Description

Technical Field

[0001] The utility model relates to the technical field of peeling films, in particular to a peeling film for an AF display screen. Background Art

[0002] AF display screen is a dust and oil-proof screen. The surface energy of the display screen is low, so it has hydrophobic and oleophobic properties. Therefore, its surface wetting performance is low, and it will not adhere to the surface of other materials. It is not easy to be polluted and can be recycled. The impurities and dirt remaining on the surface can also be easily wiped off to keep the surface smooth and tidy. Due to its superior isolation effect, this type of screen is widely used in various display devices, especially electronic products with touch operation requirements. The actual peeling force of the glue for AF display screen protective film on the market is only 5 to 20gf peeling force, and foreign products can only reach 10 to 30gf peeling force at most, which still does not meet the use requirements. Especially for the curved AF display screen, not only high peeling force but also good initial adhesion are required. For this reason, a layer of film with peeling function needs to be attached to the surface of the AF display screen as a protective effect.

[0003] The invention patent with publication number "CN112961613A" and titled "An adhesive for AF display screen protective film, its preparation method and protective film" discloses an adhesive for AF display screen protective film, its preparation method and protective film. The acrylic resin is prepared by a photo-initiated method, applied to a TPU substrate by a coater, and then a release film is attached. The photocured film is obtained by irradiation and curing with an ultraviolet light source. Although the prepared AF display screen protective film achieves a high and stable peeling force, it is easy to be contaminated by dust and particles due to electrostatic adsorption when attached to the AF screen in order to have an antistatic function. If dust is adsorbed on the adhesive surface, its initial adhesion will be affected. In addition, during the use or debugging of the AF display screen, it is easy to generate light radiation or conduction, and it is also easy to be squeezed or hit by hard objects. For this reason, it is necessary to develop a peeling film with antistatic, shielding and impact resistance to match the application requirements of the AF display screen. Utility Model Content
