Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0023] See also Figure 1-4 The utility model provides a reusable screen protective film with good adhesion, which is characterized in that a groove 2 is opened on the outer side of the bottom surface of the computer film body 1, an adhesive layer 3 is adhesively connected in the groove 2, and the bottom surface of the adhesive layer 3 is on the same plane as the bottom surface of the computer film body 1.

[0024] It is worth mentioning that compared with the traditional frame-type laminating computer film, the utility model adopts a process structure in which the adhesion layer 3 is flush with the bottom surface of the computer film body 1, avoiding the gap between the computer film and the screen, affecting the sensitivity of the touch screen, and at the same time improving the display effect.

[0025] Furthermore, the attachment layer 3 is water-washable glue.

[0026] Specifically, washable glue is a new type of synthetic glue that can be used repeatedly without leaving any residue. It can also be cleaned with water when it is not sticky. One side is a fixed glue on the PET substrate, and the other side is a washable product.

[0027] Furthermore, a groove 2 is provided on the outer periphery of the bottom surface of the computer film body 1 .

[0028] Furthermore, the computer film body 1 includes a PET base layer 11, a first photocurable layer 12 is provided on the top of the PET base layer 11, an anti-peeping layer 13 is provided on the top of the photocurable layer 12, a second photocurable layer 121 is provided on the top of the anti-peeping layer 13, a frosted layer 14 is provided on the top of the second photocurable layer 121, and a protective film 15 is provided on the top of the frosted layer 14.

[0029] It is worth mentioning that it adopts 3H hardening treatment, which has higher hardness and anti-scratch function. It is made by special compound process, which greatly improves the anti-peeping effect and touch.

[0030] Furthermore, a release film 4 is bonded and connected to the bottom of the computer film body 1 . Example

[0031] This embodiment also includes: the attachment layer 3 is a magnetic strip.

[0037] Furthermore, grooves 2 are provided at four corners of the bottom surface of the computer film body 1 .

[0038] The working principle of a reusable screen protection film with good adhesion based on the above embodiment is: a groove 2 is opened on the outer side of the bottom surface of the computer film main body 1, and the groove 2 is divided into two different opening structures: full frame and four corners. There is an adhesion layer 3 in the groove 2, and the adhesion layer 3 is flush with the bottom plane of the computer film main body 1, so that the computer film main body 1 and the screen are more closely fitted to avoid gaps. The adhesion layer 3 is made of two different materials: water-washable glue and magnetic strip. The bottom release film 4 is torn off and adhered to the display screen by bonding or magnetic attraction, and can be reused. The computer film main body 1 adopts 3H hardening treatment, which has higher hardness and anti-scratch function. At the same time, the anti-peeping layer 13 and the frosted layer 14 are added and compounded by special process, and the anti-peeping and anti-diffuse light effects are greatly improved.
