Abstract

The invention discloses a fine dry grain glaze. The fine dry grain glaze comprises, by weight, 5-15 parts of fine dry grains, 35-50 parts of glue and 35-50 parts of a glaze slip, wherein the chemicalcomponents of the fine dry particles comprise 29-33% of SiO2, 45-52% of Al2O3, 1-2.35% of Fe2O3, 0.2-0.5% of TiO2, 0.6-1.5% of CaO, 0.8-1.7% of MgO, 2-4.5% of K2O, 1.5-2.0% of Na2O, 1.8-2.6% of ZnO, 0.5-1.0% of BaO and 4-6.5% of LOI; and the granularity of the fine dry particles is less than or equal to 250 meshes. Correspondingly, the invention further discloses a fine dry grain ceramic tile anda preparation method thereof. The particle size of the dry particles in the fine dry particle glaze is greatly reduced, so that the brick surface is not prone to hiding dirt. Meanwhile, the fine dry granular glaze is outstanding in decorative effect, and the brick surface has a dazzling metal aperture under light irradiation.

Description

technical field [0001] The invention relates to the technical field of ceramic bricks, in particular to a fine dry grain ceramic brick, a preparation method thereof, and a fine dry grain glaze. Background technique [0002] With the development of ceramic tile technology, people's requirements for the functional and decorative performance of ceramic tiles are increasing day by day. As far as functionality is concerned, anti-slip and stain resistance are the main directions of concern at present. For decoration, the luster and pattern of ceramic tiles are the main directions of attention. In this context, "dry granules", as a new means of decoration and functionalization, are gradually being applied in the production process of ceramic tiles. [0003] Dry granules are essentially a special kind of frit; dry granules have been applied many times during the development of ceramic tiles. For example, at the beginning of the 20th century, the microcrystalline brick introduced ...
