wires, and have good rubber permeability when being bonded to the rubber; the rubber compound is used for uniformly bonding the steel wires; the method can greatly reduce the occurrenceof rolling heat generation and ply separation of the tire on the basis of ensuring the load bearing performance of the tire, and effectively improves the high-speed performance of the tire, thereby prolonging the service life of the tire.

Description

technical field [0001] The invention relates to the technical field of tire manufacture, in particular to a method for applying belt steel cords to all-steel radial tires. Background technique [0002] Tires are divided into bias tires, belted bias tires and radial tires according to the arrangement angle of their skeleton materials. Radial tires are gradually replacing bias theory and becoming the development trend of tires due to their good ride comfort, wear resistance and high-speed performance. . The technical research and development of radial tires also focuses on how to improve the ride comfort of the tire, improve the wear resistance, and improve the high-speed performance. [0003] In the prior art, the radial tire crown part is composed of crown rubber and belt layer. The belt layer is also called buffer layer. Its function is to disperse the vibration and impact on the carcass, improve the rigidity of the belt layer, and effectively reduce the heat generation en...
