preparation example Construction

[0059] The present invention also provides a method for preparing an anti-peep printable antimagnetic film, comprising the following steps:

[0060] A) one side of the substrate layer is coated with a micro-blind structure layer to obtain a substrate layer compounded with a micro-blind structure layer;

[0061] B) one side of the TPU film is coated with a UV hardening layer to obtain a TPU layer with a UV hardening layer;

[0062] C) OCA glue is coated on the other side of the base material layer, and the TPU layer with the UV hardening layer is bonded, and after curing, an OCA glue layer is obtained;

[0063] D) attaching a first protective film layer on the surface of the UV hardening layer, and attaching a second protective film layer on the surface of the micro-louver structure layer to obtain an anti-peeping printable antimagnetic film.

[0064] In the present invention, the micro-louver structure layer is first coated on one side of the base material layer to obtain the...

Embodiment 1

[0077] 1. On one side of a 50 μm PET film (substrate), a 25 μm micro-louver structure layer is coated with a doctor blade to obtain a PET film layer compounded with a micro-louver structure layer.

[0078] 2. With 12 parts by weight of silver powder and iron oxide, 6 parts by weight of carbon fiber, 45 parts by weight of hexanediol diacrylate, 25 parts by weight of epoxy acrylic resin, 80 parts by weight of toluene, 2 parts by weight of photoinitiated Agent (the mass ratio of benzophenone and triethanolamine is 2:1) was stirred and mixed for 5 minutes, dried in an oven at 90°C for 75 seconds, and then dried at 300-550mJ / cm 2 Under curing, a UV hardened layer with a thickness of 4 μm was obtained.

[0079] 3. On one side of the 100 μm TPU film, apply the above-mentioned UV curable layer by dimple coating to obtain a TPU layer with a UV curable layer.

[0080] 4. On the other side of the 50 μm PET film, apply a 30 μm OCA glue by means of drop glue coating, stick it with the TPU...

Abstract

The invention provides a peep-proof printable magnetic-resistant film. The peep-proof printable magnetic-resistant film comprises a first protective film layer, an UV hardened layer composited to the first protective layer, a TPU layer composited on the UV hardened layer, an OCA adhesive layer composited on the TPU layer, a substrate layer combined on the OCA adhesive layer, a micro louver structure layer composited on the substrate layer and a second protective layer combined to the micro louver structure layer. The UV hardened layer is made of metal and oxide thereof, carbon conductive material and UV varnish glue. The UV hardened layer has an anti-magnetic effect and a printable function, the UV-hardened layer cooperates with the other layers to obtain the peep-proof printable magnetic-resistant film which has display confidentiality, the peep-proof layer is effectively prevented from being scratched, and the film has good printability and magnetic resistance and can meet customer's personal pursuit.

Description

technical field [0001] The invention relates to the field of protective film manufacture, in particular to a peep-proof printable antimagnetic film and a preparation method thereof. Background technique [0002] Tempered glass protective film is a new type of screen protective film for electronic products. Because of its high hardness and low toughness, it can well prevent broken screens and is at the highest level of electronic product screen safety protection. At present, the tempered glass protective films appearing on the market have relatively single functions and cannot meet the daily needs of customers. Contents of the invention [0003] In view of this, the technical problem to be solved by the present invention is to provide an anti-peeping printable antimagnetic film and its preparation method. The anti-peeping printable antimagnetic film provided by the present invention not only has the confidentiality of the display screen, but also can effectively avoid Scra...
