Problems solved by technology

[0005] At present, due to the limitations of vulcanization equipment and process conditions, the physical properties of the tire tread of all-steel radial tires are low, especially the wear resistance, tensile strength, hardness, and the service life of the tire is short. Bubbles and other problems occur frequently, and the tire defective rate is high

Abstract

The invention relates to a vulcanizing technique for an all-steel radial tyre. The vulcanizing technique for the all-steel radial tyre comprises the steps that high-temperature media are guided into capsules of a vulcanizing machine, the temperature of the tyre is increased and maintained for a period of time, and the vulcanizing reaction of the tyre is completed through two stages of heating vulcanization. By the adoption of the vulcanizing technique for the all-steel radial tyre, the abrasion resistance of the tread of the tyre is greatly improved, the tensile strength and hardness are improved, and the service life of the tyre is prolonged by 25% or over; and the tyre sidewall bubbles, tyre shoulder bubbles and other quality problems of the appearance of the tyre are reduced, and the defective rate of the tyre is decreased by 23% or over.

Description

technical field [0001] The invention relates to a vulcanization process for all-steel engineering machinery tires, in particular to a vulcanization process for all-steel radial tires, which belongs to the technical field of rubber. Background technique [0002] my country's tire industry started late, and the initial development speed was slow. Since the reform and opening up, with the rapid and continuous growth of the national economy and the trend of economic globalization, the industrial structure adjustment of the tire industry has accelerated, and product upgrading capabilities and comprehensive competitiveness have continued. enhanced. During this development process, our tire R&D methods and capabilities are still very backward, and we still lack the ability to continue to develop in the competition of advocating the vigorous development of environmentally friendly tires, energy-saving tires, and smart tires. [0003] As consumers understand the quality of tires, tir...
