Abstract
The invention provides a crystal bright glaze, which comprises the following chemical components in percentage by mass: 2.3 to 63.93 percent of SiO 2 7.3 to 10.64 percent of Al 2 O 3 6.13 to 8.27 percent of CaO, 4.2 to 6.2 percent of MgO and 3.3 to 4.9 percent of K 2 O, 3.53-7.96% BaO, 2.69-5.74% SrO and 3.18-7.3% ZnO. The crystal bright glaze has higher surface glossiness and good transparent and texture effects, and can obviously improve the pattern color effect when being applied to ceramic plates.
Description
Technical Field
The invention relates to the technical field of building ceramics, in particular to a crystal glaze, a ceramic plate and a preparation method thereof.
Background
The traditional process of the glazed tile is that the glazed tile is made up by pressing, drying, spraying ground glaze (overglaze), spraying pattern, spraying transparent glaze, sintering, edging and polishing. During firing, the conventional transparent glaze melts part of SiO 2 And Al 2 O 3 And generating a glass phase, filling the glass phase in the gaps of the matrix skeleton, and improving the density and transparency of the glaze layer. Since the pattern texture of the full-polished glazed ceramic plate is an effect which is exhibited after polishing the transparent glaze layer which is covered on the glaze plate and plays a protective role, the higher the content of the glass phase substance of the transparent glaze layer is, the more transparent the transparent glaze layer is, just like transparent glass, and the better the pattern color development effect of the lower layer is.
The traditional transparent glaze is easy to generate bad phenomena such as pinholes, bubbles and the like in the preparation process, and when the transparent glaze is polished, the pinholes, the bubbles and the like are exposed, so that the antifouling performance is not up to standard. In order to solve the defect, the traditional technology is to add a higher proportion of aluminum oxide to the formula to improve the viscosity of the glaze layer, so that bubbles of the glaze layer are sealed and pressed on the polished glaze bottom layer, and finally, better antifouling property is ensured. Although the antifouling property can reach the standard by adopting the technical means, bubbles and pinholes of the antifouling property still exist, and the permeability of the glaze layer is reduced. Meanwhile, due to the existence of alumina with higher mass ratio, the phenomenon of dull luster of the glaze layer caused by high temperature in the firing process can be caused, and the requirement of pursuing more transparent texture on the surface of the ceramic plate is also restricted.

Effect characterization
The ceramic plates prepared in examples 1 to 6 and comparative example 1 were tested for surface stain resistance, abrasion resistance and surface quality by the method of GB/T3810.14, and gloss by the method of gloss meter, and the specific test results are shown in the following table:
table 1 table of performance tests of the products prepared in examples 1 to 6 and comparative example 1
From the data of example 1 and comparative example 1, it can be seen that when strontium carbonate is replaced with sodium carbonate in the raw material, pinholes and pinholes are relatively apparent on the surface of the sheetThe strontium carbonate introduced by the invention can reduce the opacification phenomenon caused by crystallization to a certain extent, is beneficial to forming more glass phase substances, increases transparency and color development effect and improves antifouling performance.
As can be seen from the data in examples 1-3 of the table, the crystal bright overglaze ceramic plate prepared by adopting the technical scheme of the invention has the glossiness of 93-96 degrees, the stain resistance reaching more than 5 levels, excellent wear resistance reaching more than 3 levels, no pinholes,Sub-defects, high surface glossiness, strong permeability, good color development, good quality, etc. As can be seen from the data of example 1 and example 4, when SiO 2 With Al 2 O 3 When the mass percentage ratio of the aluminum oxide is too small, the aluminum oxide content is relatively large in the formula ratio, the aluminum oxide needs to be melted at a higher temperature, and meanwhile, the glossiness value is obviously reduced, and the transparency and the color development effect are general; as can be seen from the data of examples 1 and 5, when SiO 2 With Al 2 O 3 When the mass percentage ratio of (2) is too large, namely the content of alumina is relatively small in the formula ratio, the wear resistance and hardness are relatively reduced; as can be seen from the data of examples 1 and 6, when the sum of the mass percentages of CaO, baO, znO and SrO is too small, the fluxing process is slow, and accordingly the formation process of the glassy phase substance is slow, so that the surface glossiness of the product is low, and the glaze is dull and heavy and the penetration feel is poor.
The above description shows that the ratio of the silicon oxide to the aluminum oxide in the technical scheme provided by the invention is the sum of CaO, baO, znO and SrO in percentage by mass.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
