Drawings
FIG. 1 is a schematic view showing the arrangement of zircon glittering particles, transparent dry particles and transparent base glaze according to an embodiment of the present invention;
wherein, the transparent base glaze 1, the transparent dry particles 2 and the zircon flash particles 3.
Detailed Description
The technical solution of the present invention is further described below with reference to the accompanying drawings and the detailed description.
A flash overglaze comprises the following raw materials: the crystal dry grains, the glue and the transparent base glaze 1, wherein the crystal dry grains are composed of zircon flash particles 3 and transparent dry grains 2.
The zircon is a colorless transparent gem, has higher refractive index and stronger dispersion, is a gem with the refractive index inferior to that of diamond in natural gemstones, is a good substitute of diamond, and can make the surface of the ceramic have the effect of diamond-like flash when being applied to ceramic overglaze.
As shown in FIG. 1, the zircon glittering particles 3 and the transparent dry particles 2 are mixed to form crystalline dry particles, and the transparent dry particles 2 are uniformly distributed around the zircon particles to form more interfaces after polishing, so that the zircon glittering particles have better refraction effect, and thus more three-dimensional and more diversified glittering effect is generated. If the transparent dry particles 2 are not uniformly dispersed, the zircon flash particles 3 are gathered together, a large-particle flaky single-surface flash effect is generated, and when the overglaze is coated on the surface of the ceramic tile, the whole flash effect is single and poor.
The invention realizes the glittering effect of the glaze surface by utilizing the refractive index difference of different transparent materials; the hardness of the flash particles of the zircon flash particles 3 is high, the glaze surface of the flash particles of the zircon flash particles has two kinds of glossiness through polishing with the transparent dry particles 2, the refraction difference and the reflection difference of products are better reflected, and therefore the ceramic tile has a better flash effect.
It is worth explaining that the flash overglaze of the invention dissolves the zircon flash particles 3 and the transparent dry particles 2 in the transparent base glaze 1, and adds a certain amount of glue in the flash overglaze, and the suspension property of the glue is utilized to disperse the zircon flash particles 3 and the transparent dry particles 2 in the transparent base glaze 1, thereby avoiding the precipitation of the zircon flash particles 3 and the transparent dry particles 2, and the zircon flash particles 3 are embedded in the transparent base glaze 1 when the bell jar is used for pouring glaze, so as to prevent the rapid precipitation of the zircon flash particles 3. Meanwhile, the transparent base glaze 1 plays roles of fluxing and filling in the whole dry particle system and supporting the zircon flash particles 3 from sinking.
After the flash overglaze is applied to the surface of the blank and is sintered, because the melting point of the zirconite flash particles 3 is high and is dissociated in the glaze melt, the flash glaze has better crystal flash effect, natural flash, rich luster and stable flash effect. Further, the flash overglaze can be applied to ceramic tiles and ceramic plates which are completely polished, so that the flash overglaze is closer to natural stone, has better decoration and competitiveness and has wider application range.
Preferably, the glue is sodium carboxymethyl cellulose aqueous solution, and the flow rate is 65-70S. The sodium carboxymethylcellulose aqueous solution is added into the glittering glaze, so that the zircon glittering particles 3 and the transparent dry particles 2 are in a stable dispersion state, and the glittering effect of the glaze is prevented from being influenced by precipitation.
Furthermore, the mass ratio of the crystallized dry particles, the glue and the transparent base glaze 1 is (3-5) to (4-5) to (2-3).
Preferably, the mass ratio of the crystallized dry particles to the glue to the transparent base glaze 1 is 4:4:2, and the prepared glittering overglaze has more points, lines and surface spaces on the surface and good glittering effect. If the transparent base glaze 1 is not added in the raw material of the flash overglaze, the flash overglaze has no flash effect, and when the mass ratio of the transparent base glaze 1 is less than 2, the flash overglaze has poor flash effect, wherein only the flash crystals in a point shape are provided, but the flash crystals in a wireless and planar space are provided. The glittering effect of the glittering overglaze is poor when the proportion of the crystalline dry particles is small, and the glittering effect of the glittering overglaze is substantially absent when the proportion of the crystalline dry particles is less than 3.
Further, the mass ratio of the zircon flash particles 3 to the transparent dry particles 2 is 2:8-3: 7.
Preferably, the mass ratio of the zircon flash particles 3 to the transparent dry particles 2 is 2:8-3:7, if the ratio of the zircon flash particles 3 is too high, reaction does not occur during firing due to high melting point of zircon, and the sintering degree of a glaze surface is influenced; if the content of the zircon flash particles 3 is too small, the effect of flash is poor.
Further, the particle size of the zircon glittering particles 3 is 40-80 meshes, and the particle size of the transparent dry particles 2 is 70-250 meshes.
If the particle size of the zircon flash particles 3 is too large, precipitation is easy to occur in the glaze, so that the glaze surface performance and the flash effect are unstable; if the particle diameter of the zircon glittering particles 3 is too small, crystals in a planar form after polishing are small, and the glittering effect is poor. Preferably, the particle size of the transparent dry particles 2 is close to that of the zircon flash particles 3, and the crystallized dry particles are more soluble in the transparent base glaze 1 after mixing. If the particle size of the transparent dry particles 2 is too large, the firing temperature of the green body is high and the green body is easy to precipitate, so that the flash effect is not good enough.
Furthermore, the glaze specific gravity of the glittering overglaze is 1.5-1.6, and the glaze flow rate is 60-80 seconds.
Specifically, the glaze flow rate refers to the flow rate of the glaze slurry. In the field of ceramics, a flow velocity cup is usually adopted to detect the fluidity of slurry and glaze slip, and an operation method adopting the flow velocity cup to detect comprises the following steps: the flow cup must be leveled prior to sensing the flow rate. And wiping the flow velocity cup by using a wet cloth to slightly wet the inner surface of the flow velocity cup, pressing the outflow port of the flow velocity cup by using a middle finger, and slowly pouring the slurry into the flow velocity cup until the surface of the slurry forms a convex liquid surface. And (5) scraping the slurry until the slurry surface and the flow velocity cup mouth are on the same plane. Then, the stopwatch is pressed on while the middle finger is loosened, the stopwatch is observed to observe the outflow of the slurry, the stopwatch is pressed to stop in time when the slurry flows to the trickling position, and the time displayed on the stopwatch is read to be the flow speed.
Preferably, the flow rate of the glaze of the flash overglaze is 60-80 seconds, and the overgreat or undersize flow rate of the glaze of the flash overglaze can influence the glaze effect when the bell jar is used for pouring glaze. When the flow rate of the glaze exceeds 80 seconds, the fluidity of the glaze is higher, so that the thickness of the glaze layer is thinner, and the glaze flash effect is poorer; when the flow rate of the glaze is less than 60 seconds, the fluidity of the glaze is low, resulting in poor flatness of the glaze.
A method for preparing flash overglaze, mix zircon flash particle 3 and transparent dry particle 2, get and crystallize the dry particle;
and mixing the crystallized dry particles in the glue and the transparent base glaze 1 to obtain the flash overglaze.
A preparation method of a ceramic tile with a glittering effect comprises the following steps:
spraying ink for printing after applying ground coat on the surface of the green brick, and then applying the flash overglaze, wherein the glazing amount of the flash overglaze is 800 minus 1650 g/square meter;
firing to obtain a fired brick, and performing full polishing on the fired brick to obtain the ceramic tile with the glittering effect.
It is worth to say that, in the existing process, the surface glaze is generally applied and then put into a kiln to be fired to a certain degree, then the glittering particle glaze is sprayed on the surface of the surface glaze, and then the firing is continued, so that the surface of the ceramic tile has the glittering effect. The glaze surface performance and the flash effect of the ceramic tile prepared by the method are unstable, and particularly, high-temperature flash materials such as zircon are easy to precipitate in the glaze, so that the content of the zircon in the glaze is influenced, and the glaze surface performance and the flash effect are poor. The flash overglaze of the invention dissolves the flash particles 3 and the transparent dry particles 2 of zircon in the transparent base glaze 1, and adds a certain amount of glue in the flash overglaze, so that the flash particles 3 and the transparent dry particles 2 of zircon are in a stable dispersion state in the transparent base glaze 1, thereby preventing the flash particles 3 and the transparent dry particles 2 of zircon from precipitating to cause unstable flash effect, and in the firing process, the flash particles 3 of zircon are not reacted and dissociated in the glaze melt due to high melting point of the flash particles 3 of zircon, while the melting points of the transparent base glaze 1 and the transparent dry particles 2 are low to melt in firing, wherein, the transparent base glaze 1 has high melting point higher than that of the transparent dry particles 2 but the melting temperatures of the transparent dry particles 2 are similar, when the transparent dry particles 2 are melted, the transparent base glaze 1 does not melt yet, thereby playing a supporting role for the dry particles of zircon; the transparent dry grains 2 and the transparent base glaze 1 are completely melted at high temperature, and the transparent base glaze 1 is completely filled between the zircon flash grains 3 and the transparent dry grains 2 at low temperature, so that the density between the zircon flash grains 3 and the transparent dry grains 2 is improved, the viscosity of the transparent base glaze 1 is high at high temperature, and the transparent base glaze plays a role in supporting the zircon flash grains 3 so as not to sink.
It is worth explaining that the flash overglaze of the invention is applied on the surface of a blank and is sintered once, so that the energy consumption is reduced, and in the sintering process, because the zircon flash particles 3 have high melting point and do not react and are dissociated in the glaze melt, the flash glaze has better crystal flash effect, natural flash and rich luster.
Specifically, when the glaze surface is polished completely, because the zircon glittering particles 3 and the transparent dry particles 2 are different in particle size and irregular in shape, points, lines and surfaces are generated after the glaze surface is polished completely, and the prepared ceramic tile has a good crystal glittering effect by utilizing the difference of the refractive indexes of different transparent materials, and the prepared ceramic tile is high in wear resistance, natural in glittering, rich in gloss and good in glittering texture. And the cutting of points, lines and surfaces generated by the crystallized dry particles leads the limited space to be infinitely extended, and adds the feeling of thickness and heaviness of the glaze surface.
Preferably, the glazing amount of the flash overglaze is 800-1650 g/square meter, and if the glazing amount of the flash overglaze is too small, the flatness and flash effect of the glaze surface in the polishing process are affected.
Further, the step of fully polishing the fired brick comprises the following steps: the following grinding heads were used in sequence for polishing treatment: 5 groups of grinding heads consisting of 240-mesh hard modules, 5 groups of grinding heads consisting of 300-mesh hard modules, 4 groups of grinding heads consisting of 120-mesh elastic modules, 3 groups of grinding heads consisting of 150-mesh elastic modules, 3 groups of grinding heads consisting of 180-mesh elastic modules, 6 groups of grinding heads consisting of 300-mesh elastic modules, 6 groups of grinding heads consisting of 400-mesh elastic modules, 7 groups of grinding heads consisting of 500-mesh elastic modules, 6 groups of grinding heads consisting of 600-mesh elastic modules, 5 groups of grinding heads consisting of 800-mesh elastic modules, 4 groups of grinding heads consisting of 1000-mesh elastic modules, 4 groups of grinding heads consisting of 1200-mesh elastic modules, 5 groups of grinding heads consisting of 1500-mesh elastic modules and 4 groups of 2000-mesh elastic modules.
The polished tile glaze is smooth and transparent by adopting the full polishing process, has point, line and surface spaces, and increases the thickness and weight of the glaze.
Furthermore, the grinding head consisting of the rigid modules and the grinding head consisting of the elastic modules exert pressure of 0.3MPa on the surface of the ceramic tile.
If the pressure applied to the glaze by the grinding head is too large, the polishing amount is too large, so that the glaze is polished to expose a bottom blank, and defects are caused. If the pressure applied to the glaze by the grinding head is too small, the polishing amount is too small, so that the polished glaze has poor flatness and poor surface layer flashing effect, more point crystals are present, and the surface crystals have less flashing.
Further, the blank body is put into a kiln for drying after being coated with flash overglaze, the drying temperature is 200-250 ℃, and after the drying is finished, a dry blank with the blank body temperature of 60-70 ℃ and the water content of 0.4-0.5 percent is obtained.
The dry blank is put into a kiln for sintering, the sintering temperature is 1190-1200 ℃, and the sintering period is 65-70 minutes.
The green body with the temperature of 60-70 ℃ after being dried can be directly fired in a kiln, so that the firing preheating step is reduced, and the energy consumption is saved. It is worth mentioning that if the weight of the water contained in the green body after the green body is put into the kiln for sintering is too large, the green body is easy to shrink unevenly inside and outside during the sintering process, so that the prepared ceramic tile has cracks with different sizes.
Due to the high melting point of the zircon flash particles 3, when the firing temperature is 1190-1200 ℃, the zircon flash particles 3 are dissociated in the glaze melt, and a better crystal flash effect is presented.
The technical solution of the present invention is further illustrated by the following examples.
