Description

Technical Field

[0001] The invention relates to the technical field of ceramic tile preparation, in particular to a ceramic tile with multi-faceted effects and a manufacturing method thereof. Background Art

[0002] The existing ceramic tile products usually have a decorative effect of one surface per tile (i.e., only one surface effect on one tile), which lacks diversity and three-dimensionality. In order to meet the market demand for diversified decorative effects, a decorative technology that can achieve different surface effects on the same ceramic tile is particularly necessary.

[0003] It is known that glossy ink or semi-polishing can also be used to create a glossy contrast effect on the brick surface, but glossy ink can only create a line-like glossy effect, and the glossy area cannot exist in a large area, such as Figure 1 As shown in the figure, the bright and matte contrast formed by the semi-polished type is formed by polishing the protruding parts of the brick surface, so the bright and matte areas can only be adjusted by the surface height, and the scope of application is relatively narrow, such as Figure 2 shown.

[0004] In view of this, a ceramic tile with a multi-faceted effect that is not limited by the surface morphology of the ceramic tile and whose area and shape can be arbitrarily set according to pattern requirements is particularly necessary. Summary of the invention

It should be understood that the following drawings only show certain embodiments of the present invention and therefore should not be regarded as limiting the scope.

[0032] Figure 3 This is a rendering of the ceramic tile prepared in Example 1. DETAILED DESCRIPTION

[0033] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be described clearly and completely below. If the specific conditions are not specified in the embodiments, they are carried out according to conventional conditions or 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 purchased commercially.

[0034] An embodiment of the present invention provides a ceramic tile with multi-faceted effects, including a substrate and a matte area and a glossy area arranged on the substrate, the matte area including a high-temperature surface glaze layer and a matte protective glaze ink layer formed sequentially on the substrate; the glossy area including a high-temperature surface glaze layer, a low-temperature surface glaze layer and a glossy protective glaze ink layer formed sequentially on the substrate.

[0035] The ceramic tile with multi-faceted effects provided in the embodiment of the present application first forms a high-temperature glaze layer on the substrate, and for the matte area, a matte protective glaze ink layer is formed on the high-temperature glaze layer; for the glossy area, a low-temperature glaze layer is formed on the high-temperature glaze layer, and then a bright protective glaze ink is formed on the low-temperature glaze layer. Through the mutual superposition and action of the high-temperature glaze, the low-temperature glaze and the high-temperature glaze layer, and the low-temperature glaze layer, the gloss of the matte area is lower, and the gloss of the glossy area is higher, which is more conducive to improving the gloss difference between the matte area and the glossy area.

[0036] At the same time, the patterns of the matte and glossy areas, the corresponding areas, and the concave-convex shapes of the ceramic tile surface in the embodiments of the present application will not affect the patterns of the matte and glossy areas, so that the effects of the ceramic tiles can be designed according to the needs of the creator with less external restrictions.

[0037] In an optional embodiment, a zirconium white ink layer is further provided between the high-temperature surface glaze layer of the matte area and the matte protective glaze ink layer; zirconium white ink is also called white ink or surface glaze ink. The presence of the zirconium white ink layer can further reduce the glossiness of the matte area and increase the difference in glossiness between the matte area and the bright area.

[0038] In an optional embodiment, a dry particle layer is also provided on the surface of the ceramic tile, and dry particles can be applied at a preset position on the surface of the ceramic tile to enhance the three-dimensional effect of the surface of the ceramic tile and increase the aesthetics and three-dimensional effect of the product; specifically, the material of the dry particle layer can be selected according to the required glossiness.

[0039] In an optional embodiment, the glaze amount of the high-temperature surface glaze layer is 250 to 400 g / m2, and the glaze amount of the low-temperature surface glaze is 200 to 400 g / m2; since two layers of surface glaze are implemented, due to the difference in thickness of the surface glaze layers, the pattern formed on the low-temperature surface glaze will be more prominent as a whole than the pattern of the high-temperature surface glaze layer, so that the entire brick surface has a three-dimensional effect of different levels.

[0040] In an optional embodiment, it also includes a soft light area, which includes a high-temperature glaze layer and a soft light layer formed on a substrate, and the soft light layer includes at least one of a low-temperature glaze layer, a zirconium white ink layer and a soft light protective glaze layer, and the soft light protective glaze layer is obtained by mixing and firing a glossy protective glaze ink and a matte protective glaze ink.

[0041] The glossiness of the soft light area can be between the bright light area and the matte light area. The specific structure of the soft light area can be set as needed. For example, the soft light area can include a high-temperature glaze layer, a low-temperature glaze layer and a matte protective glaze ink layer, or a high-temperature glaze layer and a bright protective glaze ink layer.

[0042] The present invention also provides a method for manufacturing the ceramic tile with multi-faceted effects as described in the above embodiment, comprising:

[0043] According to the preset effect of the ceramic tile, a high-temperature surface glaze layer, a low-temperature surface glaze layer, a zirconium white ink layer and a protective glaze ink layer are sequentially formed on the ceramic tile substrate, and then fired to obtain the ceramic tile with multi-faceted effects, wherein the protective glaze ink layer includes a matte protective glaze ink layer and a glossy protective glaze ink layer.

[0044] It should be noted that in the implementation mode of the present application, the positions of the high-temperature glaze layer, the low-temperature glaze layer, the zirconium white ink layer and the protective glaze ink layer need to be determined according to the preset effect of the ceramic tile. Normally, a layer of high-temperature glaze needs to be applied to the entire plate on the substrate, but the low-temperature glaze layer and the zirconium white ink layer are not required for the entire plate.

[0045] Specifically, a screen, roller and inkjet machine can be used to position print or inkjet ceramic tiles to form a low-temperature glaze layer; an inkjet machine can be used to position print zirconium white ink in the required area according to the pattern design to form a zirconium white ink layer; the brick blank can be inkjet decorated according to the design, and then matte protective glaze ink and glossy protective glaze ink can be applied to the high-temperature glaze, low-temperature glaze or zirconium white ink respectively according to the effect design.

[0046] In an optional embodiment, after applying dry particles on the protective glaze ink layer and removing excess dry particles, firing is performed, and the presence or absence of the dry particle layer and the type of dry particles can be selected as needed.

[0047] In an optional embodiment, the initial melting temperature of the high temperature glaze is 1000-1100°C, for example, 1000, 1020, 1040, 1060, 1080, 1100°C, and the firing temperature is 1150-1250°C, for example, 1150, 1170, 1190, 1210, 1230, 1250°C.

[0048] In an optional embodiment, the initial melting temperature of the low-temperature glaze is 900-1000°C, for example, 900, 920, 940, 960, 980, 1000°C, and the firing temperature is 1120-1220°C, for example, 1120, 1140, 1160, 1180, 1200, 1220°C.

[0049] The combination of high-temperature glaze and low-temperature glaze has a key influence on the performance of ceramic tiles. The initial melting temperature, firing temperature, etc. of the two need to be coordinated with each other, otherwise it will affect the service life of the ceramic tiles. In severe cases, peeling may occur between the high-temperature glaze layer and the low-temperature glaze layer after firing.

[0050] In an optional embodiment, the high temperature glaze comprises by weight: SiO 2 55-60 parts by weight, Al 2 O3 31-35 parts by weight, Fe 2 O 3 ≤0.3 parts by weight, TiO 2 ≤0.4 parts by weight, CaO≤0.8 parts by weight, MgO≤1.5 parts by weight, K 2 O 1-3 parts by weight, Na 2 O 2.5-4.5 parts by weight, ZrO 2 ≤0.5 parts by weight and ZnO≤1 parts by weight, and IL≤3.5%;

[0056] Among them, zirconium dioxide can improve the opacity and applicable temperature range of the ink; low-temperature high-boron frit can increase the storage stability and applicable temperature range of the ink; dispersant can help pigment particles to be evenly dispersed in the solvent to prevent precipitation and agglomeration; ester compounds can be used as part of the solvent to help adjust the viscosity and surface tension of the ink; the solvent is usually an aqueous or oily solvent used to dilute and dissolve other ingredients.

[0057] The zirconium white ink of this formula is used in this application, which can not only expand the difference in gloss between the bright area and the matte area, but also can be well combined with the glaze and ink on the upper and lower sides thereof, which is beneficial to prolonging the service life of the product.

[0060] The matte protective glaze ink of this formula is used in this application, which can not only keep the matte area at a lower gloss, but also can combine the adjacent layers of ink or glaze well, which is beneficial to improve the service life of the product.

[0061] In an optional embodiment, the gloss protective glaze ink comprises, by weight: 2 to 10 parts by weight of resin, 30 to 60 parts by weight of solvent, 30 to 55 parts by weight of gloss glaze powder, 5 to 10 parts by weight of hyperdispersant, and 0.1 to 3.5 parts by weight of additive;

[0064] In an optional embodiment, the firing temperature is 1150-1200°C, for example, 1150, 1155, 1160, 1165, 1170, 1175, 1180, 1185, 1190, 1195, 1200°C, and the firing time is 40-70 min, for example, 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70 min.

[0065] Firing under this condition is beneficial to improving the bonding strength between the layers and improving the life and stability of the product.

[0066] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0067] Example 1

[0068] This embodiment provides a method for manufacturing a ceramic tile with multi-faceted effects, wherein the ceramic tile includes a matte area and a bright area, and specifically includes the following steps:

[0069] First, pour high-temperature glaze on the ceramic tile substrate, wherein the high-temperature glaze comprises, by weight, 9 parts by weight of washed soil, 5 parts by weight of burnt soil, 24 parts by weight of alumina, 14 parts by weight of nepheline, 7 parts by weight of quartz, 37 parts by weight of albite and 4 parts by weight of talc;

[0070] A low-temperature glaze is poured on the high-temperature glaze in the bright area. The low-temperature glaze is composed of SiO 2 52 parts by weight, Al 2 O 3 19 parts by weight, Fe 2 O 3 0.2 parts by weight, TiO 2 0.2 parts by weight, CaO 6 parts by weight, MgO 3 parts by weight, K 2 O 4 parts by weight, Na 2 O 2 parts by weight, ZrO 2 0.3 parts by weight and 3 parts by weight of ZnO,

[0071] Using an inkjet printer to print zirconium white ink on the matte area, the zirconium white ink consists of 35 parts by weight of zirconium dioxide, 6 parts by weight of a low-temperature high-boron frit with a melting temperature of less than 1000° C., 9 parts by weight of a dispersant, 18 parts by weight of an ester compound, 30 parts by weight of a solvent, and 0.9 parts by weight of an organic pigment dye;

[0072] Matte protective glaze ink is sprayed on the matte area, and glossy protective glaze ink is sprayed on the remaining glossy areas; the matte protective glaze ink is composed of 45 parts by weight of solvent, 40 parts by weight of matte powder glaze, 8 parts by weight of super dispersant and 2 parts by weight of additives; wherein the main components of the matte powder glaze are 6 parts by weight of albite, 6 parts by weight of wollastonite, 3 parts by weight of limestone, 3 parts by weight of calcined zinc oxide, 2 parts by weight of quartz, 12 parts by weight of corundum and 13 parts by weight of high calcium zinc frit; the glossy protective glaze ink is composed of 6 parts by weight of resin, 45 parts by weight of solvent, 45 parts by weight of glossy glaze powder, 8 parts by weight of super dispersant and 2 parts by weight of additives; wherein the glossy glaze powder includes, by weight: SiO 2 62 parts by weight, Al 2 O 3 6 parts by weight, K 2 O4 parts by weight, CaO 18 parts by weight and ZnO 10 parts by weight;

[0073] The firing temperature is 1170° C. and the firing time is 45 min to obtain the ceramic tile with multi-faceted effect, wherein the glaze amount of the high-temperature surface glaze layer is 320 g / m2 and the glaze amount of the low-temperature surface glaze layer is 200 g / m2. Figure 3 shown.

[0074] Embodiment 2:

[0075] The main difference from Example 1 is that before firing, glue is sprayed on a preset area on the surface of the ceramic tile and matte dry particles are applied. After absorbing excess dry particles, matte protective glaze ink is sprayed on the matte area, and glossy protective glaze ink is sprayed on the remaining glossy areas.

[0076] Embodiment 3:

[0077] The main difference from Example 1 is that it also includes a soft light area. The main difference between the soft light area and the bright light area in Example 1 is that the corresponding protective glaze ink is a mixture of the matte protective glaze ink and the bright protective glaze ink used in Example 1 in a volume ratio of 1:1.

[0078] Comparative Example 1

[0079] The main difference from Example 1 is that the high-temperature glaze consists of 9 parts by weight of washed clay, 5 parts by weight of burned clay, 20 parts by weight of alumina, 18 parts by weight of nepheline, 8 parts by weight of quartz, 36 parts by weight of albite and 4 parts by weight of talc.

[0080] In this comparative example, since the high-temperature glaze and the low-temperature glaze cannot be well matched, the low-temperature glaze partially cracks after firing.

[0081] Comparative Example 2

[0082] The main difference from Example 1 is that the low-temperature glaze is composed, by weight, of 9 parts by weight of washed clay, 12 parts by weight of burned clay, 4 parts by weight of quartz, 40 parts by weight of potassium feldspar, 3 parts by weight of talc, 7 parts by weight of limestone, 8 parts by weight of dolomite, 8 parts by weight of barium oxide, 4 parts by weight of zinc oxide, and 5 parts by weight of low-temperature frit.

[0083] In this comparative example, since the glossiness of the low-temperature glaze is relatively low, the overall bright and matte contrast effect of the glaze is not obvious, and the effect of a large gloss difference is not achieved.

[0084] Comparative Example 3

[0085] The main difference from Example 1 is that the matte area is sprayed with glossy protective glaze ink, and the remaining glossy areas are sprayed with matte protective glaze ink.

[0086] The glossiness of the matte area and the bright area in the above examples and comparative examples and the thermal stability of the obtained ceramic tiles were tested, and the results are shown in Table 1.

[0087] The glossiness was measured by a gloss meter, and the thermal shock resistance was measured by 10 cycles between 15° and 145° in accordance with Appendix Q of GB / T 4100-2015.
