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 about multifunctional low-temperature frits such as antibacterial and photochromic, and the existing technology still needs to be improved and developed.

Abstract

The invention discloses a lead and cadmium free low temperature frit and a preparation method thereof. The preparation method comprises the steps of: A. material mixing: mixing and grinding 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 fluoride salt, and 0-5% of kaolin evenly, then adding 1-5% of an antibacterial compound, 3-8% of a negative ion compound and 1-10% of a photochromic compound, grinding the substances uniformly to obtain a mixture; B. melting; and C. molding and cooling. Compared with existing low temperature frits, the low temperature frit prepared by the method provided by the invention has the advantages of scientific compounding, reasonable preparation, stable performance, and no lead, cadmium or other extremely toxic substances. Through reasonable collocation of the photochromic compound, the negative ion compound and the antibacterial composite material, the frit has excellent antibacterial, air purification and photochromic properties, and the application scope of the low temperature frit is further broadened. Therefore, the low temperature frit can be used as the raw material to manufacture rich building materials.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a lead-cadmium-free 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] Photochromism refers to photochromism caused by different light sources and color changes caused by physical phenomena such as reflection, refraction and interference. Photochromic materials are divided into organic photochromic materials and inorganic photochromic materials, among which inorganic photochromic materials are less studied, mainly including transition metal oxides, metal halides and ra...
