Abstract

The invention discloses colorless transparent antibacterial antiviral glass and a preparation method thereof. The preparation method comprises the steps that preheated glass is immersed in mixed molten salt containing potassium nitrate and a silver-loaded antibacterial agent, silver ions are introduced into the glass through ion exchange effect, and cooling is conducted so as to obtain the colorless transparent antibacterial antiviral glass. The silver-loaded antibacterial agent is adopted to replace a silver nitrate component in a previous high-temperature molten salt ion exchange method, andin the process of preparing the colorless transparent antibacterial antiviral glass by using the molten salt ion exchange method, the silver-loaded antibacterial agent can slowly release silver ionsand undergo ion exchange with sodium ions and the like in the glass, so the defect that the antibacterial component, namely silver ions are easily oxidized in a traditional method is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of glass preparation, and relates to a colorless transparent antibacterial and antiviral glass and a preparation method thereof. Background technique [0002] With the rapid development of domestic science and technology and the continuous improvement of people's living standards, people are paying more and more attention to environmental sanitation conditions. In people's daily life, glass is one of the most widely used materials, such as glass shower rooms, various touch screens in public places, private mobile phones, tablets, etc. all use glass products. However, during the long-term use of glass, the sweat stains, scratches and warm and humid environment left on the glass surface provide favorable conditions for the growth of bacteria and viruses, which have a serious impact on human health and quality of life. Therefore, processing ordinary glass into antibacterial glass can inhibit the growth of bact...
