Description

Technical Field

[0001] This invention relates to the field of ceramic technology, specifically to a wear-resistant, antique-style gold-thread brocade glaze ceramic product and its preparation method. Background Technology

[0002] Antique-style gold-thread brocade glaze ceramics are precious works of art that blend traditional craftsmanship and modern ceramic techniques. They are made by applying a brocade-patterned glaze based on natural minerals to the surface of the ceramic body, followed by high-temperature reduction firing. These products retain the jade-like texture and crackle-like patterns of the layered brocade glaze found in ancient imperial kilns, while the addition of a metallic luster enhances the three-dimensionality and visual depth of the patterns, creating a magnificent, shimmering effect under light and shadow. In recent years, with the rise of the Neo-Chinese design style, these products have been widely used in high-end architectural interiors, art collections, and luxury tableware, becoming a material carrier for the inheritance of Eastern aesthetics.

[0003] However, existing antique-style gold-thread brocade glaze ceramics have gradually revealed limitations in durability during actual use, particularly in the wear resistance of the glaze, which urgently needs improvement. Due to the difference in thermal expansion coefficients between the precious metal material and the underlying glaze, as well as insufficient interfacial bonding strength, frequent wiping or contact friction easily leads to microscopic peeling at the edges of the gold threads. This not only causes defects such as broken lines and blurring of the gold patterns, but also exposes the underlying glaze due to the shedding of metal particles, creating visual color differences. This structural weakness is particularly pronounced in high-frequency use scenarios such as tea sets and tabletops, affecting the long-term preservation of the work's integrity and aesthetics, and also restricting its further expansion in the market for practical high-end handicrafts. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a wear-resistant, antique-style gold-thread brocade glaze ceramic product and its preparation method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A wear-resistant, antique-style gold-thread brocade glaze ceramic product includes a body and a glaze layer on the surface of the body. The glaze layer is characterized by comprising the following components by weight: 26-30 parts potassium feldspar, 3-10 parts quartz, 15-25 parts kaolin, 15-25 parts calcium carbonate, 3-8 parts calcium phosphate, 3-10 parts zinc oxide, 5-15 parts iron oxide red, and 15-20 parts wear-resistant granules.

[0006] In the technical solution disclosed in this invention, potassium feldspar forms a glassy phase at high temperature, which constitutes the basic framework of the glaze layer. The amount of potassium feldspar can be selected as 26 parts, 27 parts, 28 parts, 29 parts, or 30 parts, but is not limited to the listed values. Other unlisted values ​​within the range are also applicable.

[0007] In the technical solution disclosed in this invention, quartz, as a network forming body, can effectively improve the mechanical strength of the glaze layer. The number of quartz parts can be 3, 4, 5, 6, 7, 8, 9, or 10 parts, but is not limited to the listed values. Other unlisted values ​​within the range are also applicable.

[0008] In the technical solution disclosed in this invention, kaolin provides the necessary plasticity and suspension stability for the glaze, and generates needle-like mullite microcrystals during firing, which play a subtle reinforcing role. The amount of kaolin can be selected as 15 parts, 16 parts, 17 parts, 18 parts, 19 parts, 20 parts, 21 parts, 22 parts, 23 parts, 24 parts, or 25 parts, but is not limited to the listed values. Other unlisted values ​​within the range are also applicable.

[0009] In the technical solution disclosed in this invention, calcium carbonate, as a flux, can adjust the melting temperature range of the glaze and promote the precipitation of tiny crystals in the glaze during cooling. The amount of calcium carbonate can be selected as 15 parts, 16 parts, 17 parts, 18 parts, 19 parts, 20 parts, 21 parts, 22 parts, 23 parts, 24 parts, or 25 parts, but is not limited to the listed values. Other unlisted values ​​within the range are also applicable.

[0010] In the technical solution disclosed in this invention, calcium phosphate can promote liquid phase separation in the glaze melt to form a unique micro-nano-scale phase separation structure. This structure can scatter light of a specific wavelength, enhancing the richness and layering of the color. The amount of calcium phosphate can be 3, 4, 5, 6, 7, or 8 parts, but is not limited to the listed values. Other unlisted values ​​within the range are also applicable.

[0011] In the technical solution disclosed in this invention, zinc oxide can improve the smoothness of the glaze surface and can also serve as an intermediate to promote the color development of other coloring minerals. The amount of zinc oxide can be selected as 3 parts, 4 parts, 5 parts, 6 parts, 7 parts, 8 parts, 9 parts, or 10 parts, but is not limited to the listed values. Other unlisted values ​​within the range are also applicable.

[0012] In the technical solution disclosed in this invention, iron oxide red is used as a coloring raw material. The amount of iron oxide red can be selected as 5 parts, 6 parts, 7 parts, 8 parts, 9 parts, 10 parts, 11 parts, 12 parts, 13 parts, 14 parts, or 15 parts, but is not limited to the listed values. Other unlisted values ​​within the range are also applicable.

[0013] In the technical solution disclosed in this invention, the preparation method of the wear-resistant granules is as follows: The V2O5-Bi2O3-B2O3 system glass is heated and melted to obtain a glass melt. Then, a mesoporous titanium dioxide carrier is immersed in the glass melt, impregnated, cooled, and ground to obtain the wear-resistant granules.

[0014] Specifically, the mass ratio of the V2O5-Bi2O3-B2O3 system glass to mesoporous titanium dioxide is 20-30:5-10, for example, 20:5, 20:8, 20:10, 25:5, 25:8, 25:10, 30:5, 30:8, 30:10, but is not limited to the listed values. Other unlisted values ​​within the range are also applicable.

[0015] Specifically, in the V2O5-Bi2O3-B2O3 series glass, the content of V2O5 is 30-50 mol%, the content of Bi2O3 is 10-20 mol%, and the balance is B2O3.

[0016] Specifically, the impregnation process is as follows: vacuum up to 10-20 Pa and maintain for 1-2 hours, then pressurize to 3-6 MPa and maintain for 3-5 hours.

[0017] In the technical solution disclosed in this invention, the mesoporous titanium dioxide carrier is a nanomaterial with high hardness and a very large specific surface area, making it an extremely efficient light scattering center. This increases the propagation path of light within the glaze layer, allowing color-emitting ions (such as iron in iron oxide red) more opportunities to absorb light of specific wavelengths, thus making the color appear richer and more vibrant, and enhancing color saturation. During the high-temperature stage of glaze sintering, the V2O5-Bi2O3-B2O3 glass softens and melts again, flowing out from the surface and pores of the mesoporous titanium dioxide carrier and diffusing into the surrounding glaze substrate. V2O5 interacts with zinc oxide and iron oxide red, forming varying shades of brownish-yellow in localized areas, making the color appear fuller and more lustrous. Bi2O5... The addition of O3 increases the refractive index of the glass, creating a larger refractive index difference between the high-refractive-index glass phase and the base glaze, thereby enhancing the light scattering effect and further improving color saturation. This invention loads V2O5-Bi2O3-B2O3 system glass onto a mesoporous titanium dioxide carrier, avoiding the problems of uneven dispersion of glass powder in the glaze slurry, easy generation of bubbles at the interface, or glaze de-opaqueness and dull color, compared to directly adding it as ordinary glass powder to the glaze. Furthermore, the glass in the wear-resistant granules will melt a second time and partially flow out during sintering. The flowed glass forms a strong chemical bond with the surrounding glaze, like an anchor, firmly fixing the hard titanium dioxide core in the glaze layer, preventing the particles from falling off, and thus enhancing the wear resistance.

[0018] The present invention also provides a method for preparing the above-mentioned wear-resistant antique gold-thread brocade glaze ceramic products, comprising the following steps: mixing all the raw materials of the glaze with water evenly, ball milling, sieving, and adding water to prepare a glaze slurry; applying the glaze slurry to the surface of the body, and after drying and reduction calcination, forming a glaze layer on the surface of the body, thereby obtaining the wear-resistant antique gold-thread brocade glaze ceramic products.

[0019] In the technical solution disclosed in this invention, the concentration of the glaze slurry is 35-55 Baume degrees.

[0020] In the technical solution disclosed in this invention, the thickness of the glaze layer is 40-60μm.

[0021] In the technical solution disclosed in this invention, the specific process of reduction calcination is as follows: the temperature is raised to 700-800℃ at a rate of 3-5℃ / min; then, a reducing atmosphere of CO 5-8% and O2 <1% is maintained, and the temperature is raised to 1200-1280℃ at a rate of 1-2℃ / min, and held for 2-3 hours.

[0022] Compared with the prior art, the present invention has the following beneficial effects: (1) The wear-resistant granules provided by this invention, the mesoporous titanium dioxide carrier is a nanomaterial with high hardness and a very large specific surface area, making it an extremely efficient light scattering center, increasing the propagation path of light in the glaze layer, and giving color-emitting ions (such as iron elements in iron red) more opportunities to absorb light of specific wavelengths, thus making the color look thicker and brighter, and improving the color saturation; during the high-temperature stage of glaze sintering, the V2O5-Bi2O3-B2O3 glass will soften and melt again, flowing out from the surface and pores of the mesoporous titanium dioxide carrier and diffusing into the surrounding glaze substrate. V2O5 interacts with zinc oxide and iron red to form brownish-yellow tones of varying shades in the local area, making the color look fuller and more lustrous. The addition of Bi2O3 increases the refractive index of the glass, making the high refractive index glass phase and the base glaze form a larger refractive index difference, thereby enhancing the light scattering effect and further enhancing the color saturation.

[0023] (2) By loading V2O5-Bi2O3-B2O3 series glass onto a mesoporous titanium dioxide carrier, this invention avoids the problem of uneven dispersion of glass powder in the glaze slurry, which can easily generate bubbles at the interface or cause the glaze to lose transparency and result in a dull color, compared to directly adding it as ordinary glass powder to the glaze. Furthermore, the glass in the wear-resistant granules will melt a second time and partially flow out during sintering. The flowing glass forms a strong chemical bond with the surrounding glaze, which firmly fixes the hard titanium dioxide core in the glaze layer like an anchor, preventing the particles from falling off and thus enhancing the wear resistance.

[0024] (3) Through the synergistic effect of multiple components in the glaze, this invention overcomes the problem of easy detachment of the reinforcing phase in traditional brocade glaze while maintaining the unique artistic texture of antique brocade glaze, so that the glaze surface can obtain excellent overall wear resistance. The resulting product achieves an effective unity of antique artistic aesthetics and long service life, and is especially suitable for high-end furnishings and daily use occasions with high requirements for surface durability.
