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

Embodiment 1

[0024] refer to figure 1 , this embodiment is a technical process for curing and drying dipped cord fabrics in a heat-drying manner, which belongs to the prior art, and includes sequentially guiding the cloth to discharge to the cloth storage rack, then entering the dipping machine for dipping, and then vacuum suction Recover the excess impregnated glue, then dry it through the drying oven, then enter the shaping oven for shaping, and finally wind up the material on the cloth storage rack.

Embodiment 2

[0026] refer to figure 2 , this embodiment is the process flow of the method of drying dipped cord fabrics based on high-energy electrons according to the present invention. The difference from the prior art in Example 1 is that the cord fabrics are dried by high-energy electronic drying equipment after being vacuum-absorbed. The drying process is completed under the irradiation conditions of high-energy electrons.

Embodiment 3

[0028] With respect to the above-mentioned embodiment 2, this embodiment adopts the method of high-energy electron irradiation to cure the cord fabric impregnated with radiation-cured impregnating glue, wherein the selection range of the voltage is between 200 and 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 fabric 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, and inert gas. A combination of one or more. In order to ensure continuous production and even and stable irradiation of the cord fabric, a transmission system, such as a conveyor belt or a conveyor roller,...

Abstract

The invention provides a high-energy electron based method for drying dipped cord fabric, and belongs to the technical field of tire manufacture. According to the method, the cord fabric dipped with irradiation curing dipping rubber is subjected to high-energy electron irradiation curing, wherein the irradiation adsorption dose is 0.5-60 KGy. Compared with the prior art, the high-energy electron based method has the benefits as follows: a large amount of energy is not required to be consumed, and purposes of energy saving and emission reduction are achieved; meanwhile, an irradiation curing process consumes very short time, and the production efficiency is increased greatly; and involved production equipment is smaller in size and simple in structure compared with thermal drying equipment, and the cost and maintenance are easy to control.

Description

technical field [0001] The invention belongs to the technical field of tire manufacturing, and relates to a method for drying dipped cord fabrics, in particular to a method for drying dipped cord fabrics based on 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...
