Abstract

The irradiation cross-linking pre-treatment method for structure material of radial tire features that the structure material belt of 0.5-2.5 mm thickness for tire foundation, crown belt, etc is made to pass through the scanning window of electron accelerator at the speed of 1-40 m/min for being irradiated with electron beam of 1-100 mA to result in absorption dosage of 20-60 kgy. The said irradiation cross-linking pre-treatment method can raise the tensile strength, stability, ageing resistance, etc of the material, and may be also used for treating other material of radial tire.

Description

technical field [0001] The invention relates to the technical field of radiation application, in particular to a radiation crosslinking pretreatment method for structural materials of radial tires (including carcass, cap ply, belt ply, airtight layer, etc.). Background technique [0002] In the current domestic tire manufacturing process, after the masterbatch is heat-smelted and pressed to form strips such as carcass, cap ply, belt ply, and inner liner, it enters the heat vulcanization and molding process. The belt layer, belt layer, carcass, airtight layer, etc. are made into radial tires according to certain process requirements. With the development of society and economy, the demand for tires is increasing day by day, but the raw material for making tires—natural rubber resources is limited, and the cost is also rising. How to reduce the use of raw materials, improve the yield of tires, and reduce production costs and energy Consumption is an ur...
