Description

Technical Field

[0001] This utility model relates to the field of mobile phone film technology, and in particular to a mobile phone film that prevents fingerprints. Background Technology

[0002] Mobile phone screen protectors, also known as mobile phone beautification films or mobile phone protective films, are cold-laminated films used to cover the surface of mobile phone bodies, screens, and other tangible objects. There are many types, which can be divided into mobile phone screen protectors and mobile phone body protectors according to their uses. Their functions have evolved from the initial simple anti-scratch protective films to the introduction of functional protective film series, which can be divided into: privacy films, mirror films, AR films, matte films, high-definition films, anti-scratch protective films, 3D films, mobile phone body anti-scratch protective films, diamond films, and tempered glass films, etc.

[0003] With the widespread use of smartphones, screen protectors have become an indispensable accessory for daily mobile phone use. However, existing screen protectors are prone to fingerprints, smudges, and other contaminants when touched by the user's fingers. This not only affects the aesthetics of the screen but may also interfere with the display and reduce the user experience. To address these issues, we propose a fingerprint-resistant screen protector. Utility Model Content

[0004] The purpose of this invention is to provide a fingerprint-resistant mobile phone screen protector to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fingerprint-resistant mobile phone screen protector includes a screen protector body. Release paper is fixedly connected to both the upper and lower surfaces of the screen protector body. Two protective strips are fixedly connected to the lower surface of one of the release paper strips. The bottom end of each protective strip contacts the upper surface of one of the release paper strips. The screen protector body includes an anti-fingerprint coating. Nanomaterials are disposed above the anti-fingerprint coating, and a wear-resistant layer is disposed above the nanomaterials.

[0007] In a further embodiment, each of the two release papers has a peeling tab at both ends, and the two peeling tabs are fixedly connected to the left and right ends of the release paper respectively on the side that is close to each other.

[0008] In a further embodiment, the main body of the mobile phone film includes a first explosion-proof layer, a base film layer is provided above the first explosion-proof layer, a base film layer is provided above the base film layer, a second explosion-proof layer is provided above the base film layer, and a waterproof layer is provided on the upper surface of the second explosion-proof layer.

[0009] In a further embodiment, the upper surface of the first explosion-proof layer is bonded to the bottom surface of the base film layer with OCA optical adhesive, the upper surface of the base film layer and the bottom surface of the second explosion-proof layer are bonded together with OCA optical adhesive, and the upper surface of the second explosion-proof layer and the bottom surface of the waterproof layer are bonded together with OCA optical adhesive.

[0010] In a further embodiment, the upper surface of the anti-fingerprint coating is bonded to the bottom surface of the nanomaterial using OCA optical adhesive, the upper surface of the nanomaterial is bonded to the bottom surface of the wear-resistant layer using OCA optical adhesive, and the upper surface of the waterproof layer is bonded to the bottom surface of the anti-fingerprint coating using OCA optical adhesive.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This device uses OCA optical adhesive to bond a first explosion-proof layer, a base film layer, a second explosion-proof layer, and a waterproof layer. This ensures both explosion-proof performance and maintains the light transmittance of the main body of the screen protector. Through the inclusion of an anti-fingerprint coating combined with the oleophobic and abrasion-resistant properties of nanomaterials and a wear-resistant layer, the nanomaterials are one or more of silicon dioxide, titanium dioxide, or aluminum oxide. The nanomaterials have good dispersibility and surface activity, and can form a uniform microstructure in the anti-fingerprint coating, thereby improving the anti-fingerprint and abrasion-resistant performance of the coating. This achieves the functions of anti-fingerprint, explosion-proof, and abrasion-resistant, raising the industry standard for screen protectors to a new level. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 In this utility model, a fingerprint-resistant mobile phone screen protector includes a screen protector body 1. Release paper 2 is fixedly connected to both the upper and lower surfaces of the screen protector body 1. Two protective strips 4 are fixedly connected to the lower surface of one of the release paper 2. The bottom end of each protective strip 4 is in contact with the upper surface of one of the release paper 2. The screen protector body 1 includes an anti-fingerprint coating 105. A nanomaterial 106 is provided above the anti-fingerprint coating 105. A wear-resistant layer 107 is provided above the nanomaterial 106.

[0022] Each of the two release papers 2 has a peeling tab 3 at both ends. The two peeling tabs 3 are fixedly connected to the left and right ends of the release paper 2 respectively. The peeling tabs 3 facilitate the separation of the release paper 2 from the mobile phone film body 1. The mobile phone film body 1 includes a first explosion-proof layer 101. A base film layer 102 is provided above the first explosion-proof layer 101. A second explosion-proof layer 103 is provided above the base film layer 102. A waterproof layer 104 is provided on the upper surface of the second explosion-proof layer 103. The combination of the first explosion-proof layer 101, the second explosion-proof layer 103 and the waterproof layer 104 can improve the protective performance of the mobile phone film body 1.

[0023] The upper surface of the first explosion-proof layer 101 is bonded to the bottom surface of the base film layer 102 using OCA optical adhesive. The upper surface of the base film layer 102 is bonded to the bottom surface of the second explosion-proof layer 103 using OCA optical adhesive. The upper surface of the second explosion-proof layer 103 is bonded to the bottom surface of the waterproof layer 104 using OCA optical adhesive. Since the base film layer 102 is a transparent polymer film with good flexibility and light transmittance, it can provide basic physical support and protection for the main body of the mobile phone film 1. The anti-fingerprint coating 105 is applied to the surface of the base film layer 102 and is composed of nanomaterials 106 and an anti-fingerprint agent, effectively preventing fingerprints. The upper surface of the anti-fingerprint coating 105 is bonded to the bottom surface of the nanomaterials 106. The upper surface of the nanomaterial 106 and the bottom surface of the wear-resistant layer 107 are bonded together using OCA optical adhesive. The upper surface of the waterproof layer 104 and the bottom surface of the anti-fingerprint coating 105 are also bonded together using OCA optical adhesive. The thickness of the anti-fingerprint coating 105 is 1-5μm, preferably 3μm. This thickness range ensures that the coating has a good anti-fingerprint effect, while not affecting the light transmittance or increasing the overall thickness of the screen protector due to excessive thickness. The thickness of the base film layer 102 is 0.1-0.3mm, preferably 0.2mm. This thickness range ensures the flexibility of the screen protector body 1, allowing it to adapt to different shaped screens, while not affecting the appearance and feel of the phone due to excessive thickness.

[0024] The working principle of this utility model is as follows:

[0025] In use, the first explosion-proof layer 101, the base film layer 102, the second explosion-proof layer 103, and the waterproof layer 104 are bonded together with OCA optical adhesive to ensure overall strength and light transmittance. An anti-fingerprint coating 105 is applied above the waterproof layer 104. This coating contains nanomaterials 106 and a wear-resistant layer 107, which can effectively reduce fingerprint adhesion. The release paper 2 and the peel-off sheet 3 facilitate quick installation by the user. The protective strip 4 provides edge protection for the main body 1 of the screen protector. The special surface treatment technology of the nanomaterials 106 makes it difficult for oil stains to adhere. Combined with the wear-resistant layer 107, it extends the service life. By optimizing the material combination and surface treatment process, the main body 1 of the screen protector achieves multiple functions such as anti-fingerprint, explosion-proof, waterproof and wear-resistant, significantly improving the user experience.
