Description

Technical Field

[0001] The invention belongs to the technical field of ceramic tiles, and in particular relates to a light-sensitive ceramic tile with combined dry particles and dazzling diamond effect and a preparation method thereof. Background Art

[0002] With the instability of the international situation in recent years, which has affected the slow economic growth, the purchasing power of the consumer group has also tended to decline. All walks of life are also facing huge challenges, especially the ceramic industry, which is under tremendous competitive pressure and internal friction and involution are expanding. Modern consumers are more concerned about the actual quality of the products. Moreover, as an important part of decoration, the good quality of ceramics directly affects the effect of decoration.

[0003] At present, bright-faced tiles still occupy the majority of sales, but it has been difficult for related products to have more technological breakthroughs. The existing bright-faced tile processes include polishing glaze, dry-grain polishing, starry sky glaze, diamond glaze, marble and other few processes; the starry sky glaze and diamond glaze processes on the market basically adopt the method of adding dry grains into the polishing glaze, and then glazing on the brick surface and firing and polishing. This method has the problem that some of the added dry grains will penetrate the glaze surface after polishing, resulting in the glaze surface effect easily producing small pinholes, thus affecting the stain resistance. The addition of dry grains into the polishing glaze during production makes it difficult to stir the glaze evenly and the glaze is easy to stratify and precipitate. The dry grains in the glaze return tank during the glazing process are easy to settle in it, affecting the quality of the glazing. Because the glazing process is easy to evenly distribute the brick surface, the corresponding distribution of the dazzling diamond effect is not easy to change flexibly; at the same time, the proportion of dry grains added will affect the performance of the glaze, resulting in the dazzling diamond effect being limited by the technological performance of the glaze; when dry grains are added into the polishing glaze, the high-temperature corrosiveness of the polishing glaze itself will corrode the added dry grains, resulting in an unsatisfactory dazzling diamond effect. Summary of the invention

[0004] The purpose of the present invention is to solve the deficiencies of the prior art. This invention provides a combination of dry particles, and then by studying the dry particle formula and process means, the proportion of each component in the dry particles is adjusted so that the dry particles include transparent glass balls formed in a molten state after firing, and also include unmelted mineral crystals. The high refractive index characteristics of crystal minerals are used to form a three-dimensional light wave body under the reflection of light, thereby forming different visual effects at different angles. The specific process is powder making, pressing blanks, and after the blanks are dried, glaze is applied to the brick surface, inkjet printing is performed by an inkjet machine, and glue is sprayed after inkjet printing. The combined dry particles are applied by a dry particle machine at the glue spraying position, and then the glaze is applied on it, and then the finished product is obtained by firing, polishing and grinding. In this method, the combined dry particles and the glaze are applied separately, which does not affect each other's own performance, and the high temperature corrosiveness of the glaze will also reduce the erosion of the combined dry particles. The ceramic tile of the present invention has a good crystal feel and transparency, and at the same time has a dazzling diamond effect.

[0005] Based on this, the first aspect of the present invention provides a combined dry particle, including ceramic dry particles and zircon sand dry particles; the raw materials for preparing the above-mentioned ceramic dry particles include, by weight: 2-7 parts of albite, 1-4 parts of dolomite, 15-21 parts of calcite, 9-13 parts of potassium carbonate, 5-10 parts of aluminum oxide, 45-55 parts of quartz powder, 0.5-1.5 parts of barium carbonate, and 6-10 parts of zinc oxide; the above-mentioned zircon sand dry particles are obtained by crushing zircon; the mass ratio of the above-mentioned ceramic dry particles to the above-mentioned zircon sand dry particles is (5-9): (1-5).

[0006] The present invention utilizes the characteristics of zircon's high melting point (2190°C-2420°C) and high refractive index (1.93-2.01) of the original ore, and uses it as a component of the combined dry particles, which can present a bright sparkle effect / dazzling diamond effect after being fired at 1200°C-1220°C in the tile glaze. However, in general, the glaze layer formed by the surface glaze needs a certain degree of transparency to better show the printing layer below, so the composition of the glaze needs to form more glass phases, that is, the mass percentage (content) of sodium oxide will be greatly increased to form a glass phase, and the mass percentage of potassium oxide will be reduced, but the above operation is bound to increase the high-temperature corrosiveness of the glaze, and then will corrode the surface of the above-mentioned zircon sand dry particles, affecting its refractive index and ultimately affecting its visible sparkle (i.e., bright sparkle effect / dazzling diamond effect) presentation.

[0007] On this basis, the present invention proposes to use the combined dry particles obtained by mixing the above-mentioned ceramic dry particles with the above-mentioned zirconium sand dry particles in a specific composition, which can well solve the above-mentioned technical problems. Specifically, the present invention adopts a relatively low mass percentage of sodium oxide (0.2%-0.9%) and a relatively high mass percentage of potassium oxide (7.1%-10.4%) in the ceramic dry particles to reduce the high-temperature corrosiveness of the glaze, and simultaneously adopts a relatively high mass percentage of calcium oxide (9.7%-13.6%), a relatively high mass percentage of zinc oxide (6.8%-11.6%) and a relatively low mass percentage of aluminum oxide (7.1%-13.6%). The calcium oxide glaze has the characteristics of low viscosity at high temperature and high viscosity at low temperature. The high viscosity at low temperature can prevent the erosion of the zircon sand dry particles by the polishing glaze, and the high viscosity itself also has less erosion on the zircon sand dry particles. In the high temperature section of 1200°C-1220°C, the viscosity is low and it is easy to flow, and can be quickly spread on the surface of the zircon sand dry particles. The high temperature section is then the temperature of the rapid cooling section, and the calcium oxide glaze is formed after extreme cooling. The calcium oxide glaze has a strong glass texture and transparency, and can be covered on the surface of the zircon sand dry particles to better reflect the flash of the zircon sand dry particles. When converted into raw material selection, the present invention uses 45-55 parts of quartz powder and 5-10 parts of aluminum oxide as ridge materials to form a skeleton; 2-7 parts of albite are used to introduce aluminum oxide and silicon dioxide, and sodium oxide is introduced at the same time to reduce the surface tension of the glaze and control its high-temperature corrosiveness; 1-4 parts of dolomite are used to introduce magnesium oxide and calcium oxide, which are used to reduce the firing temperature and increase transparency while promoting the dissolution of quartz powder and the formation of mullite; 15-21 parts of calcite are used to introduce calcium oxide, the role of calcium oxide is to form glass with silicon dioxide, and calcium oxide can also improve the elasticity, hardness and glossiness of the glaze, and increase the high-temperature fluidity of the glaze; 9-13 parts of potassium carbonate are used to introduce potassium dioxide to play a role of flux; 0.5-1.5 parts of barium carbonate are used to introduce barium oxide to improve the hardness, wear resistance and chemical corrosion resistance of the glaze; 6-10 parts of zinc oxide (99 zinc oxide can be selected) are used to play a role of flux, reduce the expansion coefficient of the glaze, improve the thermal stability of the product, and at the same time increase the gloss of the glaze surface and improve the elasticity of the glaze.

[0008] During the firing process of the final ceramic tile, the ceramic dry particles will form a melt that covers the surface of the zircon sand dry particles, and at the same time adhere to the glaze layer, the printing layer and the polishing layer.

[0009] In some preferred implementations, the particle size distribution of the above zircon sand dry particles is: 70 mesh-140 mesh ≥ 75%, 140 mesh-200 mesh ≤ 23%, below 200 mesh ≤ 1.8%, above 70 mesh ≤ 0.2%. If the particle size is too large, it is easy to affect the glaze surface, and if the particle size is too small, it cannot present a dazzling diamond effect. Specifically, if the particle size is coarser than 70 mesh, the particles are easy to bulge the glaze surface, and when the particles stand up, gaps are easily formed at the bottom, affecting the quality of the glaze surface; if the particles are finer than 140 mesh, the particles are too fine and lack visual perception, so the number of particles in this part should not be too much, and can be used to fill the gaps between particles.

[0010] It should be noted that all “%” in the present invention refer to “mass percentage”, which is equivalent to “mass fraction” and “mass percentage content”.

[0011] In some preferred implementations, the particle size distribution of the ceramic dry particles is the same as that of the zircon sand dry particles. Maintaining the same particle size distribution makes it easier to evenly mix the ceramic dry particles with the zircon sand dry particles.

[0012] Among the raw materials of the above-mentioned ceramic dry particles, the mass percentage of K2O in the chemical composition of albite is greater than 10.0%; the mass percentage of CaO in the chemical composition of calcite is 50%-58%, the mass fraction of SiO2 in the chemical composition of quartz powder is greater than 98%, the chemical composition of dolomite is MgO: 19%-24%, CaO: 30%-35%, and the mass fraction of BaO in barium carbonate is greater than 70%. The main chemical components of the ceramic dry particles include, by mass percentage: SiO2: 54.6%-63.8%, Al2O3: 7.1%-13.6%, MgO: 0.5%-1.3%, CaO: 9.7%-13.6%, Na2O: 0.2%-0.9%, K2O: 7.1%-10.4%, BaO: 0.4%-1.4%, ZnO: 6.8%-11.6%, the mass percentage of Fe2O3+TiO2 is less than 0.2%, and the remainder is loss on ignition and impurities.

Since the combined dry particles are to be between the two glaze layers of the surface glaze and the polishing glaze, it is necessary to minimize the volatile components to avoid forming pinholes on the glaze surface. Therefore, in the preparation process of the above-mentioned combined dry particles, the raw materials are fully chemically reacted in a high-temperature molten state to reduce the generation of volatile components by chemical reactions again during the later firing process of the ceramic tiles.

[0015] The melting temperature is 1530°C-1570°C; and the drying is performed until the moisture content is less than 0.05%.

[0095] The ceramic tiles of Examples 1-6 and Comparative Examples 1-4 were tested. The test methods for wear resistance and antifouling performance were carried out according to the provisions of the ceramic tile testing standard GB / T4100-2015. The antifouling performance and glossiness were tested by sampling the area where the combined dry particles were relatively concentrated. The convex and concave feel of the glaze surface was determined by subjective touch of the area where the combined dry particles were concentrated and the contrast of the area with no or few combined dry particles. The transparency and dazzling diamond texture of the glaze surface were determined by subjective observation of the transparency of the glaze surface and the presentation of the dazzling diamond texture of the particles. The results are shown in Table 7.

[0096] Table 7

[0097]

[0098]

[0099] From the results of the examples, it can be seen that from Examples 1 to 4, it can be seen that the glaze of the ceramic tile can well present star-shaped bright spots at the position where the combined dry particles are designed. The touch of the dry particle gathering area and the position without or less combined dry particles are smooth and delicate. In Example 2, the ratio of ceramic dry particles to zircon sand dry particles is 9:1. The zircon sand dry particles are relatively few, and the brick glaze has a dazzling diamond effect, but the particle effect appears sparse. In Comparative Example 1, the aluminum oxide content is low, the potassium oxide content is high, and the firing temperature of the ceramic dry particles is low. During the firing process, the ceramic dry particles are easily eroded after high-temperature melting, which reduces the dazzling diamond effect on the brick surface. In Comparative Example 2, the aluminum oxide content is high, the potassium oxide content is low, and the temperature of the ceramic dry particles is high. Small protrusions are likely to appear at the position where the ceramic tile is designed with combined dry particles, and it is easy to be uneven during polishing. In Comparative Example 3, the ratio of zircon sand is reduced, and the ceramic tile glaze presents too few star-shaped bright spots at the position where the combined dry particles are designed, which is not obvious (as shown in the photo). Figure 5 As shown in the figure). In comparative example 4, the ratio of zircon sand was increased. In the position where the combined dry particles were designed, some zircon sand dry particles were stacked on the tile glaze surface. There were cavitations between the stacked particles, which affected the glaze effect of the tile. After some cavitations were polished and worn, the anti-fouling property and glossiness decreased (as shown in the photo). Figure 6As shown). Example 5, the glaze composition reduces the content of sodium feldspar. Sodium feldspar mainly introduces sodium oxide. The reduction of sodium oxide content will increase the firing temperature of the glaze, and the glass phase in the glaze is insufficient, and the glaze surface is not transparent. At the same time, it is easy to be not cooked at high temperature, resulting in a decrease in antifouling property. Example 6, the content of sodium feldspar is increased. Sodium feldspar mainly introduces sodium oxide. The increase of sodium oxide content increases the glass phase of the glaze, and the glaze surface has a strong sense of transparency, but the increase of glass phase weakens its wear resistance.
