Description

Technical Field

[0002] Far-infrared emitting ceramics not only activate food, beverages, and water, but also offer health benefits to the human body. Far-infrared rays are invisible electromagnetic waves with wavelengths between microwaves and visible light. Infrared rays can be divided into near-infrared (wavelength 1-3μm), mid-infrared (wavelength 3-5μm), and far-infrared (wavelength 8-14μm). Far-infrared rays themselves possess disinfection, sterilization, and activation functions, and are mainly used in far-infrared health products.

[0003] Existing daily-use ceramic products have poor far-infrared emissivity and heating performance. At the same time, it is difficult to coordinate and improve the product's gloss with far-infrared emissivity and heating performance, which limits the product's efficiency. Furthermore, the product's poor stability under humidity and hot-cold cycle conditions further restricts its use. Summary of the Invention

The product also exhibits significant stability under humidity and hot / cold cycling conditions. The cerium-modified Bianstone powder is formulated using fly ash, silane coupling agent KH550, and sodium lignosulfonate solution to form a first grinding agent. A second grinding agent is prepared using lignocellulose, stearic acid, and dopamine hydrochloride solution. The grinding fluid is obtained by combining the first and second grinding agents. The fly ash in the grinding fluid, combined with lignocellulose and other raw materials such as the silane coupling agent, optimizes and improves the Bianstone powder, allowing for better coordination between the Bianstone grinding fluid and the cerium additive. The cerium additive is formulated using zirconium oxide, sodium silicate solution, and magnesium oxide. As a matrix agent, cerium oxide and lanthanum chloride solutions are blended and then cerium additives are formulated. The resulting cerium additives enhance the synergistic effect between Bianstone powder and the matrix in the Bianstone ball milling slurry system, thereby further enhancing the system's gloss, far-infrared emissivity, and heat generation, as well as optimizing the product's stability under humidity and thermal cycling conditions. The modified titanium dioxide agent is prepared by using titanium dioxide with sodium alginate solution to optimize the dispersion of nano-titanium dioxide. Simultaneously, sodium dodecylbenzenesulfonate, silicon carbide, boron oxide, and a 5% (w / w) chitosan solution are thoroughly mixed to obtain a modifier. The modifier is used to improve the nano-titanium dioxide slurry. Through the blending and formulation of raw materials, silicon carbide and boron oxide are used to improve the nano-titanium dioxide. The resulting modified titanium dioxide agent has an enhanced synergistic effect with the cerium-added modified Bianstone powder, thereby further improving the product's performance and significantly enhancing its stability under humidity and thermal cycling conditions.

[0142] Comparative Example 7:

[0144] Comparative Example 8:

[0154] The ceramic products of Examples 1-3 and Comparative Examples 1-12 were tested for gloss, far-infrared emissivity, and heating properties. The products were placed under 50% humidity and 2°C for 12 hours, then heated to 75°C at a rate of 2°C / min and held for 12 hours. This was one cycle, and the cycle was repeated 5 times to test the stability of each property of the products under humidity and thermal cycling conditions. The test results are shown in Table 1.

[0155] Table 1. Product performance test results of Examples 1-3 and Comparative Examples 1-12:

[0156]

[0157]

[0158] As can be seen from Comparative Examples 1-12 and Examples 1-3, the product of Example 3 has excellent far-infrared emissivity, temperature rise and gloss, and the product has excellent stability in humidity and hot and cold cycle treatment.

[0159] As can be seen from Comparative Example 1, Comparative Example 10 and Example 3, the performance of the product is significantly reduced when neither cerium-modified Bianstone powder nor modified titanium dioxide agent is added.

[0160] As can be seen from Comparative Examples 2-4, Comparative Example 9, and Example 3, the performance of the modified Bianstone powder with cerium addition tends to deteriorate when Bianstone ball milling fluid is not added during ball milling, when Bianstone powder is not added to the ball milling fluid, when Bianstone powder is not subjected to primary ball milling treatment with ball milling fluid during the preparation of Bianstone ball milling fluid, and when cerium additive is not added during the preparation of modified Bianstone powder with cerium addition. The performance of the product is most significantly improved when a specific Bianstone ball milling fluid is used in combination with cerium additive, and the performance of the product deteriorates significantly when cerium additive is not added during the preparation of modified Bianstone powder with cerium addition.

[0161] As can be seen from Comparative Examples 5-8 and Example 3, the performance of the products deteriorated to varying degrees when the first grinding agent was not added to the ball milling fluid, when fly ash and silane coupling agent KH550 were not added to the first grinding agent, when the second grinding agent was not added to the ball milling fluid, and when lignocellulose and stearic acid were not added to the second grinding agent. The ball milling fluid prepared using the first grinding agent and the second grinding agent obtained by the specific method of this invention showed the most significant performance improvement.

[0162] As can be seen from Comparative Examples 11-12 and Example 3, in the preparation of modified titanium dioxide, if no modifier is added in step S13, or if silicon carbide and boron oxide are not added to the modifier, the performance of the product will deteriorate. The modified titanium dioxide modified by the modifier obtained by the specific method of this invention has a significant effect on product performance.

[0163] Based on the above performance tests, this invention further explores the product performance using cerium additives.

[0164] Experimental Example 1:

[0165] Same as Example 3, except that zirconium oxide was not added to the cerium additive.

[0166] Experimental Example 2:

[0167] Same as Example 3, except that zirconium oxide was not added to the zirconium oxide agent.

[0168] Experimental Example 3:

[0169] Same as Example 3, except that magnesium oxide was not added to the zirconium oxide agent.

[0170] Experiment Example 4:

[0171] Same as Example 3, except that sodium silicate solution was not added to the zirconium oxide agent.

[0172] Experimental Example 5:

[0173] Same as Example 3, except that cerium oxide was not added during the preparation of the cerium additive.

[0174] Experimental Example 6:

[0175] Same as Example 3, except that water was used instead of lanthanum chloride solution.

[0176] The ceramic products in routine tests 1-6 were tested for gloss, far-infrared emissivity, and heating properties. The products were placed in a 50% humidity environment and kept at 2°C for 12 hours. Then, the temperature was increased to 75°C at a rate of 2°C / min and held for 12 hours. This was one cycle, and the cycle was repeated 5 times to test the stability of each property of the products under humidity and thermal cycling conditions. The test results are shown in Table 2.

[0177] Table 2 shows the product performance test results for Experiment Examples 1-6:

[0178]

[0179]

[0180] As can be seen from Experiments 1-6, the absence of zirconium oxide in the cerium additive resulted in the most significant deterioration in product performance among the factors affecting the preparation of the cerium additive. The absence of zirconium oxide, magnesium oxide, or sodium silicate solution in the zirconium oxide additive all led to varying degrees of performance degradation. The use of the specific zirconium oxide agent of this invention resulted in the best product performance. Furthermore, the absence of cerium oxide and the substitution of water for lanthanum chloride solution in the preparation of the cerium additive also resulted in performance degradation. In the preparation of the cerium additive, all raw materials are indispensable, and the effects of other raw material ratios are not as significant as those of this invention.

[0181] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
