Problems solved by technology

In the traditional tire manufacturing process, each component of the tire is required to maintain precise shape and size, while the belt layer will be deformed during processing, transportation, molding and final vulcanization, and there will be leakage or deviation of steel cords Or deformed, it is easy to cause early delamination or bursting of the tire during use, making the tire lose its use value
In order to avoid the displacement of the steel cord and the deformation of the belt layer, the conventional solution is to increase the amount of rubber covering the belt layer, which will inevitably increase the amount of raw materials and the thickness of the part, resulting in a direct impact on the stability of tire quality and safety in use. influences

Abstract

The invention discloses a meridian tyre belted layer component and a preparation technology thereof. Base material rubber, an aging-proof system, a reinforcing system, an adhesion system, a softener, a vulcanization system and a radiosensitizer are mixed at a ratio to form a mixture; the mixture is performed with three-stage mixing to prepare mixed rubber; a steel wire tire cord is made into a meridian tyre belted layer component by coating and calendaring; on a transmission device below a constant tension traction beam below an electron accelcrator, the tyre belted layer component is performed with radiation processing by adjusting the beam current energy of the electron accelcrator; under the condition of limited-oxygen radiation, the preparation of the meridian tyre belted layer component is finished. The radiated belted layer glue stock of the invention has high Green strength, stable structure size and performance, lowered belted layer thickness, small amount of rubber, high production efficiency and energy saving, lowers investment cost and protection cost, is favourable for environment protection, and can improve the quality of meridian tyres.
