Description
Technical Field
The invention relates to the technical field of ceramic rock plates, in particular to a micro-gloss glaze material for precipitation microcrystals, a micro-gloss ceramic rock plate with an ultra-flat fine glaze surface and a preparation method thereof.
Background
As a novel material, the ceramic rock plate has physical properties obviously superior to those of the traditional ceramic tiles, and has an increasing share in the ceramic market. The technical effects of the rock plate surface mainly comprise from the luster point of view: three kinds of light, soft light and matte. The bright light is the mirror surface effect with the brightness of more than 50 degrees after polishing, wherein the glossiness is relatively bright; soft light refers to a mirror effect with a gloss of about 15-30 degrees after polishing; matte is generally defined as a photometric texture with a gloss level of less than 15 degrees and even zero degrees. With the emergence of new generation consumers, the demand for matte products is continuously rising, and the matte texture is higher and resistant to seeing, so that the requirements of young consumers are met.
At present, a matte glaze is generally adopted for a ceramic rock plate to realize a matte effect, for example, anorthite glaze is adopted, a large amount of fine crystals are precipitated in a glaze glass body, the fine crystals are uniformly distributed from the surface of a glaze layer to the inside, the surface of the glaze layer is uneven and is observed in an SEM scanning electron microscope image to be in a wavy state, the specular reflection of incident light is weakened, the diffuse reflection is enhanced, and the precipitated fine crystals are mainly anorthite crystals and albite crystals. Although the matte glaze can realize a matte effect, the proportion of the glaze with more phases and less crystal phases in the internal microstructure is unreasonable, and the matte glaze is characterized by planeness deviation in a macroscopic sense, so that ultra-flat and fine particle touch feeling is not achieved.
Accordingly, the prior art is still in need of improvement and development.

In some embodiments, a method for preparing a micro-gloss ceramic rock plate with ultra-flat fine glaze is also provided, which comprises the steps of: preparing a green body layer; applying a primer layer on the green body layer; ink-jet printing a pattern layer on the primer layer; the pattern layer is coated with a dry grain glaze layer and then is subjected to firing treatment to prepare initial ceramic; and brushing and polishing the initial ceramic to obtain the micro-gloss ceramic rock plate with the ultra-flat fine glaze. The preparation method of the micro-gloss ceramic rock plate provided by the invention has the advantages of simple process and easiness in operation.
In the invention, the material for preparing the dry grain glaze layer is a micro-gloss glaze, the micro-gloss glaze comprises transparent protective glaze slurry, dry grain powder and suspending agent, the dry grain powder is formed by crushing and sieving high-calcium high-barium high-strontium frit, a large amount of calcium oxide, barium oxide and strontium oxide are introduced into the dry grain powder to play a fluxing role on the glaze, the firing temperature can be reduced, a large amount of microcrystals are formed on the basis of the ground glaze layer of a high-temperature system, the microcrystals extend from the glaze surface layer to the inside and are uniformly distributed, the surface of the glaze is uneven from the microcosmic part, the specular reflection of incident light is effectively weakened, the diffuse reflection is enhanced, and the micro-light effect is formed; macroscopically, the glaze is fine and smooth and granular, and the glaze with ultra-flat fine and smooth fine and granular touch feeling is formed after brushing and polishing. The glossiness of the prepared micro-gloss ceramic rock plate is between 10 and 15 ℃, and the surface of the micro-gloss ceramic rock plate has ultra-flat and fine particle touch feeling.
In the invention, the purpose of applying the base glaze is to cover the base color and flaws of a green body layer, increase the whiteness of the glaze surface, be favorable for the color development of the subsequent ink-jet printing pattern, and the glazing weight is too small to reach the effect of covering the base color, be unfavorable for the color development of the subsequent ink-jet printing pattern, the too high glazing weight can cause the glaze layer to be too thick, the glaze slurry flows to the edge, not only causes waste, but also causes the glaze slurry to flow into a kiln roller in the firing process, and the roller nails are formed in a cumulative period to cause kiln blockage. Based on the above, in the process of applying the primer layer on the blank layer, the glazing specific gravity of the primer layer is 1.85-1.95g/ml, the glazing flow rate of the glazing slurry is 30-40 seconds, and the glazing weight is 470-560g/m 2.
In the invention, too little glazing weight of a plurality of glaze layers can lead to rough surface and cannot obtain fine and smooth low-light effect; if the glazing weight is too much, the surface glossiness is larger, the texture is worse, so the glazing weight is set to be in a preferable range of 280-380g/m 2, and the glazing specific gravity of the dry grain glaze layer is as follows: 1.35-1.45g/ml. In the invention, the surface particles are obvious due to the fact that the number of the powder particles is too large (the particle size is too large), and the texture of the powder particles is not smooth and fine; the particle size of the dry powder is too small (the particle size is too small) which leads to a brighter surface texture, and the cost of the dry powder is also increased sharply, so the particle size of the dry powder is set to be in a preferable range of 250-300 meshes.
In the step of brushing and polishing the initial ceramic, the invention preferably uses the 80-mesh silicon carbide fiber abrasive blocks to brush and polish the initial ceramic in 4-8 groups, thereby obtaining better smooth effect, not increasing gloss and meeting the qualification of antifouling property.
In the step of firing treatment after the dry grain glaze layer is distributed on the pattern layer, the firing temperature is 1190-1220 ℃ and the firing time is 60-90min. In the firing temperature and time range, a large number of fine barium strontium feldspar and potassium sodium feldspar crystals are precipitated in the glaze glass body, extend from the glaze surface layer to the inside and are uniformly distributed, and the microcrystals have strong diffuse reflection effect on light, so that the glaze surface of the micro-gloss ceramic rock plate has a stable micro-gloss effect.
