Problems solved by technology

On the one hand, the transmittance of the glass shows a rapid decline with the thickness of the metal layer; on the other hand, metals such as Ag exposed to the air are easily oxidized, which affects its aesthetics and antibacterial effect.
Therefore, various antibacterial substances will have limitations due to their shortcomings

preparation example Construction

[0039] Another aspect of the embodiments of the present invention also provides a method for preparing highly transparent antibacterial glass, which includes:

[0040] Provides a transparent base,

[0041] The antibacterial compound material is deposited on the transparent substrate by physical vapor deposition method or chemical coating method to form an antibacterial coating and obtain highly transparent antibacterial glass.

[0042] In some embodiments, the physical vapor deposition method includes at least any one of magnetron sputtering, electron beam evaporation and the like, but is not limited thereto.

[0043] In some embodiments, the preparation method of the highly transparent antibacterial glass specifically includes:

[0044] Using magnetron sputtering technology, the M x Zn 1-x ON y A ternary compound is used as a target material, or a mono- or binary compound in M ​​and Zn is used as a target material, and the antibacterial coating is deposited on the transpare...

Embodiment 1

[0054] The present embodiment is a kind of preferred antibacterial glass of the present invention, and the material of transparent substrate is glass, and the area is Sn 0.48 Zn 0.52 The 2.5% copper sheet of the O target is attached to it. Vacuum the magnetron sputtering apparatus to an air pressure of 9.0×10 -4 Pa, the cathode is connected to a 100W RF power supply, and the argon gas with a flow rate of 40sccm is introduced to make its working pressure 1.1×10 -1 Pa, the sputtering time is controlled so that the thickness of the deposited antibacterial coating is 10nm, and highly transparent antibacterial glass is obtained. The antibacterial glass has no change in appearance after 1000 hours of high-temperature and high-humidity accelerated aging test (85°C, 85%RH), and does not affect the transmittance and antibacterial efficiency at the same time. The average transmittance of the high-transmittance antibacterial glass in the range of 400-800nm ​​is 89.6%. The inhibition ...

Embodiment 2

[0056] This embodiment is a preferred antibacterial glass of the present invention, and the material of the transparent substrate is glass. Sputtering target composition is Al 0.05 Zn 0.95 ow 0.02 . Vacuum the magnetron sputtering apparatus to a pressure of 7.0×10 -4 Pa, the cathode is connected to a 100W RF power supply, and the argon gas with a flow rate of 40sccm is introduced to make its working pressure 2×10 -1 Pa, the sputtering time is controlled so that the thickness of the deposited antibacterial coating is 100nm, and a highly transparent antibacterial glass is obtained. Its average transmittance in the range of 400-800nm ​​is 88%. The inhibition rate of the high-transparency antibacterial glass to Escherichia coli was measured by the elution method, and it reached 99%. The results of the transmittance and antibacterial rate can be seen in Table 1.

Abstract

The invention discloses an antibacterial compound material, antibacterial glass, a preparation method and an application thereof. The molecular formula of the antibacterial compound material is MxZn1-xO or MxZn1-xONy, M comprises Sn, Mg, Al, Ga, In, Si and the like, and N comprises Cu, Ag, Ti, W and the like. The antibacterial glass comprises a transparent substrate and an antibacterial coating, and the antibacterial coating is formed by the antibacterial compound material. The preparation method comprises the following steps: selecting substances of the antibacterial coating, determining the proportion of each substance and the thickness of the coating, and depositing the antibacterial coating on the surface of a transparent substrate through a physical vapor deposition method to obtain the transparent and colorless antibacterial glass with a good antibacterial effect. The compound antibacterial material has excellent weather resistance (oxidation resistance, high temperature resistance and high humidity resistance), good antibacterial efficiency and excellent light transmission performance, and the average transmittance in the visible light range is 80% or above, preferably 90% or above.

Description

technical field [0001] The invention belongs to the technical field of antibacterial glass, and in particular relates to an antibacterial compound material and a synthesis method thereof, and a highly transparent coated antibacterial glass as well as a preparation method and application thereof. Background technique [0002] As a new type of ecological functional material, antibacterial glass plays an important role in the daily life and medical treatment of modern human beings. In some aspects, it can prevent objects from being infringed by bacteria and also protect human life and health. In kitchens, toilets, bathrooms, hospital wards and other places where bacteria are prone to breed, using antibacterial glass instead of ordinary glass will not only reduce the aesthetics of the device, but also inhibit the growth and spread of bacteria, bringing protection to people's health. [0003] The current antibacterial glass can be roughly divided into two categories. One is to co...
