Example Embodiment

[0018] Example 1

[0019] A preparation method for adding rare earth water-soluble antibacterial ceramic glaze. In a reactor, 30g ammonium hexafluorozirconate, 3g sodium hexametaphosphate, 45g zinc hexafluorosilicate, 13g ammonium fluoroborate, 2g silver nitrate are respectively added to the reactor, 7g of lanthanum nitrate is ground and mixed evenly to add rare earth water-soluble antibacterial ceramic glaze. The obtained rare earth water-soluble antibacterial ceramic glaze should be packaged with plastic products and sealed and moisture-proof. Its use method: dissolve this rare earth water-soluble antibacterial ceramic glaze in water, saturated solution, spray the solution of rare earth water-soluble antibacterial ceramic glaze evenly on the ceramic green body with a sprayer, and fire it at a high temperature of 950℃ To the finished product.

Abstract

The invention discloses a preparation method of a rare-earth-added water-soluble antibacterial ceramic glaze. The preparation method is characterized by comprising the following technical steps: in a reactor, adding, by mass, 25-35% of ammonium hexafluorozirconate, 2-5% of sodium hexametaphosphate, 40-50% of zinc silicofluoride, 8-18% of ammonium fluoroborate, 2-6% of silver nitrate, and 5-15% of lanthanum nitrate, wherein the sum of each component is 100%; and performing grinding for uniform mixing to obtain the rare-earth-added water-soluble antibacterial ceramic glaze. A use method of the rare-earth-added water-soluble antibacterial ceramic glaze comprises: dissolving the rare-earth-added water-soluble antibacterial ceramic glaze in water to prepare a saturated solution; uniformly spraying the solution of the rare-earth-added water-soluble antibacterial ceramic glaze onto a ceramic biscuit by a sprayer; and baking the ceramic biscuit at a high temperature of 950-1000 DEG C to obtain a finished product. The ceramic glaze has excellent bactericidal activity and good glossiness.

Description

technical field [0001] The invention belongs to the technical field of daily-use ceramics, and in particular relates to a preparation method of rare earth-added water-soluble antibacterial ceramic glaze. Background technique [0002] Bacteria, mold (fungi) are very harmful to people's life as pathogenic bacteria, have had a strong impact on people's health. Humans have been using antibacterial things for a long time, from the tar, frankincense, and cinnamon used by the Egyptians in BC to the synthesis of urea by Weller in 1828. In the 20th century, people have mastered the chemistry of pesticides fish, ketones, and pyrethrins. After the structure, a large number of organic antibacterial agents were born. In the 1950s, the development of antibacterial agents and antibacterial technology gradually developed. In the 1980s, people began to pay attention to the quality of life and pursue a comfortable and hygienic living environment. Antibacterial and deodorant fibers were made...
