Process for producing automobile tyre

Abstract

The invention discloses a process for producing an automobile tyre, and relates to the field of production of automobile accessories. The process for producing the automobile tyre comprises the following steps: banburying of ingredients, preparation of a rubber component, the preparation of a semi-finished product, and forming procedure and vulcanization procedure of the tyre, wherein during the banburying of ingredients, dilute sulfuric acid is added, and the ingredients are refined in a hot sulfuric acid environment at the temperature of 320 to 350 DEG C, so that the mixing uniformity of various rubber materials is improved, and the physical and mechanical properties and the technological operation performance required by the technology are met better; the semi-finished product is treated in four steps and is extruded separately, so that the size and weight of respective components are improved, the standard specified by the technology is met better, the mutual effect and influence between respective components are avoided, and the effectiveness and safety of the production are ensured; the temperature range is controlled strictly in a calendaring process, so that a framework material is combined with the rubber material better to achieve a uniform cord density, and the thickness uniformity of rubber materials on two surfaces of a cord is improved.

Description

technical field [0001] The invention belongs to the field of auto parts production, and more specifically, the invention relates to an auto tire production process. Background technique [0002] At present, the rapid development of China's economy will inevitably lead to the rapid development of the transportation industry. By 2010, it is estimated that the passenger volume will increase by about 60%, and the freight volume will increase by about 35%. Tonnage and low-speed trucks are developing to high-tonnage and high-speed heavy-duty vehicles, from bulk cargo to container load, from high-density short-distance transportation to high-density long-distance or ultra-long-distance transportation. It must expand The application of large-scale radial truck tires, the invention patent of application number CN200610014969.X, solves the problems of tires that are afraid of being punctured, explosive and needs to be inflated at any time, endows tires with good elasticity, ensures t...

[0002]At present, the rapid development of China's economy will inevitably drive the rapid development of the transportation industry. By 2010, it is estimated that the passenger volume will increase by about 60%, and the freight volume will increase by 35% At the same time, the development mode of China's road transportation has changed from low-tonnage and low-speed trucks to high-tonnage and high-speed heavy-duty trucks, from bulk cargo to container load, from high-density short-distance transportation to high-speed The development of density long-distance or ultra-long-distance transportation. It must expand the application of large-scale radial truck tires. The invention patent application number is CN200610014969. Elasticity ensures the durability of the elasticity, and at the same time, it is easy to realize the adjustability of the elasticity of different types of tires. However, the mixing quality of various rubber materials is not uniform enough, and the physical and mechanical properties and technical operation performance of the technical requirements are not fully met; each The size and weight of these parts do not meet the standards specified in the technical regulations; the lamination of the skeleton material and the rubber material cannot achieve uniform cord density, and the thickness of the rubber material on both sides of the cord is not uniform
