Embodiment 1

[0042] Embodiment 1 (embodiment 1-6 is chemical method)

[0043] The present embodiment provides a kind of preparation method of antibacterial glass, concrete steps are:

[0044] Cut the original glass sheet with a thickness of 4mm, put it into the mixed molten salt of potassium nitrate, silver nitrate and ferrous sulfate, in which the mass fraction of silver ions is 0.1%, and the mass concentration of ferrous ions is 0.2%. Conditions, ion exchange for 2 minutes, then the glass is taken out, cooled and cleaned to obtain the antibacterial glass.

Embodiment 2

[0046] The present embodiment provides a kind of preparation method of antibacterial glass, concrete steps are:

[0047] Cut the original glass sheet with a thickness of 4mm and put it into the mixed molten salt of potassium nitrate, silver nitrate and ferrous sulfate, in which the mass fraction of silver ions is 3%, and the mass concentration of ferrous ions is 1.5%. Under the condition of ℃, ion exchange for 1 minute, then the glass is taken out, cooled and washed to obtain the antibacterial glass.

Embodiment 3

[0049] The present embodiment provides a kind of preparation method of antibacterial glass, concrete steps are:

Abstract

The invention belongs to the technical field of glass preparation, and in particular relates to a preparation method of antibacterial glass and antibacterial vacuum glass. The preparation method of the antibacterial glass comprises the following steps of performing one-step ion exchange on the glass with a salt solution or melt containing silver and ferrous ions, and introducing antibacterial ions into the glass body to obtain the antibacterial glass. The invention realizes the exchange of antibacterial ions and sodium and potassium ions inside the glass through a one-step ion exchange method, and introduces antibacterial ions into the glass body, the method is simple and effective, and the cost is saved. By introducing ferrous ions in the ion exchange process, the oxidation of antibacterial ions can be effectively inhibited, the concentration of antibacterial ions can be effectively increased, and the decrease of light transmittance of glass can be avoided, which is beneficial to the improvement of antibacterial glass performance and light transmission performance.

Description

technical field [0001] The invention belongs to the technical field of glass preparation, and in particular relates to a preparation method of antibacterial glass and antibacterial vacuum glass. Background technique [0002] With the advancement of science and technology and the improvement of people's living standards, people pay more and more attention to environmental sanitation. Refrigerators and freezers are becoming more and more popular as heat preservation and refrigeration equipment in people's daily life. Now the glass used for ordinary freezer doors is hollow glass. Compared with vacuum glass, its thickness is large and its heat insulation performance is poor. There is a small amount of application in luxury goods such as wine cabinets; as for antibacterial vacuum glass, there is little research, and there are no related mature products yet. [0003] Antibacterial glass, also known as green glass, is a new type of ecological functional material, which is of great...
