Detailed Description
The invention is further illustrated by the following embodiments, which are to be understood as merely illustrative of the invention and not limiting thereof. Unless otherwise specified, each percentage refers to a mass percent.
Preparing blue-white pigment.
The blue-white pigment comprises the following raw materials: 8-15 parts of cobalt oxide, 25-38 parts of frit, 1-5 parts of ferric oxide, 24-35 parts of water-washed kaolin, 1-5 parts of manganese oxide, 12-20 parts of pearl material and 1-4 parts of calcined talcum. All the raw materials of the blue-white pigment are preferably technical-grade raw materials. The blue-and-white pigment is more suitable for the kiln rapid firing schedule of the existing building ceramics.
The chemical composition of the frit comprises: the frit ,SiO2 58-70%、Al2O3 6.0-7.5%、Fe2O3 0.1-0.3%、CaO 13-18%、MgO 1.0-2.5%、K2O 2.5-3.5%、Na2O 0.2-2.5%、B2O3 1-3%、ZnO 2.5-5.5%. is capable of promoting chemical reactions at high temperatures of coloring ions such as cobalt ions, chromium ions, manganese ions, etc. in the pigment in mass percent. The introduction of ZnO widens the color temperature range of coloring ions. The introduction of MgO and B 2O3 increases the high-temperature chemical reactivity of cobalt ions, manganese ions and iron ions in the blue-white pigment. The initial melting temperature of the frit can be 1080-1115 ℃.
In the raw material composition of the blue-and-white pigment, the excessive frit content can cause excessive reaction to generate a large amount of non-static substances when the blue-and-white pigment is presintered, and a large amount of colloid ions are generated when blue-and-white ceramic ink is prepared in the later period, so that the situation of blocking a spray head in the ink printing process can be caused, and the printing performance of the ink is affected; the too low frit content can lead to the failure of pre-uniformly dispersing coloring ions when the blue-and-white pigment is presintered, and can not ensure better coloring of the coloring ions such as cobalt, manganese and the like of the ink under a rapid firing system.
As an example, the chemical composition of the water-washed kaolin clay includes: in mass percent, burn-out 12.81%、SiO2 48.23%、Al2O3 35.94%、Fe2O30.8%、TiO20.38 %、CaO 0.05%、MgO 0.12%、K2O 1.21%、Na2O 0.46%.
The chemical composition of the bead material comprises: the beading material ,SiO228-30%、Al2O333-37%、Fe2O32.0-3.5%、TiO20.3-0.5%、CuO 0.7-0.9%、MgO 0.3-1.5%、CaO 0.3-0.5%、K2O 0.03-1%、Na2O 0.2-0.5%、MnO 22-24%、CoO 5-7%. is a main color development source of blue and white pigment in mass percent and can provide cobalt ions and manganese ions. The too high content of the bead material can cause the too high reaction temperature of the blue-and-white pigment, the incomplete color development in the rapid firing process can cause color shift and black development, and the color rendering effect of the blue-and-white pigment is not achieved; the too low content of the pearl material can cause the color development of the blue-and-white pigment to be lighter, and the blue-and-white color rendering effect can not reach the expected effect.
The chemical composition of the calcined talc comprises: in mass percent, burn-out 0.7%、SiO265.8%、Al2O31.87%、Fe2O30.24%、TiO20.07 %、CaO 0.99%、MgO 29.96%、K2O 0.16%、Na2O 0.21%.
Weighing according to the raw material composition of the blue and white pigment, ball milling and mixing uniformly until the granularity is controlled to be 325 meshes less than 2wt%, and marking the obtained material as material A. Heating the material A to 1150-1300 ℃ at 5-10 ℃/min (for example, 5 ℃/min) under the oxidizing atmosphere, sintering (presintering) for 2-4 hours at 1150-1300 ℃, and crushing to obtain the blue-white pigment. In the presintering process, the mixed inorganic powder fully and chemically reacts to obtain the blue-and-white pigment mainly comprising silicate-based compound. The pulverizing means includes, but is not limited to, mechanical pulverizing, jet milling, and the like. In some technical schemes, the particle size of the powder of the blue-white pigment is preferably controlled to be D 90 & lt 8 mu m.
The blue-and-white pigment meets the requirement of medium-temperature rapid firing of a roller kiln, simultaneously has the performance requirement of preparing blue-and-white ceramic ink, and introduces a high-temperature fluxing agent (frit) to reduce the color development temperature of the blue-and-white pigment and realize good color development. The blue-and-white pigment can be matched with the existing wrapping red ink and other decorations, and can realize the special decorative effects of rare blue-and-white porcelain varieties such as blue-and-white underglaze red.
And preparing blue-and-white ceramic ink. The blue-and-white ceramic ink comprises the following raw materials: the weight percentage of the blue-white pigment is 40-50%, the white oil is 15-30%, the isooctyl palmitate and/or the isopropyl laurate is 15-20%, the dispersant is 3-10%, and the defoamer is 0.2-0.6%. Dispersing agent and defoaming agent are commercially available. For example, the dispersant may be Lamberti 1028, lamberti 1087, BYK-AT203, BYK-AT204, BYK-9076, BYK-163, etc.; as the defoamer, ning Baidi DEFOMEX 108,108, a fluorine modified organosilicon compound as a bright rainbow aid HF3107, a special polymer as a bright rainbow aid HF3012, and the like can be used. In the specific embodiment, BYK-AT203 is used as the dispersing agent, and HF3107 fluorine-modified organosilicon is used as the defoamer.
Raw materials of the blue-and-white ceramic ink are mixed uniformly according to the proportion and then are ground in a sand mill, so that the blue-and-white ceramic ink with consistent and good stability is obtained. The particle size D 90 of the blue-and-white ceramic ink is less than 1 mu m.
The preparation method of the digital decorative blue-and-white ceramic plate is also exemplified.
Applying surface glaze on the surface of the blank body. Inkjet overglazes commonly used in the art may be employed. For example, the chemical composition of the overglaze includes: the loss of firing 3.0-4.0%、SiO252-60%、Al2O320-26%、Fe2O30.1-0.3%、CaO 0.1-0.3%、MgO 0.1-0.3%、K2O 2.0-5.0%、Na2O 1.0-3.0%、ZrO24.0-6.0%. may be by drenching the glaze to apply the overglaze in mass percent. For example, the specific gravity of the overglaze is 1.86-1.88 g/cm 3 and the glazing quantity is 550-600 g/m 2.
And printing the blue-and-white ceramic ink on the surface of the green body after the overglaze is applied according to a design layout by using an ink-jet printer. The blue-and-white ceramic ink and the ceramic ink with other colors can be used together, for example, the blue-and-white ceramic ink is used as a main color tone, and the inks with other colors such as red, yellow, blue, brown and the like are used together.
And carrying out ink-jet printing on the surface Shi Touming glaze of the green body after the blue-and-white ceramic ink is printed. The chemical composition of the transparent glaze comprises: the burning-out 0.3-0.6%、SiO259-61%、Al2O312-14%、Fe2O30.1-0.25%、CaO 10-12%、MgO 1.5-2.5%、K2O 5-7%、Na2O 1.5-2.5%、BaO 0.3-0.6 %、ZnO 4-6%、Li2O 0.4-0.8%. of the alkali metal oxide and alkaline earth metal oxide in the transparent glaze promotes the color development of the blue-and-white pigment in terms of mass percent. The blue-and-white pigment and the transparent glaze are regulated and controlled to form anorthite equal crystals on the brick surface after firing, so that the blue-and-white pigment halation control method is an important mode for controlling blue-and-white pigment halation. The ZnO content of the transparent glaze can influence the transparency of the glaze layer and further influence the halation effect. Too high a ZnO content deteriorates the color development of the blue-and-white pigment. The transparent glaze provided by the invention can effectively reduce the high-temperature viscosity of the glaze, reduce bubbles in the glaze layer and well promote the color development of blue-and-white pigment. In addition, li 2 O can promote the presentation of bluish-blue hues.
As an example, the raw material composition of the transparent glaze includes: 15-25% of potassium feldspar, 15-20% of albite, 10-15% of quartz, 5-8% of kaolin, 10-20% of frit, 0.1-5% of barium carbonate, 0.1-13% of zinc oxide and 0.5-1% of lithium carbonate. The chemical composition of the frit may include: in mass percent, burn-out 0.3-0.1%、SiO250-60%、Al2O312-18%、Fe2O30.1-0.3%、CaO 5-8%、MgO 0.1-2.5%、K2O 3-5%、Na2O 1-2.5%、BaO 0.1-8%、ZnO 0.1-5%.
Glazing processes for transparent glazes include, but are not limited to, pouring, spraying, and the like. For example, the specific gravity of the transparent glaze is 1.85-1.92 g/cm 3, and the glazing amount is 400-500 g/m 2.
And (5) sintering the green body subjected to transparent glaze application in a roller kiln. The highest firing temperature is 1160-1210 ℃ and the firing time is 85-120 minutes. The firing temperature is too low to cause the firing of the glaze, and the blue-and-white pigment cannot give out vivid color; too high a firing temperature can cause the glaze to boil, and a large number of bubble defects appear. Under the firing system, the blue and white color normally scattered achieves the artistic effect of the ink and wash painting.
The ceramic plate after firing may also be polished. Polishing includes rough polishing, medium polishing, and fine polishing. For example, the parameters of rough polishing are: the belt running frequency is 40 HZ, and the swinging head swings 35HZ; the grinding block combination used for rough polishing is 240 mesh 9 group, 240 mesh 10 group and 320 mesh 1 group. For example, parameters of the mid-throw are: the belt running frequency is 53.5 HZ, and the swinging head swings 35HZ; the grinding block combination used in the polishing is 320 meshes of 2 groups, 240 meshes of 3 groups, 400 meshes of 2 groups, 600 meshes of 1 group, 800 meshes of 4 groups, 1000 meshes of 3 groups, 1200 meshes of 2 groups and 1500 meshes of 3 groups. For example, the parameters of polishing are: a belt: 35.6 HZ, swing 35HZ; the grinding block combination used for fine polishing is 2000 mesh 2 group, 3000 mesh 3 group, 6000 mesh 2 group, 8000 mesh 1 group.
The polished digital decorative blue-and-white ceramic plate can be subjected to super-clean and bright waxing treatment and then packaged into a finished product.

The blue-and-white pigment of example 3 has better blue-and-white color development under the firing schedule of the invention, because the blue-and-white pigment has relatively lower aluminum content in the formula, and the content of flux-type raw materials such as calcium oxide, potassium oxide, sodium oxide and the like in the frit is higher, cobalt ions can be better melted in the glaze layer at high temperature, and the blue-and-white pigment is favorable for presenting better blue-and-white color development state.
Comparative example 1
Substantially the same as in example 1, the only difference is that: the blue-white pigment comprises the following raw materials: the composite material comprises, by mass, 16 parts of cobalt oxide, 20 parts of a frit, 1 part of ferric oxide, 42 parts of water-washed kaolin, 6 parts of manganese oxide, 10 parts of a bead-made material and 5 parts of calcined talc. The same frit and bead as in example 1 was used.
The blue-and-white pigment of comparative example 1 was blackened under the firing schedule of the present invention, and the brick face did not exhibit a blue hue. This is because the blue-and-white pigment of comparative example 1 has a relatively high content of high-temperature oxides such as cobalt oxide and aluminum oxide and a low content of flux-like raw materials such as frit, and thus the blue-and-white pigment has a relatively high color development temperature, and cannot develop a bright blue-and-white color tone at the conventional firing temperature of 1160 to 1210 ℃.
Comparative example 2
Substantially the same as in example 1, the only difference is that: the chemical composition of the transparent glaze comprises: in mass percent, burn-out 0.15%、SiO253.4%、Al2O318.31%、Fe2O30.12%、CaO 14.65%、MgO 3.21%、K2O 4.12%、Na2O 3.14%、BaO 1.53 %、ZnO 1.25%、Li2O 0.12%.
The brick surface get confused of comparative example 2 is because the transparent glaze has high content of barium oxide, aluminum oxide and the like, the transparent glaze has high-temperature viscosity, and crystallization is easy to form a matte glaze in the kiln firing cooling stage, so that the blue-white pigment get confused is produced.
Comparative example 3
Substantially the same as in example 1, the only difference is that: the chemical composition of the transparent glaze comprises: in mass percent, burn-out 0.15%、SiO261.4%、Al2O310.31%、Fe2O30.12%、CaO 14.65%、MgO 3.21%、K2O 4.12%、Na2O 3.14%、BaO 1.53 %、ZnO 1.25%、Li2O 0.12%.
The glaze of comparative example 3 appeared a large number of bubbles and the blue-and-white pigment developed color difference. The transparent glaze has low alumina content, high content of high-temperature fluxed oxides such as calcium oxide, magnesium oxide and the like, so that the melting temperature of the glaze is low, the glaze is easy to burn in the stage of melting to form a transparent glass phase, and a large number of bubbles are generated on the glaze layer, so that the transparency and blue-and-white color of the brick surface are poor.
