Baking-free ceramic prepared by using industrial wastes and preparation method thereof

Abstract

The invention provides a baking-free ceramic prepared by using industrial wastes. The ceramic is characterized in that the ceramic is prepared by the following components in parts by weight: 20-30 parts of magnesium oxide, 15-25 parts of magnesite slags, 12-20 parts of magnesium chloride, 10-20 parts of coal ash, 10-16 parts of diatomite, 6-12 parts of flue gas desulfurization gypsum, 4-8 parts of plant fiber, 3-6 parts of silica sol, and 15-25 parts of water. Magnesite slags, coal ash, flue gas desulfurization gypsum and other industrial wastes are selected, synergistic effect between different solid wastes is fully performed, the baking-free ceramic material obtained by production meets the national standard, comprehensive utilization of industrial solid wastes is realized, pollution of environment due to solid waste discharge is reduced, and economic benefits are improved; and unique raw materials are prepared scientifically, the production process is simple, the production cost is low, and the obtained baking-free ceramic product does not have micro-area cracking and bending phenomenon.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a ceramic product and a preparation method thereof, in particular to an unfired ceramic prepared from industrial waste and a preparation method thereof. Background technique [0002] Ceramic products that people are familiar with generally need high-temperature sintering in the production process. The production process is complicated and consumes a certain amount of energy. Therefore, its production cost is relatively high, and it pollutes the environment. Traditional preparation methods not only have cumbersome procedures, but also consume a lot of energy and pollute the environment, resulting in increased costs and high investment. Although the sintering temperature varies slightly depending on the raw material, the sintering process usually requires a high temperature of 1000-2000°C. Ceramic products made by traditional sintering process are not only costly but also...

Problems solved by technology

If a large amount of fly ash is not treated, it will generate dust and pollute the atmosphere; if it is discharged into the water system, it will cause river silting, and the toxic chemicals in it will also cause harm to humans and organisms
