Detailed Description
The invention is further illustrated by the following embodiments, it being understood that the following embodiments are merely illustrative of the invention and not limiting thereof. Unless otherwise specified, each percentage refers to a mass percent.
The following is an example of the preparation method of the crystal flower positioning full-polished crystal glaze artistic rock plate provided by the invention with reference to figure 1.
And (5) forming by using green body powder to obtain a green brick. The chemical composition of the green body powder is prepared by adopting a conventional formula. As an example, the chemical composition of the rock slab body powder may include: siO in mass percent 2 ：50-65％；Al 2 O 3 ：20-30％；Fe 2 O 3 ：0.1-0.5％；TiO 2 ：0.05-0.3％；CaO：0.4-0.5％；MgO：0.5-1.0％；K 2 O：2.0-3.0％；Na 2 O：3.0-4.0％。
Preferably, green body powder with higher whiteness is adopted. The whiteness of the green body powder can be controlled to be 50-55 degrees.
The particle grading of the rock plate blank body powder comprises the following steps: the mass percentage is more than 30 meshes: 20-25%;30-80 mesh: 60-70%; less than 80 meshes and less than or equal to 6 percent. Wherein, above 30 mesh means the part left on the 30 mesh screen, below 80 mesh means the part passing through the 80 mesh screen. The green body powder with the grain composition can ensure the forming performance of green bricks. The moisture content of the green body powder is preferably controlled to be 8.5+/-0.3 wt%.
The raw materials of the green body powder are granulated by a spray tower, distributed by a distribution system, and then are formed into green bricks by a press. For example, the press pressure for molding was 122000KN, and the number of molding was 1.65 times/min. Of course, the green bricks can be polished by a green brick polishing machine, then put into a drying kiln for drying treatment, and subjected to green brick sweeping wetting after drying.
And applying overglaze on the surface of the green brick. The purpose is to cover the base color and flaws of the green body, which is beneficial to the color development of the ink-jet pattern. The overglaze is preferably an overglaze of a high silicon high aluminium system.
The chemical composition of the overglaze may include: in mass percent, IL:1.5-4.5%; siO (SiO) 2 ：45-60％；Al 2 O 3 ：20-30％；CaO：0.5-2.0％；MgO：0.5-2.0％；K 2 O：2.0-3.0％；Na 2 O：1.0-2.0％；ZrO 2 :6-10%. By using the overglaze formula of the high-silicon high-aluminum system, on one hand, other components in the overglaze can be reduced from reacting with crystalline substances in the crystalline polished glaze when the overglaze is melted at high temperature; on the other hand, the overglaze of the formula has higher initial melting point (initial melting temperature), and the overglaze and the crystallization polished glaze with lower initial melting point can not generate mutual penetration or generate substances influencing crystallization when being melted at high temperature. In some embodiments, the onset temperature of the overglaze may be controlled to 1060-1100 ℃.
The raw material formulation of the overglaze can comprise: the potassium feldspar comprises the following components in percentage by mass: 25-35%, albite: 10-15%, quartz: 10-20%, soil burning: 5-8% of zirconium silicate: 6-10%, calcined talc: 1-2% of wollastonite: 1-3 percent of kaolin: 10-15%. When the overglaze is prepared, the raw materials of the overglaze are evenly ball-milled by adding solvent to prepare glaze slurry. Colorants may optionally be added to the overglaze to meet color requirements. The requirement of the overglaze on fineness is that the screen residue passing through a 200-mesh screen is 0.5-0.8wt%.
The overglaze formulation employed in the present invention is different from conventional overglaze formulations. Conventional overglaze raw material formulations include, for example: the potassium feldspar comprises the following components in percentage by mass: 10-15%, albite: 30-35%, quartz: 5-10 percent of calcite: 8-15%, zirconium silicate: 5-10% of calcined talc: 6-10 percent of kaolin: 10-15%. In the conventional overglaze formula, as the potassium, sodium, calcium and magnesium components are higher, the initial melting point is lower, and the cross reaction of the components in the crystal glaze and overglaze is excessive during high-temperature melting, the crystallization effect of the crystal glaze is affected, and the crystal flower is reduced or even no crystallization effect is caused.
The overglaze may be applied by spraying. The glaze spraying process has lower requirement on the performance of the glaze slurry than that of the glaze spraying process, and is easier to control than the glaze spraying operation. The specific gravity of the overglaze can be controlled between 1.50 and 1.55g/cm 3 The glaze spraying amount can be controlled to be 320-400g/m 2 . The overglaze with the application amount can ensure the coverage area of the rock plate blank body, and reduce the defects of whiteness reduction, decorative reduction and the like caused by material emission and the like in the sintering process of the blank body. If the glazing quantity is too low, the coverage area of the overglaze on the rock plate blank body is reduced, and the coverage is low; if the glazing quantity is too high, the glaze is difficult to mature and is excessively burnt, the crystallization temperature of the crystal polishing glaze is changed, the size of the crystal flower is finally changed, and the burning process is difficult to control.
And (3) carrying out ink-jet printing on the surface of the green brick with the overglaze. The color and layout of the ink jet printed pattern may be adapted according to the ceramic rock plate design. In some embodiments, printing of no pattern may also be selected based on the rock pattern and molding effect.
And printing the glue pattern on the brick surface after the pattern is printed by the ink jet without crystallization. In particular to printing glue patterns with different grey scales having a texture effect. The glue commonly used in the art is adopted. Printing of the glue pattern may also be performed using ink jet printers commonly used in the art.
Subsequently, the brick cloth Shi Xijing suppresses dry grains (may also be referred to as grain suppression dry grains or grain precipitation suppression dry grains). The dry grain is suppressed by the dryer cloth Shi Xijing. And then removing the crystal-inhibiting dry particles on the brick surface which are not fixed by the glue. For example, a fan is used to blow away the crystal-inhibiting dry particles of which the brick surface is not fixed.
And controlling the gray level of the glue pattern to be 80-100%. The lower gray level of the glue pattern can cause the follow-up crystallization inhibition dry grain to have too small bonding amount and even not bond crystallization inhibition dry grain, thereby failing to effectively inhibit crystallization of the crystallization glaze and affecting the crystallization inhibition effect; the too high gray level of the glue pattern can cause too large bonding amount of crystal-inhibiting dry particles, and the defects of local protrusion, uneven brick surface and the like can be caused after the crystal glaze is applied, thereby influencing the decorative effect. The glue gray scale is controlled to be 80-100%, so that the effect of inhibiting local crystallization can be achieved, and a good brick surface decoration effect can be ensured.
The chemical composition of the crystallization inhibition dry particles can comprise: in mass percent, na 2 O：5.0-8.0％；SiO 2 ：55-65％；Al 2 O 3 ：10-20％；CaO：2.0-8.0％；MgO：0.1-2.0％；ZnO：2-3％；B 2 O 3 :0.2-0.5%; pbO:0.2-0.5%. On one hand, strong fluxing agents such as sodium oxide, boron oxide, lead oxide and the like in the crystallization dry particles can be inhibited to locally and rapidly reduce the crystallization temperature of the crystallization glaze, so that the crystal flowers of the crystallization glaze are melted, crystal nuclei of the crystallization glaze cannot be formed, and the crystallization inhibition effect is achieved; on the other hand, boron oxide in the crystallization-inhibiting dry grains tends to inhibit the crystallization of the crystal glazing. Therefore, the crystallization-inhibiting dry grain and crystallization polishing glaze combination provided by the invention can play a good role in inhibiting crystallization and positioning crystal flowers.
The raw material composition of the crystal-inhibiting dry particles can comprise: sodium feldspar in mass percent: 40-60%; quartz: 10-20%; kaolin: 3-5%; calcite: 3-6%; lead: 0.3-1.0%; boron oxide: 0.5-1%; zinc oxide: 2-5%; calcined talc: 0.3-1.0%.
The preparation process of the crystal-inhibiting dry particles can be as follows: raw materials are weighed according to a proportion, a small amount of water is added and mixed uniformly, and then the mixture is put into a frit furnace for melting, wherein the melting temperature can be 1500 ℃, and the melting time can be 8 hours. And pouring the completely melted frit liquid into cold water for water quenching to obtain the frit. And then processing the melted frit into dry granules.
The initial melting temperature of the crystal-inhibiting dry particles is 980-1050 ℃, preferably 1010 ℃.
The mesh number of the crystal-inhibiting dry particles can be controlled to be 120-180 meshes. The too small mesh number of the crystallization inhibition dry particles can cause the effective bonding amount of the crystallization inhibition dry particles on the glue to be smaller, thereby causing the integral deviation of crystallization inhibition effect. The excessive mesh number of the crystallization inhibition dry particles can cause the effective bonding amount of the crystallization inhibition dry particles on the glue to be larger, so that the uniformity of the crystallization inhibition dry particles filled on the brick surface is reduced, and the crystallization inhibition effect is affected; meanwhile, the grain number of the crystal-inhibiting dry grains is too large, and the phenomena that the crystal-inhibiting dry grains cannot be completely covered by the crystal-inhibiting dry grains or the brick surface is locally raised easily occur after the crystal-inhibiting glaze is applied, so that the defects of uneven brick surface and the like are finally caused.
The bonding amount of the crystal-inhibiting dry particles can be controlled between 660 and 720g/m 2 . The bonding amount of the crystallization inhibition dry particles is too small, so that the crystallization inhibition effect is poor or crystallization of the crystallization polished glaze cannot be inhibited; the bonding amount of the crystal-inhibiting dry particles is too large, so that the defects of local protrusion, unevenness and the like of the brick surface after the crystal glaze is applied can be caused, and the decoration effect of the brick surface is poor. The bonding amount of the crystal-inhibiting dry particles is controlled to be 660-720g/m 2 When the brick surface decoration method is used, the effect of inhibiting local crystallization can be achieved, and the better brick surface decoration effect can be ensured.
And polishing glaze on the surface Shi Jiejing of the green brick. In an alternative embodiment, the chemical composition of the crystalline polished glaze may include: in mass percent, IL:1.0-5.0%; siO (SiO) 2 ：40-50％；Al 2 O 3 ：4-8％；TiO 2 ：8.0-10.0％；CaO：5-15％；MgO：0.5-2.0％；K 2 O：2.0-4.0％；Na 2 O：0.5-3.0％；ZnO：20-30％；BaO：0.5-1.0％。
The crystallization glaze has a natural crystallization effect. By introducing seeding substances (zinc oxide and titanium oxide), the kiln is saturated and then supercooled in a high-temperature environment, and then crystal flowers are naturally separated out. The invention suppresses the growth of the crystal peanut at the place where the crystal grain is distributed, and the crystal flower grows normally at the place where the crystal grain is not distributed Shi Yijing, thereby achieving the decorative effect of positioning the crystal flower, which is different from the traditional method for achieving the positioning and growing of the crystal flower by distributing the crystal grain.
The raw materials of the crystallization glaze polishing comprise: the potassium feldspar comprises the following components in percentage by mass: 20-40%; quartz: 10-20%; calcite: 5-10%; calcined talc: 3-6%; kaolin: 5-10%; sodium glass powder: 5-15%; zinc oxide: 15-30%; titanium oxide: 6-15%.
The initial melting temperature of the crystal glazing can be controlled to 1030-1100 ℃, and is preferably 1050 ℃. The expansion coefficient of the crystal polished glaze can be controlled to be 6.8x10 -6 /K-7.3×10 -6 between/K. The expansion coefficient can be finely adjusted according to the combination effect between the green body and the polished glaze so as to adapt to the brick type requirement.
The application mode of the crystallization polished glaze is spraying. The spraying is suitable for the whole brick surface. The specific gravity of the crystal polished glaze can be controlled to be 1.85-1.95g/cm 3 The spraying amount is controlled to be 1200-1500g/m 2 . The main reason that the crystallization glaze is applied by adopting a glaze spraying mode is that: on the one hand, the glazing amount of the crystallization polished glaze is larger, and the problem that kiln-entering green bricks are possibly cracked due to overlarge moisture caused by too much introduced moisture due to low specific gravity of glaze slurry sprayed with glaze can be avoided by adopting a glaze spraying mode; on the other hand, the crystallization of the crystal polished glaze is greatly influenced by the thickness of the glaze amount, the glaze obtained by adopting the mode of spraying the glaze is more uniform than the glaze obtained by spraying the glaze, and meanwhile, the phenomenon of flowing glaze and sticking the bottom caused by spraying the glaze on two sides of the green brick can be avoided.
And drying the green bricks to which the crystallization polished glaze is applied. The drying temperature can be 180-260 ℃, and the moisture of the dried green body is controlled within 0.5 wt%.
And (5) feeding into a kiln for firing. The highest firing temperature of the firing is 1205-1225 ℃, preferably 1215 ℃; the firing time may be 65 to 75 minutes. The too high firing temperature can lead to the failure of glaze polishing to form crystal nucleus or the formed crystal nucleus is melted off in the high-temperature heat preservation stage so that crystal flowers can not be formed; the firing temperature is too low, and sufficient energy cannot be obtained for nucleation or the glaze cannot be fully reacted to form nuclei.
The formation of crystal flowers in the ceramic rock plate requires nucleation substances, and the zinc oxide and titanium dioxide which are used for crystal glazing are main nucleating agents. When the kiln is heated and kept warm, the nucleation substances reach supersaturation to form crystal nuclei, and the growth of crystal flowers mainly occurs in the temperature reduction and keeping warm stage of the kiln, so that the form and the size of the crystal flowers can be influenced by a firing system and a firing curve. However, when the crystallization inhibiting dry particles are overlapped with the crystallization polished glaze, the temperature and the components of the crystallization polished glaze are changed, so that crystal nuclei cannot be formed at a high temperature stage, and the crystallization inhibiting effect is achieved.
And polishing to obtain the crystal flower positioning full-polished crystal glaze artistic rock plate. The number of polishing modules may be: 100 mesh 3 group, 180 mesh 2 group, 240 mesh 2 group, 400 mesh 2 group, 800 mesh 1 group, 1000 mesh 2 group, 1500 mesh 4 group, 1800 mesh 3 group. The surface glossiness of the polished rock plate reaches more than 100 degrees. Preferably, the polished rock plate can be polished with ultra-clean bright wax to further improve the gloss and fineness of the rock plate surface.
The preparation method can obtain the crystal flower positioning full-polished crystal glaze artistic rock plate product with the brightening effect, and the obtained artistic rock plate product has good mirror surface degree after polishing, the glossiness can reach more than 100 degrees, and simultaneously has good antifouling property and three-dimensional decorative effect.
In conclusion, the invention adopts the crystal flower positioning growth and positioning inhibition crystallization technology to realize the controllable and positioning growth of the crystal flowers of the rock plate glaze layer.
