Detailed Description
The technical solution of the present invention is further explained by the following embodiments.
The invention provides a high-stain-resistance FFC glaze which comprises the following raw materials in parts by weight:
22-29 parts of quartz, 24-28 parts of potassium feldspar, 6-10 parts of wollastonite, 7-8 parts of zirconium silicate, 5-10 parts of kaolin, 0-5 parts of calcite, 5-7 parts of zinc oxide, 5-7 parts of alumina, 2-3 parts of frit, 4-8 parts of dolomite, 5-8 parts of calcined talc, 1-4 parts of barium carbonate and 0.2-0.5 part of sodium carboxymethylcellulose.
FFC is an abbreviation for Fine Fire Clay, a material used to make ceramics. The FFC slurry can be used for preparing a green body of the sanitary ceramic through high-pressure grouting. The FFC blank has poor thermal stability and is easy to deform at high temperature, most of the conventional sanitary ceramic glaze materials contain low-temperature materials such as high-sodium stone powder, potash-sodium feldspar and the like, and the high-temperature resistance is low, so that the glaze layer on the surface of the sanitary ceramic has glaze defects such as tiny pinholes, unevenness, microcracks and the like which cannot be seen by naked eyes.
Quartz is adopted as silicon dioxide (SiO) in the high-anti-pollution FFC glaze2) The principal donor of the component, Silica (SiO)2) Is the main component forming the glazed glass phase. Wollastonite is likewise silicon dioxide (SiO)2) The main raw materials for providing the components, potassium feldspar, albite and kaolin, are alumina (Al)2O3) Composition, and providing a minor portion of silicon dioxide (SiO)2）。
The Si/Al mass ratio of the glaze can be effectively reduced by adjusting the use amounts of kaolin, potassium feldspar, albite and wollastonite, the glaze melting temperature is directly influenced, the viscosity of the glaze in a melting state is improved, the glaze slip can be fixed on a blank body and is not easy to flow away, and the surface defects of the glaze are reduced. In addition, under high temperature, the melt with higher viscosity can continue to melt, and the breaking of bubbles generated in the melting process can play a role of stirring, so that the glaze is melted more uniformly, and the purpose of further reducing surface defects is achieved.
The high anti-fouling FFC glaze material utilizes the polybase effect, reduces the network strong destruction body sodium ions by introducing barium carbonate and increasing the using amount of burning talc and reducing the using amount of albite, improves the burning temperature range, enables the blank body to exhaust more smoothly, and reduces the porosity of the glaze surface; and barium carbonate has the effect of reducing pores and bubbles. In addition, the FFC glaze material with high anti-fouling capability utilizes the similar intermiscibility principle, increases the dosage of alumina and quartz, improves the binding property of blank glaze, and relatively further reduces the microcracks of the glaze surface.
The crystal chemical formula of the kaolin is 2SiO2·Al2O3·2H2And O, kaolin mainly improves the melting temperature of the glaze and the suspension property of the glaze, so that the glaze slip is not easy to precipitate.
The zirconium silicate has good chemical stability and is not influenced by the firing atmosphere of the ceramic, and the zirconium silicate mainly plays the roles of an opacifier and a whitening agent. In addition, the zirconium silicate is added into the formula system, and can obviously improve the separation performance of the blank glaze of the ceramic, so that the ceramic glaze surface is more attached to the blank body, and the blank body is prevented from slightly deforming and separating from the glaze surface to form fine cracks.
Calcite and dolomite mainly play a role in fluxing in a formula system, wherein the main chemical component of the dolomite is CaMg (CO)3)2The main chemical component of calcite is CaCO3. By regulating the content of calcium and magnesium and the proportion of the network body and the network intermediate, the optimal fluxing effect can be obtained, so that the glaze has higher high-temperature viscosity and higher high-temperature fluidity.
The zinc oxide mainly plays a role in fluxing in a formula system, is matched with calcite and dolomite for use, plays a larger role in improving the glossiness of a glaze surface, can increase the mechanical elasticity of the glaze and the strength of the glaze within a certain range, has unobvious functions of increasing the mechanical elasticity of the glaze and the strength of the glaze when the content of the zinc oxide is less than 2 percent, and easily causes the phenomenon of low temperature and even crystallization of the glaze surface when the content of the zinc oxide is more than 5 percent.
The sodium carboxymethyl cellulose is used as a binder and added into a formula system of the FFC glaze with high antifouling capacity, so that the adhesion capacity of the glaze can be improved, the breakage rate of a dried blank body is reduced, and the adhesion force of the glaze and the strength of a glaze layer are enhanced.
Preferably, the high-stain-resistance FFC glaze further comprises 0-3 parts by weight of albite. Albite is also mainly used for increasing the content of alumina in glaze ingredients and has a fluxing function, but the albite contains sodium oxide which is a strong network disrupter and can break a glass network, so that the high-antifouling FFC glaze reduces the using amount of the albite.
Specifically, the mass ratio of Si/Al is SiO in the glaze2With Al2O3The mass ratio of (a). The mass ratio of Si to Al in the FFC glaze material with high anti-fouling capacity is (5.65-6.19): (1.15-1.48); the mass percentage content of sodium oxide in the high anti-fouling FFC glaze is 1.10-1.34%; the mass ratio of calcium oxide to magnesium oxide in the high-antifouling-capacity FFC glaze is (5.40-6.60): (2.98-3.69).
Specifically, the content of potassium oxide in the potassium feldspar is greater than or equal to 10%; the content of sodium oxide in the albite is greater than or equal to 7%; the burned talc has a magnesium oxide content of greater than or equal to 30%. The potassium feldspar is mainly used for improving the content of aluminum oxide in the glaze material, is provided with potassium oxide, and can reduce the melting temperature and increase the content of alkali so as to reduce the consumption of the alkali and increase the viscosity of the glaze material in a melting state. The calcined talc is mainly used for providing magnesium oxide, and is matched with calcite for use to achieve the purpose of regulating the content of calcium and magnesium, so that the proportion of the network body and the network intermediate is controlled, and the glaze has high-temperature viscosity and high-temperature fluidity.
Therefore, the content of potassium oxide in the potassium feldspar, the content of sodium oxide in the albite and the content of magnesium oxide in the calcined talc influence the high-temperature viscosity and the high-temperature fluidity of the glaze material, and further influence the compactness of the sanitary ceramic glaze surface. If the content of potassium oxide in the potassium feldspar, the content of sodium oxide in the albite or the content of magnesium oxide in the burnt talc is lower than expected, the use amount of the potassium feldspar, the albite or the burnt talc is increased, the Si/Al mass ratio of the glaze is changed, the mass ratio between the magnesium oxide and the calcium oxide is difficult to control, and the glaze cannot obtain expected physical properties. In order to regulate and control the Si/Al mass ratio, the content of sodium oxide and the proportion of calcium oxide and magnesium oxide in the formula, the content of potassium oxide in the potassium feldspar should be more than or equal to 10 percent, and the content of sodium oxide in the albite should be more than or equal to 7 percent; the content of magnesium oxide in the calcined talc should be greater than or equal to 30%.
Preferably, the weight of zirconium silicate having a particle size below 5 μm among the zirconium silicates is more than 80% of the total zirconium silicate weight. The particle size of the zirconium silicate is less than 5 mu m, which is beneficial to improving the flatness, the fineness and the glossiness of a glaze surface, reducing the number of pinholes, shortening the ball milling time and improving the ball milling efficiency.
Specifically, the frit is a zinc-free opaque frit, and the zinc-free opaque frit comprises the following components in parts by weight: 66% SiO2、4%Al2O3、8%CaO、12%Na2O、1.0%MgO、7.8%B2O3. The frit plays a role of a flux, and the zinc-free opaque frit is preferably selected in the technical scheme, so that the glaze quality can be effectively improved due to high initial melting temperature, wide application range, high blank glaze binding degree and good glossiness after firing, but the use amount needs to be controlled, and if the use amount is too much, the glaze is easy to have the defects of pinholes and the like.
The invention also provides a preparation method of the FFC sanitary ceramic with the high anti-fouling FFC glaze, which comprises the following steps:
pre-ball milling of frits: weighing the frits according to the proportion, and performing ball milling treatment on the frits according to the formula amount in advance;

In addition, the glaze slip passes through a 160-200-mesh sieve and is deironized, the glaze slip is subjected to impurity removal and particle size distribution optimization, the density of the glaze surface can be effectively improved, and the problem of glaze surface defects such as tiny pinholes, concave-convex, microcracks and the like on the glaze layer is further reduced. The glaze slip is obtained by mixing glaze and water and then performing a ball milling step.
Further, in the ball milling step, the chemical components of the glaze slip comprise the following components in percentage by mass:
56.5～61.9%SiO2、11.5～14.8%Al2O3、5.0～7.0%CaO、4.8～5.6%ZrO2、4.0～6.0%ZnO、2.0～3.5%K2O、0.5～1.5%Na2O、2.8～4.0%MgO、0.1～0.2%B2O30.77-2.0% BaO and 4.0-7.5% I.L.

The mass ratio of Si to Al in the glaze slip is (5.65-6.19): (1.15-1.48), and the content of sodium oxide is only 1.10-1.34%, so that the damage to a glass network structure is reduced, the bonding property of blank glaze is improved, the thermal expansion coefficient of a blank body subjected to high-pressure grouting is matched with that of the glaze, and the microcracks of the glaze are reduced; in addition, the high mass ratio of Si to Al also improves the sintering temperature range, reduces the porosity of the glaze surface, improves the smoothness of the glaze surface and improves the melting homogenization degree of the glaze material.
In addition, the mass ratio of CaO to MgO is limited to (5.40-6.60): (2.98 ~ 3.69), when making the frit possess higher high temperature viscosity, have higher high temperature mobility again to make the frit can adapt to the ceramic body of high-pressure slip casting, can effectively improve the glaze reaction density of high-pressure slip casting ceramic body, then reduce the glaze layer and appear the problem of glaze defects such as tiny pinhole, unsmooth and microcrack.

in example 7, the mass ratio of Si/Al was 6.79:1.15, the content of sodium oxide was 1.30%, and the mass ratio of calcium oxide to magnesium oxide was 8.98: 3.13.
As can be seen from table 2, in the embodiments 1 to 5, the FFC glaze with high anti-fouling capability is prepared by using the formula content in the technical scheme, so that the sanitary ceramic plate prepared by using the FFC glaze with high anti-fouling capability has good appearance flatness, the glaze surface is smooth and compact, the number of the dirt suction points in the dirt suction test is 8 to 21, the glossiness reaches the range of 110 to 115GU, and the purposes of reducing the defects of the glaze surface, preventing the attachment of pollutants and improving the glossiness are achieved.
By comparing the examples 6 and 7 with other examples, it can be seen that when the content of the raw material components exceeds the range defined in the technical scheme, the sanitary ceramic plate prepared by using the high anti-fouling FFC glaze material has different loss of appearance flatness and glossiness, and the glaze surface defect is increased, so that the prepared sanitary ceramic plate can not reach the standard required by production.
Example 8
The mixture ratio of the raw materials of the high anti-fouling FFC glaze in example 8 is the same as that in example 1, in the sanitary ceramic process of preparing the high anti-fouling FFC glaze by using the high anti-fouling FFC glaze in example 8, the step of pre-ball milling of the frits is omitted, and other steps are the same as those in example 1. And (3) testing results: gloss 108, number of dirt pickup points 23.
Comparative example group B
The preparation method of the sanitary ceramic using the high anti-fouling FFC glaze is consistent with examples 1-3 in example group A, and the raw material ratio of comparative examples 1-3 is shown in Table 3.
Figure 641894DEST_PATH_IMAGE003
The frit comprises the following components in parts by weight: 66% SiO2、4%Al2O3、8%CaO、12%Na2O、1.0%MgO、7.8%B2O3. The content of potassium oxide in the potassium feldspar is 10 percent; the content of sodium oxide in the albite is 7 percent; the content of magnesium oxide in the calcined talc was 30%.
The FFC glaze with high antifouling capacity and different raw material formulas in the table 3 and the preparation method are respectively used for preparing the sanitary ceramic plate, and the sanitary ceramic plate and an industrial sanitary ceramic sample plate are subjected to a pollution absorption test and a glossiness test.
The method for testing the dirt absorption test comprises the following steps: smearing red ink or blue ink on a 10 x 10cm sanitary ceramic plate, smearing the ceramic plate for 3-5 minutes by using a rubber glove, washing the ceramic plate by using clear water after the ink is dried in the shade, wiping the ceramic plate dry, and checking the number of dirt-absorbing points in a bright place.
The results are shown in table 4 below:
Figure 189550DEST_PATH_IMAGE004
in comparative example 1, the mass ratio of Si to Al was 5.92:1.06, the content of sodium oxide was 1.58%, and the mass ratio of calcium oxide to magnesium oxide was 8.29: 1.88;
in comparative example 2, the mass ratio of Si/Al was 6.61:1.33, the content of sodium oxide was 1.89%, and the mass ratio of calcium oxide to magnesium oxide was 7.45: 2.67;
in comparative example 3, the Si/Al mass ratio was 5.56:1.29, the sodium oxide content was 1.23%, and the mass ratio of calcium oxide to magnesium oxide was 10.67: 2.7.
As can be seen from Table 4, in comparative example 1, the albite usage amount is increased, the usage amounts of aluminum oxide and calcined talc are reduced, barium carbonate is not added, the proportion of calcium oxide is large, and the proportion of magnesium oxide is small, so that the sanitary ceramic plate prepared from the FFC glaze with high stain resistance is poor in appearance flatness, more stain absorption points are used in a stain absorption test, and the glossiness does not reach the sizes of examples 1-5.
In the comparative example 2, the albite consumption is increased, so that the sanitary ceramic plate prepared by the high-antifouling-capacity FFC glaze is poor in appearance flatness, more in number of dirt-absorbing points in a dirt-absorbing test, and poor in glossiness which cannot reach the sizes of the examples 1-5.
In the comparative example 3, the use amounts of calcite and dolomite are changed, and the proportion of calcium oxide and magnesium oxide is changed, so that the sanitary ceramic plate prepared from the high-antifouling-capacity FFC glaze is poor in appearance flatness, more in number of dirt-absorbing points in a dirt-absorbing test, and the glossiness of the sanitary ceramic plate cannot reach the sizes of the examples 1-5.
