Problems solved by technology

The main reason is that under high temperature conditions, the luminescent powder in the glaze is easily eroded by the high-temperature flux, which destroys the internal structure of the luminescent powder and causes the luminescent powder to fail.
In addition, since the synthesis temperature of luminescent powder is generally above 1300°C, the luminescent powder has high refractoriness and is not easy to be melted and flattened in the glaze layer, resulting in uneven glaze surface.
Therefore, luminescent powder has not been applied in high-temperature ceramic glazed tiles

Abstract

The invention discloses a luminescent ceramic glazed tile, which comprises a green body layer, a ground glaze layer, a fancy glaze layer, a luminous layer and a glaze polishing layer from the bottom up. The luminous layer is composed of luminescent powder with grain fineness of 80-120 meshes. According to the invention, the luminous layer is independently arranged between the fancy glaze layer andthe glaze polishing layer, coarse grain luminescent powder with appropriate granularity is adopted as the raw material, luminescent properties inside the luminescent powder can be ensured after corrosion of the coarse grain luminescent powder surface layer, and the problem that a high temperature flux easily erodes the traditional luminescent powder and destroys the internal structure of luminescent powder, and results in luminescent powder failure can be overcome. The invention also discloses a preparation method of the luminescent ceramic glazed tile, the method has the advantages of simple process and strong controllability, also can perform mild polishing treatment on the surface of the ceramic glazed tile in virtue of the high refractoriness of luminescent powder, makes the coarse grain luminescent powder have the characteristics of anti-skid particles, and endows the luminescent ceramic glazed tile with anti-skid function.

Description

technical field [0001] The invention relates to the field of architectural ceramics, in particular to a functional ceramic. Background technique [0002] With the continuous improvement of living standards, people have higher and higher requirements for architectural ceramics, not only pursuing their practicability, but also paying more and more attention to their decoration and functionality. Luminescent ceramic tiles introduce afterglow luminescent materials into ceramic tiles, so that after absorbing external energy, the ceramic tiles have the characteristics of continuous luminescence under dark conditions. Luminous ceramic tiles can be widely used in stairs, aisles and public places with a lot of traffic, so that they can be used as light sources or guides in case of power failure or emergency. Due to the poor luminescence performance of luminescent materials at high temperature, the current luminescent ceramic tiles are mainly concentrated in low-temperature ceramic t...
