Abstract

The invention discloses a preparation method of an acid-proof freezing-tolerant gangue glazed tile. The acid-proof freezing-tolerant gangue glazed tile is prepared from such raw materials as 65-95 parts of gangue, 10-20 parts of aedelforsite, 3-6 parts of potassium feldspar, 3-6 parts of limestone, 1-2 parts of lithium carbonate and 1-2 parts of cellulose; the acid-proof freezing-tolerant glazed tile high in stress tolerance and low in water absorption can be prepared from a glazed green body by use of a method of twice sintering and twice strengthening; and the preparation method is simple in process, cheap in raw materials, and advantageous for 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 coal gangue 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 ente...
