Description

The glaze of the ceramic in the process of firing is also very important. The ceramic industry also focuses on the development of functional and practical glazes. Different effects will be produced on the same body due to different glazes on the glaze surface. The touch and visual perception of different glazes will also affect the choice of consumers.

It is dense, impermeable to water and air, and can resist acid and alkali erosion. It is usually made of natural mineral raw materials and some chemical raw materials, which are melted at high temperature to form a glassy layer with luster. Glaze has various weights. Glaze with flash effect is called flash glaze. It has a metallic mirror-like reflection effect on the incident light. When observing the finished flash glaze, metallic reflection can be seen under a certain light incidence angle. This metallic reflection is different from that of metallic luster glaze, which has the characteristics of mirror reflection.

[0004] The existing flash glaze has the technical problems of single flash point texture, uneven and not delicate flash point distribution, etc. due to the difference in raw material selection and preparation process, which limits its application. SUMMARY

[0044] Figure 2 is the glaze effect diagram of the enamel tile prepared in embodiment 4 of the present application. DETAILED DESCRIPTION

[0045] A preparation method of an enamel tile with bright and matte composite flash effect, comprising the following steps:

[0046] A. preparing a body layer;

[0047] B. inkjet printing matte ink on the surface of the body layer to obtain a matte ink layer;

[0048] The matte ink comprises the following chemical components in percentage of mass: SiO2 45-48%, Al2O3 20-25%, Fe2O3 0.01-0.1%, TiO2 0.01-0.1%, CaO 18-21%, MgO 0.1-1%, K2O 0.5-1.8%, Na2O 5-7% and ZnO 4-6.5%;

[0049] C. applying a metal flash glaze on the surface of the matte ink layer to obtain a metal flash glaze layer;

[0050] The metal flash glaze comprises the following raw materials in parts of mass: kaolin 2-8 parts and metal flash frit 90-98 parts; and the metal flash frit comprises the following raw materials in parts of mass: kaolin 12-20 parts, calcined alumina 2-5 parts, wollastonite 8-15 parts, zinc oxide 4-8 parts, calcined talc 2-8 parts, potassium feldspar 20-30 parts, sodium feldspar 10-20 parts, zircon 8-15 parts, cerium oxide 3-6 parts, red lead 3-8 parts and barium carbonate 1-5 parts;

[0051] D. after drying, putting into a kiln for firing to obtain a glazed tile with bright and matte composite flash effect.

[0052] Firstly, in order to improve the metal texture of the metal flash glaze, the present application proposes a metal flash frit, which is essentially a melt with cerium oxide and zirconium oxide wrapped in the glass phase. Then, by compounding with kaolin, the cerium ions in the frit are precipitated and form cerium oxide crystals with a refractive index of 2.44, the zirconium ions are precipitated and form cubic zirconium oxide crystals with a refractive index of 2.14, and the glass phase in the frit generates a glass phase with a refractive index of 1.54, thereby generating crystals with three different refractive indexes in the glaze layer. Since the cerium oxide crystal is a face-centered cubic crystal structure, its crystal plane parallel to the glaze surface has a low interfacial energy, so it shows strong anisotropy in the growth process and has good mirror reflection characteristics for visible light, thereby forming strong mirror metal reflection; the cubic zirconium oxide crystal can form good scattering effect on incident light, and the above two kinds of crystals cooperate with the glass phase to effectively form strong metal flash effect on the surface of the glaze layer.

[0053] In addition, it should be noted that the extremely high content of metal flash frit in the glaze formula not only ensures that the glaze layer has strong metal texture, but also helps to ensure that the metal texture is evenly distributed in the glaze layer.

[0054] Further, in order to enrich the glaze brick with a shiny texture, the present scheme further adds a matte ink layer between the body layer and the metal shiny glaze layer, and the matte digital ink is printed on the surface of the body layer in a preset pattern by inkjet printing, so that the metal shiny brick surface after firing can reveal a shiny texture, and a combined shiny effect of bright light and matte light is presented.

[0055] Specifically, in order to achieve the above-mentioned combined shiny effect, the matte ink in the present scheme adopts a high-calcium non-shiny formula system, which has a high content of calcium oxide, which is beneficial to the precipitation of a hierarchical structure with anorthite microcrystals as the main crystal in the matte ink layer during the firing process, and the glossiness is extremely low, which is beneficial to enriching the visual effect of the glaze brick in cooperation with the metal shiny glaze layer with strong metal shiny effect.

[0056] In addition, from the formula structure of the matte ink and the metal shiny glaze, the high-temperature viscosity of the matte ink is higher than that of the metal shiny glaze, so that during the firing process, the pattern of the matte ink layer formed by inkjet printing can be greatly preserved, while the metal shiny glaze is leveled on the concave-convex matte ink layer and forms a thin protective glaze layer, so that the design of the above-mentioned formula structure can improve the anti-skid performance of the glaze brick to a certain extent.

[0057] Further, according to mass fraction, the matte ink includes raw materials: kaolin 15-25 parts, quartz 20-35 parts, alumina 10-15 parts, sodium feldspar 8-15 parts, calcined talc 0.5-3 parts, calcite 25-35 parts, sodium carbonate 5-10 parts, and zinc oxide 3-6 parts.

[0058] In one embodiment of the present technical scheme, the matte ink can be configured by the above-mentioned proportioned raw materials, which are easy to obtain and have low cost.

[0059] Further, the method further includes step E, and step E is located between step A and step B.

[0060] A, preparing a body layer;

[0061] E, applying a base glaze to the surface of the body layer to obtain a base glaze layer;

[0062] According to mass fraction, the base glaze includes the following raw materials: kaolin 6-10 parts, alumina 2-8 parts, nepheline 35-42 parts, sodium feldspar 2-10 parts, calcium strontium barium frit 18-25 parts, and zirconium silicate 18-22 parts.

[0063] The calcium-strontium-barium frit comprises the following chemical components in percentage of mass: SiO2 40-45%, Al2O3 19-25%, Fe2O3 0.01-0.1%, TiO2 0.01-0.1%, CaO 6-8%, MgO 1-3%, K2O 0.5-1.5%, Na2O 0.01-0.1%, ZnO 2-4%, BaO 15-22% and SrO 5-7%;

[0064] B. printing the matte ink on the surface of the base glaze layer to obtain a matte ink layer.

[0065] In order to control the production cost of the ceramic tile, the whiteness of the body layer in the existing glazed tile is generally low. In order to prevent the low-whiteness body layer from affecting the expression of the decorative function of the glaze layer, a base glaze layer is generally added between the body layer and the decorative glaze layer to cover the body layer. In the prior art, the conventional base glaze formula system is a potassium-sodium system or a calcium-magnesium system. The base glaze of the above formula system is generally not matched with the formula system of the sparkling glaze, which is not conducive to the presentation of the sparkling effect. That is, although the existing base glaze can cover the low-whiteness body layer to a certain extent, it has very limited help for the presentation of the sparkling effect of the sparkling glaze.

[0066] Therefore, in order to make the composite sparkling effect best presented on the surface of the ceramic tile, the base glaze layer is additionally arranged on the top of the body layer, and the separation of the glass phase and the crystal phase in the matte ink layer and the metallic sparkling glaze layer is promoted by adjusting the formula system of the base glaze, so that the materials with different refractive indexes produce refraction and interference under the condition of light, thereby presenting a more intense composite sparkling effect.

[0067] Specifically, the frit with high content of CaO and BaO is introduced into the raw material formula of the base glaze, which is beneficial to the precipitation of the glaze layer with microcrystals of calcium feldspar and barium feldspar as the main crystals in the firing process, thereby promoting the separation of the glass phase and the crystal in the matte ink layer and the metallic sparkling glaze layer, and enhancing the composite texture of the sparkling effect. In addition, the initial melting point of the base glaze can be improved, which plays a role in improving the high-temperature viscosity of the glaze layer and provides a basis for the base glaze as a mold glaze layer of the digital mold ceramic tile. More specifically, the formula system of the frit also contains a large amount of SrO. Since the atomic radius of strontium oxide is large, it can further improve the high-temperature viscosity of the glaze on the one hand, and promote the precipitation of the divalent ion crystals (i.e. calcium feldspar and barium feldspar) in the glaze layer on the other hand, thereby ensuring the auxiliary effect of the base glaze layer on the presentation of the sparkling effect of the matte ink layer and the metallic sparkling glaze layer.

[0068] In the raw material formula of the base glaze, in addition to the introduction of the frit with the specific formula structure, a large amount of zirconium silicate is added. The large amount of zirconium silicate can make the glaze layer generate zirconia crystals after firing, thereby improving the whiteness of the base glaze layer, helping to highlight the flashing effect of the metal flashing glaze layer, and achieving the purpose of covering the body layer; in addition, it can also improve the high temperature viscosity of the glaze layer to a certain extent, and when it is used as a mold texture layer, it can greatly retain the pre-designed texture morphology, providing rich decorative performance for the glazed tile. Further, the scheme also specially adds nepheline in the raw material formula of the base glaze. Compared with the conventional potassium sodium feldspar, the expansion coefficient of the nepheline is smaller, and the introduction of a large amount of nepheline can adjust the expansion coefficient of the glaze layer, thereby improving the flatness of the glaze layer.

[0069] Preferably, according to the mass fraction, the base glaze comprises the following raw materials: kaolin 8 parts, alumina 4 parts, nepheline 39 parts, sodium feldspar 6 parts, calcium strontium barium frit 22 parts and zirconium silicate 20 parts.

[0070] Further, according to the mass fraction, the calcium strontium barium frit comprises the following raw materials: kaolin 25 parts, calcined alumina 8 parts, quartz 21 parts, calcined talc 4 parts, barium carbonate 20 parts, strontium carbonate 8 parts, calcite 12 parts and zinc oxide 2 parts.

[0071] As a preferred embodiment of the present scheme, the calcium strontium barium frit can be configured by the above-mentioned raw materials with the above-mentioned proportions, which is easy to obtain and has low production cost.

[0072] Further, the firing curve of the calcium strontium barium frit is as follows:

[0073] From room temperature to 500℃, the time consumption is 2h;

[0074] From 500℃ to 1100℃, the time consumption is 1h;

[0075] From 1100℃ to 1530℃, the time consumption is 1h;

[0076] At 1530℃, the time consumption is 0.5h.

[0077] Further, according to the mass percentage, the content of zirconia in the zircon sand is 60-66%.

[0078] Specifically, the scheme preferably uses zircon sand with a zirconia content of 60-66% as the formula raw material of the metal flashing frit, which is more conducive to promoting the formation of zirconia crystals in the glaze layer.

[0079] Further, the metal flash frit comprises, in terms of mass fraction, the following raw materials: 15 parts of kaolin, 2.5 parts of calcined alumina, 10 parts of wollastonite, 6 parts of zinc oxide, 5 parts of calcined talc, 25 parts of potassium feldspar, 15 parts of sodium feldspar, 10.5 parts of zircon, 4 parts of cerium oxide, 5 parts of red lead, and 2 parts of barium carbonate;

[0080] The metal flash glaze comprises, in terms of mass fraction, the following raw materials: 4 parts of kaolin and 96 parts of the metal flash frit.

[0081] As a preferred embodiment of the above embodiment, the application further provides an optimal raw material ratio of a metal flash frit and a glaze thereof, which is beneficial to generate a strong metallic texture on the surface of the glaze layer.

[0082] Preferably, the firing curve of the metal flash frit is as follows:

[0083] Rising from room temperature to 500°C in 2 hours;

[0084] Rising from 500°C to 1100°C in 1 hour;

[0085] Rising from 1100°C to 1500°C in 1 hour;

[0086] Keeping at 1500°C for 1 hour.

[0087] Further, the application further comprises a step F, and the step F is located between the step A and the step E.

[0088] A, preparing a body layer;

[0089] F, inkjet printing the mold ink according to a preset pattern on the surface of the body layer to obtain a mold ink layer;

[0090] E, applying a base glaze on the surface of the mold ink layer to obtain a base glaze layer, and the base glaze layer has a concave-convex mold texture formed by being pushed away by the mold ink layer.

[0091] Due to the setting of the base glaze formula structure, the base glaze has a high high-temperature viscosity, and thus can be used to form a mold texture layer with a concave-convex mold texture.

[0092] It should be noted that the digital mold ceramic tiles with a concave-convex effect texture in the prior art generally use mold ink and glaze in combination to form a mold effect. The mechanism of generating the mold texture is that the mold ink is oily, and the glaze is aqueous. The tension is generated when the oily ink and the aqueous glaze are in contact. The ink with a texture pattern physically pushes away the subsequent aqueous glaze, thereby forming a concave-convex mold texture.

[0093] Further, the application further comprises a step G, and the step G is located between the step E and the step B.

[0094] E. applying a base glaze to the surface of the body layer to obtain a base glaze layer;

[0095] G. inkjet printing color ink on the surface of the base glaze layer according to a preset pattern to obtain a color ink layer;

[0096] B. inkjet printing matte ink on the surface of the color ink layer to obtain a matte ink layer.

[0097] In order to improve the decorative effect of the glazed tile, a color ink layer can also be added between the base glaze layer and the matte ink layer, so that the color of the color ink layer is presented on the tile surface of the glazed tile through the matte ink layer and the metal flash glaze layer, so as to better meet the viewing needs of consumers.

[0098] A glazed tile with bright and matte combined flash effect is prepared by using the preparation method of the metal flash glazed tile.

[0099] Specifically, the metal flash glazed tile prepared by the preparation method of the present application has good hardness, anti-fouling and anti-skid properties in addition to the combined flash effect and texture of bright and matte, so that the metal flash glazed tile has both decorative and practical properties, and is more conducive to meeting the use needs of consumers.
