Method for processing impregnated cord fabric fiber or cord thread based on ultraviolet light and high-energy electrons

Abstract

The invention provides a method for processing an impregnated cord fabric fiber or cord thread based on ultraviolet light and high-energy electrons, and belongs to the technical field of tire manufacturing. The method comprises the following steps: firstly, carrying out ultraviolet irradiation on the cord fabric fiber or cord thread impregnated with an irradiation-curing impregnating adhesive; and carrying out high-energy electron irradiation curing, wherein the irradiation absorption dose is 10-100KGy. Compared with the prior art, the method has the beneficial effects that a lot of energy sources do not need to be consumed; the targets of saving energy and reducing emission are achieved; meanwhile, the elapsed time of the irradiation curing process is short; the production efficiency is greatly improved; the anaerobic polymerization process is not required; compared with thermal drying equipment, production equipment provided by the invention is small in volume, simple in structure, and relatively easy to repair; and the cost is relatively easy to control.

Description

technical field [0001] The invention belongs to the technical field of tire manufacturing and relates to a method for treating dipped cord fabric fibers or cords based on ultraviolet light and high-energy electrons. Background technique [0002] At present, the production of cord fabric mainly includes the three major production processes of raw silk, twist weaving, and dipping; the dipping process includes three major processes of dipping, drying, and shaping. [0003] As far as the drying process is concerned, the hot air drying technology is currently used to dry the dipped cord fabric. The specific method is that the dipping machine dips the cord fabric and passes through the roller group, squeezes out the excess glue and flattens it, and then goes to the drying furnace. , through the hot air circulation method, the hot air is sprayed vertically from the gas collecting pipe in the furnace to the cord fabric in the form of thin streams. The cord fabric passes through 4 st...

AI Technical Summary

Problems solved by technology

[0005] 1. High energy consumption: the whole process needs to consume a lot of energy to provide hot air;

[0006] 2. Large pollution: due to the low solid content of the impregnated glue used in conjunction with the hot air drying technology, heating causes a large amount of volatile solvents to volatilize, resulting in VOC emissions, which seriously pollute the environment;

[0007] 3. Low efficiency: the drying process takes a long time, resulting in low overall efficiency;

[0008] 4. Large equipment: The equipment not only covers a large area and is high in height, but also has a complex structure and complex maintenance

However, the high-energy electron beam drying method often needs to be combined with nitrogen, carbon dioxide, inert gas protection or high-vacuum environment protection, and the processes and equipment involved are very complicated.
