Problems solved by technology

AF coated glass is coated with a layer of chemical materials on the outer surface of the glass to reduce the surface tension of the glass, so that the glass has strong hydrophobicity, oil resistance and fingerprint resistance. Bacteria will grow on the surface, which will affect people's health. At present, the demand for AF coated glass with antibacterial effect is gradually increasing in all walks of life.
For bacteria problems such as touch screens, the common method is to use alcohol and ultraviolet light for disinfection and sterilization, but both alcohol and ultraviolet disinfection have certain limitations, and corresponding alcohol materials or ultraviolet equipment are required

Abstract

The invention provides a preparation method of AF coated glass with an antibacterial effect. The preparation method comprises the following steps: S1, carrying out ultrasonic cleaning on a glass substrate by using a solvent or a cleaning agent, washing with deionized water, and blow-drying with nitrogen; S2, coating a SiO2 film base layer on the glass substrate in a vacuum coating manner; S3, adding nano-silver into an anti-fingerprint agent, uniformly spraying the treated anti-fingerprint agent onto the SiO2 film base layer on the surface of the glass substrate through a spraying machine, then drying the glass substrate, taking out the glass substrate, and cooling so as to form an antibacterial anti-fingerprint layer; and S4, dispersing SiO2 particles and nano-silver in a solvent to prepare an antibacterial solution, uniformly spraying the antibacterial solution on the antibacterial anti-fingerprint layer of the glass substrate through a spraying machine, drying the glass substrate, taking out the glass substrate, and cooling the glass substrate to form an antibacterial SiO2 film layer. The coated glass provided by the invention has anti-fingerprint and antibacterial effects.

Description

technical field [0001] The invention belongs to the technical field of glass coating, and in particular relates to a preparation method of AF coated glass with antibacterial effect. Background technique [0002] With the continuous development of social economy and the continuous improvement of human living standards, glass has developed from a single lighting, perspective and shelter from wind and rain to multifunctional glass products with various special purposes. AF coated glass is coated with a layer of chemical materials on the outer surface of the glass to reduce the surface tension of the glass, so that the glass has strong hydrophobicity, oil resistance and fingerprint resistance. Bacteria will grow on the surface, which will affect people's health. At present, the demand for AF coated glass with antibacterial effect is gradually increasing in all walks of life. For bacteria problems such as touch screens, the common method is to use alcohol and ultraviolet to disi...
