Description
Technical Field
The invention relates to the technical field of architectural ceramics, in particular to a surface scale texture antiskid porcelain tile and a preparation method thereof.
Background
With the increasing aging degree of the population in China, how to protect the walking safety of the old people becomes a focus point. The ceramic industry is currently focusing on the study of non-slip tiles. The technological method mainly comprises the following two methods, namely, the friction coefficient is increased by means of the effect of a mould with an uneven surface, and anti-skid particles are applied to the surface of the glaze of a green brick, such as various dry particles commonly adopted in the industry at present. Both of these techniques have limitations. In the first technical method, the uneven effect is formed by a mould, the surface is rough and not delicate enough, and certain walking safety risk still exists. Although the second technical method relies on the anti-skid particles to form a better anti-skid effect, the particles are easy to collide and fall off in the later use process, and the particles are easy to store dirt and are difficult to clean.
Disclosure of Invention
In order to solve the problems, the invention aims to provide a surface scale texture antiskid porcelain tile and a preparation method thereof. The raised scale has clear texture, exquisite form, good surface skid resistance and stain resistance, and is easy to clean. The dry method and wet method static friction coefficients of the scale glaze layer generated by the glaze material are close to each other by detection, so that the antiskid effect of the scale glaze layer cannot be greatly reduced due to the change of the use environment.
In a first aspect, the invention provides a preparation method of a surface scale texture antiskid ceramic tile, which comprises the following steps:
applying base glaze on the surface of the green brick;
applying texture glaze on the surface of the green brick after the ground glaze is applied; the thermal expansion coefficient of the ground glaze is 5.7 multiplied by 10 higher than that of the texture glaze-6～7.5×10-6The melting temperature of the texture glaze is 25-35 ℃ higher than that of the ground glaze;
and drying and firing the green brick subjected to the texture glazing to obtain the surface scale texture anti-slip ceramic brick.
Preferably, the thermal expansion coefficient of the texture glaze is 2.1 x 10-6～3.5×10-6The thermal expansion coefficient of the ground coat is 9.2 multiplied by 10 DEG C-6～9.6×10-6/℃。
Preferably, the textured glaze has a surface tension in the melting temperature range of 0.39 x 10-3～0.43×10-3N/m。
Preferably, the melting temperature of the texture glaze is 1150-1185 ℃, and the melting temperature of the ground glaze is 1125-1155 ℃.
Preferably, the chemical composition of the ground glaze comprises: by mass percent, SiO2：52.3～58.2％、Al2O3: 26.3-32.2%, CaO: 4.3-5.6%, alkali metal oxide: 3.9E6.5％、ZrO2：4.2～6.8％。
Preferably, the texture glaze has a chemical composition comprising: by mass percent, SiO2：55.6～63.2％、Al2O3: 7.9 to 12.3%, alkaline earth metal oxide: 16.9 to 24.1%, alkali metal oxide: 2.2-5.1%, ZnO: 3.3 to 5.8 percent.
The mechanism of the scale texture formation of the present invention includes two aspects: the thermal expansion coefficients of the ground glaze and the texture glaze are different, and the thermal expansion coefficient of the ground glaze is larger than that of the texture glaze, so that the ground glaze can form compressive stress on the contact part of the texture glaze and the ground glaze in the cooling process of a cooling zone of a kiln, and further the extrusion effect is generated; the second is a texture glaze which mainly comprises non-surface active oxide Al2O3、CaO、Li2O, MgO, etc., do not contain strong surface active oxides (e.g., V)2O5、Cr2O3) And weakly surface active oxides (e.g. P)2O5、B2O3、Bi2O3、PbO、Sb2O3) The principle that the surface tension of a texture glaze melt consisting of non-surface active oxides increases along with the reduction of the temperature in the process from a high-temperature sintering state to gradual temperature reduction. In the invention, the melt shrinkage is formed by utilizing the compressive stress of the ground glaze on the texture glaze and matching with the texture glaze with large surface tension, so that the texture glaze melt on the lower half part gradually floats to the surface, and further, the scale raised texture is gradually formed in the cooling process.
The scale texture glaze of the existing ceramic tile adopts partial strong surface active oxide V2O5And part of the weakly surface-active oxide P2O5、Sb2O3And especially, a multi-layer application process (usually more than three layers) is used, for example, a cotton gauze is matched in the second glaze layer, and a grid-shaped gully effect is formed by depending on the texture of the gauze and matching with the action of glaze components, which is essentially different from the texture of the upward-convex scales formed by utilizing the large surface tension of the texture glaze and the difference of the expansion coefficients of the texture glaze and the ground glaze in the invention.
Preferably, K in the texture glaze2O and Na2The total amount of O is controlled to be less than 2.5%, which is advantageous for the texture glaze to have a surface tension of 0.39X 10 in the melting temperature range-3～0.43×10-3N/m range.
Preferably, the application mode of the ground coat is glaze spraying, and the specific gravity is 1.40-1.45 g/cm3The application amount is 450 to 550g/m2。
Preferably, the texture glaze is applied by spraying glaze, and the specific gravity of the texture glaze is 1.83-1.87 g/cm3The application amount is 800 to 950g/m2。
Preferably, the maximum firing temperature is 1175-1195 ℃, and the firing period is 50-60 minutes.
According to the preparation method of the surface scale texture antiskid porcelain tile, the difference range of the thermal expansion coefficients of the ground glaze and the texture glaze, the glazing amount of the texture glaze and the chemical composition of the texture glaze are mainly controlled to control the surface tension of the glaze melt, so that the surface tension of the texture glaze in the melting temperature range is in a proper range, and the formed raised texture is ensured not to be leveled again or excessively and obviously formed into the peak-shaped raised texture.
In a second aspect, the invention also provides the surface scaly texture antiskid ceramic tile obtained by the preparation method.

Detailed Description
The present invention is further illustrated by the following examples, which are to be understood as merely illustrative of, and not restrictive on, the present invention. The following percentages are by mass unless otherwise specified. The loss on ignition refers to CO decomposed from crystal water and carbonate discharged in the process of burning the detected material2SO of sulfate decomposition2And the loss of the quality of the rest materials of other organic impurities caused by burning and gasifying.
The following is an exemplary description of the method for preparing the surface scale texture anti-slip porcelain tile of the present invention.
And (5) preparing a green brick. The green body powder may be press-formed to obtain a green brick. The chemical composition of the green body powder is not limited, and any green body powder commonly used in the art can be applied to the present invention.
And drying the green brick. The drying temperature can be 150-200 ℃, and the drying time can be 60-70 min.
And applying base glaze on the surface of the dried green brick. The ground glaze has the following functions: the first step is used for covering the base color and flaws of the blank; secondly, a larger compressive stress is generated on the upper layer texture glaze, and the formation of the scale texture of the texture glaze is promoted.
As an example, the chemical composition of the ground glaze comprises: in terms of mass percent, SiO2：52.3～58.2％、Al2O3：26.3～32.2％、CaO：4.3～5.6％、K2O：2.7～3.7％、Na2O：1.2～2.8％、ZrO2: 4.2-6.8%, loss on ignition: 1.5 to 3.2 percent.
The melting temperature of the ground glaze is 1125-1155 ℃, so that decomposable components in the ground glaze can be decomposed as soon as possible, and glaze defects such as miliaria and the like on the texture glaze can be avoided.
The thermal expansion coefficient (at 40-600 ℃) of the ground glaze is 9.2 multiplied by 10-6～9.6×10-6And the temperature is controlled to be higher than the temperature of the ground coat, so that the ground coat has a larger shrinkage effect in the cooling process.
The ground coat may be applied by spraying, which reduces the occurrence of pinholes. In some embodiments, the ground coat may have a specific gravity of 1.40 to 1.45g/cm3The application amount can be 450-550 g/m2The range of the glazing amount can better cover the blank bottom.
In some embodiments, the base coat comprises the following raw materials: in parts by weight: 25-40 parts of potash feldspar, 5-8 parts of nepheline, 10-15 parts of wollastonite, 6-11 parts of water-washed kaolin, 15-20 parts of calcined kaolin, 10-15 parts of quartz, 6-10 parts of zirconium silicate and 12-15 parts of calcined alumina.
The ground glaze can be prepared by the following steps: respectively burdening according to the weight part ratio of each component; according to the reference: ball: the mass ratio of water is 1:1.5:0.35, ball milling is carried out for 5-6 hours by a wet method, the fineness of the glaze slip reaches 0.3-0.5 wt% of 325 meshes, and then iron is removed and sieved for later use.
And drying the green brick after the ground glaze is applied. The drying temperature can be 90-130 ℃, and the drying time can be 3-5 min.
And applying texture glaze on the surface of the dried green brick.
As an example, the chemical composition of the texture glaze includes: by mass percent, SiO2：55.6～63.2％、Al2O3：7.9～12.3％、CaO：6.3～9.3％、MgO：2.1～3.6％、K2O：0.7～1.1％、BaO：8.5～11.2％、Na2O：0.2～0.7％、Li2O: 1.3-3.3%, ZnO: 3.3-5.8%, loss on ignition: 3.5 to 4.9 percent.
In the chemical composition of the textured glaze, K2O and Na2The total amount of O should be controlled to be less than 2.5%, mainly because of K2O and Na2O has a small surface tension at high temperatures, which is disadvantageous in connection with the generation of scale texture. Further, Al2O3The percentage of (C) should be controlled to be more than 7% because of Al2O3The high-temperature surface tension is very large, which is beneficial to the generation of scale texture.
The melting temperature of the texture glaze is controlled to be lower than 1200 ℃, preferably 1150-1185 ℃, because too high melting temperature can cause the texture glaze to be excessively vitrified, and the later glaze surface anti-slip performance is reduced.
The thermal expansion coefficient of the texture glaze should be controlled to be lower than 5.5 x 10-6In the range of/° C, for example, the coefficient of thermal expansion (at 40 to 600 ℃) is 2.1X 10-6～3.5×10-6The texture glaze is such that it will shrink less during cooling.
Preferably, the thermal expansion coefficient of the ground glaze is 5.7 × 10 higher than that of the texture glaze-6～7.5×10-6/℃. If the difference between the thermal expansion coefficients of the texture glaze and the ground glaze is less than 5.7 x 10-6/° c (especially less than 5.0 x 10)-6/° c), a sufficiently obvious scale texture effect is not easily formed; if the difference between the thermal expansion coefficients of the overglaze and the ground glaze is higher than 7.5 multiplied by 10-6/° c (especially above 9.5 × 10)-6/° c), the formed scale texture is too large or too convex to cause collision and falling, or the generated texture is a non-scale effect texture but an irregular deformation texture.
Preferably, the melting temperature of the texture glaze is 25-35 ℃ higher than that of the ground glaze. If the difference value of the starting melting temperatures of the texture glaze and the ground glaze is lower than 10 ℃, the ground glaze and the texture glaze are easy to melt simultaneously, and the burning loss components of the ground glaze generate adverse defects on the texture glaze, such as miliaria and the like; if the difference between the melting temperatures of the texture glaze and the ground glaze is higher than 35 ℃ (especially higher than 50 ℃), the ground glaze is easy to be burnt, the texture glaze is not completely melted, the ground glaze flows, and the components of the texture glaze are too much melted into the ground glaze, so that the scale texture cannot be formed uniformly.
It is worth to say that in the existing scale texture glaze, part of the strong surface active oxide V is mainly used2O5And part of the weakly surface-active oxide P2O5、Sb2O3The components cause the surface tension of the glaze to be too small, flow is generated, and a grid-shaped gully effect is formed by matching with a cotton gauze and depending on the texture of the gauze, and the glaze concave effect is generated essentially; the invention forms the scale texture which is convex upwards by utilizing the large surface tension of the texture glaze and the difference of the thermal expansion coefficients of the texture glaze and the ground glaze, which is one of the essential differences between the texture glaze and the ground glaze in the prior art.
The texture glaze can be applied in a glaze pouring mode, and the glaze layer can be ensured to be uniform in thickness by adopting the glaze pouring mode, so that the scale texture formed in the later stage is uniform.
In order to form scale-like texture, the glazing amount of the texture glaze is required to be not less than 700g/m2. If the glazing amount is too small, the texture of the formed scale is not obvious enough, and even the scale cannot be formedAnd (4) texture.
The mechanism of the scale texture formation of the present invention includes two aspects: the thermal expansion coefficients of the ground glaze and the texture glaze are different, the thermal expansion coefficient of the ground glaze is larger than that of the texture glaze, and the ground glaze can form compressive stress on the contact part of the texture glaze and the ground glaze in the cooling process of a cooling zone of a kiln to generate an extrusion effect; the second is a texture glaze which mainly comprises non-surface active oxide Al2O3、CaO、Li2O, MgO, etc., do not contain strong surface active oxides (e.g., V)2O5、Cr2O3) And weakly surface active oxides (e.g. P)2O5、B2O3、Bi2O3、PbO、Sb2O3) The principle that the surface tension of the texture glaze melt consisting of the non-surface active oxide is increased along with the reduction of the temperature in the process of gradually reducing the temperature from the high-temperature state of sintering is adopted, so that the raised texture can not be melted down. In summary, the compressive stress of the ground glaze on the texture glaze is matched with the shrinkage of the texture glaze melt with high surface tension, so that the texture glaze melt below gradually floats to the surface, and further, the scale raised texture is gradually formed in the cooling process. In the test process of the invention, the difference range of the thermal expansion coefficients of the ground glaze and the texture glaze, the glazing amount of the texture glaze and the chemical composition of the texture glaze are required to be controlled to control the surface tension of the glaze melt, and the surface tension of the texture glaze in the melting temperature range must be 0.39 multiplied by 10-3～0.43×10-3The N/m range ensures that the formed raised texture cannot be leveled again or form a peak-like raised texture too remarkably. In the previous experiment, since the chemical composition of the texture glaze is not properly adjusted, the surface tension of the texture glaze is measured to be lower than 0.30 × 10 according to the surface tension value of each component at 1100 ℃ in the book "ceramic technology" (using a relational formula of glaze surface tension and chemical composition, σ glaze ═ W1 ═ W2 ∑ σ 2+ W3 ∑ σ 3+. where σ glaze is the surface tension of the glaze, W1, W2, W3... are the contents of different components, and σ 1, σ 2, σ 3.. are the surface tensions of different components), and the surface tension of the texture glaze is measured to be lower than 0.30 × 10 ℃.-3N/m, so that the glaze surface is flat and cannot form raised scale textures.
In some embodiments, the texture glaze has a raw material composition, in parts by weight, comprising: 10-25 parts of matte clinker powder, 2-5 parts of zinc oxide, 5-10 parts of calcined talc, 15-20 parts of wollastonite, 10-15 parts of barium carbonate, 0-5 parts of calcined alumina, 8-12 parts of water-washed kaolin, 3-6 parts of calcined kaolin and 30-45 parts of quartz.
By way of example, the matte fusible mass powder consists of the following raw materials in parts by weight: 5-10 parts of potassium feldspar, 5-10 parts of nepheline powder, 10-15 parts of lithium carbonate, 15-25 parts of quartz, 15-20 parts of talcum powder, 18-23 parts of barium carbonate and 8-15 parts of corundum powder.
The preparation method of the matte fusion block powder comprises the following steps: mixing the raw materials in parts by weight, grinding the raw materials into powder, preserving heat at the melting temperature (1510 ℃ -1515 ℃) for 30-40 minutes, discharging, cooling by water, crushing the powder into clinker powder, drying and sieving the clinker powder, and taking the clinker powder which is sieved by a 120-mesh sieve for later use.
The dry static friction coefficient and the wet static friction coefficient of the surface scale texture antiskid porcelain brick obtained by the invention are both above 0.82, and the difference between the dry friction coefficient and the wet friction coefficient is within 0.03.
