Description

Nocturnal rose stone positioning light-transmitting ceramic tile and preparation process Technical Field The invention relates to the field of ceramic tiles, in particular to a night rose stone-like positioning light-transmitting ceramic tile and a preparation process thereof. Background The night rose stone is one of granite, and mainly is produced from Brazil, and has raised leaves, roses and recessed background parts, as in the night rose stone of fig. 1, the glaze color of the night rose stone is particularly raised in the roses, and is a unique precious stone color gradient, and the prior art can only form gray old violet blue with poor color development by wrapping red and sapphire blue or cobalt blue, so that the color gradient of the raised precious stone of the roses cannot be realized. The original stone material of night rose has unique decorative effect, still embodies and presents the printing opacity effect in the protruding department of rose when being shaded at night rose original stone material, like fig. 3 to and the original stone material presents the special bright integrative decorative effect that the protruding department has bright face feel on the stone material detail, and the background concave part presents the matte face feel, like fig. 5. Because the original stone material of night rose has unique decorative effect, the original stone material is mainly used in high-grade places, the stone material has less output and high price, the research on the simulation ceramic tile of the decorative effect of the stone material surface is less in the prior art, and the night rose stone material is difficult to be re-carved by the prior art. Disclosure of Invention The invention aims to provide a preparation process of a night rose stone-like positioning light-transmitting ceramic tile, and the prepared ceramic tile can realize the gradual change of the color of a precious stone with a rose flower bulge of a raw stone material and the unique overall texture effect of the night rose stone, including the light-transmitting effect at the rose flower bulge and the light-dummy integrated decorative effect during backlight. In order to achieve the aim of the invention, the invention provides a preparation process of a night rose stone positioning light-transmitting ceramic tile, which comprises the following steps: S1, preparing a light-transmitting blank with light transmittance more than or equal to 0.45% after firing, and then stamping by using a concave-convex texture die to prepare a light-transmitting blank with leaf protrusions, rose protrusions and background recesses; S2, sequentially applying a known basic overglaze to the transparent blank body and performing ink-jet printing to form a pattern layer corresponding to the concave-convex texture of the transparent blank body; S3, distributing various colored dry particles at the rose convex positions of the pattern layer, applying the flash dry particles with flash effect after firing at the background concave positions of the pattern layer to obtain the pattern layer with the dry particles distributed, and distributing the colored dry particles and the flash dry particles through a silk screen; s4, applying a matte protective glaze on the pattern layer; S5, sintering in a kiln once, and polishing to obtain the night rose-like stone positioning light-transmitting ceramic tile. The invention prepares a light-transmitting green body with concave-convex textures by optimizing light-transmitting green body powder with the light transmittance of more than 0.45 percent after firing, preparing the light-transmitting green body with concave-convex textures by stamping, forming a pattern layer corresponding to the concave-convex textures by ink jetting, forming a plurality of colored dry particles to be interspersed at the concave part of the rose of the pattern layer, forming a matte surface with a sparkling sandstone effect by applying the sparkling dry particles at the concave part of the pattern layer and then applying the matte protection glaze to fire and polish to obtain the night rose stone-like positioning light-transmitting ceramic tile, and imitating the unique overall texture effect of the night rose raw stone. Preferably, in step S2, the base overglaze is applied by spraying, which is conducive to obtaining the base overglaze with uniform thickness on the uneven light-transmitting blank, and further preferably, the base overglaze at the raised positions of the roses is removed after the base overglaze is applied, which is conducive to improving the light-transmitting effect. Preferably, the light transmittance of the light-transmitting green body after firing is 0.45-1.5%, and the light-transmitting effect of the prepared night rose-imitating ceramic tile and the night rose raw stone is closest to each other within the preferred range. Specifically, the preparation method of the mould with the concave-convex texture comprises th
