specific Embodiment approach 1

[0024] Embodiment 1: The preparation method of the anti-reflection anti-scratch anti-fingerprint mobile phone glass window protective screen of this embodiment is carried out according to the following steps:

[0025] 1. Use CNC processing technology to cut, punch and chamfer the ultra-thin glass with a thickness of 0.5-1.0mm according to the design size and shape of the product, and obtain the ultra-thin glass products that have been preliminarily processed;

[0026] 2. Immerse the ultra-thin glass product preliminarily treated in step 1 into hydrofluoric acid solution for a predetermined period of corrosion. The corrosion depth is 3 μm to 0.2 mm. Clean the corroded ultra-thin glass product with a detergent and dry it to obtain a frosted appearance. Ultra-thin glass products with silky touch;

[0027] 3. Chemically toughening the ultra-thin glass product with frosted appearance and silky touch obtained in step 2 to obtain a toughened ultra-thin glass product;

[0028] 4. Att...

specific Embodiment approach 2

[0033] Embodiment 2: This embodiment differs from Embodiment 1 in that the thickness of the ultra-thin glass described in Step 1 is 0.8 mm. Other steps and parameters are the same as those in the first embodiment.

specific Embodiment approach 3

[0034] Embodiment 3: This embodiment is different from Embodiment 1 in that the weight ratio of hydrofluoric acid in the hydrofluoric acid solution in step 2 is 10% to 20%. Other steps and parameters are the same as those in the first embodiment.

Abstract

The invention relates to a preparation method of an anti-reflection, anti-scratching and fingerprint-proof mobile phone glass view-window protective screen, and belongs to the technical field of preparation methods of mobile phone glass view-window protective screens. The aim of the invention is to solve the problems that the existing mobile phone glass view-window protective screen is poor in anti-reflection effect, easy to scratch and blurry due to fingerprints. The anti-reflection, anti-scratching and fingerprint-proof mobile phone glass view-window protective screen is prepared by the following steps: (1) carrying out preliminary treatment on ultra-thin glass by adopting a Computer Numerical Control (CNC) processing technology; (2) immersing the preliminarily treated ultra-thin glass into a hydrofluoric acid solution for erosion; (3) tempering the ultra-thin glass; (4) laminating a SiO2 anti-reflection film on the surface of the tempered ultra-thin glass product; (5) laminating a hydrophobic protective film on the SiO2 anti-reflection film; (6) plating a superhard film on the upper surface of the hydrophobic protective film, and then plating a fingerprint-proof layer on the surface of the superhard film; (7) plating a non-conductive film layer on the lower surface of the tempered ultra-thin glass product; and (8) gluing an anti-cracking film on the lower surface of the non-conductive film layer in a bubble-free manner.

Description

technical field [0001] The invention belongs to the technical field of a method for preparing a mobile phone glass window protective screen. Background technique [0002] The liquid crystal display (LCD) on a mobile phone is usually composed of two pieces of ultra-thin ITO (indium tin oxide) glass with a thickness of 0.4-0.55mm. If the LCD is directly exposed, it will be easily damaged during use. Therefore, the LCD on the existing mobile phone All are equipped with window protection screens that not only protect the LCD, but also play the role of beautiful decoration. There are two ways to make the existing window protection screen: 1. The way of mold opening and injection molding, also known as IMD technology (in-mold inlay technology), the advantage of this method is that it is easy to realize the curved surface shape, and the disadvantage is that the cost is high and the surface is scratch-resistant Poor ability; 2. Flat CNC (computer numerical control machine tool) cut...
