AI Technical Summary

Problems solved by technology

With people's in-depth research on negative ions, people began to apply negative ion materials to ceramic tiles. However, the existing negative ion ceramic tiles not only release less negative ions and have poor durability, but also have a single decorative effect due to the limitation of the surface negative ion material layer. , it is difficult to meet people's requirements for the surface decoration effect of ceramic tiles

Abstract

The invention discloses a negative ion luminescent ceramic glaze which comprises the following raw material components in parts by weight: 40-55 parts of feldspar, 20-30 parts of quartz sand, 15-25 parts of kaolin, 1-2 parts of bentonite, 10-15 parts of a negative ion composite material, 3-5 parts of fumed silica, 20-30 parts of diatomite, 2-4 parts of a long afterglow luminescent material, 8-12 parts of aluminum oxide, 5-12 parts of borax, and 3-6 parts of strontium carbonate. According to the invention, the porous structure of fumed silica and diatomite is utilized to adsorb the negative ioncomposite powder; the negative ion composite powder is effectively prevented from being corroded in the high-temperature sintering process; the release rate and durability of negative ions are greatly improved, the release rate of the negative ions on the surface of the formed glaze layer is 1300-1800 / cm<3>, and meanwhile, aluminum oxide, borax and strontium carbonate are introduced to improve the luminescent efficiency of the long-afterglow luminescent material, so that the long-afterglow luminescent material has a good luminescent decoration function.

Description

technical field [0001] The invention relates to the field of ceramic glazes, in particular to a negative ion luminescent ceramic glaze. Background technique [0002] With the improvement of people's living standards, ceramic tiles, as one of the indispensable daily necessities, have attracted more and more attention for their diversified functions. Negative ions can reduce the combination of hydrocarbons such as formaldehyde and benzene, allowing them to be decomposed into pollution-free carbon dioxide and water. For active pollutants such as bacteria and viruses, negative ions destroy their structure and make them inactive. Negative ion material is a kind of piezoelectric and pyroelectric, which can generate potential difference under the weak fluctuation of external energy, generate electric field, and appear partial discharge effect, so that oxygen molecules are charged. Common negative ion materials mainly include energy stones such as tourmaline and opal. With people...
