[0012] Example: P235 / 75R15 radial tire

[0013] Below in conjunction with specific embodiment further describe the present invention in detail,

[0014] A thinning belt part for radial tires, comprising a belt skeleton 1 and a rubber covering layer 2, the skeleton 1 is made of a high-modulus cord material, including steel cords or fiber cords, and the cord layer The number is single-layer or multi-layer, and the rubber layer 2 is raw rubber of natural rubber or a blend of natural rubber and synthetic rubber. According to the formula of 100 parts by mass, 5 parts of sensitizer triallyl isocyanurate are added Acetate (TAIC), mixed in a 50L internal mixer according to the conventional process, and made into a thinning belt layer sheet. Adjust the roller pitch of the calender, and perform steel cord expansion, calendering, gluing and winding according to the conventional process to obtain a double-layer belt part with a standard length and width and a thickness of 2.4 mm. Fix th...

Abstract

The invention discloses a thinned belted layer component for a radial tire. The thinned belted layer component comprises a belted layer framework and a rubber coating layer, wherein the framework is made of a high-modulus cord thread material which comprises steel wire cord threads or fiber cord threads, and one or more cord thread layers are arranged; the rubber coating layer is made of natural rubber or a blend of the natural rubber and synthetic rubber; cord thread expansion, calendaring and rubber coating are carried out according to a radial tire belted layer production process to manufacture a thinned belted layer piece with a standard width, and the rubber layer thickness of the component is thinned by 3-10 percent compared with that of a component produced by a traditional process; and then, the thinned belted layer piece is radiated and prevulcanized by adopting an electronic accelerator radiation device to prepare a thinned belted layer component. The thinned belted layer component has a thinned belted layer structure and has the advantages of low rubber raw material dosage, high Green strength of the coated rubber, good rubber layer uniformity and strong structure stability, so that the performance and the quality of a manufactured tire is greatly improved, and the thinned belted layer component is suitable for preparing a high-performance radial tire.

Description

Technical field [0001] The invention relates to the fields of rubber tire processing and radiation technology application, in particular to a thinning belt layer component for radial tires. Background technique [0002] The tire industry has developed rapidly with the improvement of automobiles and roads. At the same time, the development of expressways, the increase of automobile speed and load capacity have put forward more stringent requirements for tires. In order to meet the new requirements, the tire structure design and preparation process must be accelerated. improvement of. At present, radial tires are developing in the direction of flattening, high speed, environmental protection, functionalization and production automation. The belt layer of a radial tire is the main stress-bearing part of a radial tire. It is generally composed of one or more layers of steel cord. strength. The belt layer is the unique structure of the radial tire, and its structural design is...
