The invention discloses a building
ceramic tile with a fluorescent magical
color effect and a preparation method of the building
ceramic tile, and relates to the technical field of building
ceramic tiles. The ceramic tile sequentially comprises a
green body layer, a cover
glaze layer, a pattern layer, a fluorescent material layer and a transparent color-emitting
glaze layer from bottom to top, the pattern layer is formed by printing a multi-layer multicolor pattern file on the cover
glaze layer by using a
digital ink jet
machine; according to the fluorescent material layer, after patterns are printed in an ink-jet mode, a printing
machine is used for accurately aligning designed marking positions, the patterns printed by an ink jet printer and the fluorescent material
layers with different colors are positioned and overlapped, it is ensured that the patterns of the fluorescent material layer and the colorful patterns printed by the
digital ink jet printer are completely matched and overlapped, and the multi-layer colorful effect of the
brick surface is achieved. According to the invention, a fluorescent material is introduced, a novel transparent color-developing protective glaze is researched and developed, and a proper firing process is combined, so that the
brick surface can show a magical
color effect in both bright and dark places.
