Along with the iterative upgrade of the technology, the rapid development of the building ceramic tiles is realized, products with various colors and technologies overlapped from antique bricks with small specifications to large-specification rock boards in the modern fashion whole industry are obtained, a great selection space is provided for consumers, and the home environment is greatly improved. Due to the improvement of the product requirements of consumers, the public not only focuses more and more on the texture of the surface of the ceramic tile, but also pursues more and more on the aspects of art and culture. At present, pattern design materials of architectural ceramics are mostly from marble, jade, sandstone and cement, and are rarely from Chinese traditional porcelain, and the alluvial gold glaze is mainly presented in Chinese traditional artistic ceramic products, but is not presented on the architectural ceramic products at present.
The alluvial gold glaze belongs to one of crystal glazes, is a black glaze from the Han Dynasty, and the main color of the black glaze is that the alluvial gold crystal is suspended in a glaze layer after being sintered because the black glaze contains a large amount of ferric oxide and the glaze layer is thick. The crystal in the alluvial gold glaze artistic ceramic is usually ferric oxide crystallization, generally considered as a golden red and flashing crystal formed by firstly dissolving ferric oxide in glaze at high temperature and forming supersaturated solution of iron, then precipitating ferric oxide crystal, and slowly burning, insulating, slowly cooling and crystallizing glaze, wherein the sintering mode of the alluvial gold glaze is completely different from the traditional fast sintering of building ceramic tiles, if a crystallization effect is required to be generated, slow sintering and slow cooling are required, the period reaches more than 12 hours, perfect crystallization glaze can be sintered, the sintering of the building ceramic tiles is generally within 1 hour, and the crystallization of the alluvial gold glaze is difficult to realize under the existing conditions for producing the building ceramic tiles.
The invention provides a alluvial gold glaze ceramic tile and a preparation method thereof, aiming at solving the problem of how to prepare an alluvial gold glaze ceramic tile product with alluvial gold crystals on the glaze surface under the condition of quick firing.
Disclosure of Invention

In order to achieve the purpose, the invention adopts the technical scheme that: a alluvial gold glaze ceramic tile comprises a blank layer, a ground glaze layer, an ink-jet pattern layer, a process effect layer and a protective glaze layer from bottom to top in sequence; the preparation raw materials of the process effect layer comprise placer gold crystals and placer gold glaze; the preparation raw materials of the alluvial gold crystal comprise, by weight: 2-5 parts of albite, 1-3 parts of kaolin, 0.1-0.5 part of strontium carbonate, 85-90 parts of ferric oxide, 0.5-1 part of titanium oxide, 0.5-1 part of barium carbonate, 0.5-1 part of manganese dioxide and 1-2 parts of calcined talc; the preparation method of the alluvial gold glaze comprises the following steps of: 40-48 parts of albite, 5-6 parts of kaolin, 3-6 parts of potassium feldspar, 3-6 parts of fluorite, 18-25 parts of ferric oxide, 2-5 parts of quartz, 6-8 parts of calcite, 2-6 parts of wollastonite and 1-2 parts of calcined talc.
The technological effect is applied to the ceramic tiles in the field of construction, and the main difficulty is that the iron sesquioxide is difficult to crystallize in the glaze and form placer gold crystals under the condition of quick firing of the conventional ceramic tiles. In order to solve the technical problem, the invention provides the alluvial gold glaze ceramic tile, which is prepared by preparing alluvial gold crystals and alluvial gold glaze firstly and mixing the alluvial gold crystals and the alluvial gold glaze to prepare the technological effect layer of the alluvial gold glaze ceramic tile, so that the alluvial gold glaze ceramic tile can be prepared under the conditions of the existing production of building ceramic tiles. In addition, in order to ensure that the placer gold crystals are complete and are not melted in the glaze when the placer gold crystals are added into the glaze for glaze firing, a special placer gold glaze is needed to keep the shape, size and color of the placer gold crystals stable; the special alluvial gold glaze is different from other glazes in formula, contains a large amount of ferric oxide, forms a common phase with alluvial gold crystals during firing, and ensures that the alluvial gold crystals are not dissolved in the glazes, thereby maintaining the integrity of the shape and size of the alluvial gold crystals.
