Problems solved by technology

[0006] However, CN200510020723.9 has the following defects: the raw material selection of the method for producing ceramic tiles is generally used to manufacture various materials of ceramic tiles in the prior art, including kaolin and feldspar, etc., also adding muscovite and sericite, and calcium carbonate and Wollastonite and other minerals, the compatibility of these raw materials is not good during the mixing and sintering process, and there is still phase separation in the molten state, which is not uniform enough, which affects the overall performance of the product

Embodiment 1

[0048]The binder bentonite with a particle size of 0.3mm was calcined at 800°C for 30 minutes, and 6 kg of the calcined bentonite was mixed with 15 kg of clay, 15 kg of kaolin, 10 kg of sodium sodium, 10 kg of potassium feldspar, and 39 kg of quartz Feldspar tailings, 5 kg of lithium feldspar raw material and 100 kg of water are mixed and stirred to make a slurry; the slurry is ground by a 40T ball mill with a diameter of 4 mm high alumina balls to a particle size of 250 mesh sieve 1.5, use the air dryer to dry the mud material into powder; press the dried powder in the mold and then burn it in the kiln at 900°C---1300°C for 40 minutes to obtain a superfine powder with a thickness of 3.5mm. Thin exterior wall bricks, after testing, have a water absorption rate of 0%, a breaking strength of 651N, and a modulus of rupture of 65.9MPa.

Embodiment 2

[0050] The binder bentonite with a particle size of 0.6mm was calcined at 900°C for 50 minutes, and 8 kg of the calcined bentonite was mixed with 12 kg of clay, 12 kg of kaolin, 8 kg of albite, 12 kg of potassium feldspar, and 41 kg of quartz Feldspar tailings, 6 kg of lithium feldspar raw material and 70 kg of water are mixed and stirred to make a slurry; the slurry is ground with a 40T ball mill and high alumina ball stone with a diameter of 8mm to a particle size of 250 mesh sieve 2%, dry the slurry with a spray dryer and dry the slurry into a powder; press the dried powder in a mold and then burn it in a kiln at 1185°C---1200°C for 50 minutes to obtain a thickness of 4.6 mm ultra-thin exterior wall brick, after testing, its water absorption rate is 0.1%, breaking strength: 682N, rupture modulus: 67.5MPa.

Embodiment 3

[0052] The binder bentonite with a particle size of 0.1mm was calcined at 800°C for 20 minutes, and 4 kg of the calcined bentonite was mixed with 18 kg of clay, 18 kg of kaolin, 12 kg of albite, 8 kg of potassium feldspar, and 37 kg of quartz Feldspar tailings, 4 kg of lithium feldspar raw materials and 80 kg of water are mixed and stirred to make a slurry; the slurry is ground in a 40T ball mill with a diameter of 6 mm high alumina balls until the particle size is 250 mesh sieve and the remaining 1.5 , use the air dryer to dry the slurry into powder; press the dried powder in the mold and then burn it in the kiln at 1185°C---1200°C for 45 minutes to obtain an ultra-thin powder with a thickness of 4.0mm. The exterior wall brick, after testing, has a water absorption rate of 0.1%, a breaking strength of 623N, and a modulus of rupture of 63.2MPa.

Abstract

The invention relates to an ultra-thin ceramic external tile and the preparation method. The components and contents of the ceramic external tile are as follows: 12 to 18 parts by weight of clay, 4 to 8 parts by weight of binder, 12 to 18 parts by weight of kaolin, 17 to 22 parts by weight of sodium feldspar and the potassium feldspar respectively, 37 to 41 parts by weight of quartz feldspar tailings and 4 to 6 parts by weight of lithium feldspar. The ultra-thin ceramic external tile prepared by adopting the composition of the present invention is about 3.5mm to 4.6mm thick, reducing the weight from 13kg / m<2> of the conventional products to 6kg / m<2>. The invention has the advantages that the thickness is reduced, however, the strength is highly increased, moreover, the energy is saved, the cost is reduced, the weight of the tile on unit area is greatly reduced, the energy is saved and transportation cost is reduced.

Description

technical field [0001] The invention relates to an ultra-thin ceramic exterior wall brick and a production method thereof. Specifically, the invention relates to an ultra-thin ceramic exterior wall brick prepared by using a mixture of various clays and feldspars and a production method thereof. Background technique [0002] In line with the implementation of mandatory energy-saving standards in the ceramic industry, the use of building exterior wall insulation materials also requires the weight and thickness of ceramic tiles to be lighter and thinner. [0003] The prior art discloses some relevant documents, for example: [0004] CN03222998.4 (Guangdong Keda Electromechanical Co., Ltd.) discloses a forming press for producing ultra-thin large-scale ceramic tiles, which can produce ceramic tiles with a thickness of 3-5 mm, a width of 1 meter, and a length of 3 meters. machinery field. It includes a main frame, a stamping device and a belt conveying material distribution dev...
