Description

Technical Field

[0001] The utility model belongs to the technical field of electronic product accessories, and in particular relates to a protective film with excellent anti-ultraviolet performance. 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 users use electronic products, they need to stick a transparent protective film on the screen of the electronic products. The existing transparent protective films have relatively simple functions and do not have the function of ultraviolet protection. When users use electronic products for a long time, ultraviolet rays will be reflected through the screen and cause damage to the user's eyes, reducing the practicality of the transparent protective film. Utility Model Content

[0004] The utility model provides a protective film with excellent anti-ultraviolet performance, aiming to solve the problem that the existing transparent protective film has a relatively single function and has no anti-ultraviolet function. When the user uses electronic products for a long time, the ultraviolet rays will be reflected through the screen, causing damage to the user's eyes, thus reducing the practicality of the transparent protective film.

[0005] The utility model is realized in this way, a protective film with excellent anti-ultraviolet performance comprises a base layer, and an anti-ultraviolet layer is fixedly connected to the upper surface of the base layer, a tempered glass layer is bonded to the upper surface of the anti-ultraviolet layer, and an insulation layer is fixedly connected to the upper surface of the tempered glass layer.

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

[0007] Preferably, an anti-delamination protective film is bonded to the lower surface of the base layer, and a side film is fixedly connected to the outer wall of the anti-delamination protective film, and the side film is coated on the outer wall around the film body.

[0008] Preferably, a glass fiber toughened woven mesh is provided in the anti-delamination protective film.

[0009] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0010] The heat-insulating layer is a transparent silicone coating, which can be directly sprayed on the tempered glass layer to form a film layer with a thickness of about microns. This film layer can reflect the infrared part of the sunlight to achieve the heat-insulating effect, making the protective film heat-insulating. The scratch resistance of the protective film is improved through the tempered glass layer. The material of the UV protection layer can be formed by drying a mixture of fluorescent powder and adhesive. The UV protection layer can be used to make the protective film have UV protection function, thereby increasing the functionality of the protective film and improving the practicality of the protective film.

[0014] 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.

[0015] 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.

[0016] The utility model embodiment provides a protective film with excellent UV protection performance, such as Figure 1-2 As shown, it includes a base layer 2, and an anti-ultraviolet layer 3 is fixedly connected to the upper surface of the base layer 2, a tempered glass layer 4 is bonded to the upper surface of the anti-ultraviolet layer 3, and a heat insulation layer 5 is fixedly connected to the upper surface of the tempered glass layer 4.

[0017] It should be noted that, since the existing transparent protective film has a relatively simple function and does not have an ultraviolet protection function, when the user uses electronic products for a long time, the ultraviolet rays will be reflected through the screen, causing damage to the user's eyes, reducing the practicality of the protective film. Therefore, in order to solve the problem that the existing transparent protective film has a relatively simple function, the heat-insulating layer 5 of this scheme is a transparent silicone coating, which can be directly sprayed on the tempered glass layer 4 to form a film layer with a thickness of about 20 microns. This film layer can reflect the infrared part of the sun's rays to achieve a heat-insulating effect, so that the protective film has heat-insulating properties. The tempered glass layer 4 improves the scratch resistance of the protective film. The material of the ultraviolet protection layer 3 can be formed by drying a mixture of fluorescent powder and adhesive. The ultraviolet protection layer 3 makes the protective film have an ultraviolet protection function, which increases the functionality of the protective film and improves the practicality of the protective film.

[0018] In a further preferred embodiment of the present invention, Figure 1 As shown, the upper surface of the heat insulation layer 5 is coated with a self-cleaning layer 6.

[0019] In this embodiment, the main component of the self-cleaning layer 6 is titanium dioxide. Titanium dioxide has super hydrophilicity because it can produce good photocatalytic properties under the action of light energy. By utilizing this super hydrophilic property (the opposite of the hydrophobic property), very small water droplets can be gathered into large water droplets, which fall off under the action of gravity, so that the stains on it can be easily washed away by water, making the protective film easy to clean.

[0020] In a further preferred embodiment of the present invention, Figure 1-2 As shown, the lower surface of the base layer 2 is bonded with an anti-delamination protective film 1, and the outer wall of the anti-delamination protective film 1 is fixedly connected with a side film 101, and the side film 101 is wrapped around the outer wall of the film body.

[0021] In this embodiment, the protective film is composed of multiple layers, resulting in stratification around the edges of the protective film when it is in use. The side film 101 is used to cover the outer walls around the film body, thereby improving the integrity of the surface around the protective film and preventing stratification around the protective film.

[0022] In a further preferred embodiment of the present invention, a glass fiber toughening woven mesh is arranged inside the anti-delamination protective film 1 .

[0023] In this embodiment, the toughness of the anti-delamination protective film 1 is improved by toughening the woven mesh with glass fibers.
