Abstract: The present disclosure discloses a composite light-curing protective film and a film sticking method and use thereof. The composite light-curing protective film includes a base film layer that provides support, a light-curing functional layer to be light-cured, and an adhesive layer, and the base film layer, the light-curing functional layer, and the adhesive layer are laminated in sequence to form a sandwich structure. The composite light-curing protective film of the present disclosure is stuck to the surface of the film to be stuck, and the light-curing functional layer is cured after the light-curing treatment to form a protective film layer that completely matches the surface shape of the film to be stuck, and the sticking stability can be ensured, without the problems of bounce-back and the difficulty of sticking, and also the protective film layer will not have the problems of bounce-back and the difficulty of sticking.

Abstract: The present application belongs to the technical field of manufacture for protection film for a terminal curved surface, and relates to a protection film for a terminal curved surface and manufacture method thereof, the hardened layers is provided on both sides of the substrate layer, and the substrate layer and the two hardened layers form the original sheet. The original sheet is hot-pressed by a hot pressing device, and the upper mold and the lower mold clamping the original sheet are heated, pressurized and cooled in order to obtain a protection film for a terminal curved surface, and the mold core outer rounded corner combining with the mold cavity inner rounded corner are pressurized to form a curved surface portion. The hardened layers is disposed on both sides of the substrate layer, so that the stress on both sides of the substrate layer are cancel each other after the substrate layer is heated, and the terminal surface protective film is more flat.

Abstract: A method for applying a screen protector to a cell phone screen protector is provided, including: providing a cell phone screen protector and a cell phone to be applied; cleaning a screen of the cell phone to be applied; tearing off the release liner by the label of the release liner, simultaneously lightening the screen of the cell phone to be applied, and sticking the silicone protective film on the screen, and uncovering the first part via the label of the first part; using a scraping card to scrape slightly from top to bottom; uncovering the second part via the label of the second part, and using the scraping card to scrape slightly from top to bottom; using the scraping card to scrape outwardly along a curved edge of the screen; tearing off the PET release film, and smoothing both sides of the screen.
