Abstract

The invention discloses a preparation method of antibacterial glass. The preparation method comprises the following steps: cutting a glass raw material, then carving and processing the glass raw material, and cleaning and pretreating the glass raw material to obtain pre-treated glass; and mixing, heating and melting potassium nitrate and silver nitrate to obtain antibacterial tempering furnace water, and adding the pre-treated glass into the antibacterial tempering furnace water for antibacterial tempering to obtain the antibacterial glass. The preparation method of antibacterial glass is simple in process, and the obtained antibacterial glass has the characteristics of the glass material and is good in antibacterial effect and wide in application.

Description

technical field [0001] The invention relates to the technical field of glass, in particular to a preparation method of antibacterial glass. Background technique [0002] With the development of the country, more and more people frequently touch their mobile phones every day, and many bacteria will be left on the surface of the mobile phone. Some organizations have detected that mobile phones are 10 times dirtier than express parcels. Bacteria that grow in large numbers on the surface of mobile phones will bring certain harm to the human body. Antibacterial glass processed from normal glass can inhibit the growth of various harmful bacteria such as algae, microbes, mildew, and fungi. It has been widely used in medical care, automotive touch screens, and electronic touch screen products for mobile phone covers. However, the antibacterial effect of the existing antibacterial glass is still not very satisfactory, which limits its application. Contents of the invention [000...
