Abstract

The invention discloses a preparation method of an acid-resistant and freeze-resistant coal ash glazed tile. The glazed tile which has acid resistance and freezing resistance, high anti-pressure ability and low water absorption is prepared from the following raw materials: 60-80 parts of coal ash, 10-20 parts of clay, 4-5 parts of barium carbonate, 4-5 parts of limestone, 1-2 parts of sodium tripolyphosphate and 1-2 parts of cellulose by a method for sintering and intensifying a glazed green body twice; the preparation method is simple in process, cheap in raw material and beneficial to industrialization.

Description

technical field [0001] The invention belongs to the field of glazed tile manufacture, in particular to a method for preparing an acid-resistant and freeze-resistant fly ash glazed tile. Background technique [0002] Glazed tiles, radiant and colorful, are traditional Chinese building components. They are usually painted with colored lead glazes such as golden, emerald green, and blue. Because of their solid materials, bright colors, and smooth glazes, they have always been the favorite among architectural ceramic materials. China used glazed tiles as decorations in buildings as early as the Southern and Northern Dynasties. In the Yuan Dynasty, the imperial palace buildings used glazed tiles on a large scale. The Ming Tombs and Nine Dragon Walls are masterpieces in the history of glazed tile architecture. [0003] With the development of science and technology and the improvement of people's living conditions, the glazed tiles originally used by nobles have gradually entered ...
