DETAILED DESCRIPTION

[0027] The technical scheme of the utility model will be further explained below in combination with the drawings and specific embodiments.

[0028] Embodiments, as Figures 1 to 6 shown, the utility model provides a kind of high-strength flexible protective film, including the base layer 1, hardening layer 4, top layer 5 and release layer 6 that are sequentially laminated, another side of base layer 1 is equipped with adhesive layer 2, adhesive layer 2 is equipped with release layer 3, base layer 1 is usually made of PET or PC etc. high molecular material, base layer 1 provides the basic strength, dimensional stability and shape of film, base layer 1 is the basic layer of entire protective film, other layers are directly coated or adhered on it. Adhesive layer 2 can be acrylic, silicone or other types of adhesive, adhesive layer 2 enables protective film to be firmly attached on the surface needing protection. Adhesive layer 2 is applied to base layer 1 by coating process, and is cured by curing treatment. Release layer 3 is made of specially treated paper or plastic film, and surface is coated with silicone oil or other low-adhesion substances. The purpose of release layer 3 is to protect adhesive layer 2 during protective film production and transportation, prevent it from contacting and contaminating other surfaces. Hardening layer 4 is usually silicone, acrylic or other hard coating materials. Adhesive layer 2 provides scratch resistance, wear resistance and impact resistance. Top layer 5 is special coating material, such as anti-fingerprint coating, anti-glare coating or hydrophobic and oleophobic coating. Top layer 5 provides additional protection, such as stain resistance, fingerprint resistance, improved transparency or improved hand feeling. Release layer 6 is a specially designed paper or plastic film, coated with silicone oil or other low-adhesion substances. Release layer 6 protects top layer 5 from contamination before use of protective film, and facilitates peeling during installation.

[0029] The embodiment further comprises a positioning member mounted on the release layer 6, which pastes the base layer 1 on the protection member. The positioning member comprises a positioning sticker 7 provided on the release layer 6, and the positioning sticker 7 is provided with an adhesive layer 8. The adhesive layer 8 is provided with a protection layer 9, and the protection layer 9 is longer than the positioning sticker 7. The protection layer 9 can be conveniently torn off from the positioning sticker 7. The protection layer 9 can prevent the adhesive layer 8 from being contaminated during transportation and storage. When the protection film is installed, the protection layer 9 is torn off, and the positioning sticker 7 is pasted on the protected surface through the adhesive layer 8. The position of the base layer 1 is adjusted to align the base layer 1 with the protected surface. The precision during pasting of the film is effectively increased, and the phenomenon of pasting the protection film crookedly is effectively reduced.

[0030] The embodiment further comprises a traction module fixedly connected to one end of the release layer 3, which separates the release layer 3 from the base layer 1. The traction module comprises a traction film 10 fixedly installed on the release layer 3. The release layer 3 is provided with a first protruding portion 11 protruding from the base layer 1, and the traction film 10 is fixedly connected to the first protruding portion 11. After the base layer 1 is pasted on the protected surface through the positioning sticker 7, the release layer 3 can be torn off, so that the adhesive layer 2 is in contact with the protected surface and the base layer 1 is pasted on the protected surface through the adhesive layer 2. The first protruding portion 11 is flipped upward by pulling the traction film 10, and the release layer 3 is moved upward. The release layer 3 can be torn off. The release layer 3 is torn off after the base layer 1 is positioned, so that the adhesive layer 2 is not in contact with the protected surface when the base layer 1 is positioned, the positioning is not difficult, and the adhesive layer 2 is not damaged during positioning.

[0031] The release layer 6 is provided with a counterforce module, which moves synchronously with the traction module and balances the stress condition on both sides of the base layer 1. When the release layer 3 is torn off, the base layer 1 is bent in the direction of the release layer 3 due to the certain bonding force between the base layer 1 and the release layer 3, which easily causes the base layer 1 to bend and the adhesive layer 2 to be misaligned with the protected surface. The counterforce module comprises a counterforce film 13 attached to the release layer 6, and the counterforce film 13 is attached to the release layer 6 through a glue layer 12. The counterforce film 13 is fixedly installed with a traction film 15. The counterforce film 13 is provided with a second protruding portion 14 protruding from the release layer 6, and the traction film 15 is fixedly installed on the second protruding portion 14. When the release layer 3 is torn off, the counterforce film 13 is torn off synchronously, and the counterforce film 13 applies a force to the base layer 1 in the direction of the counterforce film 13, which counteracts the pulling force of the release layer 3 on the base layer 1, so that the base layer 1 does not bend when the release layer 3 is torn off.

[0032] Further, the pulling film 15 and the traction film 10 are fixedly installed with a pull plate 16, and the pull plate 16 is fixedly installed with a pull handle 17. The pull handle 17 is pulled to drive the pull plate 16 to move, the pulling film 15 and the traction film 10 are driven to move synchronously through the pull plate 16, and then the off-shape layer 3 and the counterforce film 13 can be synchronously torn off. After the off-shape layer 3 and the counterforce film 13 are torn off, the release layer 6 is pressed to adhere the base layer 1 to the protected surface through the adhesive layer 2, then the positioning sticker 7 is torn off to drive the release layer 6 to separate from the top layer 5, and the installation of the protective film is completed.

[0033] The working principle of the embodiment is as follows: when the protective film is installed, the positioning sticker 7 is adhered to the protected surface through the adhesive layer 8 by tearing off the protective layer 9, and the position of the base layer 1 is adjusted to align the base layer 1 with the protected surface. The precision during the film pasting can be effectively increased, and the phenomenon of the protective film pasting skew can be effectively reduced. The pull handle 17 is pulled to drive the pull plate 16 to move, the pulling film 15 and the traction film 10 are driven to move synchronously through the pull plate 16, and then the off-shape layer 3 and the counterforce film 13 can be synchronously torn off. When the off-shape layer 3 is torn off, the counterforce film 13 is synchronously torn off, the base layer 1 is subjected to the force of the counterforce film 13 in the direction towards the counterforce film 13, the pulling force of the off-shape layer 3 on the base layer 1 can be offset, and then the base layer 1 will not be bent when the off-shape layer 3 is torn off. After the off-shape layer 3 and the counterforce film 13 are torn off, the release layer 6 is pressed to adhere the base layer 1 to the protected surface through the adhesive layer 2, then the positioning sticker 7 is torn off to drive the release layer 6 to separate from the top layer 5, and the installation of the protective film is completed.

[0034] The above specific embodiments are only several optional embodiments of the utility model, based on the technical scheme of the utility model and the related inspiration of the above embodiments, the person skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
