Detailed Description
The present invention is further illustrated by the following examples, which are to be understood as merely illustrative and not restrictive. The following percentages are by mass unless otherwise specified.
Disclosed herein is a method for preparing a flexible pattern porcelain archaized tile. Flexibility means that the product has a cut product which can be later cut into different products according to the sizes of different die line areas or cut into the same size with random position change according to requirements.
First, a green body is prepared. In one embodiment, the green body is pressed with a mold having a variety of stylized textures and registration dimensions. Different from common lines, concave-convex and special-shaped textures, in the embodiment, the mold patterns are positioned on the same blank body, and the mold patterns in each positioning size have larger pattern difference. The mould can have different depths and textures at different positions, and has abundant texture patterns. Therefore, the surface of the prepared green brick also has abundant texture patterns, and particularly can have a fine engraving effect. The grain pattern on the surface of the green brick can be matched with the ink-jet printing pattern.
The mould with various design style textures and positioning sizes can be obtained by positioning and carving various textures on a common mould or a single concave-convex mould. The carving method is preferably laser carving, and the laser carving method can perfectly express fine design and has fine and smooth section through high-power energy non-contact cutting. The material of the mould can be resin material, preferably high-strength resin material, which is temperature-resistant and not easy to soften, so that the good carving shape and detail can be kept.
In one embodiment, the pattern patterns of multiple effect elements are combined on a single mold, and the proportional sizes of the elements are aesthetically assigned. Different engraving processes and depths are selected for different element patterns, and the pattern patterns have different heights, heights and sizes, so that ink can be adsorbed and dispersed differently, and the change of the connection and disconnection depths of the patterns is formed. The height difference of the pattern can be 0.2-1.5 mm. The number of modules can be 4-10. The area ratio of each module can be between 1 and 10. The whole module area can be between 0.36 and 2.88 square meters. FIG. 1 illustrates a die design texture and layout in accordance with one embodiment of the present invention. In the embodiment, the die adopts five-type combination, and five different design effects are achieved.
Then, a base coat is applied on the green body. In order to avoid influencing the fine engraving effect on the surface of the blank body, the ground glaze is preferably low in glazing amount, strong in covering property and bright in color development.
The content of aluminum and potassium in the ground coat can be higher, so that the firing temperature range is widened, and under the same glazing amount, the covering stability change and the color development change are small. For example, the content of aluminum oxide in the ground coat can be 22-26%, and the content of potassium oxide can be 3.3-4.4%. In a preferred embodiment, the formula of the ground coat comprises the following chemical components: loss on Ignition (IL): 6.5-7.5%; SiO 22：45～53％；Al2O3：22～26％；Fe2O3：0.05～0.3％；TiO2：0.05～0.3％；CaO：6.0～8.5％；MgO：3.3～3.8％；K2O：3.3～4.4％；Na2O：0.2～0.5％；ZnO：1.2～2.5％；ZrO2: 6-10%. The ground coat can play a stronger role of covering under a lower glazing amount and has bright color development.
The ground coat preferably contains ultra-fine aluminum to enhance color development. The superfine aluminum refers to aluminum-containing raw materials with superfine particle sizes. For example, the particle size of the ultra-fine aluminum may be 325 to 400 mesh calcined alumina.
The ground glaze can be made into ground glaze slurry for distribution. The application method can be glaze spraying, glaze pouring and the like. In a preferred embodiment, high-pressure glaze spraying is adopted, and the glaze spraying pressure can be 8-12 MPa. Ground glaze slipThe specific gravity of (A) can be 1.40-1.46 g/mL. The glazing amount is preferably low, for example, the application amount of the ground glaze slurry can be 360-380 g/m2。
Then, ink-jet printing is performed on the ground coat. The ink-jet printed pattern can be suitably varied in color to interact with the blank pattern, as shown, for example, in FIG. 2. The ink can be printed by a digital ink-jet printer. The ceramic ink used may be blue, brown, orange, lemon yellow, black, red, etc. Preferably, inkjet 3D printing may be performed.
After drying the ink, semi-transparent jade composite dry grain glaze (composite dry grain for short) is distributed. The ink drying method may be, for example, electro-drying.
The semi-transparent jade composite dry grain glaze is semi-transparent after being fired, and the surface effect is dry grains on the surface of the jade after being softly polished. The semi-permeable jade composite dry grain glaze can comprise three dry grains: matte transparent dry granules, brilliant transparent dry granules, and wear-resistant anti-skid dry granules.
The matte transparent dry pellets are dry pellets that are matte and transparent after firing (the matte gloss is generally 25 degrees or less, and they have slight transparency). In one embodiment, the matte transparent dry granules are high-temperature matte transparent dry granules, and the formulation ingredients are as follows: loss on ignition by mass: 0 to 0.3 percent; SiO 22：50～60％；Al2O3：18～24％；CaO：7.0～10.0％；MgO：2.0～3.5％；K2O：4.1～5.2％；Na2O: 0.1-0.5%; ZnO: 4.5-5.5%; SrO: 1.5 to 2.5 percent. The firing temperature of the matt transparent dry particles is 1180-1200 ℃, the gloss after firing is 10-14 ℃, the melting point is high, the air is easy to exhaust, the bright sublevel effect of the surface of a product can be improved, air holes are reduced, and the antifouling performance is improved.
The content of the matte transparent dry particles in the semi-transparent jade composite dry particle glaze is preferably higher, for example, 65-75 wt%. If the content is too high, the gloss of the tile surface is lowered and the transparency is poor.
The crystal bright transparent dry granules are dry granules which give out bright flashing visual effect after being burnt and have good permeability. The crystal bright transparent dry granules can adjust the semi-transparent jade texture of the composite dry granules. In one embodiment, the formulation of the brilliant transparent dry granules comprises the following components: by massLoss on ignition: 0 to 0.3 percent; SiO 22：63.1～71.2％；Al2O3：9.3～11.9％；CaO：9.0～11.5％；MgO：1.5～2.5％；K2O：2.6～3.7％；Na2O：2.5～3.5％；ZnO：1.0～2.15％。
The content of the crystal bright transparent dry particles in the semi-transparent jade composite dry particle glaze is preferably 20-30 wt%. If the content of the pigment is too low, the brick surface has low transparency and weak color rendering; if the content of the polishing agent is too high, the glossiness of the brick surface is higher, the contrast between the soft polishing and the non-polishing is not enough, and the gloss level is unclear.
The wear-resistant and anti-skid dry particles can improve the wear-resistant and anti-skid capacity of the surface of the product. In one embodiment, the formula of the wear-resistant anti-skid dry granules comprises the following components: loss on ignition by mass: 0.0-0.3%; SiO 22：45.2～51.05％；Al2O3：20～25％；CaO：14.0～16.5％；MgO：0.25～1.0％；K2O：3.0～4.5％；Na2O: 0.0-0.2%; ZnO: 5.0 to 8.0 percent. By adopting the wear-resistant anti-skid dry particles, the wear resistance of the product can reach 4 grades, so that the product has durability and an anti-skid effect.
The content of the wear-resistant anti-skid dry particles in the semi-permeable jade composite dry particle glaze is preferably 5-10 wt%. If the content is too low, the wear-resistant and anti-skid properties of the surface of the product are insufficient; if the content is too high, the product may be too coarse.
The fineness of the three dry particles, namely the matte transparent dry particles, the crystal bright transparent dry particles and the wear-resistant anti-skid dry particles, can be selected according to the principle that the wear-resistant anti-skid dry particles can be dispersed in the matte transparent dry particles and the crystal bright transparent dry particles, so that the texture of the dry particle surface is maintained, and the anti-skid force is increased. For example, in one embodiment, the fineness of the matte transparent dry particles is between 90 and 150 meshes, the fineness of the brilliant transparent dry particles is between 60 and 120 meshes, and the fineness of the wear-resistant anti-skid dry particles is between 100 and 160 meshes.
According to the invention, by matching the matte transparent dry particles, the crystal bright transparent dry particles and the wear-resistant anti-skid dry particles, the brick surface has a bright matte hierarchical effect, few pores after burning, semi-transparent jade texture, wear resistance and skid resistance. The composite dry grain effect is mutually superposed with the blank pattern effect and the ink-jet pattern effect, so that the color and the level of the ceramic tile are more abundant and changeable.
In one embodiment, the semi-permeable jade composite dry glaze is prepared into slurry (dry slurry) and applied. In the preferred embodiment, the thin-method slurry pouring process is adopted for glazing, so that the mold surface and the layering effect of the product can be kept, the color is bright and strong, and the production and use cost is reduced. The thin method slurry pouring process is to apply a thin uniform glaze layer in a glaze pouring mode, the glaze application amount is low, and the effect under the glaze layer is slightly influenced. The main purpose of the slurry spraying process by the thin method is to make the glaze layer thinner, reduce the glazing amount, and maintain the surface uniformity, if the glaze layer is sprayed with glaze, the uniformity of the glaze layer will be deteriorated.
In order to keep the good flowing property of the dry particle slurry when the glazing amount is low, a binding agent can be added into the composite dry particles to increase the dispersibility and the flowability among the dry particles. In one embodiment, a dry pellet slurry comprises: 40-50 parts of composite dry particles and 100-110 parts of adhesive by mass. The adhesive comprises the following formula proportion: 55-65 parts of water, 2.0-3.5 parts of sodium carboxymethylcellulose, 15-20 parts of ethylene glycol, 4.5-5.5 parts of acrylic copolymer, 3-5 parts of polyurethane and 3.5-5 parts of sodium polycarboxylate. The adhesive has excellent fluidity and dry particle dispersing effect.
The flow rate of the dry particle slurry can be 30-36 seconds per cup. The flow rate here means that a 100ml flow cup is filled with a sample, a small hole (diameter of 0.5mm) is opened in the bottom of the flow cup, and the time from the start to the end of the flow of the sample is defined as the flow rate of the sample.
The specific gravity of the dry particle slurry can be 1.32-1.36 g/mL. The application amount of the dry particle slurry can be 340-380 g/m2。
And (3) applying the semi-transparent jade composite dry grain glaze, drying and sintering. The firing period can be 55-60 minutes, and the maximum firing temperature can be 1200-1225 ℃.
After firing, the thickness of the ground coat layer can be 0.08-0.12 mm, and the thickness of the semi-transparent jade composite dry grain glaze layer can be 0.10-0.15 mm.
After firing, soft polishing is preferably carried out, so that the luster of the surface jade crystal grains is effectively improved. In one embodiment, the soft polishing is performed by using a high-number elastic modules, and the number of the elastic modules can be 2000-3000.
In the method, the flexible die is used and matched with a pattern color design which is suitable for change, the dry grain slurry with semi-transparent jade is applied to the surface of the brick by thin method slurry spraying, and the luster of the grains with transparent jade on the surface is effectively improved by the soft polishing process.
After the soft polishing, the surface of the brick is polished to be crystal-clear and transparent, and is like ice balls which are hidden at different positions of the surface of the brick and are larger or smaller or longer or shorter.
The porcelain tile disclosed by the invention is integrated with non-skid and non-rough porcelain tiles, and has no obvious defects of pinholes, glaze bubbles and the like on the surface. And the wear resistance reaches 4 grades, and the wear resistance has excellent durability.
