Abstract

The invention discloses an anti-radiation lead and cadmium free low temperature frit and a preparation method thereof. The preparation method comprises the steps of: A material mixing: mixing 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 and performing grinding, then adding 0.1-5% of an antibacterial compound and 10-15% of an anti-radiation compound, and grinding the materials evenly 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 characteristics of scientific compounding, reasonable preparation, and stable performance, does not contain lead, cadmium or other extremely toxic substances, also has lasting spectral antimicrobial characteristics, antifouling and self-cleaning functions and anti-radiation performance, thus further broadening the application scope of the low temperature frit. The low temperature frit can be employed as the raw material to manufacture rich building materials, like anti-radiation and antibacterial mosaics, anti-radiation and antibacterial microcrystalline ceramic composite plates, anti-radiation and antibacterial low-temperature ceramic ink, etc.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a radiation-proof 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] With the advancement of science and technology and the rapid development of the information industry, equipment or systems such as computers, mobile phones, fax machines, telephones, and networks have been widely used in the processing of information generation, transmission, reception, and storage. This type of equipment is inseparable from the action of electromagnetic waves when w...
