Description

Technical Field

[0001] This invention belongs to the field of ceramic manufacturing technology, specifically relating to a ceramic clay and its preparation method. Background Technology

[0002] Ceramic clay, also known as ceramic mortar, is a widely used material in ceramic production. Its main characteristics include high binding strength, plasticity, and good sintering properties. When fired at high temperatures, ceramic clay can form porcelain products with high hardness, a fine texture, and a translucent appearance.

[0003] Ceramic clay generally consists of inorganic non-metallic materials, binders, water, and other auxiliary materials. Inorganic non-metallic materials are further divided into: plastic raw materials, including clays such as Datong clay, which mainly play a role in plasticization and bonding during production and are crucial for ceramic forming; lean raw materials, including quartz minerals; and fluxing raw materials, including potassium feldspar minerals. The basic requirements for ceramic clay are that the particle size of the inorganic non-metallic materials must be controlled between several micrometers and tens of micrometers, with uniform particle distribution, no agglomeration, low binding strength, and good fluidity. The balance between viscosity and fluidity is critical.

[0004] Most of the binders in existing ceramic clay are organic materials. Although they play a corresponding role in bonding and plasticizing, the decomposition of organic materials during sintering will lead to a decrease in the overall density of the ceramic clay and an increase in porosity, which in turn will reduce the strength of the finished product. Summary of the Invention

[0005] The purpose of this invention is to provide a ceramic clay and its preparation method to solve the problem of low strength in existing ceramic clay products using organic materials as binders.

[0006] The objective of this invention can be achieved through the following technical solutions: A ceramic clay material includes a clay base, a dispersant, a zirconium phosphate-based reinforcing component, an organic-inorganic hybrid binder, and water. The zirconium phosphate-based reinforcing component accounts for 3-8% of the clay base, the dispersant accounts for 0.1-0.3% of the clay base, the organic-inorganic hybrid binder accounts for 1-5% of the clay base, and the water accounts for 30-35% of the clay base.

[0007] The clay base material comprises the following raw materials in parts by weight: 32-41 parts Datong clay, 6-10 parts potassium feldspar, 15-20 parts quartz, 20-25 parts clay, 3-5 parts dolomite, and 0.5-1 parts barium carbonate.

[0008] The organic-inorganic hybrid adhesive is sodium carboxymethyl cellulose in situ grafted with nano zinc oxide.

[0009] Furthermore, the organic-inorganic hybrid adhesive is prepared through the following steps: Sodium carboxymethyl cellulose was added to an aqueous solution of zinc nitrate hexahydrate and stirred until homogeneous to obtain mixture a. An aqueous solution of triethanolamine was added to anhydrous ethanol to obtain mixture b. Mixtures a and b were added to a mixing tank and stirred for 1 hour. The mixture was then transferred to a polytetrafluoroethylene reactor and rapidly heated to 180°C at 600W for 15 minutes using a microwave digester. After cooling to room temperature, the mixture was centrifuged. The precipitate was washed three times with ethanol and deionized water and dried at 60°C to constant weight. In the above process, the ratio of zinc nitrate hexahydrate aqueous solution, sodium carboxymethyl cellulose, triethanolamine aqueous solution, and anhydrous ethanol is 100mL:0.1-0.5g:100mL:10-100mL. The concentration of zinc nitrate hexahydrate aqueous solution is 0.01-0.06mol / L, and the concentration of triethanolamine aqueous solution is 1.2mol / L. Using zinc nitrate hexahydrate and triethanolamine as raw materials, nano-ZnO is prepared by microwave hydrothermal method. At the same time, sodium carboxymethyl cellulose is introduced in situ for graft modification to obtain an organic-inorganic hybrid adhesive.

[0010] Furthermore, the zirconium phosphate-based reinforcing component is prepared through the following steps: Carboxyl-containing polycarbosilane was added to xylene to obtain mixture c. Nano-silver-loaded zirconium phosphate was dispersed in a flask containing anhydrous ethanol. Mixture c was added dropwise to the flask at 45°C. After the addition was completed, the mixture was stirred and kept warm for 2 hours. After cooling to room temperature, it was filtered, and the filter cake was washed and dried to obtain the zirconium phosphate-based reinforcing component.

[0011] Furthermore, the ratio of carboxyl-containing polycarbosilane, xylene, nano-silver-loaded zirconium phosphate, and anhydrous ethanol is 1-2g: 10-20mL: 10g: 100-150mL.

[0012] The surface of nano-silver-loaded zirconium phosphate is modified with carboxyl-containing polycarbosilane, which binds to the nano-silver-loaded zirconium phosphate through hydrogen bonding and other interactions. This improves the dispersibility of the nano-silver-loaded zirconium phosphate in ceramic clay and, as a precursor to SiC fibers, forms the SiC phase in the ceramic product during the sintering process, thereby increasing the strength of the ceramic product.

[0013] Furthermore, the carboxyl-containing polycarbosilane is prepared by the following steps: After mixing polycarbosilane and tetrahydrofuran, transfer the mixture to a flask, heat it to 80°C under nitrogen protection, add acrylic acid and chloroplatinic acid, stir and heat to 100-120°C, keep the temperature for 8-20 hours, and after the reaction is completed, remove the tetrahydrofuran by vacuum distillation. In the above reaction, the mass ratio of polycarbosilane to acrylic acid is 1:0.2-0.5, and the amount of chloroplatinic acid is 0.002% of the total mass of polycarbosilane and acrylic acid. The polycarbosilane containing Si-H bonds and the base material undergo a hydrosilylation reaction with the acrylic acid containing C=C bonds to obtain a carboxyl-containing polycarbosilane.

[0014] Furthermore, the M of polycarbosilane n Its concentration is 1084-1387 g / mol, its molecular weight (Mw) is 2492-7963 g / mol, and its softening point is 206-260℃.

[0015] Furthermore, the dispersant is any one or more of glycerol, trioleic acid glyceride, and triethanolamine.

[0016] The method for preparing the above-mentioned ceramic clay includes the following steps: According to the formula ratio, Datong clay, potassium feldspar, quartz, clay, dolomite, barium carbonate, dispersant, zirconium phosphate-based reinforcing component, organic-inorganic hybrid binder, and water are added to a ball mill jar and ball milled using a planetary ball mill. The parameters of the planetary ball mill are set as follows: rotation speed 350-400 r / min, rotation time 10-20 min, to obtain slurry. The slurry is aged in a slurry tank at a temperature of 30-50℃ and a humidity of 60-80% for 40-60 hours. Then, the slurry is filtered at a pressure of 1.4-1.5 MPa to obtain mud cake. The mud cake is added to a ply mill and ply twice to obtain mud strips. The mud strips are aged in an aging chamber for 6-9 days at a temperature of 30-50℃ and a humidity of 60-80%, and then ply three more times. The moisture content of the pounded mud is 20-22 wt%, resulting in ceramic clay.

[0017] The beneficial effects of this invention are: This invention provides a ceramic clay material that uses sodium carboxymethyl cellulose in situ grafted with nano-zinc oxide as an organic-inorganic hybrid binder, replacing the existing pure organic binder sodium carboxymethyl cellulose. This not only provides excellent adhesion and plasticizing effects, but also, after high-temperature sintering, the nano-zinc oxide can compensate for the defects caused by the decomposition of sodium carboxymethyl cellulose, which helps to reduce the shrinkage rate of the ceramic clay material during sintering. In addition, the nano-zinc oxide also has good bactericidal properties, which can endow ceramic products with good antibacterial properties.

[0018] This invention also incorporates a zirconium phosphate-based reinforcing component into the ceramic clay, which is obtained by combining carboxyl-containing polycarbosilane and nano-silver-loaded zirconium phosphate. Carboxyl-containing polycarbosilane is introduced onto the surface of the nano-silver-loaded zirconium phosphate. First, it improves the dispersibility of nano-silver-loaded zirconium phosphate in ceramic clay, ensuring uniform dispersion within the ceramic matrix. Based on its high thermal stability, this imparts thermal stability, antibacterial properties, and mechanical strength to ceramic products. Second, it acts as an organic binder. During sintering, the carboxyl groups of carboxyl-containing polycarbosilane react with the hydroxyl groups of the organic-inorganic hybrid binder to generate an organic network. This network enhances the interaction between matrix particles, further increasing the density of the ceramic clay. Third, it serves as a SiC fiber precursor, forming a SiC reinforcing phase in ceramic products during sintering, thus improving the strength and thermal stability of the ceramic products.

[0044] Comparative Example 6 A ceramic clay, compared with Example 3, replaces the organic-inorganic hybrid binder in Example 3 with sodium carboxymethyl cellulose, while the other raw materials and preparation process are the same as in Example 3.

[0045] The ceramic clay materials obtained in Examples 3-5 and Comparative Examples 3-6 were placed in a strip mold and allowed to stand for 12 hours to form. The formed ceramic strips were dried at 110°C for 3 hours, then heated to 1150°C at a heating rate of 5°C / min and calcined for 3 hours. The temperature was then slowly lowered to room temperature to obtain the ceramic material. The shrinkage rate of the ceramic strips was tested.

The test results of Example 3 and Comparative Examples 5 and 6 show that the organic-inorganic hybrid binder in this case is more effective than the combination of nano-zinc oxide and sodium carboxymethyl cellulose or the use of sodium carboxymethyl cellulose alone.
