The starlight glaze ceramic tile comprises a body layer 1, a bottom glaze layer 2, a color development glaze layer 3 and a dry particle glaze layer 4 from bottom to top, and is shown in figure 1.
The transparent bright dry granules used for the dry granule glaze layer comprise 38 parts of potassium feldspar, 12 parts of calcined talc, 10 parts of calcite, 33 parts of quartz, 10 parts of barium carbonate, 10 parts of calcined alumina, 5 parts of air knife soil and 3 parts of zinc oxide in parts by weight. The preparation method of the transparent bright dry granules is the same as that of example 1.
The formulation and preparation method of the ground coat are the same as in example 1.
The formula and preparation method of the colored glaze are the same as those of the example 1.
Example 3
The preparation method of the starlight glaze ceramic tile is the same as that of the example 1.
The starlight glaze ceramic tile comprises a blank layer, a ground glaze layer, a color development glaze layer and a dry grain glaze layer from bottom to top.
The transparent bright dry granules used for the dry granule glaze layer comprise 38 parts of potassium feldspar, 12 parts of calcined talc, 8 parts of calcite, 33 parts of quartz, 12 parts of barium carbonate, 10 parts of calcined alumina, 5 parts of air knife soil and 3 parts of zinc oxide in parts by weight. The preparation method of the transparent bright dry granules is the same as that of example 1.
The formulation and preparation method of the ground coat are the same as in example 1.
The formula and preparation method of the colored glaze are the same as those of the example 1.
The difference between the examples 1, 2 and 3 lies in that the proportions of calcite and barium carbonate in the transparent glossy dry particle formulas are different, the surfaces of the transparent glossy dry particles prepared in the examples 1, 2 and 3 have glossy luster, the light reflection is good, the wear resistance of the transparent glossy dry particles is tested according to the method specified in the No. 7 (determination of the wear resistance of the surface of a glazed brick) of GB/T3810.7-2006 ceramic brick test method, the wear resistance can reach 4 grades (the wear resistance is graded to 1-5 grades, the 5 grades are the highest wear resistance grades), and the stain resistance is good. Wherein, the Mohs hardness of the examples 1 and 3 reaches 6 grades, the Mohs hardness of the example 2 reaches 7 grades, and the polishing solution can bear fine surface polishing without glaze cracking, and has good surface flatness after polishing and no waves and pores.
In the prior art, for ceramic tiles with concave-convex effect on the surface, the surface effect can be roughly divided into matte and bright, and the general preparation method is to directly spray matte dry particles or bright dry particles on the surface of the ceramic tile. However, the matte dry-grain glazed ceramic tile prepared in the way is fine and soft in surface, but easily appears as unclear patterns and dim and hazy colors. The bright dry glazed ceramic tile prepared in the way is clearer in color and pattern, but is easy to appear poor in texture. Both of these are conventional dry-grain tile products on the market today.
The application provides a technology with "starlight" effect, drenches bright light dry grain promptly on the brick face, transparent bright light dry grain protrusion in the brick face after kiln high temperature calcination, and the pit is then formed to the position between the transparent bright light dry grain, and the totality demonstrates unevenness's bright face, and the size of its degree of consistency and concave-convex pit depends on the distribution and the granularity of transparent bright light dry grain, can look actual conditions design and arrange. And then the convex surface is subjected to soft polishing, the part with the convex dry particles presents delicate and soft matte feeling after the soft polishing, the concave pits which are not polished still present a bright state, and the surface of the finally obtained ceramic tile presents a shining starlight effect, is called as a starlight glaze ceramic tile, has aesthetic feeling, is trendy and good in decoration, and can fill the blank of the products in the current market.
In addition, the applicant has found in practice that when using transparent bright dry granules of smaller particle size, the depth of the soft polishing also has an effect on the starlight effect. For example, using the formulation of example 2, the frit was crushed and sieved through a 200 mesh screen to give clear bright dry pellets, and the fired tile was soft-polished. Because the granularity is small, the throwable part of the transparent bright dry particles protruding out of the brick surface is smaller, and at the moment, if the throwing depth is large, the transparent bright dry particles are easy to throw to the pit, the bright light of the pit is polished to be dumb, and the starlight flickering effect of the spot spots can be weakened. If the polishing is shallow, the surface smoothness of the brick surface is not enough, and the texture is easy to appear poor. Therefore, for the transparent bright dry granules with smaller granularity, attention needs to be paid to soft polishing depth, and pits cannot be polished.
Example 4
The preparation method of the starlight glaze ceramic tile is the same as that of the example 2.
The starlight glaze ceramic tile comprises a body layer 1, a bottom glaze layer 2, a color development glaze layer 3 and a dry particle glaze layer 4 from bottom to top, and is shown in figure 1.
The formulation and preparation method of the transparent bright dry particles used in the dry particle glaze layer are the same as those in example 2.
The ground glaze used for the ground glaze layer comprises, by weight, 40 parts of potassium feldspar, 30 parts of albite, 8 parts of air knife soil, 20 parts of alumina powder, 8 parts of quartz, 1 part of wollastonite, 12 parts of zirconium silicate, 0.3 part of methyl cellulose, 0.5 part of sodium tripolyphosphate and 42 parts of water. The preparation method of the ground coat is the same as that of example 2.
The formula and preparation method of the colored glaze are the same as those of the example 2.
Example 5
The preparation method of the starlight glaze ceramic tile is the same as that of the example 2.
The starlight glaze ceramic tile comprises a body layer 1, a bottom glaze layer 2, a color development glaze layer 3 and a dry particle glaze layer 4 from bottom to top, and is shown in figure 1.
The formulation and preparation method of the transparent bright dry particles used in the dry particle glaze layer are the same as those in example 2.
The ground glaze used for the ground glaze layer comprises, by weight, 40 parts of potassium feldspar, 30 parts of albite, 8 parts of air knife soil, 20 parts of alumina powder, 8 parts of quartz, 6 parts of wollastonite, 12 parts of zirconium silicate, 0.3 part of methyl cellulose, 0.5 part of sodium tripolyphosphate and 42 parts of water. The preparation method of the ground coat is the same as that of example 2.
The formula and preparation method of the colored glaze are the same as those of the example 2.
Comparative example 6
The preparation method of the starlight glaze ceramic tile is the same as that of the example 2.
The starlight glaze ceramic tile comprises a body layer 1, a bottom glaze layer 2, a color development glaze layer 3 and a dry particle glaze layer 4 from bottom to top, and is shown in figure 1.
The formulation and preparation method of the transparent bright dry particles used in the dry particle glaze layer are the same as those in example 2.
The ground glaze used for the ground glaze layer comprises, by weight, 40 parts of potassium feldspar, 30 parts of albite, 8 parts of air knife soil, 20 parts of alumina powder, 8 parts of quartz, 12 parts of zirconium silicate, 0.3 part of methyl cellulose, 0.5 part of sodium tripolyphosphate and 42 parts of water. The preparation method of the ground coat is the same as that of example 2.
The formula and preparation method of the colored glaze are the same as those of the example 2.
Examples 2, 4, 5 and comparative example 6 differ in the content of wollastonite in the matte glaze formulation. Wollastonite contains no volatile component, and has relatively small sintering shrinkage and drying shrinkage during reaction, so that the wollastonite is favorable for quick sintering, and the gas separated from a glaze surface is reduced, thereby reducing the formation of glaze bubbles or pinholes. In the embodiments 2 and 4, 1 part of wollastonite and 5 parts of wollastonite are respectively added, so that the obtained ground coat glaze bubbles or pinholes are greatly reduced, and the coloring uniformity and the conformity of subsequent colored glaze are more favorable, so that the pattern definition of the starlight glaze ceramic tile is better, and the product has perfect aesthetic feeling by matching with a shining starlight effect, and particularly when the starlight glaze ceramic tile is designed into a starry sky pattern, the effect is incomparable with the ordinary bright ceramic tile in the market.
Compared with the comparative example 6, wollastonite is not added, the obtained ground coat has the advantages of general glaze effect flatness, more surface micropores, uneven distribution and unfavorable coloring of subsequent colored glaze.
At the same time, although the applicant found that the addition of wollastonite in the formulation resulted in a better effect of the under-glaze, the applicant found in actual research and development that when the wollastonite content is too large, such as 6 parts of wollastonite in example 5, the glaze had an increased number of micropores (increased means compared with examples 2 and 4). It can be seen that the requirements for the content of wollastonite are relatively stringent when it is used.
The application provides a formula and a preparation method of a starlight glaze ceramic tile, the obtained ceramic tile has the advantages that the protruding surface dry particles of the ceramic tile are fine, smooth and soft, the whole ceramic tile has a shining starlight effect, the pattern presented is good in definition, the product has aesthetic feeling, is fresh and decorative, the blank of the products in the existing market can be filled, and the various requirements of consumers are met.
In summary, although the present invention has been described with reference to the preferred embodiments, the above-described preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, therefore, the scope of the present invention shall be determined by the appended claims.
