Description

Technical Field

[0001] The utility model belongs to the technical field of electronic product accessories, and in particular relates to an antistatic protective film. Background Art

[0002] Protective films can be divided into digital product protective films, car protective films, household protective films, food preservative protective films, etc. according to their uses. With the popularity of digital products such as mobile phones in China, protective films have gradually become a general term for screen protective films, and their functions in the field of screen protective films are also varied. The materials have evolved from the earliest PP materials to the popular AR materials today, and have gradually been accepted by the majority of mobile phone users. Functionally, the protective film is to put a layer of film on the physical objects we want to protect. Now there are functional protective films on the market, such as AR anti-reflective film, AG matte anti-reflective film, mobile phone mirror film, anti-peep film, high-definition anti-scratch film, etc.

[0003] When using electronic products, users need to stick a transparent protective film on the screen of the electronic products. Currently, the existing transparent protective films have relatively simple functions and poor anti-static effects. When used, impurities will be electrostatically adsorbed on the surface of the protective film, making it difficult to keep the surface of the protective film clean. Utility Model Content

[0004] The utility model provides an antistatic protective film, aiming to solve the problem that the existing transparent protective film has a single function and a poor antistatic effect, and impurities are electrostatically adsorbed on the surface of the protective film during use, making it difficult to keep the surface of the protective film clean.

[0005] The utility model is implemented as follows: an antistatic protective film comprises a base layer, and an anti-ultraviolet layer is bonded to the upper surface of the base layer, a heat insulation layer is fixedly connected to the upper surface of the anti-ultraviolet layer, and a first antistatic layer is fixedly connected to the upper surface of the heat insulation layer, and a tempered glass layer is bonded to the upper surface of the first antistatic layer.

[0006] Preferably, the upper surface of the tempered glass layer is coated with a self-cleaning layer.

[0007] Preferably, antistatic chemical nanomaterials are added inside the self-cleaning layer.

[0008] Preferably, a second antistatic layer is bonded to the lower surface of the base layer.

[0009] Preferably, the outer wall of the base layer is provided with an anti-delamination wall.

[0010] Preferably, a protrusion is fixedly connected to the inner wall of the anti-delamination wall.

[0011] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0012] The scratch resistance of the protective film is improved by the tempered glass layer. The heat insulation layer is made of transparent silicone material, which can reflect the infrared part of the sunlight to achieve the heat insulation effect, so that the protective film has heat insulation properties. The material of the UV protection layer can be formed by drying a mixture of fluorescent powder and adhesive. The UV protection layer is used to give the protective film an anti-UV function. The first antistatic layer is an antistatic polycarbonate layer. The first antistatic layer provides the protective film with antistatic ability, thereby increasing the functionality of the protective film and improving the practicability of the protective film.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0017] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0018] The utility model embodiment provides an antistatic protective film, such as Figure 1-2 As shown, it includes a base layer 1, and an anti-ultraviolet layer 2 is bonded to the upper surface of the base layer 1, a heat insulation layer 3 is fixedly connected to the upper surface of the anti-ultraviolet layer 2, and a first antistatic layer 4 is fixedly connected to the upper surface of the heat insulation layer 3, and a tempered glass layer 5 is bonded to the upper surface of the first antistatic layer 4.

[0019] It should be noted that, since the existing transparent protective film has a relatively single function and a poor anti-static effect, impurities will be electrostatically adsorbed on the surface of the protective film during use, making it difficult to keep the surface of the protective film clean. Therefore, in order to solve the problem of the existing transparent protective film having a relatively single function, this solution improves the scratch resistance of the protective film through the tempered glass layer 5. The heat insulation layer 3 is a transparent silicone material, which can reflect the infrared part of the sun's rays to achieve a heat insulation effect, so that the protective film has heat insulation properties. The material of the ultraviolet protection layer 2 can be formed by drying a mixture of fluorescent powder and an adhesive. The ultraviolet protection layer 2 is used to give the protective film an anti-ultraviolet function. The first antistatic layer 4 is an antistatic polycarbonate layer. The first antistatic layer 4 provides the protective film with antistatic ability, thereby increasing the functionality of the protective film and improving the practicality of the protective film.

[0020] In a further preferred embodiment of the present invention, Figure 1 As shown, the upper surface of the tempered glass layer 5 is coated with a self-cleaning layer 6 .

[0021] In this embodiment, the main component of the self-cleaning layer 6 is a super hydrophilic silicon oxide film, which quickly forms a super hydrophilic film. By utilizing this super hydrophilic property (the opposite of the hydrophobic property), very small water droplets are gathered into large water droplets, and pollutants are washed away under the scouring effect of natural rainwater and gravity, thereby achieving the purpose of self-cleaning.

[0022] In a further preferred embodiment of the present invention, Figure 1 As shown, antistatic chemical nanomaterials are added inside the self-cleaning layer 6 .

[0023] In this embodiment, in view of the poor domestic air quality and serious pollution, anti-static chemical nanomaterials are added to prevent static electricity and do not absorb floating dust and particles in the air, making it difficult for dust to adhere to the surface of the protective film.

[0024] In a further preferred embodiment of the present invention, a second antistatic layer 7 is bonded to the lower surface of the base layer 1 .

[0025] In this embodiment, the second antistatic layer 7 is an antistatic polyvinyl chloride layer. The second antistatic layer 7 improves the antistatic ability of the lower surface of the protective film, reduces dust adsorbed on the lower surface of the protective film, and facilitates the laying of the protective film.

[0026] In a further preferred embodiment of the present invention, an anti-delamination wall 101 is provided on the outer wall of the base layer 1 .

[0027] In this embodiment, the protective film is composed of multiple layers. When in use, stratification is likely to occur between the layers. The anti-stratification wall 101 shields the periphery of the film body, thereby reducing the stratification phenomenon of the protective film.

[0028] In a further preferred embodiment of the present invention, a protrusion 102 is fixedly connected to the inner wall of the anti-delamination wall 101 .

[0029] In this embodiment, the contact area and friction force between the anti-delamination wall 101 and each level are increased by the protrusions 102 , thereby preventing each level from being separated from the anti-delamination wall 101 .
