BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Figure 1 is a flowchart of a preferred embodiment of the preparation method of a wear-resistant ceramic tile in the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] In order to make the purpose, technical solution and advantages of the present invention clearer and more definite, the following further describes the present invention in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] With the development of traditional industrial and mining industries and related regions, the stockpiles of bulk solid waste generated by them are gradually increasing, such as the large amount of metallurgical slag generated. If these metallurgical slags cannot be effectively and efficiently utilized, it will bring great resistance to the green upgrading and development of traditional industrial and mining industries. Therefore, it has particularly important practical significance to reasonably utilize bulk solid waste such as metallurgical slag to prepare wear-resistant ceramic tiles suitable for outdoor public places.

[0035] Please refer to Figure 1 , Figure 1 which is a flowchart of the preparation method of the wear-resistant ceramic tile in the present invention. As Figure 1 shown, the preparation method of the wear-resistant ceramic tile described in the embodiment of the present invention includes the following steps:

[0036] Step S100: Press the prepared ceramic tile powder and metal material into a composite ceramic green body, wherein the raw material formula of the ceramic tile powder includes metallurgical slag;

[0037] Step S200: Process the composite ceramic green body to obtain the wear-resistant ceramic tile; wherein, the raw materials of the metallurgical slag, by weight, include 55-70 parts of vanadium-titanium slag and 10-20 parts of red mud.

[0038] Specifically, the embodiment of the present application is a method for preparing wear-resistant ceramic tiles applicable to outdoor public places using metallurgical slag, which solves the problem that the application of metallurgical slag in building ceramic production does not match the traditional building ceramic body formula system. Through the high-temperature sintering process of building ceramic production, the harmful components in the metallurgical slag can be solidified, reducing the harm to the environment caused by the stacking of metallurgical slag and improving the utilization rate of solid waste resources. Moreover, the wettability problem between the metal and non-metal phases during the process of enhancing and toughening building ceramics with metal phases is solved. Since the building ceramic formula adjusted using metallurgical slag contains a large amount of metal phases and metal oxides, the matching problem of the traditional ceramic formula system and the wettability of metal materials can be solved, thereby preparing ceramic products with better performance and higher quality.

[0039] In addition, by using the multi-component phase composition in the metallurgical slag, the firing time of the composite ceramic tile can be shortened, the firing temperature can be reduced, and the problems of long firing time and high firing temperature of traditional ceramics are solved. In one embodiment of the present application, the mass percentage of Fe 2 O 3 in the metallurgical slag is greater than 35%, and the sum of the mass percentages of other metal oxides is greater than 5%.

[0040] In the embodiment of the present application, the chemical components of the vanadium-titanium slag, calculated by mass percentage, include: loss on ignition 1% - 1.5%, Al 2 O 3 3.5% - 5%, SiO 2 12% - 20%, Fe 2 O 3 40% - 50%, CaO 2% - 4%, MgO 2.5% - 4%, K 2 O 0.01% - 0.05%, Na 2 O 3.5% - 6%, TiO 2 9% - 15%, MnO 7% - 12%, Cr 2 O 3 2% - 6%, V 2 O 5 0.5% - 2%.

[0041] Specifically, vanadium-titanium slag is a smelting waste residue containing vanadium and titanium, mainly from the steelmaking and ironmaking processes. The embodiment of the present application uses a large amount of metallurgical slag to prepare ceramic tiles, which can greatly reduce the environmental pollution problems caused by the stacking of metallurgical slag and realize the utilization of solid waste.

[0042] In one embodiment of the present application, the chemical components of the red mud, calculated by mass percentage, include: loss on ignition 8% - 12%, Al 2 O 3 18.5% - 23%, SiO2 12.5% - 18.5%, Fe 2 O 3 30.5% - 40%, CaO 4.5% - 6.5%, MgO 0.1% - 0.5%, K 2 O 0.1% - 1%, Na 2 O 5% - 8%, TiO 2 3% - 6%.

[0043] Specifically, red mud is an industrial solid waste discharged during the extraction of alumina in the aluminum industry, with a large amount of iron oxide.

[0044] The metallurgical slag used in the embodiments of this application is mainly metallurgical slag with a relatively high iron content such as vanadium-titanium slag and red mud, which contains a large amount of metal oxides, especially a relatively high iron oxide content. The metal material is iron, steel or alloy steel mainly composed of iron elements. There is good compatibility between the metallurgical slag and the metal material. Therefore, when the metallurgical slag and the iron-based metal material are co-fired, the wettability problem between them can be effectively improved.

[0045] In the embodiments of this application, the phases of the vanadium-titanium slag include: hematite, manganese ferrite spinel, ilmenite, magnesioferrite titanate, clinorutile, and rutile.

[0046] Specifically, the phase composition of the vanadium-titanium slag is: hematite (Fe 2 O 3 ), hematite (chromium-containing) (Fe 0.6 Cr 0.4 ), 2 O 3 manganese ferrite spinel MnFe 2 O 4 , ilmenite Fe +2 TiO 3 , magnesioferrite titanate (Mg, Fe)(Ti 3 Fe)O 10 , clinorutile V 2 +3 Ti 3 O 9 and a small amount of rutile TiO 2 .

[0047] The vanadium-titanium slag in the embodiments of this application contains a large number of different types of crystal phases, and the content of the glass phase is greatly reduced. As a result, the metallurgical slag also contains a large number of different types of crystal phases and the content of the glass phase is also greatly reduced. In this way, during the high-temperature firing process, various crystal phases are intertwined and connected, thereby improving the strength and toughness of the ceramic product. It solves the problems that when traditional ceramics are applied to places with a large number of people such as subway stations, squares, and shopping malls, the cost of marble is relatively high, the surface of ceramic tiles is easy to wear and discolor, and the strength is relatively low and easy to break.

[0048] In the embodiment of the present application, the raw material formula of the ceramic tile powder includes, by weight: 13-20 parts of ball clay, 1-5 parts of bentonite, 1-7 parts of black talc, 70-80 parts of metallurgical slag, and 0.3-0.5 part of body deflocculant.

[0049] Specifically, the ceramic tile powder is obtained by aging and homogenizing the raw materials in the raw material formula, and then grinding them in a ball mill according to the formula ratio through a feeder to obtain a slurry meeting the fineness requirements. After screening, aging, and impurity removal, the slurry is spray-dried to obtain the ceramic tile powder.

[0050] The body deflocculant includes one or more of a composite diluent, sodium tripolyphosphate, sodium metaphosphate, sodium humate, and sodium silicate.

[0051] In the embodiment of the present application, the chemical components of the ceramic tile powder, by weight, include:

[0052] SiO 2 25-35 parts, Al 2 O 3 5-15 parts, K 2 O 0.5-2 parts, Na 2 O 1-6 parts, CaO 1-3 parts, MgO 1.5-3.5 parts, TiO 2 7.5-11 parts, Fe 2 O 3 25-40 parts, Cr 2 O 3 2.5-3.5 parts, MnO 4.5-7 parts.

[0053] In the embodiment of the present application, the metal material is a metal wire; the prepared ceramic tile powder and the metal material are pressed into a composite ceramic blank, including:

[0054] Using the prepared ceramic tile powder to lay a first powder layer, and laying the metal wire on the first powder layer to obtain a metal wire layer;

[0055] Using the prepared ceramic tile powder to lay a second powder layer on the metal wire layer;

[0056] Pressing the first powder layer, the metal wire layer, and the second powder layer into a composite ceramic blank.

[0057] Specifically, when the metal material in the embodiments of the present application is a metal wire, a multi-layer fabric method is adopted. First, a layer of ceramic tile powder is laid, then the metal wire is laid, and finally another layer of ceramic tile powder is laid, and then it is pressed into a composite ceramic green body by a press. The metal wire is an iron wire, a carbon steel wire or an alloy steel wire, and the alloy steel wire is mainly an alloy steel wire containing metal elements such as manganese, titanium, chromium, silicon, and aluminum. The diameter of the metal wire is 0.1 - 1 mm. When using the metal wire, the distribution method of the metal wire adopts a criss-cross laying method, and the laying density is 4 - 25 holes per square centimeter. The laying length and width need to reserve the shrinkage length of the green body during firing. For example, when the shrinkage of the green body during firing is 8‰, the laying range of the metal wire needs to be 8‰ shorter than the four sides of the pressing die to ensure that the metal wire will not be exposed due to the shrinkage of the green body during firing.

[0058] The metallurgical slag used in the embodiments of the present application is mainly metallurgical slag with a relatively high iron content such as vanadium-titanium slag and red mud, which contains a large amount of metal oxides, especially a relatively high iron oxide content. The metal wire is an iron wire, a steel wire, or an alloy steel wire mainly composed of iron elements, and the two have good compatibility. Therefore, when the metallurgical slag and the iron-based metal wire are co-fired, the wettability problem between the metallurgical slag and the metal wire can be effectively improved. The preparation difficulty of the cermet lies in the wettability problem between the metal phase and the non-metal phase. Therefore, by utilizing the characteristics of these components in the metallurgical slag, a metal-non-metal composite ceramic with better effects can be prepared. The ceramic added with the metal material can greatly improve its toughness and increase its elastic limit. At the same time, since the metallurgical slag contains a large number of different types of crystal phases and the content of the glass phase is greatly reduced, various crystal phases in the ceramic formulation system are interlaced and connected with each other during the high-temperature firing process, thereby improving the strength and toughness of the ceramic product. And by adopting the whole-body preparation process to prepare the ceramic product, it can be permanently applied to outdoor places without discoloration, improving its durability.

[0059] In another embodiment of the present application, the metal material is a metal fiber; pressing the prepared ceramic tile powder and the metal material into a composite ceramic green body, including:

[0060] Mixing and pressing the prepared ceramic tile powder and the metal fiber to obtain a composite ceramic green body. The metal fiber accounts for 0.5% - 5% of the ceramic tile powder by weight percentage;

[0061] Among them, the aspect ratio of the metal fiber is 1 - 10, and the length of the metal fiber is 0.1 - 2 mm.

[0062] Specifically, the metal fiber is an iron fiber, a carbon steel fiber, or an alloy steel fiber, and the alloy steel fiber is mainly an alloy steel fiber containing metal elements such as manganese, titanium, chromium, and aluminum.

[0063] The diameter of the metal fiber is 0.1 - 1 mm. When using metal fibers, the metal fibers need to be mixed and pressed together with the ceramic tile powder. The aspect ratio of the metal fiber is 1 - 10, and the length of the metal fiber is 0.1 - 2 mm.

[0064] The metallurgical slag used in the embodiments of the present application is mainly metallurgical slag with a relatively high iron content such as vanadium-titanium slag and red mud, which contains a large amount of metal oxides, especially a relatively high iron oxide content. The metal fiber is an iron fiber, steel fiber, or alloy steel fiber mainly composed of iron element. The two have good compatibility. Therefore, when the metallurgical slag and the iron-based metal fiber are co-fired, the wettability problem between the metallurgical slag and the metal fiber can be effectively improved. The preparation difficulty of metal ceramics lies in the wetting problem between the metal phase and the non-metal phase. Therefore, by utilizing the characteristics of these components in the metallurgical slag, a better metal-non-metal composite ceramic can be prepared. The ceramic added with metal materials can greatly improve its toughness and increase its elastic limit. At the same time, due to the large amount of different types of crystal phases in the metallurgical slag and the significant reduction in the glass phase content, various crystal phases in the ceramic formulation system are interlaced and connected with each other during the high-temperature firing process, thereby improving the strength and toughness of the ceramic product. And by using the all-through preparation process to prepare the ceramic product, it can be used outdoors for a long time without discoloration, improving its durability.

[0065] In an embodiment of the present application, the composite ceramic green body is processed to obtain a wear-resistant ceramic tile, including:

[0066] The composite ceramic green body is dried, and the dried composite ceramic green body is sent to a roller hearth kiln for sintering to obtain a wear-resistant ceramic tile;

[0067] Among them, it is sintered for 15 - 25 min between room temperature and 700 °C, sintered for 8 - 15 min between 700 - 1050 °C, and held at 1050 °C for 3 - 6 min.

[0068] Specifically, the composite ceramic green body is dried in a drying kiln to obtain a green body with a certain strength; the green body is sent to a roller hearth kiln for firing to obtain a sintered ceramic product. The surface of the product out of the kiln is polished, and then after edge grinding, chamfering, air drying, inspection, color separation, grading, it is packed and stored in the warehouse. The water absorption rate of the finished product is below 0.1%.

[0069] In the sintering process of the embodiments of the present application, the sintering time in the high-temperature section is short. Since there is less organic matter and loss on ignition in the formulation system of the present application, and the formulation system contains a large amount of crystal structures, it provides favorable conditions for rapid low-temperature firing. At the same time, reducing the firing time in the high-temperature section can avoid the oxidation of the metal phase, thereby ensuring the performance of the product.

[0070] Through the above formulation system and preparation method, the embodiments of the present application can prepare a product with a strength of more than 80 MPa and a wear volume of less than 100 mm3 A wear-resistant ceramic tile with an elastic limit greater than 18 mm when the thickness is 6 mm, and the wear-resistant ceramic tile is applicable to outdoor ground places with large pedestrian flow such as subways and squares.

[0071] The embodiments of the present application achieve the following effects:

[0072] First, the ceramic tiles prepared in the embodiments of the present application have high strength, good toughness and good wear resistance, solving the problems that the cost of marble currently used for the ground of subways, stations, squares, etc. is relatively high, and the wear resistance of fully polished glaze ceramic products is relatively poor.

[0073] Second, the embodiments of the present application utilize a large amount of metallurgical slag to prepare ceramic tiles, which can greatly reduce the environmental pollution problems caused by the stacking of metallurgical slag and realize the utilization of solid waste.

[0074] Third, the embodiments of the present application utilize the compositional characteristics of metallurgical slag, change the traditional ceramic formula system based on mullite crystal phase, and propose a ceramic formula system of polycrystalline phase composite. The prepared ceramics have good toughness and high strength, with a strength greater than 80 MPa, while the strength of traditional ceramics is only about 40 MPa.

[0075] Fourth, the embodiments of the present application utilize the characteristics of many crystal phases and little loss on ignition in the composition of metallurgical slag, which can significantly reduce the sintering temperature and sintering time of ceramics, thereby greatly reducing energy consumption and providing a new direction for the low-carbon development of building ceramics.

[0076] Fifth, the embodiments of the present application utilize the compositional characteristics of metallurgical slag to solve the wettability problem between the metal phase and the non-metal phase, thereby providing a basic condition for strengthening and toughening building ceramics with the metal phase. Metal-non-metal composite ceramic tiles with high strength and good toughness can be prepared, thereby improving the toughness of ceramic tiles and enhancing the quality and market competitiveness of ceramic products.

[0130] The present invention provides a preparation method of a wear-resistant ceramic tile and the wear-resistant ceramic tile. The preparation method of the wear-resistant ceramic tile includes: pressing the prepared ceramic tile powder material and metal material into a composite ceramic green body, and the raw material formula of the ceramic tile powder material includes metallurgical slag; processing the composite ceramic green body to obtain a wear-resistant ceramic tile; among them, the raw materials of the metallurgical slag include 55-70 parts of vanadium-titanium slag and 10-20 parts of red mud by weight. In the embodiments of this application, adding metal materials to the ceramic tile powder material improves the toughness of the ceramic tile, and the metallurgical slag is mainly vanadium-titanium slag and red mud, which are metallurgical slags with a relatively high iron content and contain a large amount of metal oxides, and have good compatibility with metal materials, improving the wettability problem, thereby improving the performance of the wear-resistant ceramic tile. And because the metallurgical slag contains a large number of different types of crystal phases and the content of the glass phase is greatly reduced, various crystal phases in the composite ceramic green body are intertwined and connected during the high-temperature firing process, thereby improving the strength and toughness of the ceramic product.
