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 , due to the limitation of steamed film raw materials for vacuum coating, the coating can only obtain a layer of transparent film material. If it is coated with ferrous metals, it will reduce the light transmittance and transparency of the mobile phone glass, which obviously cannot meet the needs of mobile phone glass panels.

Abstract

The invention relates to the technical field of coating of a glass panel of a mobile phone, specifically to a golden coating process for the cover glass of a mobile phone. The golden coating process comprises the following steps: pretreatment: ultrasonically cleaning the printing surface of the cover glass of the mobile phone by using a cleaning solution and then drying the printing surface; coating of a golden bottom film layer: coating the cleaned surface of the printing layer of the cover glass with the golden bottom film layer; plating of a SiO2 film: coating the surface of the cured golden bottom film layer of the cover glass with a layer of the SiO2 film through vacuum plating; plating of a TiO2 film: plating the SiO2 film with a layer of the TiO2 film; and spraying of a UV finishing coat: spraying the UV finishing coat onto the surface of the TiO2 film. An obtained golden transparent film presents a flashing golden color from different view points, has high light transmittance and good wear resistance and has the characteristics of simple process and good compactness.

Description

technical field [0001] The invention relates to the technical field of mobile phone glass panel coating, in particular to a gold coating process for mobile phone glass. 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 that the mobile phone glass has sufficient surface streng...
