Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of building decoration, and particularly relates to a preparation method of combined dry particle clusters, and a ceramic rock plate with a decorative effect of a heterogeneous and heterogeneous pattern and a preparation method thereof. BACKGROUND

[0002] The prior art mainly uses an inkjet printer to spray glue and then uses a dry particle distribution machine to distribute dry particles to perform dry particle decoration. Due to the limitation of the production line and the cost control principle, a building ceramic enterprise can only perform decoration of a single dry particle when only one dry particle distribution device is installed, which greatly limits the customized design of the decorative effect of the ceramic product.

[0003] Chinese Patent ZL 202210632867.3 relates to a white polycrystal dry particle ceramic rock plate and a preparation method thereof. An effect pattern is inkjet printed on the surface of a body after a base glaze is applied to the surface of the body, an isolation glaze is applied to the surface of the body after the effect pattern is inkjet printed, and white polycrystal dry particles are positioned and distributed on the surface of the body after the isolation glaze is applied. The product formed after being fired has a decorative effect, and the product has single white crystal flowers of different shapes, but the decorative effect is single.

[0004] Chinese Patent ZL 202411019036.4 relates to a preparation method of a sinterless dry particle, and a sinterless dry particle ceramic tile and a preparation method thereof.

[0027] The present application is further illustrated by the following examples, which should be understood as merely illustrative of the present application, but not limiting the present application. Unless otherwise specified, each percentage content refers to mass percentage content.

[0028] The following exemplary illustrates the preparation method of the ceramic rock plate with a decorative effect of a heterochromatic and heteromorphic pattern.

[0029] The rock plate blank is pressed to obtain a body. The body can be dry-pressed. The chemical composition and raw material composition of the rock plate blank are not limited and a rock plate blank commonly used in the art can be used. As an example, the chemical composition of the rock plate blank can include, in mass percent, loss on ignition: 4% to 4.8%, SiO2: 60% to 65%, Al2O3: 20% to 22%, Fe2O3: 0.1% to 0.5%, TiO2: 0.05% to 0.3%, CaO: 0.4% to 0.5%, MgO: 0.5% to 1%, K2O: 2% to 3%, Na2O: 3% to 4%.

[0030] The particle size distribution of the rock plate blank has an effect on the body forming performance. The particle size distribution of the rock plate blank can include, in mass percent, 30 mesh or more: 20% to 25%, 30 to 80 mesh: 60% to 70%, 80 mesh or less: ≦6%. 30 mesh or more refers to the portion that remains on a 30 mesh screen. 80 mesh or less refers to the portion that passes through an 80 mesh screen. The moisture content of the rock plate blank is preferably 8.5±3 wt%.

[0031] The body is dried. The drying can be performed in a drying kiln.

[0032] A base glaze is applied to the surface of the dried body. A base glaze commonly used in the art can be used. For example, the chemical composition of the base glaze includes, in mass percent, SiO2: 61% to 65%, Al2O3: 19% to 23%, K2O: 3% to 4%, Na2O: 3.1% to 3.8%, CaO: 0.5% to 1%, MgO: 0.5% to 1%, ZrO2: 3.2% to 9.6%, loss on ignition: 1.5% to 2%.

[0033] The base glaze can be applied by spraying. As an example, the specific gravity of the base glaze is 1.3 to 1.5 g / cm3and the amount of the base glaze applied is 500 to 600 g / m2. 3 2 If the amount of the base glaze applied is too low, the base color and defects of the body cannot be covered and pinholes and air bubbles can occur in the glaze layer. If the amount of the base glaze applied is too high, the moisture content of the body entering the kiln is too high, which causes the moisture to be removed too quickly and the body to break.

[0034] The body to which the base glaze is applied is dried.

[0035] An ordinary ink pattern is printed on the surface of the body to which the base glaze is applied. The texture and color of the ordinary ink pattern can be adapted as needed.

[0036] ​The combined dry granule cluster is formed by at least one or two of the base dry granule, the colored dry granule, and the low-temperature dry granule. For example, the combined dry granule cluster is a combined cluster of the base dry granule and the colored dry granule, or a combined cluster of the colored dry granule and the low-temperature dry granule, or a combined cluster of different colored dry granules, or a combined cluster of the base dry granule and the low-temperature dry granule, or a combined cluster of the base dry granule, the colored dry granule, and the low-temperature dry granule. Preferably, the combined dry granule cluster is a combined dry granule cluster formed by at least one of the low-temperature dry granule and the base dry granule or the colored dry granule. In some embodiments, the combined dry granule cluster is a combined dry granule cluster formed by 30% to 60% of the base dry granule and / or the colored dry granule and 40% to 70% of the low-temperature dry granule in terms of mass percentage.

[0037] In an optional embodiment, the mineral composition of the base dry granule includes, in terms of mass percentage, 5% to 10% of kaolin, 20% to 30% of zinc oxide, 45% to 70% of high-zinc high-calcium frit, and 5% to 15% of wollastonite. The melting temperature of the base dry granule can be 1100 to 1150°C. The chemical composition of the high-zinc high-calcium frit includes, in terms of mass percentage, 50% to 60% of SiO2, 5% to 10% of Al2O3, 5% to 15% (preferably 10% to 15%) of CaO, 1% to 5% of MgO, 3% to 6% of K2O, 1% to 3% of Na2O, and 5% to 10% of ZnO. As an example, the chemical composition of the high-zinc high-calcium frit includes, in terms of mass percentage, 0 to 0.5% (for example, 0.01% to 0.5%) of loss on ignition, 50% to 60% of SiO2, 5% to 10% of Al2O3, 5% to 15% (preferably 10% to 15%) of CaO, 1% to 5% of MgO, 3% to 6% of K2O, 1% to 3% of Na2O, and 5% to 10% of ZnO. The high-zinc high-calcium frit can reduce the high-temperature viscosity of the base dry granule and provide zinc, which has a low surface tension, to form a difference between the surface tension of the base dry granule and the surface tension of the transparent glaze, thereby having better flowability.

[0038] The chemical composition of the base dry granule can include, by mass percent, Si02: 45-58%, AI2O3: 5-10%, Fe203: 0.1-0.3%, Ti02: 0.01-0.03%, CaO: 5-15%, MgO: 1-3%, K20: 3-5%, Na20: 1-2%, ZnO: 25-35%. In an alternative embodiment, the chemical composition of the base dry granule includes, by mass percent, loss on ignition: 0-2% (e.g., 1-2%), Si02: 45-58%, AI2O3: 5-10%, Fe203: 0.1-0.3%, Ti02: 0.01-0.03%, CaO: 5-15%, MgO: 1-3%, K20: 3-5%, Na20: 1-2%, ZnO: 25-35%.

[0039] In an alternative embodiment, the colored dry granule includes a base dry granule and a colorant. The colorant includes, but is not limited to, CuO, Mn02, Co203, and the like. The mass addition of the colorant can be 0.5-2% of the base dry granule.

[0040] The chemical composition of the low temperature dry granule can include, by mass percent, Si02: 50-60%, AI2O3: 5-10%, CaO: 10-15%, MgO: 1-3%, K20: 1-3%, Na20: 1-4%, ZnO: 5-10%, BaO: 5-10%, B203: 5-10%. In an alternative embodiment, the chemical composition of the low temperature dry granule includes, by mass percent, loss on ignition: 0-0.5% (e.g., 0.01-0.5%), Si02: 50-60%, AI2O3: 5-10%, CaO: 10-15%, MgO: 1-3%, K20: 1-3%, Na20: 1-4%, ZnO: 5-10%, BaO: 5-10%, B203: 5-10%. The melting temperature of the low temperature dry granule can be 1080-1100°C. If the melting temperature of the low temperature dry granule is too high, it will not be able to attack the base dry granule. If the melting temperature of the low temperature dry granule is too low, it will affect the glaze quality and produce air holes.

[0041] The combined dry particle cluster can be made by the following method. The mineral raw materials of the dry particles are mixed uniformly to obtain a glass liquid by high-temperature melting. The melting temperature can be 1200-1300°C. The glass liquid is drawn into glass filaments by a crucible method. For example, the glass liquid is placed in a crucible, the crucible is placed on a filament drawing machine, and the initial drawing tension at the start of drawing is controlled by adjusting the speed of the filament drawing machine. After the drawing starts, the tension is gradually increased, and the necessary control is performed on the filament drawing machine to draw the glass filaments with the desired diameter. The diameter of the glass filaments can be, for example, 0.5-2 mm. The glass filaments are subjected to sizing treatment. In an optional embodiment, the raw material composition of the sizing agent includes, by mass percentage, PVA 5-10%, water glass 40-60%, defoaming agent 1-2%, emulsifier 0.3-1%, and water 27-50%. The composition of PVA, water glass, defoaming agent, and emulsifier is not limited and any commonly used reagent in the art can be used. In an optional technical solution, the PVA is water-soluble polyvinyl alcohol with an alcoholysis degree of ≤95%; the modulus of the water glass is 2.6-3.3; and the emulsifier includes, but is not limited to, one of OP-10, NP-10, tween-80, and AEO-9. The configuration temperature of the sizing agent can be 50-80°C. The glass filaments of the dry particles are arranged in a specific design pattern and placed in a drying box for heat treatment to realize the clustering of different dry particles. The purpose of the heat treatment is to solidify the sizing agent. The heat treatment temperature can be 100-160°C, and the heat treatment time can be 1-5 h. Then, the dry particles after clustering are cut to obtain the combined dry particle cluster. The length of the combined dry particle cluster can be 0.2-0.5 mm.

[0042] The combined dry particle cluster is positioned and applied by spraying an inkjet-printed glue pattern. The inkjet-printed glue pattern can use two inkjet channels, for example, the glue pattern gray scale of each channel is 100%. In this way, the glue pattern has sufficient adhesion to firmly bond the combined dry particle cluster. After the combined dry particle cluster is applied by the glue dry particle machine, the excess combined dry particle cluster is sucked away by a collection device.

[0043] A transparent glaze is applied to the surface of the green body after the combined dry particle cluster is applied. In an optional embodiment, the chemical composition of the transparent glaze includes, by mass percentage, loss on ignition: 5-10%, SiO2: 45-60%, Al2O3: 15-20%, Fe2O3: 0.1-0.3%, TiO2: 0.1-0.3%, CaO: 5-10%, MgO: 3-6%, K2O: 0.5-1%, Na2O: 2-5%, and ZnO: 2-5%. The melting temperature of the transparent glaze can be 1130-1160°C. A too high melting temperature of the transparent glaze will cause the base dry particles to remain in a granular form. A too low melting temperature of the transparent glaze will cause pores on the glaze surface, resulting in poor surface quality.

[0044] The transparent glaze can be applied by spraying. For example, the specific gravity of the transparent glaze is 1.55-1.6 g / cm 3 , and the glazing amount is 500-600 g / m 2 .

[0045] The body after the transparent glaze is fired in a kiln to obtain a ceramic rock plate with a heterochromatic and heteromorphic pattern decoration effect. In an optional embodiment, the firing temperature is 1170-1200℃, and the firing time is 40-60 min. The body after the transparent glaze can be dried before firing.

[0046] Edge grinding is performed after firing. After edge grinding, the product is packed and stored.

[0047] The present application prepares a plurality of dry particles into a combined bundle in a special way, and the product after firing has different pattern effects formed by the interweaving of a plurality of dry particles, and the pattern is more rich. In particular, the combined bundle prepared by using low-temperature dry particles and basic dry particles and / or colored dry particles, the low-temperature dry particles erode other dry particles during the firing process, forming special patterns such as crescent shapes, and having better decoration.

[0048] The following examples are further listed to illustrate the present application in detail. It should also be understood that the following examples are only used to further illustrate the present application, and cannot be understood as limiting the protection scope of the present application. Some non-essential improvements and adjustments made by those skilled in the art based on the above content of the present application all belong to the protection scope of the present application. The specific process parameters in the following examples are only one example in the appropriate range, i.e. those skilled in the art can select within the appropriate range through the description herein, and are not limited to the specific values in the following examples.

[0050] The preparation method of the ceramic rock plate with a heterochromatic and heteromorphic pattern decoration effect comprises:

[0051] Step 1. Dry pressing the rock plate blank to obtain a body and drying the body.

Then adopt the dry granulator to apply the combined dry granule cluster, and use the collection device to suck away the excess combined dry granule cluster after the application is completed. Among them, the combined dry granule cluster is a combined dry granule cluster formed by 50wt% colored dry granule and 50wt% basic dry granule.

[0055] After the mineral raw materials of the basic dry granule are uniformly mixed, high-temperature melting at 1250℃ is performed, and glass filaments with a diameter of 1 mm are prepared by using crucible drawing, and then the glass filaments are subjected to sizing treatment.

The initial melting temperature of the basic dry granule is 1120℃.

[0056] After the mineral raw materials of the low-temperature dry granule are uniformly mixed, high-temperature melting at 1250℃ is performed, and glass filaments with a diameter of 1 mm are prepared by using crucible drawing, and then the glass filaments are subjected to sizing treatment. The chemical composition of the low-temperature dry granule includes, in terms of mass percentage, loss on ignition: 0.2%, SiO2: 54.8%, Al2O3: 7%, CaO: 11%, MgO: 2%, K2O: 1%, Na2O: 4%, ZnO: 5%, BaO: 10%, and B2O3: 5%. The initial melting temperature of the low-temperature dry granule is 1090℃.

[0057] The corresponding glass filaments of the sized basic dry granule and low-temperature dry granule are arranged in a specific design pattern, and are placed in a drying box for heat treatment to realize the clustering of different dry granules; then the clustered dry granules are cut to prepare a combined dry granule cluster. The length of the combined dry granule cluster is 0.5 mm. The heat treatment temperature is 150℃, and the time is 5h. The raw material composition of the sizing agent includes, in terms of mass percentage, PVA 7%, water glass 53%, defoaming agent 1.5%, emulsifier 0.5%, and water 38%. The PVA is water-soluble polyvinyl alcohol with an alcoholysis degree ≤95%. The modulus of the water glass is 2.6. The emulsifier is tween-80. The preparation temperature of the sizing agent is 80℃.

[0058] Step 5. Apply transparent glaze on the surface of the body with the combination of dry granules cluster glaze.

The transparent glaze is applied by spraying. The specific gravity of the transparent glaze is 1.55 g / cm 3 , and the glaze application amount is 550 g / m 2 . The initial melting temperature of the transparent glaze is 1140°C.

[0059] Step 6. Firing. Dry the body with transparent glaze and then fire in the kiln after drying. The firing temperature is 1180°C, and the firing time is 50 min.

[0060] Step 7. After firing, edge grinding, packaging, and storage.

[0061] Figure 1 The brick surface effect diagram of Example 1. It can be seen that the low-temperature dry granules effectively erode the colored dry granules, forming a crescent-shaped heterochromatic and heteromorphic effect.

[0062] Example 2

[0063] Basically the same as Example 1, the only difference is that the combination of dry granules cluster is formed by 50% base dry granules and 50% colored dry granules.

[0064] Figure 2 The brick surface effect diagram of Example 2. It can be seen that the base dry granules and the colored dry granules are mutually wetting, but no erosion occurs between the two, so no heteromorphic effect is generated.

[0065] Comparative Example 1

[0066] Basically the same as Example 1, the only difference is that the chemical composition of the transparent glaze includes, by mass percentage, loss on ignition: 4.78%, SiO2: 55%, Al2O3: 20%, Fe2O3: 0.2%, TiO2: 0.02%, CaO: 5%, MgO: 3%, K2O: 5%, Na2O: 5%, ZnO: 2%. The initial melting temperature of the transparent glaze is 1180°C.

[0067] Figure 3 The brick surface effect diagram of Comparative Example 1. Due to the high melting temperature and large viscosity of the transparent glaze, the base dry granules cannot spread, resulting in the dry granules on the brick surface after firing still maintaining a granular shape and failing to generate a heteromorphic pattern.

[0068] Comparative Example 2

[0069] The low temperature dry granules have a chemical composition including, by mass percentage, loss on ignition: 0.5%, SiO2: 54.5%, Al2O3: 15%, CaO: 5%, MgO: 3%, K2O: 1%, Na2O: 5%, ZnO: 2%, BaO: 10%, B2O3: 4%. The initial melting temperature of the low temperature dry granules is 1140°C.

[0070] This comparative example does not form a special shaped pattern because the low temperature dry granules cannot effectively attack the colored dry granules due to the high melting temperature of the low temperature dry granules.
