Description
Technical Field
The invention relates to the technical field of ceramics, in particular to a composite glaze layer, a ceramic plate and a preparation method thereof.
Background
In the building ceramic industry, the opaque ground glaze (commonly called as makeup soil) has strong covering effect, most of the opaque ground glaze takes substances with higher refractive index as dispersed particles, and the opaque ground glaze with good covering rate often has strong reflection effect on sunlight. Common opacifying agents for opacifying ground glaze include titanium dioxide, cerium oxide, tin oxide, zinc oxide, zirconium silicate, and the like.
Cerium oxide and tin oxide are rarely used in architectural ceramic opaque ground glazes due to the problems of high price and the like. The superfine zirconium silicate is the most common opacifier for opacifiing the ground glaze at present, has the refractive index of 1.93-2.01, is a high-quality opacifier, is widely used in the production of various building ceramics, sanitary ceramics, daily ceramics, first-level artware ceramics and the like, and has wide application range and large application amount in the processing and production of ceramic glaze materials. The zirconium silicate can be widely applied to ceramic production, and has good chemical stability, is not influenced by the firing atmosphere of the ceramic, and can obviously improve the blank glaze bonding performance of the ceramic and improve the hardness of the ceramic glaze. Zirconium silicate has a whitening effect by forming baddeleyite or the like after firing of the ceramic, thereby causing Scattering of incident light waves, which is commonly referred to as macroparticle Scattering or Mie Scattering. For the production of the ceramic tile with white background color, the whiter the ground coat is, the higher the product grade is, for example, high-grade marble ceramic tiles such as kara white, snow white and the like need the whiteness of the background color to be more than 80 degrees. The addition of zirconium silicate in the prime coat of most marble ceramic tiles is 15-20%, the whiteness is generally about 65 degrees, the use amount of zirconium silicate is continuously increased, the whiteness is not obviously increased, the flatness of the ceramic tiles cannot reach the standard, and the cost is increased, so that the performance effect or the economic benefit of the marble ceramic tiles needs to be improved urgently.
In addition, in recent years, the price of bulk commodities in the world is rising continuously, the competition among all ceramic brands is very tragic under the requirement of double carbon and double control, the best way for reducing the cost is sought through various technical advances, and technologists are gradually promoted to be new, and various technical means are adopted to seek the substitute of zirconium silicate to reduce the comprehensive cost of the ground glaze. Titanium dioxide is also an oxide with a very high refractive index, the refractive index is as high as 2.55-2.76, and the titanium dioxide has a very strong reflection effect on light and is the whitest substance in the world. Titanium dioxide is often applied to building ceramic tiles as a main component of impervious ground coatIn (1). The titanium dioxide is usually introduced in the form of conventional titanium white frits, the firing temperature is generally lower than the ring temperature of 1080 ℃, and the titanium dioxide comprises the following chemical components in parts by mass: li 2 O/Na 2 O/K 2 O2.0-8.0 parts, caO 5-18 parts, mgO 2-5 parts, siO 2 50 to 75 portions of Al 2 O 3 3 to 6 portions of B 2 O 3 0 to 3 portions of ZrO 2 0 to 5 portions of P 2 O 5 0 to 5 portions of TiO 2 3 to 10 portions of BaO and 0 to 2.0 portions of BaO. However, titanium dioxide is a polycrystalline oxide, and titanium is typically Ti in silicate glass systems at temperatures in excess of 1000 deg.C 4+ The valence state exists. Ti (titanium) 4+ Meaning the nuclear outermost electron 3d of titanium 2 4s 2 All losses, all voids in the d orbital, no "d-d" transitions between electrons in the d orbital can occur, so Ti 4+ The valence state should appear colorless. However, due to Ti 4+ The ions strongly absorb ultraviolet rays, and the absorption band of the ions usually enters into the violet part of a visible light region, so that titanium dioxide (titanium is in a valence of + 4) existing in a rutile crystal form after being fired has a strong absorption effect on violet light, and a glaze surface is yellowed; after the impermeable ground glaze adopting the conventional titanium white frit is sintered for 60min in a kiln at the environment temperature of 1100-1150 ℃, the crystalline phase content of titanium sphene generated by the solid-phase reaction of titanium dioxide and wollastonite is reduced, the crystalline phase content of wollastonite is increased, the content of enstatite mineral phase is increased to be more than 2wt%, the glossiness of the sintered body is more than 40 ℃, the sintered body is gradually changed from milky white into translucent, and the whiteness of blue light is greatly reduced and is generally lower than 55 ℃; the b value representing yellow tone in the Lab value is generally more than 6, so the sintering temperature of the conventional titanium white impervious ground coat used for building ceramic wall and floor tiles needs to be lower than 1100 ℃.
Chinese patent CN 111499202A discloses a high solar reflectance opacified titanium white glaze and a preparation method thereof, the opacified titanium white glaze with high solar reflectance in the invention can be applied to porcelain tiles fired at 1150 ℃, can weaken the defect that the glaze surface of a ground glaze is yellowish due to the ultraviolet absorption effect of rutile titanium dioxide, but has a plurality of limitations and defects in truly realizing stable industrial application:
(1) For producing ceramics in practiceThe patent reports that titanium sphene crystal grains are used as crystal seeds to induce titanium dioxide and calcite to react to generate titanium sphene crystal phases with the grain diameters of 450-600 nm, a large amount of calcite needs to be added, so that the ground glaze can completely react without yellowing, the glossiness of the ground glaze is very high after the ground glaze is fired at the actual kiln temperature, and a large amount of aluminum needs to be added to inhibit the luster (the content of aluminum oxide in the patent reaches 19-21 percent), and in a silicate system with high titanium content, more cations Al with the characteristics of an intermediate type exist 3+ In the case of (2), rutile titanium dioxide of an appropriate particle size is easily precipitated, resulting in yellowing of the glaze;
(2) After the ground coat is applied, ink-jet decoration is required in the subsequent process, and most of the ink-jet ink components with different colors contain spinel minerals and various variable-valence transition metal chromophoric elements. Therefore, with the rise of the firing temperature, the titanium sphene crystal phase in the ground glaze silicate glass system reacts with the spinel mineral in the ink-jet ink to generate rutile type titanium dioxide, and the glaze surface turns yellow and green. In addition, in silicate glasses, titanium is generally Ti 4+ The valence exists, and from the above discussion, ti is known 4+ The valence state causes it to appear yellow. Albeit Ti 4+ The pigment does not cause darker color independently, but can strongly influence the color generation of other variable valence transition metal elements, and the color generation can still be realized even if the content of the variable valence transition metal elements is small, particularly the iron is obvious, and the most obvious example is the color generation of a plurality of pigments which are usually TiO 2 And is mixed with other toner components to realize: tiO 2 2 With Fe 2 O 3 The mixture turns brown (this is mixed with Fe) 2 O 3 And MnO 2 Similar in color); tiO 2 2 And MnO with MnO 2 The combination is light yellow to dark yellow; tiO 2 2 Combined with NiO to be gray to yellow brown; tiO 2 2 Combined with CuO, the green color is blue; tiO 2 2 With CeO 2 The mixture is used to present bright yellow; chrome titanium yellow is also a rutile type structure pigment. Thus, as the firing temperature increases, the ground-glaze silicate glass systemMiddle Ti 4+ The valence state (such as residual titanium dioxide) is easy to induce the color development effect of various valence-variable transition metal color development elements in the ink-jet ink so as to change the color development of the ink-jet ink. Further, when the content of CaO in the ground glaze formula is more than 10%, the color development of the brown series of the ink-jet printing is extremely unfavorable. In conclusion, the titanium white base coat in the patent relatively easily causes the inkjet ink of each channel to be obviously yellowish green or change tone (the b value representing yellow tone in the Lab value is seriously larger), the color gamut, the strength and the tone of the inkjet ink are greatly influenced, and even serious color difference (the delta E value representing the total color difference in the Lab value is far larger than 4) occurs in production, so that the plate-to-plate is not produced.
Accordingly, there is a need for improvements and developments in the art.

In order to solve the problems that the glaze surface gloss is high, the ground glaze is yellowish green or the phenomenon of tone change and the like of the conventional titanium white ground glaze which replaces the zirconium white ground glaze is still to be improved after the conventional titanium white ground glaze is fired, in a further embodiment of the invention, the titanium white ground glaze layer comprises the following raw materials in parts by mass:
35 to 45 portions of titanium white clinker, 0 to 10 portions of calcined kaolin, 3 to 8 portions of wollastonite, 0 to 35 portions of potassium feldspar and albite, 15 to 45 portions of quartz and 5 to 15 portions of kaolin;
the titanium white frit comprises the following chemical components in parts by mass:
SiO 2 57 to 70 portions of Al 2 O 3 5 to 7 portions of CaO, 15 to 19 portions of CaO and TiO 2 12 to 15 portions of MgO0.1 to 0.6 portion and K 2 O2.4-4.6 parts, na 2 0.1 to 1.2 portions of O and 0.2 to 0.5 portion of loss on ignition.
In this embodiment, the titanite is used to synthesize CaO. TiO 2 ·SiO 2 The principle is that the content of alumina and calcium is reduced, the content of quartz is greatly improved, magnesium is removed, titanium is extracted, and the content of calcium is introduced in a wollastonite mode. Titanium white emulsion composed of the raw materialsThe turbid ground glaze can enable titanium dioxide and wollastonite to carry out solid phase reaction to synthesize titanium titanite without enabling the titanium dioxide to exist in a rutile crystal form in the sintering process with the environment temperature of 1100-1150 ℃ and the sintering period of 60min, so that the yellowing tendency of rutile titanium dioxide is better inhibited, and the glaze surface is not yellowed. The content of the titanium titanite crystal phase in the composition of the characteristic phase after sintering in the kiln is 13-21 wt%, the content of the wollastonite crystal phase is 6-12 wt%, and the characteristic phase does not contain enstatite ore phase. The titanium white opaque ground glaze provided by the invention can adapt to the firing temperature of more than 1100 ℃, the glaze surface after firing has low glossiness (the glossiness can be controlled between 3 and 8 ℃), the glaze surface does not yellow, and the whiteness of blue light is more than 65 ℃. The titanium white opacified ground glaze provided by the invention is more suitable for decoration application as the ground glaze, greatly improves the stability and applicability of the titanium white opacified ground glaze in high-temperature sintering, and can completely replace the existing zirconium white ground glaze. The titanium white base coat and the isolation glaze layer are matched with each other, the titanium white base coat has high blue light Baidu, the isolation glaze layer ensures the whiteness of the titanium white base coat and simultaneously better avoids the inhibition of the titanium white base coat with high calcium content on the color development of brown series ink, avoids the preferential reaction of the crystal phase of titanium sphene synthesized in the titanium white base coat and spinel minerals in ink-jet ink to generate rutile titanium dioxide, so that the glaze surface turns yellow and green, and avoids the Ti in the titanium white base coat 4+ The color development effect of various color development elements of the variable-valence transition metal in the ink-jet ink is induced to cause the tone of the ink-jet ink to be changed, so that the color gamut, the strength and the color tone of the color development of the ink-jet ink are not influenced.
The titanium white frit is used as an opacifier to play a role in whitening, and a large amount of titanium sphene crystal phase is synthesized in the process of firing the ground glaze, so that the hiding power of the ground glaze is increased. The material of magnesium, alumina or corundum crystal phase can accelerate the reaction of generating rutile crystal phase, and in the embodiment of the invention, the titanium white frit does not contain magnesium component, the material content of alumina or corundum crystal phase is very little, and the titanium white opacified ground glaze is in titanium sphene crystal phase and does not contain enstatite ore phase in the composition of the characteristic phase after being fired.
Calcium is an alkaline earth metal element, calcium oxide is a fluxing agent in the glaze, the melting temperature of the glaze can be rapidly reduced due to the high calcium proportion, the liquid phase for dissolving the glaze is increased, and more color particles are corroded and dissolved due to the increase of the liquid phase, so that the color development of the ink-jet ink is influenced. In the embodiment of the invention, calcium is introduced in the form of wollastonite, the content of calcium is less, the color development of ink is not influenced, and meanwhile, the addition of the wollastonite can also play a role in cooling.
Silica is introduced into the titanium white opacified ground coat by adding quartz, and a part of the silica forms a glass network agent to promote sintering; part of the titanium dioxide opal ground coat still exists in cristobalite, the firing temperature of the titanium dioxide opal ground coat is improved, and the glossiness of the glaze surface is reduced.
The potassium feldspar and the albite are used as a flux, so that the sintering is promoted, and the whiteness of the glaze surface can be further improved.
The aluminum oxide or silicon dioxide is introduced into the kaolin, so that the maturation temperature of the titanium white opaque ground coat can be increased, and the effects of whitening and reducing the glossiness are achieved.
The calcined kaolin introduces alumina and silica into the titanium white opaque ground coat, which can increase the maturation temperature of the titanium white opaque ground coat and play a role in whitening and reducing the glossiness of the glaze surface in the titanium white opaque ground coat. Therefore, the addition of the calcined kaolin further improves the whiteness of the glaze and reduces the glossiness of the glaze.
In the present example, the specific ratio of potassium feldspar and albite is not limited, and the sum of the potassium feldspar and albite is 0 to 35 parts, and in a further embodiment, the sum of the potassium feldspar and albite is 0 to 35 parts, but not equal to 0.

In one embodiment, the chemical composition of the titanium white frit comprises, in parts by mass:
SiO 2 58.7 to 70 portions of Al 2 O 3 6.2 to 7 portions of CaO, 16 to 19 portions of CaO and TiO 2 13.8 to 15 portions of MgO 0.2 to 0.6 portion of K 2 O2.4-3.6 parts, na 2 0.1 to 1.2 portions of O and 0.2 to 0.3 portion of loss on ignition.
In one embodiment, the chemical composition of the titanium white opacified ground glaze comprises the following components in parts by mass:
SiO 2 62 to 80 portions of Al 2 O 3 3 to 13 portions of CaO, 7 to 9 portions of CaO and TiO 2 4 to 5 portions of Fe 2 O 3 0.05 to 0.21 portion, 0.1 to 0.3 portion of MgO and K 2 1.4 to 3.0 portions of O and Na 2 0.1 to 0.8 portion of O and 1.0 to 1.5 portions of loss on ignition.
The embodiment of the invention also provides a ceramic plate, which comprises a ceramic blank and an ink-jet decorative layer, and further comprises the composite glaze layer arranged between the ceramic blank and the ink-jet decorative layer, wherein the titanium white ground glaze layer in the composite glaze layer is arranged to be attached to the ceramic blank, and the isolation glaze layer in the composite glaze layer is arranged to be attached to the ink-jet decorative layer. In the embodiment, the isolation glaze layer is arranged on the titanium white ground glaze layer and the ink-jet decorative layer, so that the possibility that various ink-jet inks are in direct contact with the titanium white ground glaze can be effectively reduced: avoid the preferential reaction of the crystal phase of the titanite synthesized in the titanium white ground glaze and spinel minerals in the ink-jet ink to generate rutile titanium dioxide, so as to avoid the yellow and green glaze surface and avoid Ti in the titanium white ground glaze 4+ The color development effect of various valence-variable transition metal color development elements in the ink-jet ink is induced to cause the tone of the ink-jet ink to be changed, so that the problem that the ink-jet ink of each channel is obviously yellowish green or changed in tone is avoided.
In the above embodiment, the isolation glaze layer is provided on the titanium white ground glaze, so as to theoretically avoid direct contact between the titanium white ground glaze and the inkjet ink, and to better solve the problem that the spinel minerals in the inkjet ink preferentially react with the crystalline phase of titanium titanite synthesized in the titanium white ground glaze to generate rutile titanium dioxide and Ti 4+ Influence variable valence transition metal hairThe problem of color generation of color elements is solved, but the current production equipment and process technical scheme still do not have practical implementation feasibility, and particularly for large-size ceramic plates (ceramic rock plates and ceramic thin plates), industrial production cannot be realized, and the existing production equipment and process technology still have a lot of spaces for improvement. For example, a rock plate blank with the thickness of 3mm is thin, the production difficulty is high, and only in terms of the glazing process, the existing common bell jar glaze spraying, water jet glaze spraying, ink jet printing digital glaze and the like have more or less problems. When the glaze throwing cabinet is adopted for glazing, the atomization capability and the implementation area are very limited, the general work ratio weight average is lower than 1.40, the maximum green body glazing area is difficult to exceed the specification of 800mm, and the glaze surface flatness is not ideal; the high-pressure automatic glaze spraying system can be used for large-area glazing of large-sized ceramic plate products, but the working specific gravity of the system is generally lower than 1.55, and once the glazing amount is less than 300g/m 2 The flatness of the glaze surface cannot meet the requirement; the best advantage of adopting bell jar to spray glaze is that the specific gravity can exceed 1.70, the flatness is good, the moisture in the kiln is relatively low, but once the glazing amount is less than 300g/m 2 Difficult problems to implement; the glaze pouring is easy to break and branch. The biggest defect of adopting the devices is the ceramic plate specification problem, because once the specification exceeds 1.2m, the device precision is difficult to control, the operation is difficult to implement, the requirements on the glaze line yield and the glazing amount are also greatly limited, generally the linear speed is difficult to exceed 30 m/min, and a plurality of production defects such as net sticking and the like are easy to occur; the amount of each square glaze is hardly more than 80g, obvious ripple defects exist, the process requires skilled technical workers, and the steps of processing and using the glaze, and customizing links such as a flat screen, a rubber roller and the like are added; the ink-jet printing digital glaze is mainly prepared from oil ink, the working specific gravity is less than 1.40, and the single-channel glazing amount is difficult to exceed 40g/m 2 The ink-jet ink has high cost due to special requirements on oily solvents, additives and ink particle sizes, and the unit price is between 3 and 12 ten thousand per ton.
Based on the above, the embodiment of the invention further provides a preparation method of the ceramic plate, which can effectively solve the difficult point of the glazing process of the ceramic rock plate and the ceramic thin plate, wherein the preparation method comprises the following steps:
s1, providing a ceramic blank;
s2, forming a titanium white base glaze layer on the surface of the ceramic blank;
s3, mixing the raw materials of the insulating glaze layer, water and additives according to the raw material components and the mass part ratio of the insulating glaze layer, so as to form an insulating glaze slurry, and spraying the insulating glaze slurry on the titanium white ground glaze layer by adopting an electrostatic spraying method, so as to form an insulating glaze layer;
and S4, forming an ink-jet decorative layer on the surface of the isolation glaze layer, and firing to obtain the ceramic plate.
The preparation method provided by the embodiment can successfully realize the application of the isolation glaze on a large-area ceramic rock plate or ceramic thin plate, not only solves the technical bottleneck that a layer of thin glaze cannot be stably and uniformly distributed on a large-size product by the traditional technical means, but also enables the color gamut and the color development intensity tone of the ink-jet ink to achieve the technical effect which is not different from the ink-jet on the conventional zirconium white cosmetic ground glaze.
The embodiment of the invention does not limit the raw materials and the mixture ratio of the ceramic body in the step S1.
In step S3, in one embodiment, 100 parts by weight of the raw materials of the insulating glaze layer described above in the embodiments of the present invention, 0 to 3 parts by weight of the additive, 40 to 95 parts by weight of water and the aqueous suspension stabilizer are added to a ball mill, mixed and then intermittently ball-milled for 6 to 15 hours until the obtained slurry can completely pass through a 325-mesh screen, thereby obtaining the insulating glaze slurry.
In one embodiment, the additive comprises the following components in parts by mass:
0.3 to 0.5 portion of sodium tripolyphosphate, 0.1 to 0.25 portion of sodium carboxymethyl cellulose, 0 to 2 portions of conductive agent and 0 to 1 portion of surfactant.
In one embodiment, the conductive agent is selected from at least one of basf EFKA VOK-6782 conductive agent, BYK-ES80, add-in FD1092, octadecyl dimethyl hydroxyethyl quaternary ammonium nitrate (EA 562), but is not limited thereto.
In one embodiment, the surfactant is selected from at least one of AEO-9, mesohm 400, but is not limited thereto.
In one embodiment, the water and aqueous suspension stabilizer has a mass ratio of (30-60) to (10-35) in the water and aqueous suspension stabilizer.
In one embodiment, the aqueous suspension stabilizer is selected from at least one of methyl glycol, bentonite, polymethylsiloxane, ammonium polyamic acid formulation, STELLMITTEL506 (manufactured by suma chemical company, germany), sumapeptopon 5, peptappon 5 (manufactured by suma chemical company, germany, swelling compound), but is not limited thereto.
In one embodiment, the particle size of the particles in the isolation glaze slurry is D97-45 μ M, the specific gravity of the isolation glaze slurry is 1.20-1.40, the flow rate of the isolation glaze slurry is 11-13 s, the pH of the isolation glaze slurry is 7-8, and the resistivity of the isolation glaze slurry is 1.2M omega-cm or less. In the embodiment, the particle size of the particles in the isolation glaze slurry is D97 not more than 45 μm, so that the defects of good suspension property of the isolation glaze slurry, low melting temperature of glaze, tight combination of glaze blanks, small drying shrinkage rate of a glaze layer, difficult generation of cracks and the like can be ensured. In addition, the pH value of the isolation glaze slurry is 7-8, and the isolation glaze slurry is not easy to agglomerate.
In one embodiment, the barrier glaze slurry is sprayed on the titanium white base glaze layer by an electrostatic spraying method to form a barrier glaze layer. The embodiment can uniformly spray a layer of isolation glaze layer with the specific gravity between 1.20 and 1.40 on the titanium white ground glaze layer, solves the technical bottleneck that a layer of thin glaze cannot be stably and uniformly distributed on a large-size product by the traditional technical means, and enables the color gamut and the color development intensity of the ink-jet ink to achieve the technical effect of no difference from the ink-jet on the conventional zirconium white cosmetic clay.
In specific implementation, an electrostatic spraying method is adopted on a disc type electrostatic spraying device (the working voltage is set to be 50-75 KV) and the voltage is 30-100 g/m 2 The insulating glaze slurry is sprayed on the titanium white ground glaze layer to form an insulating glaze layer. The invention applies the disc type electrostatic spraying device to the spraying of the isolation glaze layer, and successfully sprays the isolation glaze layer on the large-area titanium white base glaze layer.
A disc type (also called omega) electrostatic spraying device adopts a disc type atomizer as a spraying center, and a workpiece moves around the disc along an omega-shaped track. When the spraying device works, the disc rotates at a high speed and moves up and down in a reciprocating manner, and after entering a spraying area, a workpiece can rotate 90-360 degrees or rotate continuously as required, so that the efficiency of the atomizer is fully exerted, the spraying geometric space is enlarged, and the spraying device is an ideal spraying method. The rotary disc atomizing disc is a main part of a disc type electrostatic automatic paint spraying machine and plays a role in atomizing an isolation glaze layer, and the uniformity and the size of atomized particles of the isolation glaze layer are directly related to the isolation glaze layer. The electrostatic atomizing disc is arranged at the connecting end of the pneumatic high-speed motor, the isolation glaze layer is quantitatively conveyed to the inner wall of the disc by a pump and is thrown out to the bottom small hole of the disc through high-speed centrifugal rotation to form mist-shaped tiny particles; the fog-like isolation glaze layer with negative electrode static is quickly adsorbed to the positive electrode workpiece (grounding positive electrode) to complete the operation of electrostatic spraying isolation glaze layer.
In step S4, in one embodiment, an inkjet decoration layer is formed on the surface of the isolation glaze layer, and then a cover glaze is sprayed on the inkjet decoration layer, and the ceramic plate is obtained after firing.
In the present embodiment, the specific raw materials and composition of the overglaze are not limited.
