Description

Technical Field

[0001] The utility model relates to the technical field of UV curing, in particular to a low-temperature double-sided irradiation device. Background Art

[0002] A UV irradiation machine is used to carry out graft copolymerization reaction on the material. Taking EVA material as an example, in order to make the surface of the EVA foam sole of sports shoes easy to bond, UV irradiation is generally used to make the surface of the EVA foam sole of sports shoes undergo graft copolymerization reaction. The EVA foam sole of sports shoes is first coated with UV treatment agent, and then the solvent is heated and dried, and then exposed to ultraviolet light. The photoinitiator in the UV treatment agent undergoes fission, releasing free radicals, which initiate a graft copolymerization reaction with the surface of the shoe material.

[0003] The current UV curing light source mainly uses a high-pressure mercury lamp. Since the temperature generated by the high-pressure mercury lamp is relatively high during curing, it is difficult to cure temperature-sensitive materials such as EVA. Excessive temperature can easily cause the material to foam, shrink or deform, so a refrigerator or other heat dissipation equipment is needed to cool it down. At the same time, the energy consumption of the high-pressure mercury lamp is relatively high. Therefore, the existing UV irradiation machine is not suitable for quality improvement of EVA materials.

Therefore, there is no need for traditional freezers to cool down, which can save freezing costs and processes. At the same time, the use of low-temperature cold light treatment with UVC lamps has the advantages of no foaming, no shrinkage, and no deformation compared to high-temperature treatment with high-pressure mercury lamps.
