Abstract

The invention discloses a low-temperature-fired antique glazed tile and a preparation method thereof, belonging to the field of building materials. The method comprises the following steps: weighing the raw materials of the low-temperature-fired antique glazed tile, adding water for batch mixing and carrying out aging so as to obtain an aged mixture; compacting the aged mixture to form a blank and carrying out demolding so as to obtain a tile blank; subjecting the tile blank to drying and pre-firing so as to obtain a pre-fired tile blank; then carrying out fumigation, cooling and drying so as to obtain a fumigated tile blank; weighing raw materials for a glaze of the low-temperature-fired antique glazed tile and carrying out batch mixing so as to obtain the glaze; coating the surface of the fumigated tile blank with the obtained glaze and carrying out drying so as to obtain a glazed tile blank; and carrying out heating and heat preservation twice and then carrying out natural cooling to room temperature so as to obtain the low-temperature-fired antique glazed tile. The invention has the beneficial effects that the low-temperature-fired antique glazed tile is low in firing temperature, short in firing time, low in energy consumption, high in product density and good in mechanical properties, has excellent application prospects, and is worthy of promotion and application.

Description

technical field [0001] The invention relates to a low-temperature firing antique glazed tile and a preparation method thereof, belonging to the field of building materials. Background technique [0002] Antique glazed tiles are made of high-quality ore raw materials, which are screened and crushed, high-pressure formed, and fired at high temperature. They have good flatness, low water absorption, acid resistance, alkali resistance, and never fade. They are widely used in factories, houses, and hotels. , villas and other industrial and civil buildings. Antique glazed tiles can be made of soft and hard materials such as Daqing, Erqing, cylinder soil, alkaline earth, and purple sand, as well as waste sagger powder and porcelain powder. In addition, coal gangue, coal ash and other mineral waste residues and industrial by-products can also be used to reduce production costs. The preparation of antique glazed tiles is generally to accurately weigh the raw materials according to ...
