Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of architectural ceramics, and particularly relates to a jade-imitating ceramic tile with a three-dimensional and sparkling effect and a preparation method thereof. BACKGROUND

[0002] The jade-imitating ceramic tile is a ceramic product with a natural jade texture, and its design concept originates from the beauty and texture of natural jade. With the continuous improvement of people's pursuit of life quality, the jade-imitating ceramic tile is favored by the market due to its unique aesthetic effect and excellent physical properties.

[0003] At present, the jade-imitating ceramic tile is mostly prepared by adjusting the composition of glaze to make the glaze surface have similar luster, texture, and soft touch to natural jade. However, these ceramic tiles mostly only imitate the characteristics and touch of the surface of jade, and the performance effect of details such as ice cracks, water lines, and crystal lines in jade is not good. SUMMARY

[0004] The present application aims to at least solve one of the technical problems existing in the prior art. To this end, the present application proposes a jade-imitating ceramic tile with a three-dimensional and sparkling effect and a preparation method thereof. The surface of the ceramic tile is soft and delicate, and has no obvious glaze crystal spots. At the same time, the bright light effect is integrated from the glaze layer to the surface of the ceramic tile, so that it has a certain three-dimensional and level sense, and has a visual effect of sparkling and light metal luster, perfectly presenting the details of the high-brightness luster such as ice cracks, water lines, and crystal lines in jade.

[0005] To solve the above technical problems, the first aspect of the present application provides a jade-imitating ceramic tile, which comprises, from bottom to top, a body, a bottom glaze layer, a soft light transparent glaze layer, a color ink layer, a bright light ink layer, and a matte transparent dry particle layer.

[0006] The soft light transparent glaze layer is fired from a soft light transparent glaze, and the chemical composition of the soft light transparent glaze comprises, in terms of percentage by weight, Al2O3 12-15%, SiO2 42-48%, CaO 5-8%, MgO 4-8%, K2O 2-5%, Na2O 2-5%, BaO 6-9%, ZnO 3-5%, and SrO 2-4%.

[0007] Specifically, the present application sets a layer of soft light transparent glaze between the base glaze layer and the color ink layer, obtains jade-like soft luster and warm texture through the soft light transparent glaze, and prints the color ink and bright light ink on the surface of the soft light transparent glaze by using the digital printing technology, forms a special bright light visual effect with stereoscopic and hierarchical sense, and covers the matte transparent dry particles to blend the bright light into the matte transparent dry particles, eliminates the crystal spots of the soft light transparent glaze, and the luster of the bright light ink is shown through the gaps of the surface dry particles, so that a high-fidelity jade stone effect with high transparency, hierarchical sense, stereoscopic sense and flash sense and a certain light metal luster is obtained.

[0008] When light shines on jade, part of the light is reflected back, which is the luster of the jade that people see. Another part of the light enters the interior of the jade, and due to the existence of ice cracks in the interior of the jade, the light is refracted when passing through the ice cracks, that is, the propagation direction of the light changes. These refracted light will be reflected and refracted in the interior of the jade, and finally, it will pass out of the surface of the jade again. Due to the existence of ice cracks, the propagation path of the light in the interior of the jade becomes more complex, which is the reason why the jade has more details and hierarchical sense.

[0009] The present application extracts the high-brightness part of the ice cracks in the jade design, designs it into the effect net of the bright light ink channel, and prints it on the soft light transparent glaze layer by using the ceramic digital printing equipment. After the bright light ink is fired at high temperature, the high-brightness texture is formed on the soft light transparent glaze. The light can be reflected through the high-brightness texture part, or it can enter the soft light transparent glaze layer to be refracted and scattered, forming a unique optical effect. Specifically, when the bright light ink is covered on the soft light transparent glaze, a series of optical phenomena will occur. On the one hand, the surface of the bright light ink and the soft light transparent glaze will reflect light. When the light shines on the surface, part of the light will be reflected back, forming bright luster. At the same time, due to the difference in refractive index between the bright light ink layer and the soft light transparent glaze layer, the light will be refracted when passing through the bright light ink layer and the soft light transparent glaze layer, so that the propagation direction of the light changes, thereby affecting the path and intensity distribution of the light. Therefore, when the bright light ink is applied on the soft light transparent glaze, the light can pass through the soft light transparent glaze and be refracted and reflected in the base glaze layer, thereby producing stereoscopic and hierarchical sense. On the other hand, a certain thickness of the soft light transparent glaze can provide more opportunities for refraction and reflection, so that the propagation of the light becomes more complex, enhancing the performance of the stereoscopic sense. Therefore, the light can enter the soft light transparent glaze layer and be reflected and scattered in the interior of the glaze layer, thereby producing stereoscopic, hierarchical and transparent sense.

[0010] Meanwhile, the soft light transparent glaze has high content of SiO2, which is beneficial to the high light effect of the glass phase formed by the bright ink and the glaze; and has high content of alkaline earth metal oxides (MgO, CaO) and alkali metal oxides (K2O, Na2O), so as to improve the high temperature fluidity of the glaze, and make the glaze effect after firing more delicate and smooth.

[0011] In some embodiments of the present application, the raw material components of the soft light transparent glaze include, by weight fraction, 28-35 parts of potassium feldspar, 10-20 parts of sodium feldspar, 5-10 parts of washed soil, 0-5 parts of calcined kaolin, 0-4 parts of aluminum oxide, 2-5 parts of quartz, 1-5 parts of wollastonite, 3-8 parts of calcined talc, 15-20 parts of dolomite, 1-5 parts of strontium carbonate, 5-10 parts of barium carbonate, and 2-5 parts of calcined zinc oxide.

[0012] In some embodiments of the present application, the raw material components of the base glaze layer include, by weight fraction, 40-50 parts of potassium feldspar, 0-5 parts of sodium feldspar, 5-15 parts of nepheline, 5-10 parts of washed soil, 10-15 parts of quartz, 10-20 parts of aluminum oxide, and 3-8 parts of wollastonite.

[0013] Specifically, the base glaze has too low initial melting temperature, and the pores of the glaze surface are closed too early, so that the gas generated in the body cannot be completely discharged, and the glaze layer is lifted up during the continuous discharging process, resulting in defects similar to the rash. The base glaze layer of the present application uses potassium feldspar as the main flux raw material, which has a wide firing range and a high initial melting temperature. The high initial melting temperature (1150-1200℃) of potassium feldspar can completely discharge the gas in the body, thereby reducing the generation of rash on the glaze surface and further improving the glaze effect of the imitation jade ceramic tile.

[0014] In some embodiments of the present application, the preparation raw material of the matte transparent dry particle layer is a matte transparent dry particle suspension, and the matte transparent dry particle suspension includes matte transparent dry particles and a suspending agent in a mass ratio of 1:(1.5-2.5).

[0015] Specifically, the matte transparent dry particles are covered on the soft light transparent glaze and the bright ink, which can effectively reduce the gloss of the soft light transparent glaze, eliminate the crystal spots on the soft light transparent glaze, and form a greater contrast in gloss between the glaze surface printed with bright ink and other positions. Meanwhile, the matte transparent dry particles can better protect the color ink layer and the bright ink layer, and improve the wear resistance of the ceramic tile surface. Moreover, after high-temperature firing, the high-brightness parts formed by the bright ink can also penetrate the matte transparent dry particles, showing a bright light effect.

[0016] In some embodiments of the present application, the chemical composition of the matte transparent dry particles includes, in percentage by weight: Al2O3 17-20%, SiO2 52-58%, CaO 3-5%, MgO 1-3%, K2O 3-5%, Na2O 1-3%, BaO 5-8%, ZnO 2-5%, SrO 2-5%.

[0017] In some embodiments of the present application, the raw material components of the suspending agent include, in parts by weight: thickening agent 2-5 parts, organic ammonia 2-5 parts, bentonite 0.5-2.5 parts, defoaming agent 0.3-0.6 parts, dispersing agent 1-3 parts, water 80-100 parts. The suspending agent has high adhesion, so that the part printed with the bright ink cannot peel off the matte transparent dry particles to form a concave-convex texture, but a planar texture.

[0018] In some embodiments of the present application, the texture of the bright ink layer is extracted from the high-brightness part of jade, and the texture includes at least one of water line, ice crack, and crystal texture.

[0019] In some embodiments of the present application, the bright ink used in the bright ink layer is bright ink K3019 produced by Shandong Guocai Kanglai New Material Technology Co., Ltd.

[0020] The second aspect of the present application provides a preparation method of the above-mentioned imitation jade ceramic tile, comprising the following steps:

[0021] The bottom glaze, soft light transparent glaze, inkjet printed color ink and bright ink, and matte transparent dry particle suspending solution are sequentially applied on the body to form a bottom glaze layer, a soft light transparent glaze layer, a color ink layer, a bright ink layer, and a matte transparent dry particle layer, respectively. After drying, the ceramic tile is obtained by kiln firing.

[0022] In some embodiments of the present application, the specific gravity of the bottom glaze is 1.85-1.95 g / cm 3 .

[0023] In some embodiments of the present application, the glaze application amount of the bottom glaze is 400-800 g / m 2 .

[0024] In some embodiments of the present application, the specific gravity of the soft light transparent glaze is 1.85-1.95 g / cm 3 .

[0026] In some embodiments of the present application, the maximum printing amount of the bright ink is 35-50 g / m2 .

[0027] In some embodiments of the present application, the application amount of the matte transparent dry particle suspension is 200-400 g / m 2 .

[0028] In some embodiments of the present application, the flow rate of the matte transparent dry particle suspension is 38-40 seconds for a 4-cup coating.

[0029] In some embodiments of the present application, the maximum temperature of the firing is 1180-1230°C.

[0030] In some embodiments of the present application, the period of the firing is 40-80 minutes.

[0031] The above technical solutions of the present application have at least the following technical effects or advantages relative to the prior art:

[0032] (1) The jade-imitating ceramic tile of the present application is provided with a body, a bottom glaze layer, a soft light transparent glaze layer, a color ink layer, a bright ink layer and a matte transparent dry particle layer from bottom to top, and through the specific layer structure, a high-fidelity jade-imitating effect with transparency, sense of gradation, sense of stereoscopic and sense of flash, and with certain light metal luster is obtained.

[0033] (2) The present application controls the chemical composition of the soft light transparent glaze, on the one hand, increases the content of SiO2 to enhance the high-brightness effect of the bright ink, and on the other hand, appropriately increases the amount of flux materials to improve the delicate and smooth effect of the glaze surface. At the same time, when the bright ink is covered on the soft light transparent glaze, light will undergo a series of optical phenomena such as reflection, refraction and scattering inside the glaze layer when passing through the bright ink layer and the soft light transparent glaze layer, thereby producing a jade-imitating effect with sense of stereoscopic, sense of gradation and sense of transparency.

[0034] (3) The present application extracts the texture of the high-brightness part in the jade design by photoshop, designs it into the effect net of the bright ink channel, and prints it on the soft light transparent glaze layer by ceramic digital printing. After the bright ink is fired at high temperature, the high-brightness texture is formed on the soft light transparent glaze, light can be reflected through the high-brightness texture part, or can pass through the high-brightness part into the soft light transparent glaze layer to undergo refraction and scattering, forming a unique optical effect.

The raw material components of the soft light opaque glaze of Comparative Example 4 include, in terms of parts by weight: potassium feldspar 30 parts, sodium feldspar 20 parts, washed soil 7 parts, calcined kaolin 2 parts, aluminum oxide 2 parts, quartz 3 parts, wollastonite 3 parts, burned talc 3 parts, dolomite 15 parts, strontium carbonate 4 parts, barium carbonate 9 parts, calcined zinc oxide 4 parts, zirconium silicate 10 parts.

[0090] The actual picture of the ceramic tile prepared in Comparative Example 4 is shown in Figure 7 .

[0091] Performance test

[0092] The gloss of the bright part and the non-bright part of the ceramic tile samples prepared in Examples 1-3 and Comparative Examples 1-4 is tested respectively, and the visual effect of the glaze and the hand touch feeling are recorded, and the results are shown in Table 1. Among them, the gloss is detected by a gloss meter.

[0093] Table 1: Performance comparison table of samples prepared in Examples 1-3 and Comparative Examples 1-4

[0094]

[0095] As can be seen from Table 1 and Figures 1-3 , the gloss of the bright part of the ceramic tile samples prepared in Examples 1-3 is 25-32°, the gloss of the non-bright part is 10-14°, and the glaze is soft, delicate, and warm in texture, without obvious glaze crystal spots; the bright effect of the glaze is transparent, with a sense of level, three-dimension, and flash, and has a certain light metal luster, with a realistic imitation jade stone effect.

[0096] Compared with Example 1, the content of SiO2 in the chemical composition and the raw material components of the soft light transparent glaze of Comparative Example 1 is lower, the bright effect of the glaze is not good, the level, three-dimension, and flash are not strong, and has a certain light metal luster, see Figure 4 .

[0097] Comparative Example 2 uses ordinary water-based protective glaze instead of the matte transparent dry particle suspension of Example 1. The faster flow rate makes the protective glaze have a peeling property on the bright ink, resulting in a concave texture on the glaze surface and a decrease in flatness. See Figure 5 .

[0098] Comparative Example 3 does not include a soft transparent glaze layer on the ceramic tile, resulting in a rough glaze surface, no soft touch, and poor bright luster effect, no level, three-dimensional, flashing, and light metal luster. See Figure 6 .

[0099] Comparative Example 4 replaces the soft transparent glaze of Example 1 with a soft opaque glaze. The opaque glaze scatters light due to its non-soft transparent or semi-soft transparent properties, making the light more evenly spread in the glaze layer, greatly reducing the bright effect, and the sense of transparency, three-dimensionality, and level. See Figure 7 .
