Problems solved by technology

[0002] With the development of science and technology, the functions of mobile phones are becoming more and more powerful. From the initial simple SMS and call functions to the current functions of taking pictures, surfing the Internet, shopping, and payment, mobile phones have gradually become an indispensable necessity in people's lives. With the widespread use of mobile phones in people's lives, consumers' requirements for mobile phones are also constantly improving. In addition to requiring mobile phones to meet consumers' daily work and life, they also hope that they will not affect their own health. The existing mobile phone glass After the cover is used for a long time, the white surface of the glass will breed mold, E. coli and other bacteria, which will affect the health of the body

Embodiment 1

[0049] A method for preparing an antibacterial glass cover plate includes the following steps:

[0050] Step 1: Plasma cleaning the substrate;

[0051] Step 2: Plating the first layer of silicon film on the surface of the substrate;

[0052] Step 3: plating a silver-titanium composite antibacterial film on the surface of the first silicon film of the substrate;

[0053] Step 4: Plating a second layer of silicon film on the surface of the silver-titanium composite antibacterial film of the substrate.

[0054] Wherein, the specific operation of the first step is: evacuating the vacuum chamber of the vacuum coating machine in which the substrate to be coated is placed, and then turning on the high-voltage intermediate frequency power supply electrically connected to the two electrodes of the ion source cleaning mechanism of the vacuum coating machine, At the same time, the gas delivery device of the vacuum coating machine transports a mixed gas of argon and oxygen into the cleaning chambe...

Abstract

The invention relates to the technical field of glass cover plates, in particular to an antibacterial glass cover plate and a preparation method thereof. The preparation method comprises: 1, subjecting a substrate to plasma cleaning; 2, plating a first layer of silicon film on the surface of the substrate; 3, plating a silver-titanium composite antibacterial film on the surface of the first layerof silicon film of the substrate; and 4, plating a second layer of silicon film on the surface of the silver-titanium composite antibacterial film of the substrate. The antibacterial glass cover platecomprises the glass substrate, the first layer of silicon film plated on the surface of the glass substrate, the silver-titanium composite antibacterial film plated on the surface of the first layerof silicon film, the second layer of silicon film plated on the surface of the silver-titanium composite antibacterial film, and an AF anti-fingerprint film plated on the surface of the second layer of silicon film, wherein the thickness of the first silicon film layer and the thickness of the second silicon film layer are both 8-10 nm, and the thickness of the silver-titanium composite antibacterial film is 30-60 nm. The glass cover plate provided by the invention has good bacteriostatic and bactericidal effects.
