Abstract

The invention discloses a fine dry granule glaze, which comprises in parts by weight: 5-15 parts of fine dry granules, 35-50 parts of glue, and 35-50 parts of glaze slurry; wherein, the chemical composition of the fine dry granules is: SiO 2 29~33%, Al 2 o 3 45-52%, Fe 2 o 3 1~2.35%, TiO 2 0.2~0.5%, CaO 0.6~1.5%, MgO 0.8~1.7%, K 2 O 2~4.5%, Na 2 O 1.5-2.0%, ZnO 1.8-2.6%, BaO 0.5-1.0%, LOI 4-6.5%; the particle size of fine dry particles is ≤250 mesh. Correspondingly, the invention also discloses a fine dry grain ceramic brick and a preparation method thereof. The invention greatly reduces the particle size of the dry particles in the fine dry particle glaze, so that the brick surface is not easy to hide dirt. At the same time, the decorative effect of the fine dry glaze of the present invention is outstanding, 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 ...
