FIG. 1 is a partial cross-sectional view of a glazed tile of porcelain high whiteness of the present invention.
Wherein: whitening glaze layer 1, bottom whitening glaze layer 11, side whitening glaze layer 12, porcelain body layer 2, cover glaze layer 3.
Detailed Description
A porcelain high-whiteness glazed tile comprises a whitening glaze layer 1, a porcelain body layer 2 and a surface glaze layer 3, wherein the whitening glaze layer is positioned on the bottom surface and/or the side surface of the porcelain body layer, and the surface glaze layer is positioned on the upper surface of the porcelain body layer;
the whitening glaze layer is formed by firing whitening glaze, the porcelain body layer is formed by firing porcelain adobes, the difference between the melting temperature of the whitening glaze and the melting temperature of the porcelain adobes is less than or equal to 3 ℃, and the difference between the expansion coefficient of the whitening glaze and the expansion coefficient of the porcelain adobes is less than or equal to 3;
the whitening glaze layer is made of zirconium silicate, and the particle size of the zirconium silicate is 1.5-3 mu m.
In order to solve the problem that the surface of the glazed tile is not consistent with the color phase of the bottom surface and/or the side surface, the technical scheme is that a whitening glaze layer 1 is distributed on the bottom surface and/or the side surface of a porcelain tile blank 2, and the whitening glaze layer 1 and a cover glaze layer 3 have the same luster, transparency and texture of the glaze layer, so that the whitening glaze layer 1 and the cover glaze layer 3 in the glazed tile can be mutually baked and supported and naturally fused in the same glazed tile product.
In the prior art, the melting temperature of the overglaze of the glazed tile is generally 50-130 ℃ lower than that of the blank body, so that the overglaze is covered on the surface of the blank body in a molten glass shape under the action of high temperature and is smoothly spread to form an overglaze layer. When firing, if the surface glaze is distributed at the bottom of the green body, because the melting temperature difference between the surface glaze and the green body is large, the green body does not enter a sintering stage, the surface glaze already starts to melt, and along with the continuous forward running of the ceramic tile in the kiln furnace by the rotation of the roller rod in the roller kiln, a part of the surface glaze which is melted in advance and is in a liquid state can be continuously wound on the roller rod of the kiln furnace, so that the running direction of the ceramic tile is inclined, the ceramic tile is easy to collide with the kiln wall, and the kiln clamping accident occurs. The other part of the glaze falls off from the bottom of the green body in the firing process due to weak adhesion with the bottom of the green body and is accumulated at the bottom of the kiln, thereby influencing the operation of airflow inside the kiln and the uniformity of a temperature field inside the kiln and causing the color difference of products. Therefore, in order to ensure that the whitening glaze distributed at the bottom of the blank layer of the glazed tile is not easy to fall off in the firing process and prevent the glazed tile product from generating color difference, the technical scheme limits the melting temperature and the expansion coefficient of the whitening glaze, respectively, the difference between the melting temperature of the whitening glaze and the melting temperature of the porcelain blank layer 2 is less than or equal to 3 ℃, and the difference between the expansion coefficient of the whitening glaze and the expansion coefficient of the porcelain blank layer 2 is less than 1. It should be noted that the melting temperature of the whitening glaze refers to the highest melting temperature of the whitening glaze, the melting temperature of the green ceramic tile refers to the highest temperature of the kiln when the ceramic tile is fired, and the expansion coefficient particularly refers to the expansion coefficient from room temperature to 400 ℃ or from room temperature to 600 ℃.
Furthermore, on the premise that the whitening glaze needs to meet the melting temperature and the expansion coefficient, the technical scheme also selects and compounds the raw materials of the whitening glaze, is favorable for improving the whiteness of the glazed tile blank, and simultaneously enables the blank to be consistent with the overglaze layer in visual properties such as glossiness and the like, thereby achieving the effect that the color tone of the bottom surface is consistent with the color tone of the side surface and/or the top surface of the blank.
In the technical scheme, the whitening glaze for improving the whiteness of the glazed tile blank contains zirconium silicate.
The whiteness refers to the capability of an object to reflect light, the light is irradiated to the surface of the object to be measured to generate light reflection, the ratio of the light intensity of incident light reflected to the receiving device to the incident light intensity is compared with a standard sample, and a corresponding whiteness value is measured. When the glaze separates out the microcrystal with the refractive index different from that of the glass phase, the light can be scattered due to the difference of the refractive index, the glaze layer is devitrified, and the opacifying whitening effect is realized. These crystallites may be achieved by the addition of an opacifying agent, of which zirconium silicate is one. Zirconium silicate is used as whitening opacifier, which can generate fine zircon crystal with small crystal grain in the whitening glaze of porcelain tiles, has a refractive index of 2.40 which is higher than that of glaze glass, and can generate scattering effect on light, thereby obtaining good opaque white glaze.
Furthermore, the technical scheme controls the particle size of zirconium silicate particles to be 1.5-3 mu m, and the zirconium silicate with the particle size range is added into the whitening glaze, so that the sintering temperature of the whitening glaze is favorably improved, the zirconium silicate crystals can be effectively separated out, and the opacifying whitening effect is enhanced.
It should be noted that the whitening glaze, the overglaze and the porcelain tile blank can be prepared by the conventional formula of the existing ceramic tile, and the melting temperature and the expansion coefficient of the whitening glaze and the porcelain tile blank can be adjusted by the existing ceramic raw materials.
Further, the whitening glaze layer 1 comprises the following raw material components in parts by weight: 7-11 parts of zirconium silicate, 14-24 parts of potassium feldspar, 15-25 parts of calcined talc, 10-14 parts of calcined clay, 6-12 parts of kaolin, 6-12 parts of calcined alumina and 25-35 parts of quartz.
The addition amount of zirconium silicate in the technical scheme is 7-11 parts, when the addition amount of zirconium silicate is more than 11 parts, the improvement of the firing temperature of the whitening glaze is obvious, the whitening glaze is in a green firing state in a kiln firing state, the densification is not achieved, a plurality of bubbles and crystal boundaries exist, and the whitening glaze can be fired white; when the addition amount of the zirconium silicate is less than 7 parts, the whiteness of the whitening glaze layer is obviously reduced, and the whiteness value is not enough.
The calcined talc is clinker which is calcined at high temperature before use, loses crystal water and organic matters, and basically has no ignition loss, so that the sintering shrinkage is small, the components are basically unchanged before and after sintering, and the accurate size, flatness and no deformation of the glazed tile product can be ensured. The calcined clay refers to calcined kaolin which is also calcined at high temperature, loses crystal water and organic matters, basically has no ignition loss, and can ensure that the glazed tile product has accurate size, flatness and no deformation. The kaolin is an indispensable component in the glaze, and is beneficial to meeting the suspension property and adhesive force of the glaze. The zinc oxide has a fluxing function, can improve the glossiness of the glaze and helps the glaze to be opaque. The calcined alumina has small expansion coefficient, and the addition of the calcined alumina is beneficial to adjusting the melting temperature of the whitening glaze. Silicon in the quartz is one of the most important elements in the glaze, the silicon dioxide can easily form various complex silicates with other oxides, the melting point of the quartz in the glaze is increased when the quartz content in the glaze is increased, the glaze is made to be refractory, the fluidity of the glaze during melting is reduced, the erosion capacity of the glaze on water and chemical substances is increased, the expansion coefficient of the glaze is reduced, and the mechanical strength and hardness of the glaze are increased.
Further, Al of the potassium feldspar2O318 to 20% in terms of its content and K2The content of O is 10-12%.
In the technical scheme of the invention, Al is selected2O318 to 20% and K2The potash feldspar with the O content of 10-12% is added into the whitening glaze, so that the melting range of the potash feldspar can be widened better, the condition that blanks on the high-temperature side and blanks on the low-temperature side in a kiln deform due to the fact that the section temperature difference is large in the kiln and the blanks on the high-temperature side and the blanks on the low-temperature side shrink inconsistently in the kiln can be restrained and improved, and the effect of improving the flatness of glazed tiles is achieved.
Further, the water absorption of the whitening glaze layer 1 is greater than that of the porcelain tile blank 2, and the difference between the water absorption of the whitening glaze layer 1 and that of the porcelain tile blank 2 is greater than 0.5-1%.
The sintering degree refers to the sintering temperature, which is the temperature at which the ceramic green body reaches the state of a solid aggregate with the minimum air holes, the maximum shrinkage, the most compact product and the most excellent performance after being sintered. The water absorption of the ceramic tile can be used for representing the sintering degree of the ceramic tile, and in order to ensure that the whitening glaze layer 1 and the ceramic body layer 2 in the glazed tile can be further mutually baked and naturally fused in the same product, the technical scheme further limits the sintering degree of the glazed tile, and is beneficial to improving the associativity of the whitening glaze layer 1 and the ceramic body layer 2 in the glazed tile.
More specifically, the whitening glaze layer 1 includes a bottom surface whitening glaze layer 11 and a side surface whitening glaze layer 12, the bottom surface whitening glaze layer 11 is located on the bottom surface of the green tile body layer 2, and the side surface whitening glaze layer 12 is located on the side surface of the green tile body layer 2.
The whitening glaze layer 1 of the technical scheme comprises a bottom surface whitening glaze layer 11 and a side surface whitening glaze layer 12, wherein the bottom surface whitening glaze layer 11 is positioned on the bottom surface of the porcelain tile body layer 2, and the side surface whitening glaze layer 12 is positioned on the side surface of the porcelain tile body layer 2, so that each surface of the glazed tile is in accordance with the color phase, and the appearance effect of the glazed tile is further improved.
Further, the thickness of the bottom surface whitening glaze layer 11 is 0.1 to 0.3mm, and the thickness of the side surface whitening glaze layer 12 is 0.02 to 0.05 mm.
According to the technical scheme, the thickness of the bottom surface whitening glaze layer 11 is limited to be 0.1-0.3 mm, when the bottom surface whitening glaze layer 11 is too thin, the geometric shading at the bottom of the porcelain tile green body layer 2 cannot be completely filled, and the protective capability of the porcelain tile green body layer 2 is easily reduced; when the bottom whitening glaze layer 11 is too thick, the normal paving of the ceramic tile is easily affected, and the attractiveness of the paving of the ceramic tile is not ensured.
Furthermore, the thickness of the side surface whitening glaze layer 12 is limited to 0.02-0.05 mm, when the side surface whitening glaze layer 12 is too thin, the side surface whitening glaze layer 12 cannot completely cover the color phase of the side surface of the porcelain tile body layer 2, so that the difference between the performance indexes of the side surface of the porcelain tile body layer 2, such as whiteness, glossiness and transmittance, and the performance indexes of the glaze layer 3, such as whiteness, glossiness and transmittance, is not easy to overcome, the color phase consistency of finished glazed tiles is not ensured, when the side surface whitening glaze layer 12 is too thick, the normal paving of the tiles is easily influenced, and the attractiveness of the paved tiles is not ensured.
A preparation method of the porcelain high-whiteness glazed tile comprises the following steps:
A. adding the whitening glaze raw material into a ball mill according to the proportion to prepare the whitening glaze;
B. adding the overglaze raw materials into a ball mill according to the proportion, mixing sodium carboxymethylcellulose, sodium tripolyphosphate and water into the ball mill, and carrying out ball milling to obtain overglaze;
C. b, applying the overglaze cloth in the step B on the upper surface of the porcelain tile blank to form an overglaze layer 3;
D. b, applying the whitening glaze cloth in the step A to the bottom surface and/or the side surface of the porcelain tile blank in the step C to form a whitening glaze layer 1, wherein the bonding force of the whitening glaze is more than or equal to 0.1 MPa;
E. and D, drying and firing the ceramic tile blank in the step D to form the whitening glazed tile.
Furthermore, the technical scheme also provides a preparation method of the ceramic high-whiteness glazed tile, wherein the bonding force of the whitening glaze is controlled to be more than or equal to 0.1MPa, so that the whitening glaze is favorably prevented from falling off from the bottom or the side wall of a ceramic tile blank, the color phase consistency of a ceramic tile finished product is ensured, the deformation degree of the ceramic tile finished product is reduced, and the preparation method is simple in process and strong in operability.
The specific steps of step a may include any one of the following two types:
(1) a, adding the whitening glaze raw material into a ball mill according to a ratio, mixing sodium carboxymethylcellulose, sodium tripolyphosphate and water into the ball mill, and carrying out ball milling to obtain the whitening glaze;
the whitening glaze raw material, the grinding balls and the water are added in a mass ratio of 1:2 (1-0.8). The whitening glaze raw material is 1 part by weight, the addition amount of the sodium carboxymethyl cellulose is 0.15-0.25 part by weight, and the addition amount of the sodium tripolyphosphate is 0.2-0.35 part by weight.
(2) A, weighing whitening glaze raw materials according to a ratio to form a mixture, and then adding the mixture into a ball mill for dry ball milling; finally, mixing and stirring the mixture and the organic solvent according to the proportion to form whitening glaze; when the whitening glaze is prepared by using an organic solvent, the better adhesion can be provided, and the whitening glaze is prevented from falling off before the ceramic tile enters a kiln for firing.
In one embodiment of the technical scheme, the organic solvent comprises ethylene glycol, glycerol, polyether polyol, acrylic acid and acrylamide, and the addition ratio of the mixture, the ethylene glycol, the glycerol, the polyether polyol, the acrylic acid and the acrylamide is (7-30): (40-50): (20-30): (15-25): (5-10): (5-10).
It should be noted that the porcelain tile body and the overglaze can be made by the existing formula.
Further, in the step A, the whitening glaze is sieved by a 325-mesh sieve, the screen residue is 2-3%, and the ball yield of the whitening glaze is more than or equal to 1.88.
The finer the fineness of the whitening glaze, the better the suspensibility and fluidity, but if the fineness of the whitening glaze is too coarse, the roughness of the fired whitening glaze surface is easily caused. Furthermore, the technical scheme limits the ball-out specific gravity of the whitening glaze to be more than or equal to 1.88, and facilitates on-site glaze adjustment.
More specifically, step D further includes the following steps:
d1, applying the whitening glaze in the step A to the bottom surface of the porcelain tile blank in the step C in a spraying or roll coating glazing mode to form a bottom surface whitening glaze layer 11;
d2, spreading the whitening glaze in the step A on the side surface of the porcelain tile blank in the step D1 by a brushing glazing mode to form a side whitening glaze layer 12.
The whitening glaze layer positioned on the bottom surface is applied by a spraying or rolling glazing mode, so that the whitening glaze layer with a certain thickness is formed at the bottom of the body layer, and the function of the whitening glaze layer can be effectively realized.
The whitening glaze layer on the side surface is applied in a brushing glazing mode, so that a thin-walled whitening glaze layer is formed on the side part of the body layer, the function of the whitening glaze layer is realized, and the influence of the side surface whitening glaze layer on the paving of the glazed tile is effectively avoided.
Further, in an embodiment of the present technical solution, the glazed tile axis application sequence is:
firstly, coating surface glaze on the upper surface of a porcelain tile blank;
then, spraying whitening glaze on the bottom surface of the porcelain tile blank;
and finally, arranging brushing shafts at the two advancing sides of the ceramic tile body, brushing whitening glaze, clamping the two side surfaces of the ceramic tile body without the brushing shafts, rotating the two side surfaces by 90 degrees, and feeding the ceramic tile body into a kiln after the two side surfaces are glazed.
It should be noted that, because the difference between the melting temperature of the whitening glaze and the melting temperature of the porcelain tile blank 2 is less than or equal to 3 ℃, and the difference between the expansion coefficient of the whitening glaze and the expansion coefficient of the porcelain tile blank 2 is less than or equal to 3, the whitening glaze cannot be separated from the bottom of the porcelain tile blank in the process of firing the glazed tile.
Further, since the whitening glaze in the present technical solution is in direct contact with the roller bar in the kiln, the whitening glaze inevitably sticks to the roller bar, but only a small amount of the whitening glaze sticks to the roller bar, and since the whitening glaze of the present technical solution does not carry a decoration function, the effect can be ignored.
Preferably, the technical scheme can also apply back primer on the bottom surface of the bottom surface whitening glaze layer 11, and the back primer is favorable for preventing the whitening glaze positioned on the bottom surface from being adhered to the roller rod of the kiln.
Preferably, step D1 is preceded by step D0:
d0, adjusting the specific gravity of the whitening glaze in the step A to ensure that the specific gravity of the whitening glaze for spraying is 1.35-1.40, the specific gravity of the whitening glaze for roller coating is 1.60-1.80, and the specific gravity of the whitening glaze for brush coating is 1.64-1.82.
The proportion of the whitening glaze is adjusted according to different glazing modes, which is beneficial to ensuring the glazing effectiveness of the whitening glaze, thereby ensuring that the whitening glaze has a protective effect on the green bricks.
The spraying glazing is to spray glaze slurry into mist with compressed air and blow the mist onto green brick, so that the glaze is adhered to the green brick. The spraying glazing requires the glaze slip to have large water content and small concentration, so the specific gravity is between 1.35 and 1.40. The spraying specific gravity is more than 1.40, the spray gun is easy to block by the glaze slurry, the spraying specific gravity is less than 1.35, and the quantity of the glaze slurry sprayed to the green brick is too small and too thin.
The roller-coating glazing is that a cylindrical rubber roller is arranged above a glaze groove, the glaze groove is filled with whitening glaze slurry, the glaze groove is relatively vertical to a glazing line, the glaze groove is arranged below the glazing line, when a brick blank moves forwards on the glazing line, the rubber roller on the glaze groove starts to rotate, and the whitening glaze slurry adhered on the rubber roller is distributed at the bottom of the brick blank along with the rotation of the rubber roller and the advancing of the brick blank.
When the roller is used for roller coating the whitening glaze, the specific gravity is less than 1.60, the concentration of the glaze slip is low, the adhesion force of the glaze slip and the roller is low, the glaze slip adhered to the roller is less, the whitening glaze coated on the green brick is less, the thickness is thinner, and the bottom of the green brick cannot be well filled. When the roller is used for roller coating whitening glaze, the specific gravity is more than 1.80, the concentration of glaze slip is high, the adhesion of the glaze slip and the roller is high, the number of the glaze slips adhered to the roller is large, the whitening glaze coated on a brick blank is large, the thickness is thicker, and the bottom glaze of the brick blank is too much.
Because the glazing part is arranged on the side surface of the blank body, the glazing mode of brushing the side surface of the blank body is mostly manual glazing, and the specific gravity of the whitening glaze for brushing is limited to 1.64-1.82 in the technical scheme. When the specific gravity of the whitening glaze is less than 1.64, the glaze slurry has large water content, the side surface water absorption area of the blank body is small, the surface drying rate after glazing is slow, and the method is not suitable for the subsequent working procedure operation; when the proportion of the whitening glaze is more than 1.82, the concentration of the glaze slurry is high, the continuous brushing operation of the side surface of the blank body is inconvenient, and the brushing of the glaze layer on the side surface is not uniform.
Furthermore, when the bottom surface of the green brick is glazed by using a roller-coating glazing method to form a bottom surface whitening glaze layer 11, the glazing thickness is 0.3-0.7 mm; when the bottom surface of the green brick is glazed by a spraying glazing mode to form a bottom surface whitening glaze layer 11, the glazing thickness is 0.18-0.35 mm; when the side surface of the green brick is glazed by using a brushing glazing mode to form the side surface whitening glaze layer 12, the glazing thickness is 0.02-0.05 mm.
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
Example group 1-a method for preparing a glazed tile of porcelain high whiteness, comprising the following steps:
A. adding the whitening glaze raw materials in the proportion of the following table 1 into a ball mill, mixing sodium carboxymethylcellulose, sodium tripolyphosphate and water into the ball mill, and carrying out ball milling to obtain the whitening glaze;
B. adding the overglaze raw material into a ball mill according to the proportion, mixing sodium carboxymethylcellulose, sodium tripolyphosphate and water into the ball mill, and carrying out ball milling to obtain overglaze, wherein the overglaze is prepared from a conventional overglaze formula of the glazed tile;
C. b, applying the overglaze cloth in the step B on the upper surface of the porcelain tile blank to form an overglaze layer;
