Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of membrane material, especially a screen film. BACKGROUND

[0002] The current market mobile phone film can be divided into two categories: PET substrate plastic film and tempered glass film. The mobile phone plastic film structure is generally three layers of PET protective film: one layer of release film, one layer of PET protective film and one layer of release film. Only the middle PET protective film is mainly pasted on the mobile phone screen. The outer release film is used to prevent the PET film from being dusty and to protect the PET film. The double-layer PET film is less than one layer of release film. The tempered glass film is generally composed of four layers. The first layer is a special coating; the second layer is tempered glass; the third layer is an explosion-proof film; and the fourth layer is a silicone rubber coating.

[0003] However, the above two kinds of mobile phone films can only guarantee the wear resistance and adsorption of the film (the adhesion performance of the mobile phone screen), but the hydrophobicity, anti-fouling, anti-scratching, ultraviolet resistance and weather resistance of the film still need to be improved. INVENTION CONTENTS

[0004] The utility model aims at solving the above problems and provides a screen film with excellent hydrophobicity, anti-fouling, anti-scratching, ultraviolet resistance and weather resistance.

[0005] To achieve the above purpose, the utility model provides a screen film, which comprises a surface layer, a first base layer and an adhesive layer which are stacked in sequence, wherein the surface layer comprises at least one of VMQ silicone resin and MQ silicone resin, and the first base layer is a PET layer or a TPU layer.

[0006] In the utility model, the VMQ silicone resin layer and the MQ silicone resin layer as the outermost layer of the screen film can improve the hydrophobicity, transparency and touch feeling of the screen film, and the PET layer or the TPU layer as the inner layer can improve the toughness of the screen film.

[0007] In the screen film, the adhesive layer can be an OCA glue coating, an acrylic glue coating or a silicone rubber coating. In this case, the OCA glue (Optically Clear Adhesive) is a glue structure with high transparency, high refractive index, no bubbles and no defects. The acrylic glue and the silicone rubber also have excellent transparency. Therefore, when the adhesive layer is an OCA glue coating or a silicone rubber coating, the adhesion performance with the screen can be improved while the transparency of the adhesive layer is ensured.

[0008] Optionally, the screen protector of this invention may also include a privacy layer disposed between the first base layer and the adhesive layer. The privacy layer can be manufactured using ultra-fine venetian blind optical technology. By controlling the angle of light propagation, the privacy layer can narrow the screen's viewing angle, ensuring that the content is only visible within a certain angle range from the front; outside this range, the screen content cannot be seen by others, thus achieving a privacy protection effect.

[0009] Optionally, the screen protector of this invention may also include a second base layer, with the privacy layer disposed between the first and second base layers. In this case, by placing the privacy layer in the interlayer formed by the first and second base layers, the protection of the privacy layer can be improved, and by including both the first and second base layers, the structural strength of the screen protector can be enhanced.

[0010] Optionally, the screen protector of this invention may also include a first release layer, which is disposed on the side of the surface layer away from the first base layer. Thus, the first release layer can serve as a protective film, providing dust protection and other functions.

[0011] Optionally, the screen film of this invention may also include a second release layer, which is disposed on the side of the adhesive layer away from the first base layer. Thus, the second release layer can serve as a substrate, facilitating the formation of the adhesive layer, the first base layer, and the surface layer thereon.

[0012] In the screen protector of this invention, optionally, the surface layer, the first base layer, and the adhesive layer are transparent. This improves the light transmittance of the screen protector, making it easier for users to see the images on the screen.

[0013] In the screen protector of this invention, optionally, an adhesive is applied between the surface layer and the first base layer. In this case, the adhesive enhances the bond between the surface layer and the first base layer, reducing the likelihood of the surface layer and the first base layer detaching.

[0014] In the screen protector of this invention, optionally, the silicone in the surface layer is organic silicone. In this case, organic silicone has advantages over ordinary silicone, such as anti-fouling, high and low temperature resistance, weather resistance, hydrophobicity, and antibacterial properties. When the surface layer is made of organic silicone, the screen protector can have good anti-fouling, high and low temperature resistance, weather resistance, hydrophobicity, and antibacterial properties.

[0015] In the screen film, optionally, the surface layer is a silicon rubber layer, a VMQ silicone resin layer, an MQ silicone resin layer, or a mixed layer made of any two or three of the silicon rubber, the VMQ silicone resin and the MQ silicone resin.

[0016] In the screen film, optionally, the silicon rubber layer is made of liquid silicon rubber, and the liquid silicon rubber is added with a hydrophobic agent, a scratch-resistant agent, an ultraviolet-resistant agent and a weather-resistant agent.

[0017] In the screen film, optionally, a self-repairing coating is further included, and the self-repairing coating is arranged on the side of the surface layer away from the first base layer.

[0018] In the screen film, optionally, the surface layer is added with at least one of a mildew-proof agent and an antibacterial agent.

[0019] According to the screen film, good toughness and wear resistance, anti-fouling, hydrophobic, scratch-resistant, ultraviolet-resistant and weather-resistant properties can be provided. BRIEF DESCRIPTION OF DRAWINGS

[0045] In some embodiments, the silicon rubber layer can have one or more layers. For example, the silicon rubber layer can have 1 to 10 layers. In this case, the thickness of the screen film can be controlled by increasing or decreasing the number of layers of the silicon rubber layer according to the user's needs.

[0046] In some embodiments, when the silicon rubber layer 30 has multiple layers, each layer of the silicon rubber layer can have a thickness of 10 to 50 micrometers.
