A kind of ceramic dry glaze, crystal diamond flashing ceramic tile and preparation method thereof

Abstract

The invention belongs to the technical field of architectural ceramics, and specifically discloses a ceramic dry granular glaze, crystal diamond flashing ceramic brick and a preparation method thereof. The raw materials of the ceramic dry glaze include zirconium-containing transparent frit dry particles and zircon sand, and the zirconium source of the zirconium-containing transparent frit dry particles is zirconium oxychloride. The crystal diamond flashing ceramic tile includes a body layer and a surface glaze layer, and the surface glaze layer is fired from ceramic dry glaze. The present invention uses zirconium-containing transparent dry granule glaze as the basic glaze, and by adding zircon sand particles, because there is a small amount of evenly distributed zirconium in the zirconium-containing transparent dry granule glaze, the zirconium in the glaze melt is in a molten and saturated state, which can effectively prevent The high temperature melting of the extra zircon sand particles in the glaze melt. At the same time, the zirconium silicate crystals formed during the cooling process of the zirconium-containing transparent dry glaze use zircon sand particles as the crystallization carrier, so that the zircon sand particles grow further, and the crystal shape is more angular, making the prepared ceramics Dry-grain glazes can exhibit a diamond-like sparkle effect under light conditions.

Description

technical field [0001] The invention belongs to the technical field of architectural ceramics, and in particular relates to a dry ceramic glaze, crystal diamond flashing ceramic brick and a preparation method thereof. Background technique [0002] As a building decoration material, natural stone is favored by consumers due to its rich patterns, colors and line textures. However, as a non-renewable resource, natural stone is gradually restricted in its exploitation. The emergence of ceramic inkjet printing technology makes the ceramic tiles imitating natural stone effect more and more realistic. However, the flash effect of special natural stone is difficult to express with ceramic tile technology. [0003] At present, there are mainly three preparation methods with flashing effects: the first is to use dry granules of glazes with different particle sizes and different high temperature resistance combined with semi-polished technology to achieve the flashing effect on the s...

AI Technical Summary

Problems solved by technology

Among the above methods, the first kind of flash point is on the surface of the glaze layer, which lacks three-dimensionality and layering, and the decorative effect is not good

The second type of flash-resistant mica has very few types, and the color is mostly golden and silver, which is relatively simple, and the erosion of the high-temperature glaze layer melt will cause the flashing effect of flash mica to be greatly reduced

The flashing dry glaze prepared by the first method has long-term high-temperature melting of the zircon sand, and part of the edges and corners of the zircon sand particles are melted, resulting in a greatly reduced flashing effect of the glaze prepared by using the flashing dry glaze, and is prone to flashing effects unstable problem

The flash glaze prepared by the second method is due to the addition of zircon sand particles, and the fusion degree of the zircon sand particles and the glaze is relatively poor. Cracks, easy to hide dirt on the surface, unnatural flashing effect on the glaze surface, and some edges and corners of the zircon sand are also melted during high-temperature firing, resulting in poor flashing effect
