Problems solved by technology

In order to meet people's demand for whiteness, there are three traditional methods to increase the whiteness of ceramic tiles. One method is to introduce zirconium silicate into the raw material formula of ceramic tiles to improve the whiteness of ceramic tiles, so as to obtain an ultra-white tile. However, zirconium silicate is a chemical raw material with radioactive substances. The ultra-white bricks prepared by using zirconium silicate will bring a certain degree of harm to human health and pollute the environment; another method is to Glaze the brick surface to increase the whiteness of ceramic tiles, but the wear resistance of glazed tiles is relatively poor. Once the glaze is worn, the brick surface will absorb dirt and affect the appearance; another method is to use a large amount of ceramic tiles in the formula Ceramic tiles made of magnesium. The MgO content in this ceramic tile is greater than 8%. Although the whiteness of this ceramic tile has reached the highest level, due to the high MgO content, it directly affects the brightness of the tile surface of the ceramic tile, and is antifouling. poor performance

preparation example Construction

[0037] Such as figure 1 Shown, the preparation method of the polished tile of an embodiment, comprises the steps:

[0038] Step S110: weighing raw materials, adding water and ball milling to obtain slurry. Among them, the mass percentage of raw materials is as follows: feldspar 20%~30%, high temperature sand 10%~28%, high white clay 15%~30%, quartz sand 0~12%, aluminum hydroxide 5%~20%, calcined Talc powder 3%~25%, sodium tripolyphosphate 0.5%~0.8% and methyl cellulose 0.05%~0.2%. The fineness of the slurry is 0.5% to 1.2% on a 250-mesh sieve. The mass percentage of water in the slurry is 32% to 34%.

[0039] By adding water and ball milling, the slurry has a certain flow rate and is more uniform. The fineness of ball milling is 0.5%~1.2% of 250 mesh sieve, which can make the whiteness of polished tiles more uniform and the texture more delicate. Specifically, the ball milling time is 12 hours to 18 hours.

[0040] Step S120: Sieving the slurry and removing iron, and the...

Embodiment 1

[0059] The preparation of the polished brick of the present embodiment is as follows:

[0060] (1) Weigh each raw material according to the mass percentage in Table 1, send it into a ball mill, and add water to ball mill for 12 hours to obtain a slurry. Wherein, the mass percent content of water in the slurry is 32%, and the ball milling fineness is 0.5% over a 250-mesh sieve.

[0061] (2) Pass the slurry in step (1) through an 8-mesh sieve and put it into the slurry tank, then use an automatic iron remover to remove iron, then pass through a 60-mesh sieve, use the automatic iron remover to remove iron again, and then pass through 80-mesh sieve, and then aged at room temperature for 12 hours.

[0062] (3) Use an automatic iron remover to remove iron from the stale treated slurry in step (2), pass it through a 120-mesh sieve, and then use a spray tower to spray and granulate to obtain a billet, wherein the mass percentage of water in the billet is 6.5 %, the particle gradatio...

Embodiment 2

[0068] The preparation of the polished brick of the present embodiment is as follows:

[0069] (1) Weigh each raw material according to the mass percentage in Table 1, send it into a ball mill, and add water to ball mill for 13 hours to obtain a slurry. Wherein, the mass percent content of water in the slurry is 34%, and the ball milling fineness is 0.5% over a 250-mesh sieve.

[0070] (2) Pass the slurry in step (1) through a 10-mesh sieve and put it into the slurry tank, then use an automatic iron remover to remove iron, then pass through an 80-mesh sieve, use the automatic iron remover to remove iron again, and then pass through 100-mesh sieve, and then aged at room temperature for 24 hours.

[0071] (3) Use an automatic iron remover to remove iron from the stale treated slurry in step (2), pass it through a 100-mesh sieve, and then use a spray tower to spray and granulate to obtain a billet, wherein the mass percentage of water in the billet is 7 %, the particle gradatio...

Abstract

The invention discloses a polished tile. The polished tile is obtained by firing a blank prepared from the following raw materials in percentage by mass: 20-30 percent of feldspar, 10-28 percent of high-temperature sand, 15-30 percent of high white clay, 0-12 percent of quartz sand, 5-20 percent of aluminum hydroxide, 3-25 percent of calcined talcum powder, 0.5-0.8 percent of sodium tripolyphosphate and 0.05-0.2 percent of methylcellulose. The polished tile is environment-friendly, high in whiteness and good in performance. Furthermore, the invention also provides a preparation method and the application of the polished tile.

Description

technical field [0001] The invention belongs to the field of ceramic building materials, and in particular relates to a polished brick and its preparation method and application. Background technique [0002] The whiteness of polished tiles is much higher than that of ordinary ceramic tiles. It is hard and wear-resistant, and its appearance is white and flawless, soft and elegant. It is a high-end tile, and it shows that the higher the whiteness of the tiles, the better the market demand. In order to meet people's demand for whiteness, there are three traditional methods to increase the whiteness of ceramic tiles. One method is to introduce zirconium silicate into the raw material formula of ceramic tiles to improve the whiteness of ceramic tiles, so as to obtain an ultra-white tile. However, zirconium silicate is a chemical raw material with radioactive substances. The ultra-white bricks prepared by using zirconium silicate will bring a certain degree of harm to human healt...
