Description
Technical Field
The invention belongs to the field of ceramic tile glaze, and particularly relates to a ceramic tile overglaze with high whiteness and a preparation method thereof.
Background
The texture of high-quality stone in the market is superior to that of glazed tiles at present, wherein one important item is the whiteness of the ground color, and the whiteness of the high-quality white stone can reach 75 to 85 degrees or even higher. The whiteness which can be achieved by the current ceramic tile production process in the building material industry is only 64 to 67 degrees. Especially, the requirements of the marble-imitated ceramic tile on the whiteness of the glaze surface are higher and higher. The ceramic product can obtain the texture which is closer to the stone and even obtain the artistic expression effect which is superior to the stone. The improvement of the whiteness of the glaze is imperative, and in the existing glaze formula system, the whiteness of the glaze is difficult to be improved to more than 80 ℃ only by adding zirconium silicate into the glaze, so that an ideal high-whiteness ceramic tile glaze does not appear on the market, and therefore, the industry needs to develop a glaze with the whiteness superior to the glaze effect of the whiteness of the existing product so as to meet the design requirement.
Disclosure of Invention
The invention aims to provide a ceramic tile overglaze with high whiteness and a preparation method thereof, aiming at the defects of the prior art.
The technical scheme adopted by the invention is as follows: the ceramic tile overglaze with high whiteness comprises the following raw materials in parts by weight:
specifically, the proportion of the glaze powder and the zirconium silicate is adjusted to achieve a more optimized whitening effect, wherein the zirconium silicate is widely used as a traditional whitening raw material, however, the whitening effect is also influenced by the addition amount of the zirconium silicate according to different ceramic tile glaze raw material components, and the whitening effect in the ceramic tile glaze is optimized by adjusting the addition amount of the zirconium silicate, namely, when the addition amount of the zirconium silicate is too small, the whitening effect is reduced, or the addition amount is too large, the whitening effect is not obviously improved, and the waste of raw materials and the waste of cost are caused. In addition, the addition and the proportion of the sodium tripolyphosphate and the carboxymethyl cellulose effectively improve the post-processing performance of the ceramic tile overglaze.
As a further improvement of the scheme, the overglaze powder comprises the following raw material components in parts by weight:
as a further improvement of the scheme, the titanium titanite is prepared by performing wet ball milling mixing on nano anatase titanium dioxide, high-purity quartz powder and calcite according to the weight ratio of 44.7:32.3:24.5, drying, and then keeping the temperature at 1260 ℃ for 50min at the temperature rise speed of 5 ℃/min.
In particular, the present invention utilizes anatase-type nano titanium dioxide (TiO)2) Calcite (CaCO)3) And the titanic sphene with stable high-temperature performance and good opacifying effect is synthesized with quartz, and then is added into glaze as an opacifying agent, and the whiteness of overglaze is improved by utilizing the characteristic of high refractive index of the titanic sphene. Titanium sphene has good high-temperature stability as an opacifier and can avoid Ti4+Formation of Ti at high temperature3+While the hair was creamy yellow. In the invention, the expansion coefficient of the titanium sphene is larger than that of the surface glaze, and in order to prevent the addition of the titanium sphene from causing great influence on the expansion coefficient of the surface glaze and the adaptability of the surface glaze and the blank, the invention further limits the maximum dosage of the titanium sphene, and the addition amount of the titanium sphene does not exceed 23 percent of the total weight of the surface glaze powder.
As a further improvement of the scheme, the potassium-sodalite powder is formed by mixing potassium feldspar and albite in a weight ratio of 1: 1-1.05. Specifically, the proportion of the potassium feldspar and the albite in the potassium-sodalite powder can further influence the whiteness of the overglaze powder, and the potassium-sodalite powder has higher whiteness by optimizing the proportion and the durability of the whiteness can be ensured in the subsequent processing process.
As a further improvement of the scheme, the mesh number of the overglaze powder is 200 meshes, and the screen residue is less than or equal to 15 percent.
As a further improvement of the scheme, the quartz powder is high-purity quartz powder with the purity of 98-99%, and the alumina is α -alumina.
Specifically, the aluminum oxide has a remarkable effect on whitening the overglaze powder, but the higher the content is, and when the content of the aluminum oxide is too high, the overglaze powder is easy to cause quality problems such as pinholes, foaming and the like in the subsequent processing process.
As a further improvement of the scheme, the zirconium content in the zirconium silicate is not more than 25 percent of the total weight of the overglaze raw material. Specifically, in the prior art, the whiteness of the overglaze is improved by improving the zirconium content in the formula, but the whitening effect of the zirconium content of the zirconium silicate is limited, when the addition amount of the zirconium silicate exceeds 10% of the weight of the overglaze, the whitening effect is gradually deteriorated along with the increase of the addition amount of the zirconium silicate, and when the addition amount of the zirconium silicate is more than 25% of the total weight of the overglaze raw material, the whitening effect is not obviously improved, so that the waste of raw materials and the cost waste are caused, and the problem of post-processing quality and radioactivity exceed the standard easily occur. The high content of zirconium silicate limited by the invention ensures the comprehensive performance of the overglaze and simultaneously has obvious whitening effect. On the other hand, the zirconium silicate with small expansion coefficient is added into the overglaze to counteract the influence of the addition of titanium sphene on the expansion coefficient of the overglaze, and the overglaze is compositely whitened by two opacifiers with different refractive indexes, so that the overglaze has whiteness of more than 82 degrees.
As a further improvement of the above, the carboxymethyl cellulose is a highly viscous methyl group having a viscosity of more than 300 mpa.s.
A method for preparing a ceramic tile overglaze with high whiteness as described above, which comprises the following processes: the glaze powder is prepared by uniformly mixing the raw material components in parts by weight, weighing the glaze powder, zirconium silicate, sodium tripolyphosphate, carboxymethyl cellulose and water in parts by weight, putting the weighed glaze powder, the zirconium silicate, the sodium tripolyphosphate, the carboxymethyl cellulose and the water into a mixing ball mill for ball milling, wherein the ball milling time is 5-6 hours, and the ball milling fineness is controlled within the range of 0.2-0.6% of the rest after the glaze powder is sieved by a 325-mesh sieve.
The invention has the beneficial effects that:
according to the invention, through adjusting the raw material components and the proportion of the overglaze, the addition amounts of titanium sphene and zirconium silicate in the overglaze powder are particularly optimized, so that the overglaze of the ceramic tile has high whiteness and good post-processing performance, and the apparent quality problems of pinholes, foaming, deformation and the like after the overglaze of the ceramic tile is applied are avoided.
The proportion of calcite and titanium titanite contained in the glaze facing powder is adjusted so as to effectively prevent the synthesized titanium titanite from being decomposed at high temperature to generate Ti3+The problem of yellow glaze is caused, after the zirconium silicate is added into the overglaze, the titanium sphene and the zirconium silicate opal whiten the overglaze, because the refractive indexes of the titanium sphene and the zirconium silicate are different, the composite whitening effect of the titanium sphene and the zirconium silicate is better than the whitening effect of a single opacifier, the whiteness of the fired overglaze can reach more than 82 degrees, and compared with the fired effect of the overglaze with the added zirconium silicate alone, the overglaze has better glossiness, the effect of the overglaze is closer to the color of high-quality white stone, and the radioactivity detection meets the national standard requirements.
