Abstract

The invention discloses a manufacturing method of a glazed ceramic exterior wall tile, and relates to the technical field of building material production. The glazed ceramic exterior wall tile is prepared from the following raw materials by weight percent: 25-30% of clay, 25-35% of Tongfu soil, 20-22% of gravel stone and 20-25% of potassium sand; the total aluminum content of the glazed ceramic exterior wall tile is 14.5-18%, and the total iron content of the glazed ceramic exterior wall tile is less than or equal to 2%. The manufacturing method comprises the steps of adding water into the raw materials, wherein the amount of the water is 10% of the total amount of the raw materials, carrying out ball-milling, then deironing and sieving, carrying out spray drying to obtain granules, and staling for 48h or more; pressing a green body under the pressure of 180-230MPa, and drying to obtain a green tile with the water content of 0.5-1%; spraying glaze water onto the surface of the green tile, then putting the green tile into a roller kiln, drying at a temperature region of 200-400 DEG C, and then sending to a temperature region of 1210-1220 DEG C for sintering until the water absorption of a tile body is 1-3%, so as to obtain the glazed ceramic exterior wall tile. The manufacturing method provided by the invention solves the problems that a glazed ceramic exterior wall tile manufactured by the existing production technology is high in water absorption, and is not wear-resistant, pressure-resistant and cold-resistant.

Description

technical field [0001] The invention relates to the technical field of building material production, in particular to a method for producing exterior wall tiles. Background technique [0002] Glazed ceramic exterior wall tiles are exterior wall tiles composed of adobe and glazed surface. The glazed surface is glazed and fired on the surface of the adobe, which can obtain rich decorative effects, and it is antifouling, easy to clean, and does not require special Nursing and other advantages, and thus widely favored by consumers. The existing glazed ceramic exterior wall tile is made of clay, quartz sand and other inorganic non-metallic raw materials, which are produced by batching, ball milling, spray drying, pressing, firing green body, spraying glaze, glaze firing and other processes. , this process includes two firings, the temperature of the first firing of the biscuit is 800-900°C, the second firing is the glaze firing after spraying the glaze, and the glaze firing temp...
