The present invention is described more fully below in order to facilitate an understanding of the present invention. This invention may be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
The examples are not to be construed as limiting the specific techniques or conditions described in the literature in this field or as per the specifications of the product. The reagents or apparatus used were conventional products commercially available without the manufacturer's attention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 and 2, the present invention provides a porcelain with composite decoration, comprising a porcelain substrate, a low Wen Mo water layer and a varnish layer; the porcelain body finished product is formed by secondary sintering of a porcelain body with low-temperature ink, and the varnish layer is formed by coating an organosilicon varnish on the surface of the glaze layer and solidifying;
the low-temperature ink layer is formed by sintering low Wen Moshui, and the low-temperature ink comprises the following components in parts by weight:
70 to 85 parts of common ceramic ink, 10 to 15 parts of pigment, 20 to 25 parts of ink frit, 2 to 5 parts of low-temperature ink dispersing agent, 1 to 3 parts of low-temperature ink defoaming agent, 0.2 to 0.5 part of leveling agent and 1 to 2 parts of auxiliary agent;
the organic silicon varnish comprises the following components in parts by weight:
30 to 60 parts of acrylic resin, 5 to 15 parts of epoxy resin, 10 to 20 parts of organosilicon oligomer, 10 to 19 parts of ethylene glycol ethyl ether acetate, 2 to 8 parts of isopropanol, 0.1 to 0.3 part of organosilicon varnish dispersing agent, 0.1 to 0.4 part of organosilicon varnish defoamer and 0.3 to 0.4 part of wetting agent.
The porcelain with composite decoration is used by matching the low temperature Mo Shuiceng with the varnish layer to form a corresponding low temperature Mo Shuiceng and the varnish layer, and the porcelain matrix is subjected to composite decoration, so that small quantity of personalized customization production can be carried out according to the textures and the colors required by customers, the product has the aesthetic property of pattern printing, and the requirements of users are met.
The low-temperature ink layer is formed by sintering low Wen Moshui, and the low-temperature ink components are compounded by using the conventional commercial common ceramic ink, so that the stability of the low-temperature ink is enhanced, the ink saturation is provided, and the color is more vivid; after being compounded, the low Wen Moshui has better color development effect at 600-800 ℃. Through the formula, the surface tension of the common ceramic ink on the porcelain matrix is improved, so that the low-temperature ink is more suitable for the porcelain matrix, and the color development effect of the printed pattern is improved. The advection agent can effectively reduce the surface tension of the coating liquid, and can promote the coating to form a smooth, even coating film in the drying and film forming process. When the low temperature ink is contacted with the porcelain substrate, a liquid-solid interface is formed in a very short time, and the amount of surfactant molecules transferred to the liquid-solid interface in a short time determines the final wetting effect. The low-temperature ink has the advantages that the low-temperature ink dispersing agent, the low Wen Moshui defoamer, the flatting agent and the auxiliary agent are matched, so that the dynamic surface tension of the low-temperature ink is small, the wetting effect is good, the combination degree of the low-temperature ink and a porcelain matrix is higher, the problems of pattern matte and pattern edge blurring are avoided, and the distortion of patterns is avoided. In addition, the viscosity of the common ceramic ink is regulated, the influence of the viscosity of the ceramic ink on the printing effect is avoided, and the blocking of spray holes caused by the overhigh viscosity is prevented.
The common ceramic inks are commercially available and include dao, kang Litai, merits, glory, trilobate, etc.
The varnish layer can improve the glossiness of the surface of the porcelain with composite decoration, and the overall glossiness of the surface of the porcelain with composite decoration is more uniform.
The silicone varnish dispersant, silicone varnish defoamer and wetting agent may be selected from the corresponding commercially available silicone dispersants, silicone defoamers and silicone wetting agents. The silicone varnish dispersant includes any one of polyacrylamide, polyethylene glycol and an ethoxy compound. The silicone varnish defoamer comprises a mineral oil defoamer or polyether modified silicone. The wetting agent comprises polyoxyethylene alkyl ether and polyether modified silicone oil.

Specifically, the organosilicon varnish further comprises 0.1-1.0 part of leveling agent, wherein the leveling agent is polyether modified organosilicon.
The leveling agent can be used for preventing defects such as shrinkage cavity, orange peel and the like of a varnish layer. When the varnish is coated on the surface of the substrate, two interfaces are formed, namely a substrate-paint film interface and a paint film-air interface, so that the total energy of the system is equal to the sum of the tension of the two interfaces. After the leveling agent is added into the system, if the leveling agent migrates to a paint film-air interface, the total energy of the system=the surface tension of a base material-the surface tension of the paint film+the surface tension of the leveling agent-the surface tension of the air, and the total energy of the system is reduced because the surface tension of the leveling agent is less than the surface tension of the paint film, the process can be spontaneously performed, the flatness of a varnish layer is ensured, and the problems of shrinkage cavity and orange peel of the varnish layer are avoided.
The polyether modified organosilicon is a commercial product, and the specific model can be any one of BYK-333, BD-333, BYK-307, BD-3033H and the like.
Specifically, the varnish has a coating thickness of 15 to 30 μm. The varnish layer can improve the glossiness of the surface of the porcelain product with composite decoration, so that the overall glossiness is more uniform, when the coating thickness of the varnish is more than 30 mu m, a large amount of orange peel appears, the overall appearance is affected, and the decoration effect is reduced. When the coating thickness of the varnish is less than 15 μm, the coating is too thin, affecting brightness and luminance effects.
Specifically, the ink frit comprises the following chemical components in percentage by weight: 15-30% SiO 2 、3～6%K 2 O、5～8%Na 2 O、5～20%B 2 O 3 、5～12%Li 2 O and 1-5% ZnO.
SiO in the ink frit 2 The content of (C) is not more than 30%, when SiO 2 Above 30%, reddish brown greenish yellow or dark brown shades may appear, resulting in a color distortion of reddish brown. In addition, znO is also introduced into the ink frit, so that the color development of the low-temperature ink is more vivid, the saturation and the bonding degree are high, but the ZnO content is not too high, and the ZnO content is higher than 5 percent, so that the natural color tone is lightened.
Specifically, the pigment comprises one or more of vanadium yellow, vanadium zirconium blue, red brown, cobalt blue, cobalt black, malachite green and tin antimony ash.
The pigment comprises the above types and the matching combination of the above pigments, and a large number of colors can be prepared through the matching of the above pigments, so as to meet the demands of customers.

the leveling agent is polyether polyester modified organic siloxane;
the auxiliary agent comprises any one or more of polyethylene binder, polypropylene binder and naphthene precipitant.
The low temperature ink dispersant is used to increase and improve the material dispersion properties and to increase the storage stability. Low Wen Moshui defoamer is used to reduce surface tension and prevent foam formation; the leveling agent is used for improving gloss and increasing leveling effect; the auxiliary agent can avoid uneven deposition, thereby avoiding occurrence of coffee rings. Among the auxiliary agents, the binding agent can improve the smoothness and layering of the ink; the anti-settling agent can improve the stability of the ink, and can ensure that the pigment in the ink is permanently and uniformly distributed in a static or dynamic environment without settling.
Optionally, the ceramic matrix comprises one of a ceramic tile and a ceramic tile body. In practical applications, the ceramic matrix may be a ceramic tile, or a tile body with a ceramic surface. The firing temperature of the brick body with the surface subjected to porcelain is 1150-1160 ℃.
Specifically, the porcelain tile comprises the following components in parts by weight:
2 to 5 parts of Jili aluminum sand, 20 to 30 parts of star river sand, 25 to 35 parts of potassium sodium stone powder, 4 to 7 parts of sand sugar bauxite, 5 to 8 parts of bentonite and 10 to 15 parts of waste brick powder.
The firing temperature of the ceramic tile is 1000-1120 ℃. Bentonite is introduced into the formula of the porcelain tile to replace kaolin, so that the optimization of the formula is realized. Although bentonite and kaolin both belong to the class of clay minerals, the two differ significantly. The main component of bentonite is montmorillonite, which belongs to an aluminosilicate, and the ratio of silica to water aluminum is 2:1, namely, a wafer unit formed by combining two silica sheets and a water aluminum sheet is mutually overlapped. Both sides of each crystal layer are respectively provided with O 2- Ions cannot form bonds between crystal layers during superposition, but are connected through bridge oxygen, the connecting force is weak, and the crystal layers are easy to crack, so that the crystal grains of bentonite are smaller than those of kaolinite. The kaolin wafer is bonded by hydrogen bond, so that water molecules and other ions are difficult to soak between the layers and form larger particles, so that the kaolin wafer has weaker adhesiveness and plasticity. Thus, ceramic tileBentonite is introduced to make the viscosity, plasticity, water absorption and suspension better than porcelain tiles containing kaolin.
The invention also provides a preparation method of the composite decorative porcelain product, which is used for preparing the composite decorative porcelain product and comprises the following steps:
preparing a porcelain matrix: the green body of the porcelain matrix is subjected to primary firing to obtain a primary fired porcelain matrix;
preparation low Wen Moshui: mixing all the components of the low-temperature ink according to the proportion, and uniformly stirring to obtain the low-temperature ink;
printing patterns: printing patterns on the surface of the ceramic matrix fired at one time by using low-temperature ink to form a pattern layer, so as to obtain the ceramic matrix with patterns;
and (3) microwave sintering: performing secondary firing on the porcelain matrix with the pattern by adopting a microwave sintering process to obtain a semi-finished product;
coating varnish: and coating varnish on the surface of the semi-finished product to obtain the porcelain product with composite decoration.
In the prior art, the sintering temperature of ceramic products is generally higher than 1160 ℃, and the preparation method adopts a microwave sintering mode for sintering, and has the characteristics of rapid heating, low sintering temperature, material tissue refinement and ceramic material performance improvement. And the sintering range of microwave sintering is wide, the sintering atmosphere in the furnace is complete, and compared with the conventional sintering, the microwave sintering has no temperature difference problem. The chemical composition of the blank is as follows: 60 to 70 percent of SiO 2 、15～20%Al 2 O 3 1 to 3 percent of CaO, 1 to 3 percent of MgO and 4 to 8%K 2 O。

In practical application, the sintering temperature is not too high, the sintering time is not too long, otherwise, the dark color system has the problem of burning loss phenomenon, and the color of the dark color system is distorted. In the normal temperature to 300 ℃ stage in the microwave sintering process, when the temperature rising speed is more than 5 ℃/min, the change of the low-temperature ink layer with small volume is easy to cause cracking due to uneven stress due to the fast blank conversion speed.
