Oily deep functional ink, deep texture wood grain brick and preparation method of deep texture wood grain brick

Abstract

The invention provides oily deep functional ink, a deep texture wood grain brick and a preparation method of the deep texture wood grain brick, and relates to the technical field of preparation of decorative ceramic tiles. The oily deep functional ink comprises the following components in parts by weight: 28-38 parts of high-barium frit; 0-6 parts of a bright frit; 0-8 parts of zinc vanadate; 51-60 parts of an organic solvent; and 3-6 parts of a dispersant. According to the oily deep functional ink provided by the invention, the formation of concave-convex textures can be caused by utilizing the incompatibility between the oily characteristic of the functional ink and the water-based characteristic of the soft and smooth deep glaze, so that a vivid wood grain effect is created on the surface of a brick. According to the texture forming mode based on the material repulsion principle, the stereoscopic impression and the reality sense of the texture are improved, and due to natural forming in the separation process, dependence on additional machining or complex operation in the production process can be reduced.

Description

Technical Field

[0001] The invention relates to the technical field of decorative tile preparation, and in particular to an oily deep-textured functional ink, a deep-textured wood-grain tile and a preparation method thereof. Background Art

[0002] As a widely used building material, ceramic tiles are not only favored for their durability and easy maintenance, but also become an important element of indoor and outdoor decoration for their decorative effects. With the development of technology and the improvement of consumers' aesthetic taste, the design of ceramic tiles has become more and more diversified. Among them, wood-grain ceramic tiles have become a popular choice in the market for their decorative effects that imitate natural wood texture.

[0003] In the prior art, wood-grain tiles provide a warm and natural decorative effect for interior spaces by simulating the texture and color of natural wood. These products usually use advanced printing technology to form realistic wood grain patterns on the surface of the tiles. However, despite the realistic patterns, existing wood-grain tiles often lack the fineness and warmth of real wood in terms of touch. Their surfaces feel relatively rough and lack a well-defined texture effect, which limits their application in the high-end decoration market.

[0004] In addition, the existing surface treatment technology of wood-grain tiles also has limitations. Most products are printed flat and cannot provide a true three-dimensional sense, which makes the tiles significantly different from natural wood in terms of vision and touch. This difference not only affects the authenticity of the decorative effect, but also reduces the beauty and practicality of the product.

[0005] In short, it is mainly reflected in the surface texture and three-dimensional sense of wood grain tiles. The rough surface treatment and the lack of real concave and convex texture effect make the product unable to fully meet the market demand for high-quality and high-simulation decorative tiles. These defects limit the application potential of wood grain tiles in the high-end market and also affect consumers' satisfaction with such products. Therefore, the market urgently needs a tile product that can provide a more realistic wood grain effect to meet the growing demand for high-end decoration.

[0006] In view of this, the present invention is proposed. Summary of the invention

[0033] In a second aspect, the present invention further provides a deep-textured wood-grain brick, comprising a brick body provided with a surface glaze layer, and a texture layer provided on the surface glaze layer;

[0034] The texture layer includes a functional ink layer formed by the oily deep functional ink as described in the above embodiment, and an aqueous smooth deep glaze applied on the functional ink layer, and the texture layer with a deep wood grain texture is formed by the oily deep functional ink and the smooth deep glaze.

[0035] In an optional embodiment, the smooth deep glaze comprises the following components in parts by weight:

[0036] Potassium feldspar 30-37;

[0037] Burnt talc 25-30;

[0038] Quartz 15-25;

[0055] In a third aspect, the present invention further provides a method for preparing a deep-textured wood-grain brick as described in any one of the aforementioned embodiments, comprising:

[0056] The oily deep-cut functional ink and the smooth deep-cut glaze are prepared respectively;

[0057] Apply full polishing glaze to the surface of the brick to form a surface glaze layer;

[0067] Organic solvent 51-60;

[0068] Dispersant 3-6;

[0069] The present invention provides an oily deep functional ink, a deep texture wood grain brick and a preparation method thereof. The oily deep functional ink is a functional ink with hydrophobicity. The oily deep functional ink uses the incompatibility between the oily properties of the oily deep functional ink and the watery properties of the smooth deep glaze. When the smooth deep glaze acts on the deep functional ink, a natural water-oil separation phenomenon will occur. This separation effect directly leads to the formation of a concave and convex texture, thereby creating a realistic wood grain effect on the surface of the brick. This texture formation method based on the principle of material repulsion not only improves the three-dimensional sense and realism of the texture, but also reduces the dependence on additional mechanical processing or complex operations in the production process due to the natural formation of the separation process. This not only reduces production costs, but also improves production efficiency. In addition, this texture formation method based on the natural reaction of materials also helps to improve the durability and stability of the product, because the texture is formed at the material level, rather than through a later additional process.

[0070] In short, this technical solution based on oily deep functional ink, which can interact with hydrophilic smooth deep glaze to form deep texture, provides an innovative way to achieve tiles with deep wood grain texture, which not only enhances the decorative effect of the product, but also improves the practicality and economy of the product.

[0075] Figure 4 This is a schematic diagram of the product surface state of the wood grain brick (conventional wood grain brick) provided in Comparative Example 2 of the present application. DETAILED DESCRIPTION

[0076] The embodiments of the present invention will be described in detail below in conjunction with the examples, but it will be appreciated by those skilled in the art that the following examples are only used to illustrate the present invention and should not be considered as limiting the scope of the present invention. If no specific conditions are specified in the examples, the conditions are carried out according to normal conditions or the conditions recommended by the manufacturer. If the manufacturer of the reagents or instruments used is not specified, they are all conventional products that can be obtained commercially.

[0077] In an embodiment of the present application, an oily deep functional ink is provided, comprising the following components by weight:

[0078] High barium frit 28~38;

[0079] Bright frit 0~6;

[0080] Zinc vanadate 0~8;

[0081] Organic solvent 51-60;

[0082] Dispersant 3-6;

[0083] Oil-based deep functional ink is an innovative decorative material that can be accurately applied to the glaze layer of the brick blank through inkjet printing technology to form a realistic wood grain pattern decorative layer. This ink has a hydrophobic property, which enables it to clearly present the wood grain pattern on the glaze layer while ensuring the durability and stability of the pattern.

[0084] During the application process, the hydrophobic properties of the oily deep functional ink interact with the hydrophilic properties of the surface glaze, producing a unique incompatibility phenomenon, namely the water-oil separation effect. Specifically, because the oily properties of the ink and the watery properties of the glaze repel each other, when the glaze layer is covered on the ink layer, the two do not mix with each other, but form a clear separation at their contact interface. This separation effect causes the pattern part of the glaze layer on the ink layer to form a concave and convex texture, effectively simulating the texture effect of natural wood, bringing a more natural and three-dimensional decorative effect to the surface of the brick.

[0085] Further, the organic solvent is ethyl acetate;

[0086] Furthermore, the dispersant is a condensate of fatty alcohol and ethylene oxide.

[0087] Furthermore, the high-barium frit is a frit formed by mixing SiO2, Al2O3, CaO, K2O, Na2O, BaO, ZnO and SrO.

[0088] Furthermore, the weight proportion of BaO in the high-barium frit is 16% to 20%.

[0089] Furthermore, the bright frit includes the following components in parts by weight:

[0090] SiO2 40~50;

[0091] Al2O3 15~25;

[0092] Na2O 10~20;

[0093] K2O 5~15;

[0094] CaO 5-10;

[0095] MgO 1~5.

[0096] Furthermore, the bright frit includes the following components in parts by weight:

[0097] SiO2 45;

[0098] Al2O3 20;

[0099] Na2O 15;

[0100] K2O 10;

[0101] CaO 8;

[0102] MgO 2.

[0103] In an embodiment of the present application, a deep-textured wood-grain brick is further provided, comprising a brick body provided with a surface glaze layer, and a texture layer provided on the surface glaze layer;

[0104] The texture layer includes a functional ink layer formed by the oily deep functional ink as described above, and an aqueous smooth deep glaze applied on the functional ink layer, and the texture layer with a deep wood grain texture is formed by the oily deep functional ink and the smooth deep glaze.

[0105] As mentioned above, the brick body is the basic structure of the wood grain brick, and its surface is covered with a layer of glaze. This layer of glaze not only provides protection for the brick body, but also provides a smooth foundation for the subsequent formation of the texture layer.

[0106] On top of the glaze layer, building the texture layer is the key step to achieve a deep wood grain texture. The texture layer consists of two parts: one is the oil-based functional ink layer, and the other is the water-based smooth deep glaze.

[0107] The functional ink layer is applied to the glaze layer by inkjet printing technology to form a wood grain pattern decorative layer. This ink is oily and can form a clear wood grain pattern on the glaze layer, and has good durability and stability.

[0108] On top of the functional ink layer, a layer of water-based smooth deep glaze is applied. This glaze, due to its water-based properties, is incompatible with the oily ink layer below, i.e., water-oil separation. Due to the incompatibility between the oiliness of the deep functional ink and the wateriness of the smooth deep glaze, when the glaze layer is covered on the ink layer, the two do not mix, but form a separation at the interface. This separation causes the glaze layer to form an uneven effect on the pattern of the ink layer, thereby simulating the texture of natural wood.

[0109] By adjusting the pattern design of the deep functional ink and the formula of the smooth deep glaze, the shape and depth of the final wood grain texture can be precisely controlled. This adjustment makes the concave and convex effect of the texture layer more delicate and realistic, and can reach a texture depth of 2mm, which is far beyond the texture depth of other products on the market (the texture depth of similar craft wood grain bricks on the market, or wood grain bricks prepared by traditional preparation technology, is less than 1mm).

[0110] After the texture layer is formed, the brick will enter the firing process. During the high-temperature firing process, the glaze will solidify and the texture will be permanently fixed to the surface of the brick. This step ensures the durability and wear resistance of the texture, allowing the wood grain brick to maintain its beautiful appearance in long-term use.

[0111] In short, this technical solution has realized a novel method of forming wood grain brick texture by cleverly utilizing the difference in the physical properties of the materials. This method not only improves the aesthetics and realism of the product, but also enhances the durability and practicality of the product.

[0112] Further, the smooth and deep glaze comprises the following components in parts by weight:

[0113] Potassium feldspar 30-37;

[0114] Burnt talc 25-30;

[0115] Quartz 15-25;

[0116] Kaolin 5-8;

[0117] Calcite 12-16;

[0118] Burn zinc oxide 3-4;

[0119] Barium carbonate 3-4.

[0120] Further, the chemical elements and corresponding weight percentages contained in the smooth and deep glaze are:

[0121] SiO2 52~58;

[0122] Al2O3 16.5~17.5;

[0123] CaO 9.0~10.0;

[0124] MgO 5-6;

[0125] K2O 4.0~5.0;

[0126] Na2O 2.5~3.5;

[0127] Bao 1.0~2.0;

[0128] ZnO 3~4;

[0129] Fe2O3≤0.3;

[0130] TiO2≤0.1;

[0131] IL 12.0~14.0.

[0132] As mentioned above, the smooth deep glaze achieves a significant improvement in glaze performance through the above chemical formula, so that the final product not only has a delicate and smooth glaze surface, but also can show a concave and convex texture close to natural wood grain.

[0133] Through the above formula, the smooth deep glaze can not only provide a delicate and smooth glaze, but also form a concave and convex wood grain texture through the interaction with the deep functional ink. The silicon-aluminum ratio of this glaze is optimized, which helps to improve the performance of the glaze, making the glaze gloss moderate and delicate. At the same time, the introduction of zinc oxide helps to appropriately reduce the firing temperature and improve the color of the glaze, so that the final product has good practicality and durability while maintaining beauty.

[0134] In addition, reference Figure 1 The present application also provides a method for preparing a deep-textured wood-grain brick as described in any of the aforementioned embodiments, comprising:

[0135] Step S1, respectively preparing an oily deep-cut functional ink and a smooth deep-cut glaze;

[0136] The above steps involve mixing and preparing the oily deep functional ink and smooth deep glaze according to a specific formula. The oily deep functional ink contains an oily component, while the smooth deep glaze is a water-based component. Through precise formulation, it is ensured that the ink and glaze have the correct chemical composition and physical properties, laying the foundation for subsequent texture formation and glaze quality.

[0137] The raw materials can be mixed according to the formula ratio through industrial-grade mixing equipment. During the mixing process, the physical mixing and chemical interaction between the raw materials ensure the uniformity and stability of the ink and glaze.

[0138] Step S2, applying full polishing glaze to the surface of the brick to form a surface glaze layer;

[0139] As mentioned above, a layer of full-polished glaze is evenly applied on the surface of the brick to form a smooth glaze layer, which provides a smooth foundation for the subsequent texture layer and helps to improve the aesthetics and surface quality of the final product. The uniformity and consistency of the glaze layer can be ensured by automated glazing equipment such as glaze line pouring or glaze spraying machine.

[0140] During the glazing process, the uniform distribution and initial solidification of the glaze on the brick surface provide the basis for the subsequent texture formation.

[0141] Step S3, based on the oily deep functional ink, inkjet printing is performed on the surface of the glaze layer to form a functional ink layer consisting of a wood grain pattern and the oily deep functional ink;

[0142] As mentioned above, the wood grain pattern and the oily deep functional ink layer are formed on the glaze layer by inkjet printing technology using deep functional ink. This step achieves the precise transfer of the wood grain pattern and lays the foundation for the formation of deep wood grain texture. High-precision inkjet printing equipment is used to ensure the clarity and consistency of the pattern.

[0143] During the inkjet process, the ink is evenly distributed and initially solidified on the top glaze layer, forming a clear wood grain pattern.

[0144] Step S4, applying a smooth deep glaze on the functional ink layer to form the texture layer with a deep wood grain texture;

[0145] As mentioned above, a smooth deep glaze is applied on the functional ink layer where the wood grain pattern has been printed. This step forms a texture layer with deep wood grain texture through the principle of water-oil separation, which enhances the three-dimensional sense and realism of the product. The uniform distribution of the glaze can be ensured by automated glazing equipment, such as a glaze sprayer or roller coating equipment.

[0146] During the glazing process, the oily nature of the oily deep-working ink and the water-based nature of the smooth deep-working glaze are incompatible, naturally forming a concave and convex texture.

[0147] Step S5, firing treatment, to obtain the deep texture wood grain brick.

[0148] As mentioned above, the bricks coated with the texture layer are placed in a kiln for high-temperature firing to solidify the texture layer and complete the final shape of the tile. The firing process not only solidifies the texture layer, but also improves the durability and weather resistance of the product, ensuring the long-term stability and aesthetics of the product. Specifically, high-temperature firing can be performed in an industrial kiln to accurately control the firing temperature and time.

[0149] During the firing process, the chemical components of the glaze and the ink react at high temperatures to form a stable texture structure. Throughout the preparation process, the synergistic effects of each step achieve a profound wood grain texture and a delicate and smooth glaze surface, enhancing the aesthetic appeal and market competitiveness of the product.

[0150] In an alternative embodiment, the raw materials of the oil-based deep-functional ink and the smooth deep glaze are both mixed through a ball mill;

[0151] Among the raw materials of the smooth deep glaze, at least 99% of the particle sizes are not larger than the pore size of a 325-mesh sieve.

[0152] Furthermore, the raw materials of the oil-based deep-functional ink and the smooth deep glaze are both mixed through a ball mill;

[0153] Among the raw materials of the smooth deep glaze, at least 99% of the particle sizes are not larger than the pore size of a 325-mesh sieve.

[0154] The present invention will be further illustrated by specific embodiments below. However, it should be understood that these embodiments are only for more detailed illustration and should not be construed as limiting the present invention in any form.

[0201] Conventional wood grain tiles are flat and have no bumpy wood grain texture, so they do not use functional ink formulas. Instead, they use ordinary color inks, including: Myris 112120-4 blue ink, Itajia 5115 brown ink, Myris 342120 beige ink and Itajia 6118 black ink.

[0202] Horizontal comparison experiment:

[0203] The decorative tiles prepared in Examples 1 to 3 and the comparative example were compared.

[0206] analyze:

[0207] (1) Reference Figures 2 to 4 , and the data in Table 7, Example 1 ( Figure 2 )~3 The deep texture wood-grain bricks prepared have a smooth and delicate touch and the wood texture is smooth with a depth of 2mm; Comparative Example 1 ( Figure 3 ) Using similar technology, the wood-grain bricks produced have a rough touch and the wood texture is not smooth enough with a depth of only ≤1mm; Comparative Example 2 ( Figure 4 ), the conventional wood grain bricks prepared have no concave-convex wood texture on the plane.

[0208] Examples 1, 2 and 3 all exhibit a concave-convex texture with the finest part being 0.3 mm, wherein the finest part of the texture of Example 3 is 0.4 mm, which indicates that the technical solutions adopted in these examples can produce a very delicate texture effect.

[0209] The finest part of the texture of Comparative Example 1 is greater than 1 mm, which means that its texture is not fine enough to simulate the fine texture of natural wood. Comparative Example 2 is a conventional wood-grain tile with no texture, which indicates that its decorative effect may be relatively simple and lacks three-dimensionality.

[0210] (2) The texture depth of Examples 1, 2 and 3 is 2 mm, which is a relatively deep texture that can provide a more realistic wood grain effect and enhance the three-dimensional sense and visual appeal of the tile.

[0211] The texture depth of Comparative Example 1 is less than 1 mm, which cannot provide sufficient three-dimensional effect and affects the decorative effect.

[0212] Comparative Example 2 has no texture depth, indicating that its surface may be completely smooth without any concave-convex texture, which may not satisfy the pursuit of natural wood grain texture in terms of decorative effect.

[0213] In summary, according to the comparison results in Table 7, the technical solutions adopted in Examples 1, 2 and 3 are significantly better than those in Comparative Examples 1 and 2. The deep-grained wood-grained tiles prepared in the examples are superior to the comparative samples in terms of texture fineness and depth, and can better simulate the texture effect of natural wood, providing a richer and more realistic decorative effect. This shows that the technical solution of the present invention can effectively create tiles with deep wood-grain textures, meeting the market demand for high-quality, high-simulation decorative tiles. Therefore, the technical solution of the present invention has significant advantages in improving the aesthetics and market competitiveness of the product.
