Further, the flexibility of the base material layer 11 is greater than that of the defoaming layer 13. Of course, in another embodiment, the base material layer 11 may have fluidity equivalent to that of the defoaming layer 13.

It can be understood that when the defoaming layer 13 wraps up foreign matters such as oil stains, dust, fingerprints, etc., the portion of the substrate layer 11 corresponding to the wrapped position may slightly bulge, and at this time, because the substrate layer 11 has a certain flexibility, the substrate layer 11 at the position corresponding to the bulged position in the defoaming layer 13 can be kept flat, and the flatness of the whole protective film can be effectively ensured.

Further, the OCA glue layer 12 may be made of OCA glue. Of course, in other embodiments, the OCA glue layer 12 may be replaced by a layer made of other materials, and is not limited herein.

In the present embodiment, the thickness of the base layer 11 is in the range of 48um to 52um, the thickness of the oca adhesive layer 12 is in the range of 37um to 43um, and the thickness of the defoaming layer 13 is in the range of 37um to 43um.

Compared with the prior art, the utility model provides an including the defoaming layer 13 that possesses the defoaming function in the AB glue film 10, when pasting the protection film and establishing on electronic equipment's screen, defoaming layer 13 and screen direct contact can the quick defoaming at the in-process of pad pasting to in-process at the pad pasting can not the gassing.

Referring to fig. 2, the present invention further provides a protective film 100 with a defoaming function, where the protective film 100 may be, but not limited to, a soft film or a hard film, and in this embodiment, the protective film 100 is taken as an example for description.

The protection film 100 comprises a protection layer 30 and the AB glue layer 10, wherein the protection layer 30 is attached to the OCA glue layer 12 in the AB glue layer 10. The structure of the AB glue layer 10 is the same as the structure of the AB glue layer 10, and is not described herein again.

In the present embodiment, the protective layer 30 is a glass layer, and the thickness of the protective layer 30 is in the range of 0.05mm to 0.85mm.

Further, the protection film 100 further comprises a first release layer 40, the first release layer 40 is attached to the surface of the defoaming layer 13 departing from the substrate layer 11, and the thickness range of the first release layer 40 is 48um to 52um.

It can be understood that, through the surface subsides that deviate from substrate layer 11 at defoaming layer 13 establishes a first from type layer 40, can protect defoaming layer 13 in AB glue film 10, before the pad pasting, tear first from type layer 40 and just can paste this defoaming layer 13 and establish on electronic equipment's the screen.

Compared with the prior art, the utility model provides a protection film 100 has the aforesaid AB glue film 10, including the defoaming layer 13 that possesses the defoaming function in this AB glue film 10, when pasting protection film 100 and establishing on electronic equipment's screen, defoaming layer 13 and screen direct contact can the quick defoaming at the in-process of pad pasting to in-process at the pad pasting can not produce the bubble.

In addition, if the size of the foreign matter remaining on the screen of the electronic device is large, the protective film 100 may be attached to the screen of the electronic device again by separating the protective film 100 from the screen of the electronic device, and then cleaning the foreign matter. The protection film 100 provided in this embodiment not only has the defoaming function, but also the special fluidity of the defoaming layer makes it compare with current protection film, can paste repeatedly and use, in the in-process with protection film 100 and electronic equipment screen separation, even the defoaming layer surface is stained with foreign matters such as dust, can not influence the laminating once more of protection film 100 and electronic equipment screen.

The utility model also provides a protection film suit, this protection film suit include repair sticker 50 (please refer to fig. 3) and the aforesaid protection film 100, repair sticker 50 include body 51 and locate the restoration layer 52 on body 51 surface, and restoration layer 52 is used for pasting on the defoaming layer 13 of protection film 100 to restore defoaming layer 13 of protection film 100.

Further, the repair layer 52 has a larger viscosity than the defoaming layer 13.

It can be understood that, in the case where the adhesiveness of the repair layer 52 is greater than that of the defoaming layer 13, the repair layer 52 is also used to be stuck on the defoaming layer to replace foreign matters stuck on the defoaming layer, thereby repairing the defoaming layer 13 and effectively prolonging the service life of the protective film 100.

In this embodiment, the material of the repair layer comprises the following components mixed in weight ratio: 28 to 35 percent of methyl vinyl, 55 to 65 percent of ethyl ester, 8 to 12 percent of dimethylbenzene and 1.5 to 2.5 percent of ethyl benzene.

Further, the repair sticker 50 further includes a second release layer 53, and the second release layer 53 is attached to the repair layer 52.

It can be understood that, by disposing the second release layer 53 on the repair layer 52, the second release layer 53 can be protected, and when repairing the defoaming layer 13, only the second release layer 53 on the repair layer 52 needs to be torn off.

Of course, referring to fig. 4, in other embodiments, the repair sticker 50 includes a plurality of second release layers 53, and the plurality of second release layers 53 are arranged on the repair layer 52.

It can be understood that by providing a plurality of second release layers 53 on the repair sticker 50, a user can selectively tear off a desired amount of the second release layers 53 as desired.

Of course, in other embodiments, the user may temporarily attach the protective film 100 to the repair layer 52 without using the protective film 100, and attach the protective film 100 to the screen of the electronic device again when the user needs to use the protective film.

Compared with the prior art, the AB glue layer 10 of the protective film set 200 provided by the embodiment includes the defoaming layer 13 with a defoaming function, when the protective film 100 is attached to the screen of the electronic device, the defoaming layer 13 is in direct contact with the screen of the electronic device, and defoaming can be performed rapidly in the process of attaching the protective film, so that no bubble is generated in the process of attaching the protective film. In addition, the repair layer 52 can repair the defoaming layer 13, and the repair process includes the following two ways: firstly, because the viscosity of the repairing layer 52 is greater than that of the defoaming layer 13, when the repairing layer 52 is attached to the surface of the defoaming layer 13, the repairing layer 52 can replace foreign matters such as dust and the like adhered to the surface of the defoaming layer 13, so that the surface of the defoaming layer is cleaner; secondly, because the surface of defoaming layer 13 is stuck with foreign matters, the unevenness of the surface of the defoaming layer can be caused, and the unevenness of the surface of the defoaming layer can be repaired by the fluidity of the repairing layer 52 and the fluidity of the defoaming layer by sticking the repairing layer on the defoaming layer 13, so that the protective film 100 can be repeatedly used, and the utilization rate of the protective film is improved.

The film sticking effect of the protective film 100 of the present invention will be described below.

Fig. 5 to 10 are photographs of a screen of an electronic device before film attachment, fig. 11 to 13 are diagrams illustrating an effect of attaching the protective film 100 to the screen of the electronic device, and fig. 14 to 18 are diagrams illustrating an effect of attaching the conventional protective film to the screen of the electronic device.
