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 are...

Embodiment 1

[0028] This embodiment is carried out by using the method of the present invention for treating dipped cord fabric fibers or cords based on high-energy electrons. The selection range of the voltage is between 200~600KV, and the selection range of the radiation absorbed dose is between 0.5~60KGy. In this embodiment, the electron beam irradiation voltage is adjusted to 200KV, the radiation absorption dose is 20KGy, and the impregnating glue is cured.

[0029] In order to ensure the best curing effect, the cord fibers or cords can always be cured in an oxygen-limited environment made of protective gas. The main purpose is to prevent the occurrence of oxygen inhibition. The protective gas can be selected from nitrogen, carbon dioxide, One or more combinations of inert gases. In order to ensure continuous production and uniform irradiation, a transmission system, such as a conveyor belt or a conveyor roller, can be set up to transport the cord fabric fibers or cords.

Abstract

The invention provides a method for processing gum dipping tyre fabric fibers or cord threads based on high-energy electrons and belongs to the technical field of tyre manufacturing. The tyre fabric fibers or the cord threads dipped with irradiation solidification dipping gum are subjected to high-energy electron irradiation solidification, wherein irradiation absorbed dose is 0.5-60 KGy. Compared with the prior art, the method has the advantages that a large amount of energy does not need to be consumed, the purpose of energy saving and emission reducing is achieved, meanwhile, time consumed in the irradiation solidification process is short, production efficiency is greatly improved, compared with hot drying equipment, related production equipment is small in size and simple in structure, and cost and maintaining can be controlled easily.

Description

technical field [0001] The invention belongs to the technical field of tire manufacturing and relates to a method for processing dipped cord fabric fibers or cords based on high-energy electrons. Background technique [0002] At present, the production of cord fabric mainly includes 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 strokes in the furnace (th...
