Problems solved by technology

In the field of touch panels, the anti-fingerprint film applied on the glass substrate (especially the strengthened glass substrate) has low friction resistance, resulting in a short service life, which needs to be improved and improved
The main problem is that the glass substrate, especially the strengthened glass substrate, basically does not have conductivity. In actual use, due to external factors such as film coating / tearing, frequent operation and friction, a large amount of charge accumulates on the surface of the anti-fingerprint film layer. In turn, the bonding strength between the film layer and the glass substrate is weakened, and the film layer is separated from the substrate during frictional use, which accelerates the failure of the film layer

Abstract

The invention provides an anti-fingerprint film, a glass product and a preparation method of the glass product. The anti-fingerprint film comprises a conductive film layer, a transition layer, a silicon dioxide layer and an anti-fingerprint film layer, all of which are sequentially stacked. The conductive film layer comprises one or more kinds of In, oxide of In, Sn and oxide of Sn, and the transition layer comprises Si3N4, SiON and SiO2. The glass product comprises a glass substrate and the anti-fingerprint film. The substrate is adjacent to the conductive film layer. The preparation method of the glass product comprises the step of sequentially preparing the conductive film layer, the transition layer, the silicon dioxide layer and the anti-fingerprint film layer on the glass substrate by using a magnetron sputtering method. The anti-fingerprint film has excellent friction resistance, waterproof performance and anti-fingerprint performance, and is long in service life.

Description

Technical field[0001]The present invention relates to the field of glass articles, and more particularly to anti-fingerprint films, glass articles, and preparation methods thereof.Background technique[0002]In order to improve customer experience, mobile phones, flat panels, etc., will usually apply a layer of anti-fingerprint film, improve the anti-dirt and lubrication characteristics of the glass panel, and this technology is deeply concerned. In the field of touch panels, the anti-finger membrane resistance to the glass substrate (especially the reinforced glass substrate) is not high, resulting in no longer service life, and needs to be improved and improved. The main problem is in that the glass substrate is particularly reinforced glass substrate, which is basically not electrically conductive, and an external factor such as a film / tear film, frequent operation friction is substantially used in reality, and a large amount of charge is concentrated on the surface of the anti-f...
