Description

Technical Field

[0001] This utility model relates to the field of glass cover technology, specifically to an oleophobic and hydrophobic self-cleaning mobile phone glass cover. Background Technology

[0002] The glass cover of a mobile phone is an important component of modern smartphones, mainly used to protect the screen and camera while providing a good touch experience;

[0003] Existing mobile phone glass covers are mostly bare and easily attract fingerprints, oil stains, and water stains. To prevent these stains from adhering, tempered glass screen protectors are needed, increasing the cost of using the phone. Furthermore, mobile phone glass covers are easily damaged when dropped during daily use, increasing repair costs. Therefore, we propose an oleophobic and hydrophobic self-cleaning mobile phone glass cover. Utility Model Content

[0004] The purpose of this invention is to provide an oleophobic and hydrophobic self-cleaning mobile phone glass cover, which solves the problems mentioned in the background art. The surface of existing mobile phone glass covers is mostly exposed and easily adheres to fingerprints, oil stains and water stains. In order to prevent fingerprints, oil stains or water stains from adhering, it is necessary to use a tempered glass film with anti-fingerprint, oil stain and water stain adhesion, which increases the cost of using the mobile phone. Moreover, the mobile phone glass cover is easily damaged when it is dropped during daily use, which increases the repair cost of the mobile phone.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an oleophobic and hydrophobic self-cleaning mobile phone glass cover, comprising a glass cover body, a substrate, and further comprising a buffer component and a cleaning component. The cleaning component is mounted on the surface of the substrate, and the buffer component is mounted between the substrate and the cleaning component. When water droplets or dirt-laden substances roll on the surface of the cleaning component, they are carried away to achieve a self-cleaning effect.

[0006] Preferably, the cleaning component includes a hydrophobic layer and an oleophobic layer, and the substrate surface is provided with a mixture of the hydrophobic layer and the oleophobic layer. The hydrophobic layer is made of epoxy siloxane material, and the oleophobic layer is made of polytetrafluoroethylene material.

[0007] Preferably, the buffer assembly includes an adhesive layer and a buffer layer. The buffer layer is provided on the surface of the substrate, and adhesive layers are provided on both the upper and lower sides of the buffer layer. The adhesive layer is made of silicone adhesive material, and the buffer layer is made of polyvinyl butyral material.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] 1. This utility model provides a hydrophobic layer made of epoxy siloxane material and an oleophobic layer made of polytetrafluoroethylene material on the surface of the substrate, and the oleophobic and hydrophobic layers are arranged alternately to form an extremely thin coating on the substrate surface, which effectively enhances the hydrophobic and oleophobic properties of the surface. In addition, due to the combination of hydrophobic and oleophobic properties, when water droplets or substances contaminated with dirt roll on its surface, they can be carried away, achieving a self-cleaning effect. Moreover, this effect can significantly reduce the cleaning frequency under normal use of the equipment.

[0010] 2. This utility model provides a buffer layer made of polyvinyl butyral between the substrate and the oleophobic and hydrophobic layers. When the glass cover body is impacted by external force, it provides a buffering effect on the oleophobic and hydrophobic layers, while also protecting the substrate, increasing the strength and service life of the glass cover body. At the same time, the adhesive layer facilitates the assembly of the substrate with the oleophobic and hydrophobic layers. Attached Figure Description

[0016] 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.

[0017] Example

[0018] Please see Figures 1-4 The figure shows an oleophobic and hydrophobic self-cleaning mobile phone glass cover, which includes a glass cover body 1, a substrate 2, a buffer component and a cleaning component. The cleaning component is installed on the surface of the substrate 2, and the buffer component is installed between the substrate 2 and the cleaning component. When water droplets or dirt-stained substances roll on the surface of the cleaning component, they are carried away to achieve a self-cleaning effect.

[0019] Furthermore, the cleaning component includes a hydrophobic layer 3 and an oleophobic layer 4. The surface of the substrate 2 is provided with a mixture of the hydrophobic layer 3 and the oleophobic layer 4. The hydrophobic layer 3 is made of epoxy siloxane material, and the oleophobic layer 4 is made of polytetrafluoroethylene material.

[0020] The substrate 2 is made of tempered glass. A hydrophobic layer 3 made of epoxy siloxane material and an oleophobic layer 4 made of polytetrafluoroethylene material are formed on the surface of the substrate 2. The oleophobic layer 4 and the hydrophobic layer 3 are arranged alternately to form an extremely thin coating on the surface of the substrate 2, which effectively enhances the hydrophobic and oleophobic properties of the surface. In addition, due to the combination of hydrophobicity and oleophobicity, when water droplets or dirt-laden substances roll on its surface, they can be carried away, achieving a self-cleaning effect. Moreover, this effect can significantly reduce the cleaning frequency under normal use of the equipment.

[0021] Based on the aforementioned scheme, the buffer assembly includes an adhesive layer 5 and a buffer layer 6. The surface of the substrate 2 is provided with a buffer layer 6, and the upper and lower sides of the buffer layer 6 are provided with adhesive layers 5. The adhesive layer 5 is made of silicone adhesive material.

[0022] As a further improvement of this invention, the buffer layer 6 is made of planar polyvinyl butyral material;

[0023] A buffer layer 6 made of polyvinyl butyral is provided between the substrate 2 and the oleophobic layer 4 and the hydrophobic layer 3, and an adhesive layer 5 made of silicone adhesive is provided on the upper and lower surfaces of the buffer layer 6. When the glass cover body 1 is impacted by external force, it buffers the oleophobic layer 4 and the hydrophobic layer 3, and protects the substrate 2, increasing the strength and service life of the glass cover body 1. At the same time, the adhesive layer 5 facilitates the assembly of the substrate 2 with the oleophobic layer 4 and the hydrophobic layer 3.

[0024] It should be noted that this utility model is an oleophobic and hydrophobic self-cleaning mobile phone glass cover. When water droplets or dirt-stained substances roll on the surface of the glass cover body 1, the combination of hydrophobicity and oleophobicity can carry them away, achieving a self-cleaning effect. Moreover, this effect can significantly reduce the cleaning frequency under normal device use. In addition, when the glass cover body 1 is impacted by external force, a buffer layer 6 made of polyvinyl butyral material is provided between the substrate 2 and the oleophobic layer 4 and the hydrophobic layer 3, which has a buffering effect on the oleophobic layer 4 and the hydrophobic layer 3, and at the same time protects the substrate 2, increasing the strength and service life of the glass cover body 1. Meanwhile, the adhesive layer 5 facilitates the assembly of the substrate 2 with the oleophobic layer 4 and the hydrophobic layer 3.
