Process for producing ceramic tile with uneven surface

Abstract

The invention discloses a process for producing a ceramic tile with uneven surface. The process comprises the following steps: (1) blank, over glaze and fancy glaze are prepared; (2) the blank is molded into a blank tile in a mould tile, wherein uneven grains with depth of between 1.0 and 2.5mm are formed in the mold tile, and the pressure for molding the blank is between 3,300 and 3,700MPa / cm<2>; (3) the molded blank tile is sintered and dried, wherein the sintering temperature is between 1,170 and 1,200 DEG C; (4) the glaze is poured on the dry tile, wherein the flowability of glaze slurry is between 30 and 40S / 100M<1>, the fluctuation is between 0 and 5S, the specific gravity of the glaze slurry is between 170 and 190g / cm<2>, and the quantity of the glaze is between 0.01 and 0.08g / cm<2>; (5) the fancy glaze is printed by a soft roll, wherein the proportion between pigment and water in the fancy glaze is between 1.37 and 1.45, the rotating speed of the soft roll is matched with thatof a tile conveying belt, and is set to be 30 to 40m / min; (6) sintering the tile in a kiln, wherein the sintering temperature is between 1,090 and 1,110 DEG C; and (7) trimming. By the process for producing the ceramic tile with uneven surface, the produced ceramic tile with uneven surface has good printing visual effect on the uneven surface, and has strong three-dimensional sensation.

Description

technical field [0001] The invention relates to the field of architectural ceramics, in particular to a production process for surface concave-convex ceramic tiles. Background technique [0002] There are three main ways to realize the pattern of ceramic decorative tiles: one is screen printing technology; the other is roller printing technology; the third is inkjet printing technology. The screen printing technology converts the designed pattern into the hollow dots on the mesh cloth with photosensitive glue of uniform thickness, and the flower glaze prepared with basic glaze and coloring material forms a corresponding pattern on the brick surface through the mesh plate. Roller printing technology, the designed pattern is engraved on the blank rubber roller by laser, and the flower glaze cloth prepared with roller printing oil and coloring material is placed on the rubber roller, and the rubber roller passes the brick surface while printing the flower glaze. Print on the b...

Problems solved by technology

[0003] When using screen printing technology to express patterns on surface concave-convex tile products, patterns can only be displayed on the raised surface of the product, and patterns cannot be printed on the concave surface; inkjet printing equipment is relatively expensive, and the surface flatness of its products is poor ; Ordinary rubber roller printing technology is easy to cause some positions to be unable to express when performing pattern expression on surface concave-convex tile products, and the life of the rubber roller is greatly shortened
