Description

Matte anti-slip Yi Jiechao wear-resistant diamond glaze, ceramic tile and preparation method thereof
Technical Field
The invention relates to the technical field of building ceramic materials, in particular to a matte anti-slip Yi Jiechao wear-resistant diamond glaze, a ceramic tile and a preparation method thereof.
Background
With the improvement of the living standard of people, higher requirements are put on the functionality of the ceramic tile. One of the main decorative requirements is to mimic the decorative effect of natural stone. Natural stone is typically a mixture of heterogeneous crystals, for example marble stone is typically a mixture of calcite (calcium carbonate), serpentine (magnesium-containing silicate), dolomite (calcium magnesium carbonate). Therefore, after marble polishing, some gaps are generated at different crystal joints, so that the gloss presents a gradual, fine and three-dimensional feel, which is called "stone light" in the decoration industry. However, it is difficult for a common tile to produce such a gradual gloss, stereoscopic visual effect, and a solution commonly used in the industry is to use engraving ink to form the stereoscopic effect. For example, chinese patent CN115677220a proposes printing with engraving ink and sinking ink on the base coat, so as to form a recessed texture with a greater depth, thereby introducing a stereoscopic impression and a layering impression. Although recessed textures can be formed by adopting the engraving ink, the engraving ink also causes the later glaze to have certain concave-convex degree, the light scattering is enhanced, and the stone-like light visual perception is difficult to form. To solve this problem, a conventional proposal is to greatly improve the light transmittance of the overglaze, for example, a dry granular glaze with high transparency is adopted in the above patent. However, the dry granular glaze mainly comprises a glass body, which necessarily means that harder crystals (such as mullite and the like) in the overglaze layer are reduced, the glaze hardness is reduced, and the wear resistance is greatly reduced.
On the other hand, with respect to the function of the wear resistance of the ceramic tile, the prior art CN114772933B discloses a nano soft super wear-resistant diamond glaze, ceramic tile and a preparation method thereof, wherein zirconia grains, zirconium silicate grains and zirconium-containing silicate M grains are introduced into the diamond glaze, so that the diamond glaze has the advantages of high hardness, high wear resistance and high transparency. However, when the glaze is used for a brick surface with micro concave-convex, the scattering effect is strong, the transmission effect is weakened, and the visual perception similar to stone light is difficult to be generated by a user.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the following detailed description.
In the conventional stone-like bricks, in order to enhance the decorative effect of stone-like light, a high-light-transmittance overglaze is often used. However, high light transmittance often means that the glass body is increased, the content of crystalline phase is reduced, the hardness of the glaze is greatly reduced, and the wear resistance is greatly reduced. The technical scheme is further deepened on the basis of the applicant's preamble research, and creatively provides the glaze which can keep high light transmittance on the concave-convex structure, high wear resistance and skid resistance and easy cleaning. The specific steps are as follows:
the invention provides a matte anti-slip Yi Jiechao wear-resistant diamond glaze which comprises the following chemical components in percentage by weight: siO (SiO) 2 57%-70%,Al 2 O 3 4%-10%,K 2 O+Na 2 O=1%-4%,CaO+MgO+ZnO+BaO=15%-35%,ZrO 2 1.5%-4.5%,Fe 2 O 3 +TiO 2 =0.05% -0.55%, (cao+mgo)/(zno+bao) =1.5-2.5; loss On Ignition (LOI) is 0.5% -3%.
Based on the chemical components, cristobalite crystal grains, nano zirconia crystal grains, zirconium silicate crystal grains, zirconium-containing barium silicate crystal grains and zirconium-containing zinc silicate crystal grains are commonly formed in the glaze layer obtained after firing, and Al mainly exists in a glass body, so that the light transmission performance of the glaze layer is greatly optimized, the light can still be well transmitted under the condition that a micro concave-convex structure exists, and further the gradual three-dimensional decorative effect similar to stone light is formed. Meanwhile, due to the existence of the crystals, the glaze layer has the advantages of high hardness, high wear resistance, skid resistance and easy cleaning.
In particular, the invention controls SiO 2 The content is 57-70 wt%, siO 2 After firing, the glass is mainly in the form of glass body and cristobalite. The invention is realized by introducing a large amount of SiO 2 The content of square quartz crystals in the glaze after firing can be improved, and the light transmittance, especially the light transmittance under the condition of the micro concave-convex structure, is improved.In particular, when SiO 2 When the weight percentage is less than 57%, the precipitation amount of the cristobalite is less, and the light transmittance is poor when the micro concave-convex structure exists, so that the decorative effect of stone light is difficult to endow the glaze; when SiO 2 When the weight percentage is more than 70%, the viscosity of the glass body formed in the firing process is too high, other crystals (such as zirconia, zirconium silicate and the like) are affected to be separated out, and the wear resistance, the skid resistance and the antifouling performance of the glaze are weakened. In addition, excessive SiO 2 The glossiness of the glaze surface is improved, and the effect of matte (glossiness is less than 15) is difficult to achieve.
Wherein, unlike conventional glazes, al in the present invention 2 O 3 Mainly ablated in the vitreous body without forming individual acicular mullite crystals. Acicular mullite crystals reduce the light transmission properties of the glaze in the presence of micro-relief structures. For this purpose, control Al 2 O 3 The content of (C) is 4-10 wt%.
Wherein the invention controls K 2 O+Na 2 O=1 wt% -4wt%, K, na is embedded more into SiO 2 -Al 2 O 3 Among the formed glass bodies, the viscosity of the glass body at high temperature is adjusted, so that good conditions are created for ordered precipitation of each crystal grain, and the wear resistance, the skid resistance and the antifouling performance of the glaze are ensured. Specifically, when K 2 O+Na 2 When O is more than 4wt%, the high temperature viscosity of the glass body is too low, but the cristobalite crystal grains, the nanometer zirconia crystal grains, the zirconium silicate crystal grains, the zirconium-containing barium silicate crystal grains and the zirconium-containing zinc silicate crystal grains can be melted, so that the wear resistance, the skid resistance, the antifouling performance and the light transmittance of the glaze are reduced. When K is 2 O+Na 2 When O is less than 1wt%, the high-temperature viscosity of the glass body is too high, which is not beneficial to grain precipitation; meanwhile, the micro concave-convex structure is further expanded, while the glossiness of the glaze is reduced, and the anti-skid performance is improved; however, the stone light decorative effect disappears, and the antifouling performance is reduced.
The CaO and MgO are main flux components, the moving radius of the flux components in the glass phase is large, the fluxing effect is strong, but the dispersion degree of the glass body containing the CaO and MgO is high, and the flux components are not beneficial to the building of the stone light decorative effect of three-dimensional layering sense. Ba. The Zn has large ionic radius and narrower moving range in the glass body, can increase the gloss of the glaze, improve the refractive index, reduce the dispersion and diffuse reflection, and is beneficial to forming the decorative effect of 'stone light'. Therefore, the invention controls CaO+MgO+ZnO+BaO=15 wt% to 35wt%, and controls (CaO+MgO)/(ZnO+BaO) =1.5 to 2.5; if (CaO+MgO)/(ZnO+BaO) < 1.5, the glossiness of the finished glaze is improved, the matte effect is difficult to achieve, and the stone polishing effect is also lost. If (CaO+MgO)/(ZnO+BaO) > 2.5, the precipitated crystals in the glaze are reduced, so that not only are the wear resistance, the skid resistance and the antifouling property of the glaze reduced, but also the decorative effect of 'stone light' is avoided.
Wherein ZrO 2 Is the main source component of various grains, and the content of the grain is controlled to be 1.5 to 4.5 weight percent.
Wherein Fe is 2 O 3 +TiO 2 Is a main impurity substance whose content is less than 0.8wt% to prevent it from affecting light transmission properties, especially in the presence of micro-relief structures. Preferably, fe is controlled 2 O 3 +TiO 2 0.05wt%-0.55wt%。
Based on the formula, the types of crystals and the sizes of the crystals in the glaze obtained after firing can be well controlled, a reasonable crystal grain and glass body system is constructed, and the wear resistance, the skid resistance, the antifouling performance and the light transmittance of the glaze are improved. Specifically, the grain size of the square quartz crystal grain is 50-1000 nanometers, the grain size of the nanometer zirconia crystal grain is 100-1000 nanometers, the grain size of the zirconium silicate crystal grain is 1-10 micrometers, the grain size of the zirconium-containing barium silicate crystal grain is 1-12 micrometers, and the grain size of the zirconium-containing zinc silicate crystal grain is 1-12 micrometers. By controlling the size of the crystal grains, the crystal grains are uniformly distributed to form a reasonable network frame, so that the reinforcing and toughening effects are effectively exerted, and the wear resistance, the anti-skid performance, the antifouling performance and the matte effect are ensured while the high light transmittance performance is ensured.
Preferably, in one embodiment of the present invention, the matte anti-slip Yi Jiechao wear resistant diamond glaze comprises the following chemical components in weight percent:
SiO 2 60%-68%,Al 2 O 3 4%-8%,K 2 O+Na 2 O=2%-4%,CaO+MgO+ZnO+BaO=20%-30%,ZrO 2 3%-4.5%,(CaO+MgO)/(ZnO+BaO)=1.8-2.5,Fe 2 O 3 +TiO 2 =0.05% -0.2%; the loss on ignition is 1% -3%.
More preferably, in one embodiment of the present invention, the matte anti-slip Yi Jiechao wear resistant diamond glaze comprises the following chemical components in weight percent:
SiO 2 62%-68%,Al 2 O 3 4%-7%,K 2 O+Na 2 O=2%-4%,CaO+MgO+ZnO+BaO=20%-28%,ZrO 2 3%-4.5%,(CaO+MgO)/(ZnO+BaO)=1.8-2.5,Fe 2 O 3 +TiO 2 =0.05% -0.2%; the loss on ignition is 1% -3%.
Wherein, in some embodiments of the invention, al is further controlled 2 O 3 /(K 2 O+Na 2 O) =2-4 (weight ratio). Based on the above control, the performance of the high temperature glass body can be optimized, the precipitation of cristobalite grains, nano zirconia grains, zirconium silicate grains, zirconium-containing barium silicate grains and zirconium-containing zinc silicate grains can be further promoted, and the grain size of each grain can be optimized. So that the stone light effect of the glaze is better, and the wear resistance, the skid resistance and the antifouling performance are stronger. Based on the control, a quick cooling process can be adopted in the cooling process, so that the firing period is greatly shortened, and the ceramic tile yield is improved.

Based on the control, the cristobalite crystal grains with smaller grain size and the nano zirconia crystal grains are dispersed and distributed in a frame structure formed by the micron-sized zirconium silicate crystal grains, the zirconium-containing barium silicate crystal grains and the zirconium-containing zinc silicate crystal grains, so that the effect of dispersion strengthening is achieved, the wear resistance and the skid resistance are further improved, and meanwhile, the stone light decorative effect is further enhanced due to the dispersion distribution of the cristobalite crystal grains.

SiO 2 50%-60%,Al 2 O 3 11%-18%,K 2 O+Na 2 o=1-3%, cao+mgo+zno+sro+bao=15-30%, loss on ignition 1-5%; wherein SiO is 2 /Al 2 O 3 =3.0-3.5。
It should be noted that, the conventional protective glaze is generally applied by screen printing, and the applied area coincides with the applied area of the subsequent engraving ink.

According to the invention, the protective glaze layer is integrally applied on the ink-jet printing layer to form the protective glaze layer, and the protective glaze layer not only has a good color development effect, but also ensures that the patterns have stable color development and strong transparent feeling. And the ink can be well matched with the engraving ink of the subsequent engraving layer, the depth of the micro-concave-convex structure is increased, the stereoscopic impression is increased, and the deviation of the decorative effect caused by the non-ideal alignment of the pattern is weakened. In addition, the protective glaze layer can be well matched with the subsequent matte anti-skid Yi Jiechao wear-resistant diamond glaze layer, so that gradual change layering sense is optimized, and the decorative effect of stone light is optimized.

When SiO 2 /Al 2 O 3 When the color is more than 3.5, the subsequent engraving ink permeation is not facilitated, and the three-dimensional sense of the pattern is weakened.
