Oil coating layer at the bottom of oil coating layer replacement heat curing-type at the bottom of end oil coating layer employing UV tin graphed sheet.Oil at the bottom of oil coating layer use UV tin graphed sheet at the bottom of UV tin graphed sheet.At the bottom of UV tin graphed sheet, main body of oil adopts two functional group's epoxy acrylates, trifunctional polyurethane-acrylate, non-response type organosiloxane levelling agent (BYK333), light trigger, does not therefore contain volatile solvent, has 100% solid content.
Gloss oil coating layer adopts UV metal decorating gloss oil coating layer to replace heat curing-type gloss oil coating layer.UV metal decorating gloss oil coating layer uses UV metal decorating gloss oil.The main component of UV metal decorating gloss oil adopts two functional group's epoxy acrylates, trifunctional polyurethane-acrylate, non-response type organosiloxane levelling agent (BYK333), light trigger and filler.
Owing to thering is good adhesive force between two functional group's epoxy acrylates and printable fabric, and there is good pliability, therefore at the bottom of UV tin graphed sheet, oil coating layer can be used in the adhesive force of strengthening UV film and printable fabric top layer, and has the good matching of adhering to ink coating layer.Trifunctional polyurethane-acrylate has the performance that improves solidification effect and resistance to xanthochromia.
Non-response type organosiloxane levelling agent (BYK333) is as auxiliary agent, the levelling of oil and UV metal decorating gloss oil at the bottom of auxiliary UV tin graphed sheet.
Filler is mainly wax slurry, can improve scratch resistance and the endurance energy of gloss oil.Therefore, UV metal decorating gloss oil coating layer has good flexibility, processability, for improving the wearability of cured coating film, anti-scratch trace, the transparency and light transmission.
Ink coating layer can be UV tin printing ink coating layer.Printable fabric top layer can be zinc-plated tinplate top layer.
The beneficial effects of the utility model are:
1, environmental pollution is low: at the bottom of UV tin graphed sheet, oil and UV metal decorating gloss oil do not contain volatile solvent, there is 100% solid content, in UV tin graphed sheet technical process, can not produce large quantity of exhaust gas, environmentally safe, the coating of environmental protection and energy saving, and pliability is good, adhesive force is good, good impact resistance, good, the non-migratory property of boiling resistance, can adapt to the needs of processing after metal.Under identical technique, use the thickness of oil coating layer at the bottom of UV tin graphed sheet be only at the bottom of heat curing-type oily coating layer 1/3rd, the thickness of UV metal decorating gloss oil coating layer is only 1/2nd of heat curing-type gloss oil coating layer.
2, save time controlled, save energy consumption: due to oil and UV metal decorating gloss oil at the bottom of UV tin graphed sheet be can film-forming under ultraviolet light conditions macromolecular material, UV light solid owner will provide energy by ultraviolet lamp, can open as required and close down UV lamp, realize and be interrupted printing, only need just can provide for 2 minutes curing institute energy requirement; UV solidifies and can watch fast and control, and immediately sees result, controls rapidly product quality well, the rate of reducing the number of rejects and seconds; UV curing apparatus power consumption approximates traditional drying room operation power consumption, therefore compares the technique of heat curing-type, can save a large amount of fuel and significantly reduce equipment maintenance cost, is conducive to low-carbon environment-friendly.
3, equipment etc. drops into less, efficiency is higher: the curing corresponding application of UV and curing apparatus are fairly simple, maintenance is easy and expense is low, and the length of UV lamp and relevant apparatus is 3 meters of left and right, is about 1/10th of traditional drying room, floor space is little, be applicable to working continuously, equipment easily manipulates, and operating personnel are few, maintenance of equipment and the minimizing in a large number between the stopping time of having a rest, production efficiency is higher.
