Noctilucent antibacterial lead and cadmium-free low-temperature frit and preparing method thereof

Abstract

The invention discloses an noctilucent antibacterial lead and cadmium-free low-temperature frit and a preparing method thereof. The method comprises the steps of: A mixing: 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 and 0 - 5% of kaolin, adding 0.1-5% of antibacterial composite and 1 to 5% of noctilucent powder composite, grinding evenly to prepare a mixture; b melting, and c cooling for molding. Compared with the conventional low-temperature frit, the low-temperature frit prepared by the method has the advantages of scientific ingredients, reasonable preparation, stable performance and no toxic substances, such as lead and cadmium, meanwhile, the frit has the persistent antibaterical property of spectra, the antifouling self-cleaning function and the noctilucent function, does not have agglomeration and is high in uniformity and stability of luminance and antibacterial stability, which further broads the application range of the low-temperature frit. The frit can be used as raw materials to manufacture rich building materials,such as noctilucent antibacterial mosaic, noctilucent antibacterial microcrystalline ceramic composite panels and noctilucent antibacterial low-temperature ceramic ink.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a luminous 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] Long afterglow luminescent materials are commonly known as luminous powder. There are unsaturated energy levels in their electronic structure. Under light conditions, photon energy is absorbed to make electrons undergo energy level transitions. In a darker environment, the energy absorbed by electrons will be released. Creates a fluorescent effect. At present, long-lasting lu...

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 low-temperature frits with antibacterial and luminous functions; moreover, low-temperature frits are not suitable for direct addition of antibacterial agents and / or long-lasting luminescent materials, due to the high temperature environment and easy agglomeration to cause luminescence and antibacterial effects bad question
