Ceramic tile with bulged particle effect and preparation method of ceramic tile

Abstract

The invention relates to a ceramic tile with a bugled particle effect and a preparation method of the ceramic tile. The method comprises the steps of applying cover glaze with a specified formula to a blank body, wherein the sintering temperature of the cover glaze is more than 1120 DEG C, and by weight percent, the cover glaze comprises more than 57% of SiO2 and more than 22% of Al2O3; applying dry granular glaze slurry to the blank body coated with the cover glaze through a linear glaze sprayer, wherein the specific gravity of the dry granular glaze slurry is 1.27-1.38g / mL.

Description

technical field [0001] The invention relates to the technical field of ceramic tile production and manufacturing, in particular to a preparation technology of ceramic tiles with convex effects produced by using a linear glazer to drench dry particles. Background technique [0002] The three-dimensional effect and wear-resistant and anti-skid performance of ceramic tiles have attracted more and more attention from the society, and the preparation of ceramic tiles with raised particle effects is one of the hot spots in the preparation of ceramic tiles. [0003] At present, there are usually three methods for preparing ceramic tiles with raised particle effects: 1) using a concave-convex mold; 2) throwing or dotting on the surface of the adobe; and 3) applying dry particles on the surface of the adobe. For method 1), when producing planar products and concave-convex products, it is necessary to replace the molds on the production line, which affects the production progress, and...

Problems solved by technology

For method 1), when producing flat products and concave-convex products, it is necessary to replace the molds on the production line, which affects the production progress, and this method needs to be equipped with various concave-convex molds, which is costly

For method 2), the dots produced by ordinary flicking dots or screen printing often do not work well

For method 3), it is usually completed by dry granule sprinkling and fixing liquid. The dry granule pattern formed by this method has a single color, poor three-dimensional effect, and uneven cloth, which is prone to surface defects.

[0004] In addition, the inventors also noticed that the dry granules are applied on the surface of the adobe and then fired. During high-temperature firing, the surface glaze often melts and collapses, which leads to the melting of the dry granules into the surface glaze, and the final dry granules are ineffective.
