Embodiment 1

[0047] A method for preparing glazed tiles with a bright star effect on the surface, comprising the steps of:

[0048] a. Calculated in parts by weight, the raw materials in the frit include the following components: 12 parts of calcite, 15 parts of barium carbonate, 36 parts of potassium feldspar, 6 parts of zinc oxide, 15 parts of kaolin, 4 parts of calcium borate, 2 parts of soda ash, 10 parts of quartz sand, weighing raw materials. After the raw materials are mixed, they are put into the frit furnace to be calcined and melted at 1450°C, and then flow out of the frit furnace and quenched into frit particles for later use.

[0049] Calculated by mass percentage, the chemical composition of the frit is: SiO 2 50.6%, Al 2 o 3 11.4%, MgO 0.35%, CaO 8.9%, Na 2 O is 1.5%, K 2 O is 4.5%, BaO is 13.3%, ZnO is 6.5%, B 2 o 3 2.2%, TiO 2 0.1%, Fe 2 o 3 It is 0.2%, and the balance is loss on ignition.

Abstract

The invention relates to the technical field of ceramic tiles, and particularly discloses a glazed tile with a bright star effect on the surface and a preparation method of the glazed tile. The preparation method comprises the steps of applying ground glaze on a green brick, applying matte glaze, printing, applying bright star glaze and sintering; by adjusting the components and content of the matte glaze, the matte glaze forms a large number of glass phases, which is beneficial for forming a compact matte glaze layer; the high-sodium-content bright star glaze can remarkably reduce the melting temperature, the surface tension and the high-temperature viscosity of the bright star glaze, is matched with the matte glaze to enable the bright star glaze to be leveled in a matte glaze layer, is high in density, facilitates improvement of the antifouling property of the bright star glaze layer, and is low in cost and easy to popularize. The glaze surface of the fired glazed tile has the effect of sparkling star light, the flatness of the glaze surface is high, the glaze surface does not need to be polished, and the process is simple.

Description

technical field [0001] The invention relates to the technical field of ceramic tiles and a preparation method thereof, in particular to a glazed tile with a bright star effect on the surface and a preparation method thereof. Background technique [0002] Silver star stone is a kind of stone that can show the unique effect of starlight on the surface under the light. Therefore, the ceramic industry has begun to imitate the above-mentioned starlight effect on glazed tiles. The commonly used methods are: screen printing on the surface of the tile. Printing convex glaze, sprinkle dry granules, etc., although the above methods can achieve a certain sparkling effect, but there are the following defects: for example, after printing flash glaze and convex glaze on the brick surface, the regularity of the star sparkling is too strong and lacks naturalness. The effect of the sparkling stars floating on the glaze reduces the fusion of the silver star dry particles and the glaze, and th...
