Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The technical scheme of the scheme is further described through the specific embodiments with reference to the accompanying drawings.
A preparation process of a concave texture pearl glaze comprises the following steps:
(1) Applying ground enamel on the green body;
the ground glaze is a well-known ground glaze and is an intermediate layer porcelain glaze directly combined with the ground glaze in the process.
(2) Applying a matte surface glaze on the ground glaze cloth to prepare a matte surface layer;
after the matte overglaze is sintered to form a matte glaze surface, the matte overglaze surface can be coated with ink;
(3) Printing ink on the matte surface layer;
(4) Applying pearl protection glaze on the matte surface layer, drying and sintering;
the main effect of drying is that the color ink is more oily when being superimposed with the engraving ink, and the glaze layer is more water and dried to prevent the glaze surface from being fried when one layer of pearl protection glaze is sprayed.
In the step (2), raw materials of the matte overglaze comprise the following components in percentage by mass: 35-45% of potassium feldspar, 10-15% of albite, 4-10% of water-washed kaolin, 10-20% of calcined kaolin, 5-10% of quartz, 4-10% of calcined alumina, 4-8% of talcum, 5-10% of limestone and 3-8% of zirconium silicate; according to the ingredients, the matte glaze firing temperature is high, and the glossiness range can be 8-10 degrees; the glossiness of the common matte glaze is generally 18-28 degrees; the matte glaze with the scheme has better hand feeling than the conventional matte glaze.
In the optimal embodiment, the chemical components of the matte surface glaze comprise SiO according to the mass percent 2 45～55％、Al 2 O 3 17～22％、K 2 O 2～3％、Na 2 O 2～3％、CaO 7～11％、MgO 1～2％、ZrO 2 3-8% and the balance oxide impurities;
in the step (3), printing color ink firstly and printing engraving ink finally;
the color ink and the engraving ink are known inks;
in the step (4), the raw materials of the pearl protection glaze comprise, by mass, 35-45% of potassium feldspar, 10-15% of albite, 6-12% of water-washed kaolin, 10-20% of calcined kaolin, 5-10% of quartz, 3-6% of calcined alumina, 4-8% of talcum and 5-10% of limestone.
According to the proportion, in the optimal embodiment, the chemical components of the pearl protection glaze comprise 50-65% of SiO by mass percent 2 11-18% of Al 2 O 3 2 to 7 percent of K 2 O, na 0.05-1.5% 2 O, 5-8% CaO, 0.5-1.5% MgO, 1-5% P 2 O 5 2 to 5 percent of ZnO, 4 to 8 percent of Ba0 and 0.5 to 2.5 percent of SrO. Wherein, the pearl protection glaze SiO 2 The content is high, so that the glaze melting point is high, the stereoscopic impression of the glaze surface is ensured, the refined carving ink is more oily than the color ink, the glaze discharging property is increased when the refined carving ink is burnt, the sinking effect of the glaze surface is more layered, the combination of the pearl protection glaze and the refined carving ink realizes the stereoscopic effect, and the stereoscopic effect is further richer and more stereoscopic.
The scheme provides a preparation process of a concave texture pearl glaze, which forms a matte surface layer on a matte glaze with a specific formula, and prints ink on the matte surface layer, wherein the pearl protection glaze and the engraving ink are organically combined through different channels of the same ink-jet machine, so that a concave clear texture with pearl color can be formed on the glaze, the appearance and the touch are both achieved, the problem that dense orange peel can easily appear on the glaze of a common soft glaze in the prior art, and the hand feeling effect of a concave discrete body is poor is solved.
Of course, the matte overglaze and the pearl protection glaze may also contain known reagents added in the glaze preparation process, for example, ball milling agents added during ball milling can be sodium carboxymethyl cellulose and/or sodium tripolyphosphate; sodium carboxymethylcellulose is generally 0.07 to 0.12 percent, and sodium tripolyphosphate is generally 0.3 to 0.5 percent.
Preferably, the color ink and the engraving ink are arranged in different channels of the same inkjet machine.
The number of channels of a common ink jet machine is required to be 8 channels or more, and besides color ink, only 1 channel of engraving ink is required to be arranged, so that a new process of the product with concave clear textures can be realized through simple glaze line equipment. The color ink and the engraving ink are arranged in different channels of the same ink-jet machine, the textures of the color ink and the engraving ink can be very easily and accurately aligned, so that the concave textures and the pattern textures are organically combined and completely fused into a whole, and the design and adjustment are very convenient.
Preferably, in the step (2), the glossiness of the matte surface layer is 8-10 °.
The glossiness of the matte surface layer can be adjusted according to the requirements of matte, for example, to 7-40 degrees, or 7-30 degrees, or 7-20 degrees, or 7-10 degrees; according to the scheme, the glossiness of the matte surface layer can be reduced, when the glossiness of the matte surface layer is the optimal 8-10 degrees, the concave texture pearl glaze can be soft, the final glossiness of the glaze can be 70-80 degrees, the organic combination of ink and pearl protection glaze is combined, the hand feeling of the glaze is kept smooth, fine and smooth and rich, the appearance is more similar to pearl luster and tone, and the texture of the glaze is further improved.
Preferably, in the step (4), the drying temperature of the pearl protection glaze is 80-100 ℃ and the drying time is 2-4 min.
Under reasonable drying temperature and drying time, the water of the pearl protection glaze can be discharged, so that excessive water of the pearl protection glaze can be avoided, and the glaze surface can be prevented from being fried.
The concave texture pearl glaze is prepared by the preparation process of the concave texture pearl glaze.
A ceramic, comprising; a blank body;
the surface of the green body is provided with a concave texture pearl glaze, and the concave texture pearl glaze is prepared by the preparation process of the concave texture pearl glaze.
The blank may be a substrate of a material known to have a decorative effect, such as ceramic tiles, rock plates, etc.
Preferably, the surface gloss of the ceramic is 70 to 80 °.
According to the scheme, the surface glossiness of the ceramic can be increased according to actual needs, so that the glossiness of the ceramic is improved; optimally, however, in order to solve the problem that the glaze surface of the common soft overglaze is difficult to prepare soft light and has three-dimensional hand feeling after the subsidence ink and the soft overglaze are applied, the scheme can debug the surface glossiness of the ceramic to be 70-80 degrees, and the glaze surface is mainly soft light surface in the range; the scheme can prevent the glaze from being dense with orange peel, and the sinking effect of the sinking ink can reach the three-dimensional hand feeling effect, so that the problem that the sinking ink and the soft surface in the prior art cannot reach the effect of being compatible is solved.
The application of the glaze in preparing the ceramics with the three-dimensional handfeel effect is that the glaze is prepared by the preparation process of the concave texture pearl glaze.

Description:
(1) As can be seen from the comparison of example a with comparative example D1, comparative example D1 did not perform step (2), and step (2) was the application of a matte overglaze; in the scheme, the laid matte surface glaze is sintered to form a matte surface layer, and the chemical components of the matte surface glaze are provided with SiO 2 、Al 2 O 3 、K 2 O、Na 2 O, caO, mgO and ZrO 2 The matte surface layer can be organically combined with the engraving ink at high temperature to generate different concave-convex effects so as to form a texture effect. Thus, the concave texture of the external appearance of comparative example D1 was not apparent, nor was there a clear three-dimensional effect, as shown in FIG. 4. Whereas example a performed cloth Shi Yaguang overglaze with clear recessed texture, a clear three-dimensional effect was seen in fig. 1. It is illustrated that the scheme requires that a matte overglaze be applied prior to inkjet printing to ensure clear texture and stereoscopic effect.
(2) As can be seen from the comparison of example A and comparative example D2, although performing step (2), uses a different matte overglaze than example A; this is because the matte overglaze of comparative example D2 was not organically combined with the engraving ink, and the texture effect of the final molding was not obvious, and there was no obvious three-dimensional effect, as shown in fig. 4. The raw materials of the matte surface glaze of the embodiment A are potassium feldspar, albite, water-washed kaolin, calcined kaolin, quartz, calcined alumina, talcum, limestone and zirconium silicate, and after sintering, the matte surface glaze can be organically combined with refined engraving ink, so that the concave texture of the glaze surface is clear, and the three-dimensional effect is obvious, as shown in figure 1.
(3) As can be seen from a comparison of example a and comparative example D3, comparative example D3 was provided with color ink and engraving ink in two different inkjet printers, respectively; in the scheme, the color ink and the engraving ink are arranged in different channels of the same ink-jet machine, and the texture of the color ink and the texture of the engraving ink can be accurately aligned, so that the concave texture and the pattern texture are organically combined and completely integrated; as can be seen from fig. 5, the comparative example D3 has a large concave texture and a pattern texture which are not integrated, and has a three-dimensional touch, but the concave texture is seriously affected, and the concave texture is not clear, and the appearance is affected. In the embodiment A, the color ink and the engraving ink are arranged in different channels of the same ink-jet machine, the concave texture and the pattern texture can be integrated, and the concave texture is clear.
(4) As can be seen from the comparison of the example A and the comparative example D4, the comparative example D4 adopts the protective glaze instead of the pearl protective glaze of the example A; in the scheme, siO in the ingredients of the pearl protection glaze 2 The content is high, the melting point of the glaze is high, and the stereoscopic impression of the glaze surface is ensured; meanwhile, the refined ink is more oily than the common ink, the glaze discharging property is increased during firing, the sinking effect of the glaze surface of the pearl protection glaze in the proportion is more layered, and the combination of the refined ink and the pearl protection glaze realizes richer and more stereoscopic effects. Therefore, the protective glaze used in comparative example D4 was not combined with the engraving ink, but had a clear texture, but had an insufficient layering and a poor stereoscopic effect, as shown in fig. 6. The pearl protection glaze formula of the scheme can be organically combined with refined carving ink to improve layering sense and stereoscopic effect.
In summary, the scheme forms a matte surface layer on the matte glaze with a specific formula, ink is printed on the matte surface layer, the pearl protection glaze and the engraving ink are organically combined through different channels of the same ink-jet machine, and concave clear textures with pearl colors can be formed on the glaze, so that the pearl protection glaze has both the look and feel.
The technical principle of the present solution is described above in connection with the specific embodiments. The description is only intended to explain the principles of the present solution and should not be construed in any way as limiting the scope of the present solution. Based on the explanations herein, other embodiments of the present solution will be apparent to those skilled in the art without undue burden, and such modifications will fall within the scope of the present solution.
