Embodiment 1

[0019] 1. The composition raw materials of ceramic polished tiles in this embodiment

[0020] Magnesia clay 15%

[0021] Quartz 23%

[0022] Kaolin 11%

[0023] Pyrophyllite 14%

[0024] Black Talc 20%

[0025] Wollastonite 12%

[0026] Lithium feldspar 5%

[0027] In addition, add water reducing agent 0.5%

[0028] 2. The manufacturing method of the ceramic polished tile

[0029] 1) Add the above-mentioned composition raw materials into a ball mill, then add water with a total weight of 50% of the above-mentioned raw materials, and ball mill for 8 hours to become mud;

[0030] 2) Spray drying the mud into 5-8% powder, and then press the powder into shape;

[0031] 3) The dried and pressed powder is put into the kiln for firing. The firing temperature range is 1180-1210°C, and the firing time is 68 minutes. After the product leaves the kiln and is cooled, it is polished to become a ceramic polished tile product.

Embodiment 2

[0033] 1. The composition raw materials of ceramic polished tiles in this embodiment

[0034] Magnesia clay 23%

[0035] Quartz 24%

[0036] Kaolin 19%

[0037] Black Talc 18%

[0038] Wollastonite 6%

[0039] Calcite 3%

[0040] Nepheline 7%

[0041] In addition, add water reducing agent 0.5%

[0042] 2. The manufacturing method of the ceramic polished tile

[0043] The difference from Example 1 is that the ball milling time in step 1) is 6 hours. In step 2), the mud is spray-dried to 6-7% powder; in step 3), the range of firing temperature is 1180-1230° C., and the firing time is 65 minutes.

Embodiment 3

[0045] 1. The composition raw materials of ceramic polished tiles in this embodiment

[0049] Black Talc 18%

[0050] Wollastonite 4%

[0051] Dolomite 4%

[0052] Albite 5%

[0053] In addition, add water reducing agent 0.5%

[0054] 2. The manufacturing method of the ceramic polished tile

[0055] The difference from Example 1 is that the ball milling time in step 1) is 10 hours. In step 2), the mud is spray-dried to 6-6.5% powder; in step 3), the range of firing temperature is 1195-1250° C., and the firing time is 115 minutes.

Abstract

The invention discloses a ceramic polished tile, which uses magnesian clay as a main plastic raw material, and mainly uses a SiO2-MgO-CaO-Al2O3 quaternary phase as a formulation system, wherein the SiO2 is between 65 and 85 percent, the MgO is between 5 and 20 percent, the CaO is between 3 and 15 percent, the Al2O3 is between 3 and 15 percent, KNa2O is between 0 and 3 percent, and Fe2O3 and TiO2 are between 0 and 2 percent. The invention also discloses a method for producing the ceramic polished tile. The ceramic polished tile uses the magnesian clay as the plastic raw material so that the source of the raw material is broadened,; and with the addition of talc and quartz, the ceramic polished tile has the characteristics of high brightness, high strength, high hardness, good wear resistance and the like, and has the advantages of wide range of firing temperature, small shrinkage, low product proportion, reduced production cost, low price and high quality, improved product competitive power, and great promoting function for the development of the ceramic polished tile industry.

Description

technical field [0001] The invention relates to the technical field of architectural ceramics, in particular to a ceramic polished tile and a manufacturing method thereof. Background technique [0002] At present, the building ceramics industry generally uses clay that does not contain (or contains less) magnesium and calcium as the main plastic raw material to manufacture ceramic polished tiles. This is because in the existing clay-feldspar system, if magnesium and calcium clay are used As a plastic raw material, the firing temperature range of ceramic polished tiles will be very narrow, and the surface of polished tiles is prone to defects such as deformation, pores or caves, which seriously affects the quality of ceramic polished tiles. Therefore, so far all ceramic polished tiles do not use magnesium and calcareous clay as plastic raw materials, but use non-magnesium and calcareous clays such as black mud, mixed mud, kaolin as the main plastic raw materials. Due to a la...
