Description

Technical Field

[0001] This invention relates to the technical field of marble ceramic tiles, and in particular to a ceramic tile body with high drying strength, its preparation method, and marble ceramic tiles. Background Technology

[0002] To more realistically reproduce the surface texture of natural marble tiles, screen printing technology is used to enrich the surface effect and layering of marble tiles. In order to meet various process requirements during production and ensure that there are no cracked tiles on the production line, the dry body strength requirement is extremely high (dry body strength ≥ 1.8MPa). In order to ensure the strength of the body, the raw materials of the body are made by introducing raw ore to achieve the required dry body strength.

[0003] Because the drying strength of the ceramic tile body is required to be high, a high proportion of raw ore is used in the raw materials to ensure the drying strength of the body. However, due to the increasing scarcity of raw ore and the current high restrictions on mining (making stable supply difficult in the long run), the drying strength of marble ceramic tile bodies is difficult to guarantee. In addition, because raw ore contains a lot of organic matter, it is difficult to exhaust air during the production process, which makes marble ceramic tiles prone to black core, which is very unfavorable to increasing the production capacity of marble ceramic tiles.

[0004] Therefore, this application provides a ceramic tile body with high drying strength, a method for preparing the same, and a marble ceramic tile. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this invention provides a high-dry-strength ceramic tile body, its preparation method, and marble ceramic tiles. By adding brick base powder to replace the original ore clay, the ceramic tile body achieves higher dry-strength and meets the process standards for screen printing. This will reduce the use of non-renewable resources and achieve the goal of sustainable development.

[0006] The technical solution adopted by this invention to solve its technical problem is:

[0012] Furthermore, the medium-temperature sand is one or more of potassium sand, sodium sand, and red sand.

[0013] Furthermore, the waste material is one or more of polishing slag, recycled scrap, and sewage mud.

[0014] Furthermore, the magnesium oxide content in the brick base powder is 65-80% by weight.

[0015] A second objective of this application is to provide a method for preparing a ceramic tile blank, comprising the following steps:

[0016] Prepare the corresponding raw materials according to the weight composition of the ceramic tile body; after the raw materials are fully mixed, they are ball-milled; after ball milling, they are granulated; after granulation, they are aged, dried and fired to obtain the ceramic tile body.

[0017] Furthermore, the ball milling involves mixing the mixture, water, and desiccant, and then ball milling them in a small ball mill jar.

[0018] Furthermore, after granulation, the particle size distribution is as follows: 20 mesh ≤ 2.0%, 20-40 mesh 51-56%, 40-60 mesh 34-38%, 60-100 mesh ≤ 10%, and 100 mesh ≤ 3%.

[0019] A third objective of this application is to provide a marble ceramic tile with high drying strength, comprising the ceramic tile body described above.

[0030] To ensure the strength of the billet, raw ore is often introduced into the billet to achieve the required dry billet strength. The chemical composition of the raw ore is as follows:

[0031] The composition of the raw ore is as follows: SiO2: 59.58%, Al2O3: 25.98%, Fe2O3: 1.55%, TiO2: 0.26%, CaO: 0.26%, MgO: 0.3%, K2O: 1.5%, Na2O: 0.22%, and loss on ignition: 10.35%. Moreover, the raw ore contains a lot of tree roots, resulting in a lot of wood residue after ball milling. This makes it difficult to ventilate during the production process, which can easily cause the marble tiles to develop a black core.

[0032] To reduce the use of raw clay, this application provides a ceramic tile body with high dry strength by replacing raw clay with brick base powder, comprising the following raw materials by weight:

[0033] Stone powder 40-50 parts, washed clay 20-25 parts, medium-temperature sand 28.8-35 parts, waste material 10-12 parts, brick base powder 1.2-2 parts.

[0034] Specifically, the stone powder is one or both of potassium feldspar and sodium feldspar. In this application, the stone powder acts as a flux. The weight range of the stone powder is 40-50 parts, specifically any value among 40, 41, 45, and 50 parts, or any value within the range of 40-50 parts.

[0035] Specifically, the chemical composition of the water-washed mud is as follows:

[0036] The composition of the washed clay is as follows: SiO2: 50.98-65.5%, Al2O3: 34.04-39.9%, Fe2O3: 1.3-1.5%, TiO2: 0.06%, CaO: 0.25%, MgO: 0.15-0.25%, K2O: 1.38%, Na2O: 0.12%. In this application, the washed clay can enhance the drying strength of the ceramic tile, ensure its hardness during operation before sintering, and improve the physical properties of the product. The weight range of the washed clay is 20-25 parts, specifically any value from 20, 21, 22, or 25 parts, or any value within the range of 20-25 parts.

[0037] Specifically, the medium-temperature sand is one or more of potassium sand, sodium sand, and red sand. In this application, the medium-temperature sand serves to regulate the firing temperature, increase the sintering strength, and reduce costs. The weight range of the medium-temperature sand is 28.8-35 parts, specifically any value among 28.8, 29, 30, and 35 parts, or any value within the range of 28.8-35 parts.

[0038] Specifically, the waste material is one or more of polishing slag, recycled scrap, and sewage mud. The purpose of using the waste material is to utilize waste and reduce costs. The weight range of the waste material is 10-12 parts, specifically any value of 10, 11, or 12 parts, or any value within the range of 10-12 parts.

[0039] More specifically, polishing slag refers to the excess material after the semi-finished product has been ground and then pressed; the chemical composition of polishing slag is as follows:

[0040] SiO2: 68.71%, Al2O3: 20.04%, Fe2O3: 0.78%, TiO2: 0.15%, CaO: 0.79%, MgO: 1.1%, K2O: 3.65%, Na2O: 2.91%, Loss on ignition: 1.87%.

[0041] Recycled scrap refers to the collection of powder leakage from the raw material workshop and pressing workshop, as well as scrap after glazing on the glazing line; the chemical composition of recycled scrap is as follows:

[0042] SiO2: 69.62%, Al2O3: 20.12%, Fe2O3: 0.74%, TiO2: 0.13%, CaO: 0.63%, MgO: 0.89%, K2O: 3.6%, Na2O: 2.69%, Loss on ignition: 1.58%.

[0043] Wastewater cement refers to slurry leakage during the raw material workshop's slurry processing and the powder that flows into the wastewater treatment pond after washing and pressing. The chemical composition of wastewater cement is as follows:

[0044] SiO2: 65.91%, Al2O3: 20.27%, Fe2O3: 0.84%, TiO2: 0.23%, CaO: 0.86%, MgO: 0.97%, K2O: 3.51%, Na2O: 2.46%, Loss on ignition: 4.95%.

[0045] Specifically, the magnesium oxide content in the brick base powder is 65-80% by weight. In this application, the role of the brick base powder in the green body is to increase the drying strength of the green body and to act as a flux. The weight range of the brick base powder is 1.2-2 parts, specifically any value among 1.2 parts, 1.3 parts, 1.5 parts, and 2 parts, or any value within the range of 1.2-2 parts.

[0046] The chemical composition of brick base powder is as follows:

[0047] SiO2: 8.62-15%, Al2O3: 1.64-3%, Fe2O3: 0.99-2%, TiO2: 0.22-0.5%, CaO: 3.14-8%, MgO: 65-80%, K2O: 0.55-1%, Na2O: 0.02-0.05%.

[0048] A second objective of this application is to provide a method for preparing a ceramic tile blank, comprising the following steps:

[0049] Prepare the corresponding raw materials according to the weight composition of the ceramic tile body; after the raw materials are fully mixed, they are ball-milled; after ball milling, they are granulated; after granulation, they are aged, dried and fired to obtain the ceramic tile body.

[0050] Furthermore, the ball milling involves mixing the mixture, water, and desiccant, and then ball milling them in a small ball mill jar. The dispersant's function is to reduce viscosity and address the poor flowability of the slurry.

[0051] Furthermore, after granulation, the particle size distribution is as follows: 20 mesh ≤ 2.0%, 20-40 mesh 51-56%, 40-60 mesh 34-38%, 60-100 mesh ≤ 10%, and 100 mesh ≤ 3%. Particle size distribution refers to the quantity and size distribution of various particles in the powder. If the particles are too large, the dry blank strength will be lower and the shrinkage will be smaller. If the particles are too small, the dry blank strength will be higher, but it will be easy to separate into layers and the shrinkage will be larger. Both excessively large and small particles will affect the degree of sintering. The particle size distribution described in this application can ensure that the blank has good dry blank strength.

[0062] The requirements for testing ball mill slurry are: fineness 1.8-2.3% (250 mesh sieve), slurry moisture 32-36%, specific gravity 1.68-1.73, and flow rate 40-90 seconds.
