Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ceramic tiles, and specifically discloses a wax dry granular glaze, a wax ceramic tile with a 3D stereoscopic effect, and a preparation method thereof. BACKGROUND

[0002] With the progress and continuous development of society, people's quality and aesthetic requirements for ceramic tiles are also gradually developing and changing. The rapid development of matte tiles shows that people's demand for matte tiles is increasing. Compared with bright tiles, matte tiles have low gloss, small light pollution, soft and non-stinging color, and are relatively easier to maintain, and are increasingly loved by consumers. However, the current matte tile products generally have a gloss of 5-20°, lack of level and stereoscopic effect in visual effect, and the texture and hand feel are relatively rough. There is no matte tile surface with a stereoscopic level effect, and the glaze has a smooth and greasy effect like paraffin wax.

[0003] The existing matte glaze formula mainly uses one or more of calcium oxide, magnesium oxide, barium oxide, and strontium oxide, which are divalent oxides, to precipitate crystals during kiln firing, producing a matte effect. Generally speaking, divalent oxides play a role in fluxing in the glaze formula, reducing the viscosity of the glaze and improving high-temperature fluidity. However, when too much divalent oxide is introduced into the glaze, the high-temperature viscosity decreases, and the glaze surface is prone to defects such as pinholes and pimples.

[0004] Divalent oxides are mainly introduced by divalent carbonate raw stone. At high temperatures, carbonates need to be decomposed first, and then interact with other components. Since the decomposition requires time, and most ceramic factories currently use low-temperature fast firing, when the firing speed is increased and the firing time is shortened, the maximum firing temperature is lowered, and some carbonates may not even have time to react, thus causing the firing range to narrow, and poor control leading to glaze defects such as glaze loss of transparency, glaze pores, increased pimples, and other glaze defects, increasing the difficulty of production.

[0005] Currently, for the glaze surface problem of wax ceramic tiles, patent number CN114956573A discloses a wax glaze, a wax 3D ceramic tile, and a preparation method thereof. The glaze avoids the problem of air holes caused by the presence of organic matter and carbonates in the glaze components by using calcined frits to improve glaze defects. However, the frit usage ratio of this patent is very high, and since frits need to be fired, crushed, and dried, etc., the price of frits is more expensive than that of raw stone, ultimately leading to a relatively high cost of wax glaze, making it difficult to form a stronger competitive advantage in the market, and failing to be widely applied and promoted. Secondly, the glaze of this patent contains a large amount of frit dry particles. To ensure suspension, air knife soil is added. Since the specific gravity of air knife soil is generally much smaller than that of frits (frit specific gravity is 2.0 g / cm 3And above, the air knife soil specific gravity is 1.2~1.5g / cm 3 ), both specific gravity difference is big, and the frit of the glaze is more than 70%, in the continuous production process, the frit is still easy to precipitate and group, it can be seen that the performance quality of the waxiness glaze in the prior art still has larger progress space.

[0006] In view of the existing defects of matte glaze and the production difficulty of matte ceramic tile, the patent develops a waxiness dry particle glaze with fine and smooth glaze surface and low cost. SUMMARY

[0088] A ceramic tile glaze, Comparative Example 1 differs from Example 1 in that the glaze does not contain dry granular fine powder. The glaze is sprayed on the green tile and fired using the same process as Example 1.

[0089] The glaze of Comparative Example 1 has a glossiness of 12° and 3 blemishes.

[0090] Comparative Example 2

[0091] A ceramic tile glaze, Comparative Example 2 differs from Example 1 in that the glaze is obtained by mixing the glaze raw materials of Example 1 with dry granular fine powder raw materials, and then ball milling. The glaze is sprayed on the green tile and fired using the same process as Example 1.

[0092] The glaze of Comparative Example 2 has a glossiness of 23° and 3-6 pinholes.

[0093] Comparative Example 3

[0095] The glaze of Comparative Example 3 has a glossiness of 32°, and the effect is as shown in the figure, the glaze has average transparency. Figure 5

[0096] From the glossiness and glaze effect comparison between Example 1 and Comparative Example 1, it can be verified that the dry granular fine powder of the present application has excellent effect of improving the texture of the ceramic tile glaze. From the comparison of the effects between Example 1 and Comparative Example 2, it is also verified that the key to the excellent improvement effect of the dry granular fine powder on the glaze is not only the special composition obtained from the raw materials, but also the special treatment of mixing the dry granular fine powder with the glaze raw materials after air flow milling and ball milling.

[0097] ​The dry granular powder of the present application is a dry granular powder of strontium and barium-containing frit crushed to 325 mesh or less. Since the organic matter and carbonates in the components have been removed in advance through pre-calcination, the dry granular powder can start melting at a lower temperature during the firing process after being mixed with the glaze, and after melting, it interacts with the glaze at high temperature, which helps the glaze melt at high temperature and form a fine glass phase and crystals with the glaze, thereby improving the softness of the ink of the finished product, improving the texture of the glaze, and having a smooth and delicate wax-like feel. Moreover, by precisely controlling the amount of divalent oxide introduced through the addition of the dry granular powder, the present application cooperates with the glaze to not only solve the fluxing effect and save kiln energy consumption, but also improve the glaze defects caused by unstable firing process, so that the glaze of the finished product maintains the ideal matte effect while effectively eliminating glaze defects.

[0098] The dry granular powder of the present application particularly uses potassium feldspar, sodium feldspar, dolomite, calcite, barium carbonate and strontium carbonate as raw materials. Sodium feldspar provides K2O and Na2O, which plays a role in fluxing. Dolomite and calcite provide CaO and MgO, which can effectively improve the fluidity and high-temperature viscosity of the glaze, adjust the surface tension of the glaze, and provide BaO and SrO when controlled within a certain amount, which can produce a matte effect and increase the tendency to crystallize. See the performance test results of Example 1 and Comparative Example 3 for comparison. The effective effect of adding frit dry granules in the present application is: a, the dry granule melting temperature and firing temperature is low, which can effectively reduce the melting temperature and firing temperature of the glaze, and plays a role in fluxing; b, the dry granule contains strontium and barium, which melts at a lower temperature, can promote the reaction with the raw materials in the glaze, and is more likely to crystallize at high temperature, generating fine crystals and producing a matte and wax-like effect. Therefore, the wax-like glaze of the present application has a lower frit usage ratio, and can also achieve the same performance quality as the high frit usage glaze of the prior art. Not only does it greatly reduce the cost of wax-like glaze, but it also effectively avoids the problem of dry granular powder sedimentation and clumping during continuous production.

[0099] In addition, the present application further studies the effect of adding dry granular powder on the glaze slurry. Since the dry granular powder is in a powder state with a fineness of 325 mesh or less and a specific gravity greater than that of the glaze slurry, it is easy to agglomerate and settle when directly added to the glaze slurry. The present application improves the suspension by introducing ball clay, which has a smaller specific gravity than the dry granular powder and a suitable difference in specific gravity, thereby better solving the problem of dry granular powder agglomeration and sedimentation, and further improving the glaze transparency and smoothness.

The above description of the examples is only used to help understand the method of the present application and its core idea. Meanwhile, for those skilled in the art, according to the idea of the present application, the specific implementation manners and application ranges will be changed, and the above description should not be understood as a limitation on the present application.
