Description
Technical Field
The invention relates to the field of architectural ceramics, in particular to a wear-resistant glaze material, a preparation method thereof and a glazed tile using the same.
Background
The abrasion resistance of the glaze is a great problem in the industry at present. When the glass ceramic composite board is used as a ground decoration material, the glass ceramic composite board has a higher requirement on the wear resistance of the glaze, otherwise, the glass ceramic composite board is easy to grind, and although the glass ceramic composite board is greatly improved compared with the existing glass ceramic composite board, the wear resistance of the existing glaze cannot meet the requirement.
In the prior art, the following two solutions are mainly used for solving the wear resistance of the glaze: first, this problem is being solved with the mode of thickening glaze layer to the manufacturing enterprise of some ceramic tiles, nevertheless along with the glaze layer thickening, the product that has the stamp layer to adobe surface has certain influence, simultaneously along with the glaze layer thickening, also increase manufacturing cost, and because it need throw the mill, some confined bubbles that exist can present at throwing the mill process in the thick glaze layer, cause the influence to the outward appearance effect and the antifouling performance of final products, and the poor problem of glaze wear resistance can only be alleviated to the mode on this kind of thickening glaze layer in addition. Secondly, at present, the abrasion resistance of the glaze can be improved by adding abrasion-resistant media such as corundum and the like into the glaze, when the addition amount of corundum is small, the glaze cannot play a role in improving the abrasion resistance, and when the addition amount of corundum is large, glaze defects such as rough glaze, whitening, chromatic aberration, many pores and the like are easy to occur, so that the antifouling performance of the glaze is also poor. However, when corundum is added into glaze, glaze is easy to opal, or the addition amount is very limited because the temperature of the glaze is increased by a substance with high refractoriness, so that the wear resistance of the glaze is difficult to control.
Although the two solutions can increase the wear resistance of the glaze to a certain extent, the antifouling property is reduced, and the two solutions cannot be well utilized by other ceramic tile production enterprises.

Detailed Description
A wear-resistant glaze material which comprises a mixture of calcium carbonate, calcined talc, clinker and kaolin, and which does not contain corundum and feldspar.
In order to improve the wear resistance of the wear-resistant glaze, the technical scheme of the invention ensures that anorthite, cordierite and mullite are separated out from the glaze layer as main crystal phases to improve the wear resistance of the glaze by adjusting the raw materials and the proportion of the wear-resistant glaze. Specifically, the raw materials of the wear-resistant glaze provided by the technical scheme comprise a mixture containing calcium carbonate, calcined talc and kaolin.
The technical scheme uses the calcium carbonate, on one hand, the calcium carbonate can provide CaO required by anorthite crystallization, so that anorthite crystals are separated out from a glaze layer to improve the wear resistance of the glaze; on the other hand, the addition of the calcium carbonate is beneficial to the full exhaust of the glaze in the firing process, effectively avoids no closed air bubbles in the glaze layer, and can prevent the defects of pinholes and the like in the fired glaze surface caused by the exhaust problem.
The burning talc exists not only in a liquid phase in the firing process of the glaze, but also can provide MgO required by the burning talc for cordierite crystallization in the firing process of the glaze, so that the glass phase of a glaze layer is reduced and the crystallization amount is increased after the glaze is fired and cooled, thereby being beneficial to improving the wear resistance of the glaze.
The kaolin mixture is easy to disperse in water and difficult to precipitate, has better suspension property and viscosity, and can ensure the suspension property and viscosity of the glaze slip by introducing the kaolin mixture into the formula. Meanwhile, the main component of the kaolin mixture is SiO2·AL2O3The mullite ceramic glaze is a main raw material for separating mullite crystals from a glaze layer in the firing process of the glaze, so that the introduction of kaolin and calcined kaolin into a formula is beneficial to the improvement of the wear resistance.
In the wear-resistant glaze material of the technical scheme, anorthite, cordierite and mullite are separated out from the glaze layer by using the combination of the mixture of calcium-containing carbonate, calcined talc, frit and kaolin as main crystal phases to improve the wear resistance of the glaze surface, and the wear resistance of the glaze surface is improved by using corundum and other wear-resistant media in the prior art instead, so that the wear resistance of the glaze surface is high in controllability and good in glaze surface effect, and meanwhile, the separation of crystals in the glaze layer is beneficial to the improvement of the compactness of the glaze layer, and the realization of the antifouling property can be effectively ensured.
Meanwhile, the purpose of the technical scheme is to separate anorthite, cordierite and mullite out of the glaze layer to improve the wear resistance of the glaze, so that the addition of feldspar is avoided in the formula of the wear-resistant glaze material of the technical scheme, and the reduction of the wear resistance of the glaze is avoided.
The purpose of adding feldspar in the glaze at present is mainly three points: firstly, adding potassium and nano feldspar to introduce Na2O and K2O is used for reducing the firing temperature of the glaze; secondly, the active Al in the glaze is increased by introducing a large amount of feldspar raw material2O3In an amount to promote crystallization; thirdly, the active SiO in the glaze is increased by introducing a large amount of feldspar raw material2And (4) content. At present, 15-50% of feldspar is introduced into the glaze to reduce the firing temperature of the glaze and ensureActive Al in glaze2O3Active SiO2If the feldspar is not added, the glaze temperature is too high, so that the glaze is white, the antifouling performance is poor, the color difference is generated and the like.
Although the technical scheme avoids the addition of feldspar in the glaze, the effect of adding feldspar in the existing glaze can be achieved, and the method mainly comprises the following three points: firstly, the frit is added in the formula, so that the firing temperature of the glaze can be reduced; second, the active Al in the glaze is increased by introducing a mixture of frit and kaolin2O3Content, thereby being beneficial to promoting crystallization; third, the active SiO in the glaze is increased by the introduction of calcined talc2And (4) content.
Further, the wear-resistant glaze comprises the following raw material components in percentage by mass: 10-15% of calcium carbonate, 30-35% of calcined talc, 25-30% of frit, 3-5% of calcined zinc oxide and 21-27% of kaolin mixture.
10-15% of calcium-containing carbonate in the formula of the wear-resistant glaze is a provider of calcium elements in an anorthite crystal structure, and when the addition amount of the calcium-containing carbonate is too low, the calcium elements are insufficient for separating anorthite crystals out of a glaze layer; when the addition amount of the calcium carbonate is too high, the performance of the fired glaze of the wear-resistant glaze material is easy to deteriorate, and the glaze is easy to whiten.
30-35% of burning talc in the formula of the wear-resistant glaze is a provider of magnesium element in a cordierite crystal structure, the content of burning talc is lower than 30% and can lead to insufficient content of MgO in the glaze, the wear-resistant performance of the glaze can not be well improved, and when the burning talc is higher than 35%, the glaze performance of the glaze with low-temperature wear-resistant frit after burning is easy to cause deterioration, the glaze is whitish and the transparency is poor.
The 21-27% kaolin mixture is introduced into the formula, so that the suspension property and viscosity of the glaze slip can be guaranteed, when the content of the kaolin mixture is lower than 21%, the glaze slip is too fast in fluidity and easy to precipitate, glazing defects are easily caused, raw materials for precipitating mullite crystals in glaze are easy to be insufficient, and the improvement of wear resistance is not facilitated. When the kaolin mixture is more than 27%, the viscosity of the glaze slip is too high, the fluidity is poor, air bubbles in the glaze slip cannot be discharged, and glazing defects are easily caused.
The content of the frit is required to be kept at 25-30%, and when the content of the frit is less than 25%, CaO and active Al in the wear-resistant glaze are easily caused2O3The content of the frit is not enough, the wear resistance cannot be well improved, and when the frit content is higher than 30%, the glaze is poor in whitening and transparency and poor in color development.
More specifically, the calcium-containing carbonate is any one of dolomite and calcite.
In the prior art, barium carbonate is generally adopted as carbonate in the formula of the wear-resistant glaze, but in the technical scheme, the carbonate component in the glaze is increased by adding dolomite or calcite into the raw materials. This is because if barium carbonate is added into the formula, BaO will be introduced into the glaze, and the introduction of BaO will be impurities compared with anorthite, cordierite and mullite, which will inhibit the crystallization of anorthite, cordierite and mullite, and will also easily result in the decrease of the wear resistance of the glaze.
Meanwhile, as the calcite and the dolomite do not exist only in liquid phase in the firing process, the calcite and the dolomite can provide CaO required by anorthite for crystallization in the glaze firing process, thereby being beneficial to improving the wear resistance of a fired glaze layer. Dolomite or calcite are selected from the wear-resistant glaze, so that carbonate components and calcium oxide components required in the glaze can be provided simultaneously, the wear resistance of the wear-resistant glaze is favorably and fully improved, the good performance of the glaze is ensured, and meanwhile, the production cost can be reduced.
Still further, the kaolin mixture includes kaolin and calcined kaolin.
Further, according to the mass ratio, the kaolin accounts for 8-12% of the raw materials of the wear-resistant glaze, and the calcined kaolin accounts for 13-17% of the raw materials of the wear-resistant glaze.
The kaolin is easy to disperse in water and difficult to precipitate, has better suspension property and viscosity, and the calcined kaolin is sintered in a kaolin calcining furnace to a certain temperature and time so as to have no kaolin suspension property and viscosity any more. The kaolin of 8-12% is introduced into the formula, so that the suspension property and viscosity of the glaze slip can be guaranteed, and when the kaolin is less than 8%, the glaze slip has too high fluidity and is easy to precipitate, so that the glazing defect is easily caused. When the kaolin is higher than 12%, the viscosity of the glaze slip is too high, the fluidity is poor, air bubbles in the glaze slip cannot be discharged, and the glazing defect is easily caused. The rest part is introduced by calcined kaolin, which can effectively ensure the glaze slip performance of the glaze and simultaneously ensure the sufficiency of raw materials for separating out mullite crystals in the glaze.
The kaolin and the calcined kaolin are introduced into the formula to be compounded together, so that the glaze slip performance of the glaze can be ensured. Further, the main component of kaolin and calcined kaolin is SiO2·AL2O3The kaolin is a main raw material for forming mullite crystals in the firing process, so that the introduction of kaolin and calcined kaolin into the formula is beneficial to the improvement of the wear resistance.
Further, the wear-resistant glaze comprises the following raw materials in percentage by mass: 15% of dolomite, 30% of calcined talc, 27% of clinker, 3% of calcined zinc oxide, 10% of kaolin and 15% of calcined kaolin.
The technical scheme also provides the optimal addition proportion of the raw material components of the wear-resistant glaze, and the wear-resistant glaze with the addition proportion is used for preparing the glazed tile, wherein the wear resistance of the glazed tile is 2100 revolutions at the 4 th level, and the wear resistance and the abrasion resistance of the glazed tile at the 6000 revolutions are only 0.05 g.
The preparation method of the wear-resistant glaze comprises the following steps:
(1) mixing the raw materials of the wear-resistant glaze according to the proportion to form a mixture;
(2) and (2) adding the mixture obtained in the step (1) into methylcellulose, sodium tripolyphosphate and water for ball milling to obtain the wear-resistant glaze.
Further, according to the mass ratio, the methyl cellulose, the sodium tripolyphosphate and the water are respectively 0.2%, 0.3% and 41% of the raw materials of the wear-resistant glaze material in sequence.
The methyl cellulose, the sodium tripolyphosphate and the water are respectively 0.2%, 0.3% and 41% of the wear-resistant glaze raw material in sequence, namely, the addition amount of the methyl cellulose is 0.2%, the addition amount of the sodium tripolyphosphate is 0.3% and the addition amount of the water is 41% based on 100% of the addition amount of the wear-resistant glaze raw material.
The addition of methyl cellulose, sodium tripolyphosphate and water into the wear-resistant glaze can fully mix the raw materials in the wear-resistant glaze, and meanwhile, the layering phenomenon between the wear-resistant glaze layer and the bottom glaze layer or the blank layer of the glazed tile is avoided, so that the binding property of the wear-resistant glaze is improved.
Further, the wear-resistant glaze material is sieved by a 325-mesh sieve, and the residue is 0.5-0.7%.
Further, this technical scheme still carries out strict control with the particle size of wear-resisting frit, is favorable to the promotion of wear resistance.
The glazed tile using the wear-resistant glaze material has the wear resistance of 4 grades of 2100 turns and the wear resistance of 6000 turns of 0.05-0.055 g.

Although the kaolin mixtures with different proportions are added into the wear-resistant glaze, the wear resistance of the glazed tile prepared by the kaolin mixtures can be ensured, the glazed tile has the defects in glaze effect observation results, 6000-turn wear resistance and antifouling grade results, wherein the 6000-turn wear resistance and wear resistance is more than or equal to 0.054g, and the antifouling grade is correspondingly reduced.
Therefore, the technical scheme introduces kaolin and calcined kaolin to be compounded together, which is beneficial to ensuring the glaze slip performance of the glaze. Meanwhile, the main component of the kaolin and the calcined kaolin is SiO 2. AL2O3, which is a main raw material for forming mullite crystals in the firing process, so that the introduction of the kaolin and the calcined kaolin into the formula is beneficial to the improvement of the wear resistance.
Comparative example 3-a method for preparing a glazed tile, comprising the steps of:
preparing wear-resistant frit:
a. preparing clinker powder from the wear-resistant clinker raw material, preserving the heat at the melting temperature of 1520 ℃ for 30min, discharging the material and cooling the material by water to prepare clinker; wherein, the frit can be prepared by a conventional frit formula of the glazed tile;
b. the prepared clinker is powdered and sieved.
Preparing glazed tiles:
(1) mixing the raw materials of the protective glaze according to the mass percentage to form a mixture; the protective glaze comprises the following raw materials in percentage by mass: the protective glaze comprises the following raw material components: 5% of albite, 20% of potassium feldspar, 5% of calcite, 13% of dolomite, 78% of wollastonite, 12% of calcined talc, 3% of zinc oxide, 13% of barium carbonate, 8% of kaolin, 5% of calcined soil, 5% of corundum and 4% of quartz;
(2) adding methyl cellulose, sodium tripolyphosphate and water into the mixture obtained in the step (1) for ball milling to obtain a protective glaze, and sieving the protective glaze with a 325-mesh sieve to obtain 0.6% of screen residue; wherein, the methylcellulose, the sodium tripolyphosphate and the water respectively account for 0.2 percent, 0.3 percent and 41 percent of the raw materials of the protective glaze in turn;
(3) applying the ground glaze cloth on a conventional ceramic tile green body; wherein, the ground coat can be prepared by the conventional formulation of the raw materials of the ground coat of the glazed tile;
(4) applying protective glaze cloth on the ceramic tile blank in the step (3);
(5) drying and firing the ceramic tile green body obtained in the step (4) to form a glazed tile; wherein, the ceramic tile green body is sintered by a ceramic roller kiln under the conditions that the temperature is 1180 ℃ and the sintering time is 40 min.
The glazed tile is prepared by adopting the protective glaze, the prepared glazed tile is observed, and the obtained glazed tile is subjected to wear resistance detection test, 6000-turn wear resistance and abrasion resistance determination and antifouling grade determination.
The glazed tile prepared in comparative example 3 had an abrasion resistance of 750 rpm, class 3, and an abrasion resistance of 0.114g at 6000 rpm. Therefore, the wear resistance of the glazed tile prepared by the prior art is lower than that of the glazed tile prepared by the technical scheme, and the 6000-turn wear resistance of the glazed tile prepared by the technical scheme is much lower than that of the glazed tile prepared by the prior art, because the potassium and albite can introduce Na into the glaze material2O and K2O, barium carbonate introduces BaO into the glaze, while the introduction of Na2O, K2O and BaO is impurities relative to anorthite, cordierite and mullite crystals, which inhibits the crystallization of anorthite, cordierite and mullite, and thus leads to the reduction of wear resistance.
The technical principle of the present invention is described above in connection with specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive effort, which would fall within the scope of the present invention.
