Description
Technical Field
The invention relates to the field of antiviral materials, in particular to an antiviral glass material and a preparation method thereof.
Background
The anti-bacteria material is a material capable of killing virus and bacteria or inhibiting the growth and reproduction of virus and bacteria. The anti-bacterial agent is added to the carrier material, so that the anti-bacterial agent can exert an anti-bacterial effect on the basis of not interfering with the original function of the carrier material, and the carrier material can play a role in storing or protecting the anti-bacterial agent.
Antibacterial glass has been developed for many years, and mainly uses ion exchange method, magnetron sputtering method and the like to modify some antibacterial ions on the surface of the glass. Such as: patent publication No. CN 110357455A discloses that one-step ion exchange is performed on glass and a solution or a melt containing silver and ferrous ions to realize the exchange between antibacterial ions and sodium and potassium ions in the glass, the antibacterial ions are introduced into a glass body, and the antibacterial ions are modified on the surface of the glass to obtain the antibacterial glass; however, the ion exchange method has low preparation efficiency, the content of introduced antibacterial ions is limited, the antibacterial performance of the glass is greatly limited, and bacteria are difficult to intercept and inactivate due to the smooth surface of the glass.
Patent publication No. CN 109942208A discloses a preparation method of antibacterial glass, which comprises the following steps: cutting a glass raw material, then carrying out fine carving processing, cleaning, and carrying out preheating treatment to obtain pretreated glass; mixing potassium nitrate and silver nitrate, heating and melting to obtain antibacterial tempering furnace water, and adding the pretreated glass into the antibacterial tempering furnace water for antibacterial tempering treatment to obtain the antibacterial glass. The preparation process is complex, the requirement on the preparation process is high, the antibacterial ion content of the prepared glass surface is low, and the antibacterial performance is insufficient.
At present, antiviral glass is rarely and rarely researched, and the main reason is that the preparation requirement of the antiviral glass is higher than that of the antibacterial glass; and the antiviral material can not be directly modified on the glass surface by an ion exchange or sputtering method like the antibacterial material (the antibacterial glass surface has a small specific surface area and a non-porous structure, and the antiviral material can not be loaded on the glass surface), so that the preparation method of the antibacterial glass can not be applied to the preparation of the antiviral glass. Under the environment of the current global virus epidemic situation, if an antiviral glass which can be highly efficient and durable can be researched, the antiviral glass has great significance for future epidemic prevention work all over the world and is an important technical problem which needs to be solved urgently under the current epidemic situation.
