Abstract

The invention discloses a composite component of meridian tyre cord fabric layer and air barrier and a preparation technology. Base material rubber, an aging-proof system, a reinforcing system, a vulcanization system and a radiosensitizer are mixed at a ratio to form a mixture; the rubber mixture is mixed to smelt in an internal mixer to be prepared into a tyre body cord fabric layer component and a lining air barrier component respectively according to the production technology of the tyre body cord fabric layer and the lining air barrier component; then the tyre body cord fabric layer component and the lining air barrier component are compounded into an integral composite component on a compound machine; an electron accelcrator is used for radiating the composite component; under the condition of limited-oxygen radiation, radiation prevulcanization is carried on the composite component of the tyre cord fabric layer and the lining air barrier. The composite component of the tyre cord fabric layer and the air barrier, which is radiated by the invention, has high Green strength, stable structure size and performance, saves raw material, has small radiation dose and high production efficiency and is favourable for environment protection.

Description

Technical field [0001] The invention relates to the technical field of rubber tire manufacturing, in particular to a composite component of a radial tire ply and an airtight layer and a preparation process. technical background [0002] Tires are composed of multiple parts with rubber materials as the main base material, which are vulcanized and shaped. Radial and tubeless tires are the development trend of tires. In the traditional tire manufacturing process, the material of each tire component is required to be free from deformation, and the precise shape and size must be maintained. The carcass ply will be deformed during processing, transportation, molding and final vulcanization and setting, and the cords will be shifted or deformed. In order to avoid the displacement of the cord and the deformation of the carcass, the conventional solution is to increase the amount of rubber covering the carcass, which will inevitably increase the amount of raw materials and the thick...
