Technical Field

Background

With the increasing living standard of people, the ceramic tile is one of the indispensable living goods, and the diversification of the functions of the ceramic tile is also receiving more and more attention. The negative ions can reduce the combination of hydrocarbon of formaldehyde, benzene and other hydrocarbons, and decompose the hydrocarbon into pollution-free carbon dioxide and water. For active pollutants such as bacteria and viruses, the negative ions destroy the structure of the pollutants to lose the activity of the pollutants. The negative ion material has piezoelectricity and pyroelectricity, can generate potential difference under the weak fluctuation of external energy to generate an electric field, and generates a partial discharge effect, so that oxygen molecules are charged. The common negative ion materials mainly comprise energy stones such as tourmaline, opal and the like. With the intensive research on negative ions, people begin to apply negative ion materials to ceramic tiles, however, the existing negative ion ceramic tiles have the defects of small release amount and poor durability of negative ions, and due to the limitation of a surface negative ion material layer, the decoration effect is single, so that the requirement of people on the decoration effect of the surface of the ceramic tiles is difficult to meet.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provide an anion luminescent ceramic glaze which has excellent anion release rate and durability and has good luminescent and decorative functions.

The technical scheme adopted by the invention is as follows: the negative ion luminescent ceramic glaze comprises the following raw material components in parts by weight:

specifically, according to the invention, the porous adsorption anion composite powder of fumed silica and diatomite is utilized, so that the structure of the anion powder is effectively prevented from being damaged in the subsequent processing process, and the release rate and durability of anions are effectively improved. Meanwhile, the aluminum oxide, the borax and the strontium carbonate are introduced to synergistically overcome the defect that a long-afterglow luminescent material is difficult to add in the traditional functional ceramic glaze, so that the dispersibility of the long-afterglow luminescent material in the ceramic glaze is improved, the luminous efficiency is improved, and the combination of the luminous performance and the anion release performance is realized.

As a further improvement of the scheme, the negative ion composite powder is formed by mixing rare earth element doped tourmaline materials and Chongguang stone powder in a ratio of 1 (2-5) according to the weight parts of the raw materials. Specifically, the limitation of the invention to the negative ion composite powder is that the different microscopic lattice structures of two negative ion materials are utilized, the performances of generating negative ions under different conditions are different, and the negative ion release performances complement each other, thereby obviously improving the negative ion release rate and the durability.

As a further improvement of the scheme, the particle size of the negative ion composite powder is 10-50 nm. Specifically, the limitation of the particle size of the negative ion composite powder is beneficial to improving the dispersion uniformity of the negative ion composite powder in the glaze.

As a further improvement of the scheme, the specific surface area of the fumed silica is 350-500 g/m²It has good loading effect on nano-scale negative ion composite powder.

As a further improvement of the scheme, the long-afterglow luminescent material is selected from one of aluminate-based long-afterglow luminescent materials, silicate-based long afterglow luminescent materials and phosphate-based long afterglow luminescent materials.

As a further improvement of the scheme, the feldspar is formed by mixing potassium feldspar and albite in a ratio of 2:3 in parts by weight of the raw materials. Specifically, the specific limitation of the feldspar component in the invention is beneficial to reducing the firing temperature of the ceramic glaze.
