More preferably, the sanitary ceramic glaze with the three-dimensional glittering effect comprises, by mass, 25.9 parts of red lead, 7.7 parts of quartz, 36.8 parts of feldspar and 3.4 parts of K2CO38.9 parts of Na2CO37.3 parts of limestone, 10 parts of frit, 10 parts of mica powder and 0.15 part of CMC (sodium carboxymethylcellulose).
More preferably, the sanitary ceramic glaze with the three-dimensional glittering effect comprises, by mass, 24.5 parts of red lead, 7.4 parts of quartz, 37.7 parts of feldspar and 4.0 parts of K2CO39.1 parts of Na2CO37.8 parts of limestone, 9.5 parts of frit, 10 parts of mica powder and 0.15 part of CMC (sodium carboxymethylcellulose).
In the invention, the frit is a low-temperature frit, and the initial melting temperature is 650-750 ℃, preferably 700 ℃; the temperature at which the water absorption is zero is 800-900 deg.C, preferably 850 deg.C.
The invention also adopts the technical scheme that:
a preparation method of a sanitary ceramic glaze with a three-dimensional glittering effect comprises the following steps:
1) respectively putting the raw materials except mica powder into a ceramic ball mill for ball milling, adding the mica powder material when the granularity reaches below 10 mu m and accounts for 60-68%, continuing ball milling until the granularity reaches below 10 mu m and accounts for 69-75%, and finishing ball milling to prepare glaze slurry;
2) the glaze slip material is refined, and the performance of the glaze slip material can reach: the concentration is 350 +/-10 g/200mL, the pulp temperature is 25 +/-3 ℃, and the viscosity is V0The slurry is 80 +/-5 s/100mL, and the yield value is 10 +/-4;
3) spraying the sanitary ceramic glaze on the surface of the sanitary ceramic, and firing and discharging the sanitary ceramic glaze from a kiln at the temperature of 850 ℃ and 900 ℃ for 15-17 hours to obtain the sanitary ceramic product with the three-dimensional flickering effect.
In one embodiment, the refining process in step 2) is: firstly, screening glaze slip, wherein the glaze slip is filtered by a 180-mesh screen; the second step, adjusting the water content in the glaze slip to ensure the reasonable physical property, wherein the concentration of the slip is 350 +/-10 g/200mL, and the viscosity is V0Is 80 plus or minus 5s/100 mL; thirdly, carrying out iron removal treatment on the glaze slurry by using an iron removing rod (or an iron remover) for the sanitary ceramics; and fourthly, stirring the glaze slip by using a stirrer to ensure the uniformity of the glaze slip and further ensure the stability of the product. .
In the present invention, the effect of the red lead: the melting point of the lead can be as low as 500 ℃, so that the sintering temperature and the initial melting temperature of the glaze slip can be reduced, and the effective effect of the mica powder (the main component for generating the three-dimensional scintillation effect) after the porcelain is formed is ensured. If the adding amount of the red lead is too small and is less than 22.0 parts, the initial melting temperature of the glaze slurry is too high, and the glaze surface flows at a high temperature to generate glaze surface defects; if the using amount is too large and is more than 28.0 parts, the initial melting temperature and the melting temperature of the glaze slip are too high, and the glaze surface is not well-burned.
In the invention, quartz is used for improving the high-temperature viscosity of the glaze slip, reducing the thermal expansion coefficient of the glaze slip, increasing the chemical stability of the glaze slip, and simultaneously endowing the glaze slip with the advantages of higher hardness, wear resistance, corrosion resistance, atmospheric efflorescence resistance and the like. If the quartz addition amount is too small and less than 6.0 parts, the hardness, wear resistance and corrosion resistance of the glaze are deteriorated; if the amount is too large, more than 8.0 parts, excessive undissolved quartz particles will be present in the glaze at high temperature, and the hardness of the glaze surface will be reduced.
K2CO3、Na2CO3Limestone can be attributed to cosolvents, has a strong fluxing effect, and has a certain effect on optimizing the refractive index, glossiness, hydrolysis resistance, corrosion resistance and thermal stability of the glaze; if the addition amount is too small, the whole glaze slip cannot be melted; if the using amount is too large, the fluxing effect is too obvious, and the glaze slip cannot be adsorbed on the surface of the blank body, so that the defect of 'glaze flowing' is caused.
The cross section of the high-temperature mica powder has a physical structure close to that of the pearl; the inner core is a low optical index mica and the outer layer is a higher index metal oxide. In the ceramic glaze, high-temperature mica powder is uniformly dispersed in the coating and is distributed in a multilayer manner in parallel to the surface of a substance, and incident light can reflect a three-dimensional scintillation effect through multiple reflections as in pearls. If the addition amount is too small, the glaze slip can dissolve part of mica powder, so that the glaze surface can not present a flash effect; if the using amount is too large, the bonding force between the glaze surface and the blank body is reduced, so that the surface glaze of the product at the later stage is easy to crack.
Fusion cakes: can be used for adjusting the temperature of glaze slip and improving the binding force of mica powder. If the addition amount is too small, the melting temperature of the glaze slurry is increased, the binding force between mica powder and a blank is poor, and the surface glaze of a product at the later stage is easy to crack; if the amount of the mica powder is too large, the melting temperature of the glaze slip is reduced, and the glaze slip can dissolve part of the mica powder, so that the glaze cannot show a glittering effect.
The invention has the following advantages: the ceramic glaze prepared by the invention has golden yellow metal texture, meanwhile, the surface has a flickering effect, and meanwhile, the ceramic glaze has low water absorption (less than 0.2%) and good crack resistance; the roughness is good, no obvious color difference exists, and the obtained product has the color value range as follows: l: 50-70, A: 5-15; b: 30-40. The sanitary ceramic prepared from the glaze is particularly suitable for being applied to places such as tourist attractions, high-end hotels, villas and the like.
