Description
Technical Field
The invention relates to the technical field of production and manufacturing of ceramic tiles, in particular to crystal flash dry granules, a crystal flash ceramic tile and a preparation method thereof.
Background
With the increasing living standard of people, the requirements for personalized decoration of ceramic tile decorative materials, such as color patterns, texture details, tactile sensation and the like, are higher and higher. Besides being traditional decorative materials, ceramic tiles also need to be personalized artworks. The diamond glittering effect glaze belongs to one of crystalline glazes and shows the effects of starlight glittering and bright dazzling under the irradiation of light.
The common flashing components of the brick surface of the high-temperature (more than or equal to 1180 ℃) porcelain brick flashing under the light comprise mica sheets, bright glaze or low-temperature transparent dry particles and zirconite. Wherein, the mica sheet is used as a flash component, and the flash point generated by the mica sheet has dark black color, so that the decoration effect of the surface pattern of the ceramic tile can be influenced on the products with light color system or bright color system. The mica sheet achieves a flashing effect through the mirror reflection difference of light, can be only applied to matt bricks or semi-polished bricks, and cannot be applied to the surface of a polished product (the glossiness is more than or equal to 75 ℃) with the largest market demand. The gloss glaze or low-temperature transparent dry particles are used as a flash component, so that the glossiness of the fired glaze or low-temperature transparent dry particles is not strong, and the visual gloss contrast is not obvious. The ceramic tile with the glaze flashing effect is not real enough all the time, and the diamond-like flashing effect of crystal grains similar to stone under light cannot be achieved. The zircon is used as a flashing component, and the zircon contains impurities, so that the problems that white bricks are more dirty, the radioactivity of ceramic bricks exceeds the standard and the like are caused. Furthermore, not all zircon sands are suitable as flash dry granules.
In addition, in the manufacture of ceramic tiles, various products have different expression forms of glossiness, such as different gloss effects of dull, matte, satin, high gloss, bright gloss and the like. The existing ceramic tile glaze surface flashing process is more, but some flashing processes are glazing processes, are used for products without light and matt, cannot be subjected to full-polishing processing, and are not suitable for full-polishing products. And a part of flashing dry particle materials are not stable after being fired at high temperature in the glaze, and are easy to react with the glaze, so that the flashing effect is weakened, and the decorative effect is not good.

The invention has the beneficial effects that:
according to the invention, the crystalline flash dry particles are prepared by taking the zircon which is a side mineral invading rock as a raw material, because the zircon crystals are in a square double cone shape, a columnar shape or a plate shape, trigeminal crystal boundaries can be formed among the particles, and through the cooperation of diffuse reflection on the crystalline flash dry particle crystal boundaries and reflection on the trigeminal crystal boundaries, the reflection characteristics are enhanced, the crystalline flash effect at different angles is realized, and thus the flash effect of the ceramic tile is improved. On the other hand, by adding 18-45 parts by weight of boric acid, boron oxide participates in a glass structure formed by silicon dioxide to form a high borosilicate system with a low expansion coefficient when preparing flash dry grains, so that the flash dry grains have a very low expansion coefficient. When the crystal flash dry grains are mixed with the glaze layer material on the surface of the green brick, larger expansion coefficient gradient difference is generated, so that controllable crystal boundaries are generated around the crystal flash dry grains, and when light rays irradiate, reflection and refraction are generated on the interface. In addition, the lithium carbonate with the content of 0.2-6 parts by weight is added to enable the crystal flash particles to form high-brightness glass bodies, so that the brightness of the crystal flash dry particles is improved.
In some embodiments, the particle size of the screened flash dry particles is 80-150 mesh, so that the screened flash dry particles have a better flash effect. This is because an excessively large particle diameter produces an adverse interface effect; and the grain size is too small, so that the crystal flash dry grains are easily dissolved by the mixed transparent glaze or transparent dry grains and lose the crystal flash effect.

The invention provides a crystal flash dry particle which comprises the following raw materials in parts by weight: 0.3-8 parts of zirconite, 55-68 parts of quartz, 18-45 parts of boric acid, 0-5 parts of corundum, 4-10 parts of alkali metal oxide and 0.2-6 parts of lithium carbonate, wherein the zirconite is a byproduct of invaded rock.
As shown in fig. 1, the zircon crystals in this embodiment are in the shape of a square double cone, a column, or a plate, and when the zircon crystals are used as crystal flashing grains, trigeminal grain boundaries are formed between the grains, so that the reflection characteristics are enhanced by the cooperation of diffuse reflection at crystal flashing grain boundaries and reflection at the trigeminal grain boundary surfaces, and different-angle flashing effects are achieved. Specifically, the zircon is selected from one or more of gabbros, amphiboles and granites. As shown in fig. 2 a, the developed tetragonal bipyramid and oscillation ring zone in granite zircon provides a good glittering effect. As shown in fig. 2 b, zircon in gabbros takes the shape of long column and girdle on the surface of the development board, so that it has good sparkling effect. And as shown in c in fig. 2, the length and width of the zircon in the clastic rock are basically almost the same, and the zircon has a certain rounding, is in a muddy circular shape, has small particles and basically has no flashing effect.
Further, among the above raw materials, quartz is used as a glass former oxide, which can improve many properties of the flash dried particles, such as increasing the melting temperature, increasing the viscosity of the glaze, increasing the resistance of the flash dried particles to water-solubility and chemical attack, increasing the mechanical strength and hardness of the flash dried particles, decreasing the expansion coefficient of the flash dried particles, and the like. The boric acid is used as a strong fluxing agent, a proper amount of boric acid is added, the melting temperature of the crystal flash dry particles can be obviously reduced, the expansion coefficient of the crystal flash dry particles is reduced, the refractive index of the crystal flash dry particles to ceramics is increased, the glossiness is improved, the hardness and the elasticity of a glaze surface are improved, 18-45% of boric acid is added, the boric acid can participate in a silica structure to form a borosilicate glass network, and therefore the crystal flash dry particles have a very low expansion coefficient. When the crystal flashing dry particles are mixed with the glaze layer material on the surface of the green brick, larger expansion coefficient gradient difference is generated, so that controllable crystal boundaries are generated around the crystal flashing dry particles, when light rays irradiate, reflection and refraction are generated on the interface, and the antifouling performance and the modulus of rupture of the crystal flashing ceramic brick can be improved. Corundum is used as a network intermediate oxide, and can usually capture free oxygen to form four coordination to enter a silicon-oxygen network in the process of melting flash dry grains of crystal, so that the network structure of glass is reinforced, the hardness and mechanical strength of the glaze are improved, the chemical corrosion resistance of the glaze is improved, the expansion coefficient of the flash dry grains of crystal is reduced, the vitrification capacity is improved and the like. The alkali metal oxide is used as a network exosome oxide, has a strong net breaking effect in the melting process of the crystal flash dry particles, and can obviously reduce the melting temperature and viscosity, chemical stability and mechanical strength of the crystal flash dry particles. Wherein the alkali metal oxide comprises potassium oxide and sodium oxide. The lithium carbonate is used as a strong fluxing agent, and can improve the glossiness, chemical stability and elasticity of the crystal flashing dry particles, so that the crystal flashing ceramic tile has good glossiness.
In one implementation, the grain diameter of the prepared crystal flash dry grains is 80-150 meshes, so that the crystal flash dry grains have a good flash effect. When the dry particle size is larger than 150 mesh, an adverse interface effect is generated; and when the particle size of the dry particles is less than 80 meshes, the crystal flash dry particles are easily dissolved by the mixed transparent glaze or transparent dry particles, and the flash effect is lost.
The chemical components of the crystal flash dry particles comprise the following components in percentage by weight: ZrO (ZrO)2：0.3~8%、SiO2：65～80%、Al2O3：0～6%、B2O3: 10 to 25%, 5 to 12% of an alkali metal oxide, and Li2O: 0.1-3%, loss on ignition: less than 0.6%. Wherein in the alkali metal oxide, the weight ratio of potassium oxide to sodium oxide is 2-6: 3 to 8.
