Abstract
The invention discloses transparent particles for ceramics and ceramic tiles thereof, wherein the transparent particles comprise the following components: 100 parts of basic transparent raw materials and 0-10 parts of coloring agents, wherein the chemical compositions of the basic transparent raw materials comprise silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide, sodium oxide, potassium oxide, barium oxide, zinc oxide and fluorine. According to the transparent particles for ceramics, the composition of the particles is reasonably designed, so that after the particles are positioned on the surface of a green body, the local sintering temperature of the green body can be reduced, meanwhile, the green body cannot be greatly deformed, meanwhile, the melt-blown condition is avoided, the bubbles of the transparent particles are less, the particles are basically melted and flattened after sintering, the manufactured ceramic tile has a vivid transparent feel, the design of the ceramic tile is rich in layering sense and diversified, and the effect can be achieved through one-time sintering, so that the transparent particles are particularly suitable for preparing marble-like ceramic tiles.
Description
Technical Field
The invention belongs to the field of ceramics, and particularly relates to transparent particles for ceramics and ceramic tiles thereof.
Background
In recent years, the problem of industry difficulty is that the blank secondary material distribution particles of ceramic tiles are always the problem, the existing secondary material distribution particles are all based on blank powder, and are granulated by adding pigment, and the ceramic tile secondary material distribution particles are only applied to ceramic tiles and are only characterized by mechanical combination without vitality among different blank color blocks, and have no strong ceramic tile decoration effect due to dead boundaries.
Natural marble has a certain grain, and can reflect or refract light to exhibit natural flash point and transparent feeling due to the existence of larger or smaller crystals inside. The advantages of natural marble are becoming increasingly popular. Thus, the development of ceramic tiles has been largely surrounded by lines, colors, feel, flash points, etc. that imitate some natural marble. The grain and color of marble can be realized by ceramic ink, flash point can be realized by diamond dry particles, ice crystal dry particles, mica and the like, and the marble transparent particles are temporarily made of no material at present. It is necessary to develop a colored transparent particle for ceramics to fill the gap of marble transparent particles.
In conventional glazes, the addition of some low temperature transparent raw materials produces significant transparency, such as feldspar, zinc oxide, barium carbonate, strontium carbonate, dolomite, wollastonite, and the like. The raw materials play a role in eutectic in the glaze, so that the melting temperature of quartz which is refractory per se is reduced to form silicate crystals, and the transparent glaze can be formed by controlling a certain proportion to form a transparent sense.
It is considered that the transparent texture of marble is formed of transparent crystals, and it is required that the transparent texture particles are sufficiently melted and that bubbles are not generated at the time of firing. The defect that the low-temperature particles (the initial melting temperature is not more than 950 ℃) is favorable for fully melting bubbles in the sintering process is a common defect type in the low-temperature glaze, and bubbles can be generated in the blank and the particles in the sintering process. The low-temperature glass glaze has very low temperature, small viscosity and easy exhaust, but the boiling point of the melt is lower, so that particles are easily melt-blown on a green body to cause pit defects, and the attractiveness of the green brick is affected; the conventional low-temperature ceramic glaze has high viscosity after being melted, bubbles are difficult to remove, internal small bubbles or open bubbles are easy to form in particles, the glaze effect is poor, and the dirt absorption problem is easy to generate; the high-temperature ceramic glaze can resist the exhaust of a green body and reduce bubbles, but can reduce the transparency of the glaze surface, and the ideal ceramic tile decoration effect cannot be achieved.
Disclosure of Invention
The invention aims to overcome at least one defect of the prior art and provides transparent particles for ceramics and ceramic tiles thereof.
The technical scheme adopted by the invention is as follows:
in a first aspect of the invention, there is provided:
A transparent particle for ceramics, comprising: 100 parts of basic transparent raw materials and 0-10 parts of coloring agents; wherein:
The chemical composition of the basic transparent raw materials is as follows: silica 38.52-46.39%, alumina 5.36-8.69%, calcium oxide 9.57-15.84%, magnesium oxide 3.46-5.19%, sodium oxide 0.89-1.76%, potassium oxide 2.94-4.29%, barium oxide 4.03-5.99%, zinc oxide 10.51-13.08% and fluorine 4.28-5.09%.
In some examples of transparent particles for ceramics, the base transparent raw material has a raw material composition of: 30-38 parts of feldspar, 15-22 parts of quartz, 18-22 parts of dolomite, 10-13 parts of calcined zinc oxide, 4-6 parts of barium carbonate, 2-5 parts of wollastonite, 3-5 parts of kaolin and 8-12 parts of fluorite. The sources of the raw materials are wide and stable.
The particle size of the particles may be adjusted accordingly according to specific needs, and in some examples of transparent particles for ceramics, the particle size of the particles is 4 to 60 mesh. Thus, a better penetration feeling can be obtained. The particles are too small to show a visual perception of penetration. Too large particles may introduce defects into the green body.
The type of the colorant is not particularly limited, and may be a colorant commonly used in the ceramic field. In some examples of transparent particles for ceramics, the colorant is selected from at least one of cobalt black, cobalt blue, vanadium zirconium blue, zirconium yellow, iron red, orange, antimony tin ash, encapsulated red, encapsulated yellow, zirconium silicate, copper oxide, iron oxide, titanium dioxide, manganese oxide, cobalt oxide, nickel oxide, bismuth oxide, and vanadium pentoxide.
In some examples of transparent particles for ceramics, the preparation method comprises:
weighing raw materials according to the composition of transparent particles for ceramics, and uniformly mixing;
adding the blank reinforcing agent solution, stirring to obtain semi-moist mixture, granulating, and drying.
In some examples of transparent particles for ceramics, the onset temperature of the transparent particles for ceramics does not exceed 950 ℃. This ensures complete melting during firing.
In a second aspect of the invention, there is provided:
a ceramic tile comprising a green body having positioned on a surface thereof transparent ceramic particles according to the first aspect of the present invention.
In some examples of tiles, the method of making comprises:
Positioning transparent particles for ceramics on the surface of a green body, and pressing and forming the transparent particles and the green body together;
Further glazing or not glazing, sintering, full polishing, half polishing, matt polishing or not polishing to obtain the finished ceramic tile.
In some tile examples, the firing temperature is 1150-1230 ℃.

Example S1:
Pouring the blank powder into a ceramic tile mold, performing first pre-pressing molding, and then applying S1 colored transparent particle digital positioning cloth on the surface of the pre-pressed molded blank body through a digital cloth machine, performing second pressing molding, sintering and polishing.
The colored transparent particles on the surface of the ceramic tile are melted into transparent sky blue crystals in the firing process of the kiln, and the crystals are embedded in the green body just like the blue crystal appear vividly tile, so that the spirit of the ceramic tile is added (see figure 1 for details).
Example S2:
pouring the blank powder into a ceramic tile mold, performing first pre-pressing molding, and applying S2 colored transparent particle digital positioning cloth on the surface of the pre-pressed molded blank body through a digital cloth machine, performing second pressing molding and sintering.
The colored transparent particles on the surface of the ceramic tile are melted into transparent bright yellow crystals in the firing process of the kiln, and the crystals and the green body have good combination property as natural yellow crystals, so that the ceramic tile design has more layering sense (see figure 2 for details).
Example S3:
pouring the blank powder into a ceramic tile mold, performing first pre-pressing molding, applying S3 colored transparent particle digital positioning cloth on the surface of the pre-pressed molded blank by a digital cloth machine, performing second pressing molding, spraying ink, baking and polishing by ceramic ink.
The fired ceramic tile glaze has the design of ink, and emerald (other orange raw materials react and change to form emerald large-particle crystals in gaps, if emerald is in the gaps, so that the ceramic tile is more similar to the effect of raw stone (see figure 3 for details).
Example S4:
pouring the blank powder into a ceramic tile mold, performing first pre-pressing molding, and applying S4 colored transparent particle digital positioning cloth on the surface of the pre-pressed molded blank body through a digital cloth machine, performing second pressing molding and sintering.
The white particles under the tile glaze are connected into a whole after being fired, and form a great contrast with the green body color, so that the design feel of the tile can be maximized in some dark designs, and the tile is more advanced (see figure 4 for details).
Example S5:
pouring the blank powder into a ceramic tile mold, performing first pre-pressing molding, and applying S5 colored transparent particle digital positioning cloth on the surface of the pre-pressed molded blank body through a digital cloth machine, performing second pressing molding and sintering.

Comparative example D1:
Pouring the blank powder into a ceramic tile mold, performing first pre-pressing molding, then applying D1 colored transparent particle digital positioning cloth on the surface of the pre-pressed molded blank by a digital cloth machine, performing secondary pressing molding, sintering and polishing (the process is the same as S1).
The transparent feel of the particles on the surface of the D1 ceramic tile is reduced, the gloss is obviously weakened, and the contrast with the green body is reduced in sharp contrast with S1 (see figure 6 for details).
Comparative example D2:
Pouring the blank powder into a ceramic tile mold, performing first pre-pressing molding, then applying D2 colored transparent particle digital positioning cloth on the surface of the pre-pressed molded blank by a digital cloth machine, performing secondary pressing molding, sintering and polishing (the process is the same as S1).

Pouring the blank powder into a ceramic tile mold, performing first pre-pressing molding, and then applying D3 colored transparent particle digital positioning cloth on the surface of the pre-pressed molded blank by a digital cloth machine, performing second pressing molding and sintering (the process is the same as S2).
In contrast to S2, the yellow particles in the tile blank are higher temperature, the color development is also poor, the boundaries in the blank die, and there is no sense of motion (see fig. 8 for details).
Comparative example D4:
Pouring the blank powder into a ceramic tile mold, performing first pre-pressing molding, then applying D2 colored transparent particle digital positioning cloth on the surface of the pre-pressed molded blank by a digital cloth machine, performing secondary pressing molding, sintering and polishing (the process is the same as S1).
In contrast to S1, fluorite (CaF 2) in the raw material is replaced by sodium fluoride (NaF) which is the same kind of raw material, and since sodium fluoride is soluble in water, the prepared particles are slightly dissolved with water in the green body or glaze, and the water infiltrates into the green body, so that NaF is introduced into the green body, and the green body contains soluble salt, which may deform the green body after firing, and affects the tile effect after firing, and affects the firing of the particles, and the poor bonding between the particles and the green body, and affects the tile aesthetics (see fig. 9 for details).
The above description of the present invention is further illustrated in detail and should not be taken as limiting the practice of the present invention.
