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

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 ultraviolet light and high-energy electrons of the present invention. The difference from the prior art in Example 1 is that after the cord fabrics are vacuum-absorbed, they are firstly dried by ultraviolet light. Double-sided irradiation, and then dried by high-energy electronic drying equipment, so it can be seen that the drying process is completed under irradiation conditions.

Embodiment 3

[0028] As for the above-mentioned embodiment 2, this embodiment adopts a method based on ultraviolet light and high-energy electron irradiation to cure the cord fabric impregnated with radiation-curable impregnating glue, wherein the selection range of the voltage is between 200 and 600KV, and the radiation absorption The selection range of dose is between 10~100KGy. 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] The radiation-curable impregnating glue of this embodiment is composed of 100 parts of polyisocyanate, 70 parts of acrylate, 10 parts of vinyl ether monomer and 0.2 part of photoinitiator in parts by weight. Among them, polyisocyanate can be selected between 100~300 parts, acrylate can be selected between 70~240 parts, vinyl ether monomer can be selected between 10~40 parts, and photoinitiator can be selected between 0.2~240 parts. Choose between 30 c...

Abstract

The invention provides a method for drying a dipped cord fabric based on ultraviolet light and high-energy electrons, belonging to the technical field of the tire manufacturing. The method comprises the steps of carrying out UV irradiation on the front side and the reverse side of the cord fabric dipped with impregnating adhesive which can be solidified through irradiation, and then performing irradiation solidification by high-energy electrons, wherein the irradiation absorption dose is 10-100KGy. Compared with the prior art, the method has the beneficial effects that a great amount of energy is not required to be consumed, and the purposes of saving energy and reducing emission can be achieved; the irradiation solidification time is very short and the production efficiency is greatly improved; the oxygen polymerization inhibition resisting process is not required to be adopted; and the related production equipment has smaller volume compared with the heat drying equipment, has a simple structure, has easily-controllable cost and can be maintained easily.

Description

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