Description
Technical Field
The invention relates to the technical field of ceramic bricks, and particularly discloses a waxy dry grain glaze, a waxy ceramic brick with a 3D stereoscopic effect and a preparation method thereof.
Background
With the advancement and continuous development of society, the quality and aesthetic requirements of ceramic tiles are also gradually developed and changed. The rapid development of the matte bricks shows that people have greater demands on the matte bricks, and compared with the glossy bricks, the matte bricks have the advantages of low glossiness, small light pollution, soft and non-dazzling color, relatively easier management and increasing preference of consumers. However, the glossiness of the existing matte ceramic tile products is generally 5-20 degrees, layering and three-dimensional sense are lacked in visual effect, the texture and the hand feeling are rough, no matte ceramic tile surface has three-dimensional layering effect, and meanwhile, the glazed hand feeling has paraffin-like smooth and greasy effect.
The matte glaze formula in the prior art mainly utilizes one or more of divalent oxides such as calcium oxide, magnesium oxide, barium oxide, strontium oxide and the like to precipitate crystals in the kiln sintering process, so as to generate a matte effect, and in general, the divalent oxides play a role in assisting fusion in the glaze formula, so that the viscosity of the glaze can be reduced, and the high-temperature fluidity can be improved. However, when excessive divalent oxide is introduced into the glaze, the high-temperature viscosity becomes low, and the glaze is easy to generate defects such as pinholes, miliaria and the like.
The divalent oxide is mainly introduced from the raw stone material of divalent carbonate, and the carbonate needs to be heated to decompose at high temperature and then interact with other components in the components. Because the time is needed for thermal decomposition, the low-temperature quick firing mode is generally adopted in the ceramic factory at present, when the kiln firing speed is fast, the firing time is shortened, and after the highest firing temperature is low, part of carbonate is even less than reacted, so that the firing range is easily narrowed, the bad control can lead to devitrification of the glaze, increase of glaze pores and prickly heat or other glaze defects, and the production difficulty is increased.
Currently, for the problem of the glaze surface of waxy ceramic tile glaze, patent number CN114956573A discloses a waxy glaze, waxy 3D ceramic tile and a preparation method thereof, wherein the glaze material adopts calcined frit to avoid the problem of air holes caused by organic matters and carbonate in the glaze material component so as to improve the defect of the glaze surface. However, the amount of the frit in the patent is very large compared with that of the wax glaze, and because the frit needs related procedures such as firing, crushing, drying and the like, the frit is more expensive than the raw stone, and finally the cost of the wax glaze is relatively high, so that stronger competitiveness is difficult to form in the market, and the frit cannot be widely popularized and applied. Secondly, the glaze adds a large amount of dry particles of the frit, air knife soil is added for ensuring suspension property, and the specific gravity of the air knife soil is generally far smaller than that of the frit (the ratio of the frit is 2.0 g/cm) 3 And the specific gravity of the air knife soil is 1.2-1.5 g/cm 3 ) The specific gravity difference of the two is larger, the frit of the glaze accounts for more than 70 percent, and in the continuous production process, the frit is still easy to precipitate and agglomerate, so that the performance and quality of the waxy glaze in the prior art have a larger progress space.
Aiming at the defects of the glaze surface of the existing matte glaze and the production difficulty of the matte ceramic tile, the patent develops the wax dry grain glaze with fine and smooth glaze surface and lower cost.

From comparison of the glossiness of example 1 and comparative example 1, it was confirmed that the dry grain fine powder of the present invention has an excellent effect of improving the glazed texture of ceramic tiles. From the comparison of the presentation effects between the example 1 and the comparative example 2, it was also verified that the dry grain fine powder of the present invention plays an excellent role in improving the glaze, and the key point thereof is not only the special ingredients obtained by the raw materials, but also the special feature that the dry grain fine powder and the glaze slurry raw materials are respectively treated by air flow grinding and ball grinding and then mixed.
The dry grain fine powder is the dry grain fine powder which is crushed into less than 325 meshes by the frit containing strontium and barium, and organic matters and carbonate in the components are discharged in advance after being calcined in advance, so that after the dry grain fine powder is mixed with the glaze, the dry grain fine powder can be melted at a lower temperature in the sintering process, and the melted dry grain fine powder interacts with the glaze at a high temperature to be beneficial to the melting of the glaze at the high temperature and the formation of fine glass phases and crystals with the glaze, thereby improving the soft feel of the ink of a finished brick, improving the glaze texture, enabling the glaze to be transparent and having silky fine wax texture. In addition, the invention precisely controls the introduction amount of the divalent oxide by adding the dry grain fine powder and is matched with the glaze, thereby not only solving the fluxing action and saving the energy consumption of a kiln, but also improving the glaze defect caused by unstable sintering process, so that the glaze of the finished product maintains ideal matte effect, and simultaneously, the glaze defect is effectively eliminated.
The dry granule fine powder of the proposal adopts potassium feldspar, albite, dolomite, calcite, barium carbonate, strontium carbonate and the like as raw materials, and the albite provides K 2 O and Na 2 O plays a role in assisting fusion, dolomite and calcite provide CaO and MgO, the fluidity and high-temperature viscosity of the glaze can be effectively improved, the surface tension of the glaze is adjusted, barium carbonate and strontium carbonate provide BaO and SrO, and when the content is controlled to be a certain amount, the effect of no light can be generated, and the crystallization tendency is increased. See in particular example 1 for comparison with the performance test results of comparative example 3. The effective effect of adding frit dry particles in the scheme is as follows: a. the melting temperature and the sintering temperature of the dry particles are low, so that the melting temperature and the sintering temperature of the glaze can be effectively reduced, and the melting is assisted; b. the dry particles contain strontium and barium, and the dry particles are melted at a lower temperature, so that the dry particles can promote the reaction with raw materials of the glaze, the reaction is easier to crystallize at a high temperature, fine crystals are generated, and the matte and waxy effects are produced. Therefore, the usage amount of the frit of the waxy glaze in the scheme is lower, the equivalent performance and quality of the frit glaze with high frit usage amount like the prior art can be achieved, the cost of the waxy glaze is greatly reduced, and the problems of precipitation and agglomeration of dry particle fine powder during continuous production are effectively avoided.
In addition, the invention also makes further study on the influence of the addition of the dry grain fine powder on the glaze slip, and in the mixing process of adding the dry grain fine powder into the glaze slip, because the dry grain fine powder is in a powdery initial state, the fineness is less than 325 meshes, the specific gravity is greater than the specific gravity of the glaze slip, and agglomeration and precipitation are easy to generate when the dry grain fine powder is directly added into the glaze slip. The invention improves suspension property by introducing the ball clay, the ball clay has smaller specific gravity than the dry grain fine powder, and the specific gravity difference between the ball clay and the dry grain fine powder is proper, thereby better solving the agglomeration and precipitation problems of the dry grain fine powder, and further improving the transparent feeling of the glaze surface and the fineness of the glaze surface.
