Problems solved by technology

However, its sintering temperature is 1160-1170°C, which is high energy consumption and pollutes the environment. It is not suitable for the development of future economic strategies. Therefore, from the perspective of energy conservation and the country, future development must be low-temperature sintering, energy conservation and environmental protection.

Abstract

The invention relates to a method for preparing low-sintering glazed tile by using lead-zinc-silver mine tailings. The composition of glazed tile green body and glaze is optimized; the lead-zinc- silver mine tailings, bauxite and mullite are used as main materials for the green body; chrome-tin purple material, cryolite and mullite are used as main raw materials for glaze; additives capable of reducing the sintering temperature of green body and glaze including nano alumina, titanium dioxide, Ca3(VO4)2, zinc oxide, potassium carbonate, sodium tetraborate decahydrate are employed to reduce the sintering temperature of the glazed tile to 600-730 DEG C, so as to form glaze and obtain the glazed tile. At the same time, the prepared glazed tile has good crystallization effect and the physicochemical performance such as overpressure resistance met the application requirements.

Description

technical field [0001] The invention belongs to the field of glazed tile preparation, in particular to a method for preparing low-fired glazed tiles by using lead-zinc-silver mine tailings. Background technique [0002] Glazed tile is an ancient and traditional ceramic material in my country. With the development of tourism, people's demand for glazed tiles is also increasing, and their requirements are also getting higher and higher. [0003] Existing glazed tiles are usually made by mixing and firing various mud materials. The glaze layer is generally thick and stress is generated, and the quality is heavy, which easily leads to defects such as cracks and chipping on the glazed surface of the product. Not smooth enough, and the mud is prone to pollution in the production process, high cost and energy consumption, the quality of the product is not stable enough, the gloss of the glaze is not enough, and the color is not rich and stable enough. Fades easily in sunlight. A...
