Problems solved by technology

[0005] In order to improve the light transmittance and wear resistance of mobile phone glass, the surface of mobile phone glass will be coated, and the most common coating method currently used is vacuum coating SiO 2 and TiO 2 , the current mobile phone glass film has insufficient light transmittance, and the wear resistance cannot meet high requirements, and at present, for the mobile phone glass screen with a large area of ​​the mobile phone panel, it is very easy to be accidentally pinched or crushed.
In addition, the anti-fingerprint effect of the existing mobile phone glass is poor, and the fingerprints left during use are difficult to wipe

Abstract

The invention relates to the technical field of film plating for glass panels of mobile phones, in particular to a preparation method of a superhard anti-fingerprint film for a glass panel of a mobile phone. The method includes the steps of carrying out pretreatment, specifically, the glass printed surface of the mobile phone is subjected to ultrasonic cleaning through cleaning fluid and then is dried; carrying out coating of a bottom film layer, specifically, the cleaned glass printing layer surface of the mobile phone is coated with the gold bottom film layer; plating a SiO2 film, specifically, the surface of the solidified bottom film layer of the glass of the mobile phone is plated with the SiO2 film in a vacuum mode; plating a TiO2 film, specifically, the SiO2 film is plated with the TiO2 film; and spraying UV finish paint, specifically, the UV finish paint is sprayed to the surface of the TiO2 film. The obtained gold transparent film layer can show a shiny gold color at different visions, the transmittance of light is high, and abrasion resistance is good; moreover, the method has the characteristics that the process is simple and the film layer has good compactness.

Description

technical field [0001] The invention relates to the technical field of film coating on mobile phone glass panels, in particular to a method for preparing a superhard anti-fingerprint film on the glass panel of mobile phones. Background technique [0002] The glass panel of mobile phone is a key component of mobile phone communication equipment, and it is the part that occupies the largest area of ​​the whole mobile phone. Therefore, the printing and coating technology of mobile phone glass panel is getting more and more attention. [0003] As a mobile phone glass panel, it is not an ordinary piece of glass. Considering the requirements of volume, weight, touch and light transmission, etc., the thickness of mobile phone glass should generally be controlled between 0.5mm and 2.0mm, and the surface must be very flat Smooth and clean, good light transmission performance, overall toughness, no cracks under pressure, and Mohs hardness must be at least 6 or above, so as to ensure t...
