Method for antibacterial lead-free low temperature frit and preparing method thereof

Abstract

The invention discloses a method for antibacterial lead-free low temperature frit and a preparing method thereof. The method comprises the steps of: A mixture: mixing and grinding evenly 10-18% of quartz 5-12% of feldspar 15-25% of borax 3 -12% of carbonate, 20 - 35% of boric acid, 3- 8% of spodumene, 1 - 4% of fluorinated salt, 0 - 5% of kaolin, then adding 0.1-5% of antibacterial composite afterwards, grinding evenly the mixture, so that the finished product is obtained; B melting, C molding and cooling. Compared with prior low temperature frit, the method has the advantages that the ingredients of the low temperature frit are scientific, the preparing steps are reasonable, the performance is stable, and no toxic substances such as lead and cadmium are in the frit, meanwhile, the frit has an antibaterical property with persistent spectra and an antifouling self-cleaning function, which broad further the application sphere for the low temperature frit. The frit can be used as raw materials to produce rich building materials,such as antibacterial mosaic, antibacterial microcrystalline ceramic composite panels, antibacterial low temperature ceramic ink and the like.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to an antibacterial lead-free cadmium low-temperature frit and a preparation method thereof. Background technique [0002] Bacteria and mold, as pathogenic bacteria, are very harmful to humans, animals and plants, affecting people's health and even life-threatening, and bringing significant economic losses. Therefore, the research on antibacterial materials and their products has attracted people's attention day by day, and the demand for antibacterial products will constitute a huge market. [0003] Wall tiles, no matter for home interior decoration, industrial production or public places, how to make them have more functions related to people's health protection in addition to satisfying the appearance and practicality is also a benchmark for scientific researchers in the industry to follow the trend of the times and life and made thinking. [0004] In the existing building dec...

Problems solved by technology

However, in order to reduce the temperature of the traditional low-temperature frit, a large amount of chemical substances containing lead and cadmium are used. Although the effect of reducing the melting temperature can be achieved, the chemical substances of lead and cadmium are highly toxic.

At the same time, there are few reports on the low-temperature frit with antibacterial function. If an antibacterial agent is simply added, the antibacterial stability will be weakened due to the high-temperature melting process, and the antibacterial effect may even be lost.
