Background

In the actual use process of electronic products, glass panels are required to be used as screen display panels. With the quality of life of consumers, the demand for electronic products is higher and higher. Meanwhile, electronic products, as common articles in general daily life, have a long service life, and consumers can cause the display panel to be stained with certain dirt (especially fingerprint pollution and the like) and bacteria and the like in the using process, thereby affecting the health of people. This requires improvement of the surface properties of the glass panel, for example, in order to improve the antifouling ability of the glass panel, the surface is usually plated with an AF film to improve the antifouling ability against fingerprints and the like; the antibacterial function is achieved by directly coating the antibacterial layer on the surface of the glass panel. As disclosed in the related art (CN106673456A), an antibacterial layer is directly formed on the surface of a glass substrate, and the antibacterial layer is composed of butyl acrylate, hydroxy silicone, propylene glycol, aluminum phosphate, sodium oxide, potassium oxide, silica, dodecyl glucoside, and apatite. The method is mainly characterized in that the AF film is used for realizing the fingerprint prevention function, generally, the AF film is in an outermost structural mode, when the fingerprint prevention AF film function is considered, other fingerprint prevention film layers are not plated on the outer surface of the AF film, the antibacterial layer is singly plated on one layer of structure between the glass substrate and the AF film on the inner side to achieve the antibacterial effect, therefore, the functional film layers are plated on the surface of the glass panel, the functional film layers are positioned on the outer side of the antibacterial layer, the isolation of the functional film layers enables the outer antibacterial function to be poor, and particularly, bacteria and the like are grown on the outer side such as the AF film to cause the overall antibacterial effect to be weakened.

Disclosure of Invention

The invention provides an antibacterial glass panel aiming at the problems in the prior art, and solves the problem of how to realize the combination of fingerprint prevention and high antibacterial performance.

The invention aims to realize the technical scheme that the antibacterial glass panel comprises a glass substrate, wherein a silicon dioxide coating is plated on one side surface of the glass substrate, and the antibacterial glass panel is characterized in that a nanoscale zinc oxide coating I is also plated between the glass substrate and the silicon dioxide coating, an AF film layer is plated on the surface of the silicon dioxide coating, a nanoscale zinc oxide coating II is plated on the surface of the AF film layer, and the thickness of the nanoscale zinc oxide coating II is less than or equal to 5 nm.

The surface of the glass substrate is plated with the first nanoscale zinc oxide coating, so that bacterial pollution between the inner layer and the outer layer can be effectively isolated, and an effective antibacterial function is achieved; meanwhile, since the AF film layer is plated on the outer side, an effective antibacterial function is not formed, bacteria can be attached to the surface in the using process, and the health of a user is affected; meanwhile, the AF film layer is used for improving the fingerprint prevention function, and if the film layer is arranged on the outer side of the AF film layer at will, the function of the AF film layer can be influenced, the invention adopts the nano-scale zinc oxide coating layer II as an antibacterial material on the outer side, and particularly controls the thickness of the nano-scale zinc oxide coating layer II within 5nm, so that the influence of the nano-scale zinc oxide coating layer on the fingerprint prevention function of the AF film layer can be avoided, the antibacterial capability of the functional film layer on the outer side of the nano-scale zinc oxide coating layer I is realized, the integral antibacterial effect of the glass panel is realized, and the defect of poor antibacterial function caused by bacterial adsorption on the AF film layer on the outer side is avoided; meanwhile, the second nanoscale zinc oxide coating is used as the antibacterial film layer, so that the wear resistance of the surface can be improved. Preferably, the thickness of the second nano-scale zinc oxide coating is 1 nm-2 nm. The second thinner nano-zinc oxide coating is adopted, so that the antibacterial function can be effectively realized; and due to the adoption of the nanoscale thin coating, the fingerprint prevention function and the stain resistance of the AF film layer can be still ensured, and the initial water contact angle is more than or equal to 110 degrees.

In the above antibacterial glass panel, the thickness of the AF film layer is preferably 45nm to 60 nm. The AF film layer has more obvious thickness difference relative to the second nanoscale zinc oxide coating on the outer side, and the fingerprint prevention function is more effectively ensured. The AF film layer can be realized by adopting an evaporation mode.

In the above antibacterial glass panel, preferably, the first nanoscale zinc oxide coating layer has a thickness of 8nm to 15 nm. The nano-scale zinc oxide coating layer relatively positioned on the inner side has a certain thickness, so that a better antibacterial function can be ensured.

In the above-described antibacterial glass panel, preferably, the first nanoscale zinc oxide coating layer is doped with nanoscale silica. The nanoscale silicon dioxide is doped in the nanoscale zinc oxide coating layer I, so that the adhesive force between the coating layer and the surface of the glass panel and between the coating layer and the outer silicon dioxide film layer can be better improved, the overall binding force is improved, and the use falling effect is avoided. Preferably, the mass ratio of the nanoscale zinc oxide to the nanoscale silicon dioxide in the nanoscale zinc oxide coating layer I is 1: 0.2 to 0.4. And a small amount of nano-scale silicon dioxide is doped, so that the adhesive force can be improved, and the antibacterial performance of the layer can not be excessively reduced. For the doped coating layer, the nano-scale zinc oxide and the nano-scale silicon dioxide can be synchronously coated during vacuum evaporation, and the evaporation rate and the content between the nano-scale zinc oxide and the nano-scale silicon dioxide are controlled.

In the above antibacterial glass panel, the thickness of the silica plating layer is preferably 10nm to 15 nm.

In the above antibacterial glass panel, preferably, the second nano-zinc oxide coating is doped with 0.3 to 0.5 mass percent of nano tin antimony oxide. In the research process, the invention discovers that a small amount of nano tin antimony oxide is doped in the nano zinc oxide coating II, so that the wear resistance of the surface can be improved to a great extent, and the antibacterial property and the durability of the surface can be better ensured. Here, the doping effect can be achieved by performing simultaneous vacuum plating with the amount controlled during plating.

In summary, compared with the prior art, the invention has the following advantages:

1. according to the anti-fingerprint and anti-fouling glass panel, the nanoscale zinc oxide coating layers are arranged on the outer side of the AF film and the surface of the glass panel, the thickness of the outer side of the AF film is controlled within 5nm, the overall anti-bacterial performance can be effectively realized, the anti-fingerprint and anti-fouling functions of the AF film can be guaranteed, and the anti-fingerprint and anti-fouling glass panel has a high-wear-resistance effect.

2. The nanoscale silicon dioxide is doped in the nanoscale zinc oxide coating I, so that the overall binding force can be better improved, the shedding effect during use is avoided, and meanwhile, the antibacterial performance of the coating can still be ensured by adding a small amount of silica.
