ANTIBACTERIAL MOLTEN SALT, AND GLASS AND PREPARATION METHOD THEREFOR
The present invention provides an antibacterial molten salt and antibacterial glass obtained by using the antibacterial molten salt to perform antibacterial metal ion exchange. The antibacterial metal ion in the antibacterial molten salt is a copper ion, and the antibacterial molten salt is a multi-component composite sulfate. In the present invention, Cu ions exist stably in the glass after ion exchange, and no black CuO or polluting waste gas is generated. The compositional design of the ternary sulfate molten salt enables the glass to be melted at a temperature of 430-500°C or 440-470°C, facilitating antibacterial ion exchange of mainstream glass in industry. The glass needs to be preheated before ion exchange is performed. The preheating temperature T1 and the ion exchange temperature T2 of the antibacterial molten salt need to be controlled such that T2 − T1 < 50°C, and the ion exchange time is 2-10 min. The copper content of the antibacterial glass is 0.01-0.8%. The change in the absolute values of each of L*, a*, and b* before and after antibacterial metal ion exchange are such that |△L*| is 0-0.25, |△a*| is 0-0.08, and |△b*| is 0-0.05. The antibacterial effect index R value is greater than 5. Furthermore, the technical solution has a simple and environmentally friendly process, requires a shorter time, and is suitable for industrialized production.
