Problems solved by technology

When used as a floor decoration material, there is a greater requirement for the wear resistance of the glaze, otherwise it will be easily scratched. Although this point is greatly improved compared with the existing glass-ceramic composite board, the existing glaze Wear resistance can not meet the demand
[0004] In this regard, some enterprises are solving this problem by thickening the glaze layer. However, as the glaze layer becomes thicker, it will have a certain impact on the products with a printing layer on the surface of the brick. At the same time, as the glaze layer becomes thicker, the manufacturing cost will also increase. , and because it needs to be polished, some bubbles will be sealed in the thick glaze layer, and these bubbles will appear during the polishing process, which will affect the appearance and antifouling performance of the final product, and this way of thickening the glaze layer is also It can only alleviate the problem of poor wear resistance of glaze

Embodiment 1-10

[0020] With reference to the following table 1, the following table 1 is the formula table (wt%) of the wear-resistant transparent glaze provided by the present embodiment 1-5

[0021] Table 1

[0022]

[0023]

[0024] The above glazes are ball-milled and applied on the surface of conventional ceramic tiles. The ceramic tiles used are well-known bricks. The glaze is ball-milled to form a glaze slurry, and a glaze layer of about 1mm is formed on the surface of the tiles by pouring glaze, and then Put it into the kiln for firing, the firing temperature is 1200-1250°C, and the firing cycle is 2.5 hours. It needs to be explained here that, except for the glaze components, other technological processes mentioned above are the known methods for the production of architectural ceramics, and can be appropriately adjusted in different production lines. The frit used here is a transparent medium-temperature frit produced by common ceramics, and its applicable firing temperature ...

Embodiment 3

[0033] Select embodiment 3 to compare

[0034] In this example, spodumene was replaced by albite, and the results showed that the wear resistance of the glaze layer of the product was greatly improved, but the quality of the glaze layer was poor, with many pinhole defects, not stain resistant, and The flatness is poor.

Embodiment 6-8

[0036] In this series of examples, the rest of the components are the same as those in Example 4, except that the frit used is made by melting the raw materials of the following components at 1450-1550°C. The formula components are: 20-30% potassium feldspar, 3-6% wollastonite, 4-8% raw talc, 5-8% barium carbonate, 15-20% calcite, 18-22% quartz, 10-14 % alumina, 2-4% zinc oxide, 1-3% potassium carbonate, 1-2% strontium carbonate. specifically:

[0037] Embodiment 6-8 frit component is as follows table 2 (wt %)

[0038] Table 2

[0039]

[0040] Its wear resistance was tested to reach level 5, and the glaze surface is smoother, which can be polished until the thickness of the glaze layer is 0.3mm or less. This is because the frit, as a flux, also needs to have high wear resistance, so a relatively large amount of alumina is used in this component, and rare earth carbonate and zinc oxide are used as fluxes to make the frit It has high transparency and wear resistance, and...

Abstract

The invention provides a wear-resistant transparent glaze and a method for preparing a glazed tile by utilizing the same. According to the components of the wear-resistant transparent glaze, spodumene, frit, potash feldspar, calcinedtalc, barium carbonate and zinc oxide are adopted as a fluxing agent, and the Si / Al ratio is adopted by utilizing wollastonite and kaolin. Meanwhile, the wear-resistant performance of the glaze is improved by adopting white corundum and zirconium oxide as a wear-resistant agent. The weight percentage of zirconia relative to the total weight of the raw materials of the wear-resistant transparent glaze is smaller than or equal to 0.2%. The above wear-resistant transparent glaze is applied onto the surface of a green body, and then the green body is polished after being sintered in a furnace to obtain a glazed tile product. Compared with the prior art, the wear-resistant transparent glaze is excellent in wear resistance, and can be used for preparing ceramic tiles with thin glaze layers. The decorative properties and the anti-pollution characteristics of obtained products are greatly improved. Meanwhile, the manufacturing cost of products is lower.

Description

technical field [0001] The invention relates to the technical field of architectural ceramics, in particular to a wear-resistant transparent glaze and a method for preparing glazed tiles using the same. Background technique [0002] Polished glazed brick is a high-grade building decoration material, which refers to the glaze layer on the surface of the brick, which can be polished to become a product with a glossy or matte effect. Some products use transparent glaze, which has a glaze under the glaze layer Texture, texture can be realized by various known decorative means, such as the texture formed by cloth, the texture formed by printing and so on. [0003] But because the wear resistance of glaze is a big problem that plagues the industry at present. When used as a floor decoration material, there is a greater requirement for the wear resistance of the glaze, otherwise it will be easily scratched. Although this point is greatly improved compared with the existing glass-c...
