s3): compounding: carrying out high-temperature pressing on the roll A of the gloss oil coated surface and the roll B of the original binding surface;
s4): curing in an inner printing process: placing the compounded film into a curing box for curing, and adopting an inner printing process; after the curing is finished, the strength between films of the film is obviously improved, and all technical requirements and customer use requirements of the casing film can be completely met.
Further, the gloss oil used in step S2 is an environment-friendly UV gloss oil, and the gloss oil comprises the following components: 25-30 parts of ultraviolet photosensitive resin, 5-8 parts of photoinitiator, 8-20 parts of active monomer and 3-5 parts of auxiliary solvent.
Furthermore, the thickness of the roll A coated with the original laminating gloss oil is controlled to be 2 microns.
Further, in the process of cutting the original film by the cutting machine in the step S1, the original film is firstly soaked in hot water at 70-80 ℃ for 10-15 minutes, and the cut A, B rolls of raw materials are respectively sent to an air heater for air drying.
Further, the step S2 gloss oil applying process is performed in a dark box.
Further, the high-temperature pressing in the step S3 is performed in four stages, the surface temperature of the first section of control pressing roller is 100 to 120 ℃, the surface temperature of the second section of control pressing roller is 120 to 140 ℃, the surface temperature of the third section of control pressing roller is 140 to 180 ℃, and the surface temperature of the fourth section of control pressing roller is 180 to 220 ℃.
Further, in the step S4, the temperature of the curing box is controlled to be 180-220 ℃, and curing is carried out for 20-30 minutes.
Compared with the prior art, the invention has the beneficial effects that: the invention can effectively improve the strength between films, enables the performance of the films to meet the requirement of long-time storage, and simultaneously can solve the problem that the performance of the existing printed films is reduced and only can be scrapped due to long-time storage; after the film is cured, the strength between films of the film is obviously improved, and various technical requirements and customer use requirements of the casing film can be completely met.
