Problems solved by technology

These studies have found ways to reuse gold tailings, but all of them are materials with low added value and single function, and the utilization rate of gold tailings is not high
The inventor also used 5-25% gold tailings combined with bamboo charcoal powder to prepare multifunctional ceramsite in the publication number CN101580349, but the process is slightly complicated and the utilization rate of tailings is still low

Abstract

The invention discloses an ecological ceramic tile. Main raw materials of the ecological ceramic tile comprise 70 to 90 percent of gold tailings particles, 5 to 25 percent of bamboo carbon and 5 to 15 percent of purple gold clay. Aqueous solution of sodium silicate, with the weight of 2 to 4 percent of the total weight of the raw materials, is used as a bonder. A preparation method of the ecological ceramic tile comprises the following steps of: 1, placing the main raw materials into a mixer to mix the main raw materials for 5 to 15 minutes, then adding the aqueous solution of sodium silicateto mix for 60 to 120 minutes and carrying out ageing mixture for 10 to 14 hours to obtain a mixture; 2, carrying out pressure forming on the mixture under the pressure of 30 to 80MPa and then naturally drying the obtained product by 12 to 24 hours to obtain a dried formed product; and 3, sintering the dried formed product for 2 to 4 hours at the temperature of 1,000 to 1,250 DEG C to obtain the ecological ceramic tile. The ecological ceramic tile has functions of ammonia adsorption, far infrared emission and the like.

Description

technical field [0001] The invention relates to an ecological ceramic brick and a preparation method thereof, in particular to a ceramic brick used for an interior wall and a production method thereof. Background technique [0002] In today's society, environmental protection has been deeply rooted in the hearts of the people, but the treatment of gold tailings in industry has always troubled people. A large number of tailings not only pollute the atmosphere, but also occupy arable land. Therefore, the reuse of gold tailings is a hot topic of research. Studies have shown that gold tailings can be used as raw materials for glass, to produce glass-ceramics, aerated concrete, hollow bricks, autoclaved bricks, etc. And the development of its new use has also been explored by people. [0003] Regarding the utilization of gold tailings in building materials, the publication number CN 101054308 uses 30-40% gold tailings to prepare breathable bricks, CN101289325 uses 55-75% to prep...
