Description

Technical Field

[0001] The present invention relates to the technical field of daily-use ceramics, and in particular to a high-temperature resistant daily-use ceramic product and a preparation method thereof. Background Art

[0002] The emergence of daily-use ceramics can be said to be driven by people's daily needs. The porcelain items that people encounter most often and are most familiar to them, such as tableware, tea sets, coffee sets, wine sets, and dining sets, are categorized by type. Currently, the main types of porcelain available on the market include fine daily-use porcelain, ordinary daily-use porcelain, stoneware, bone china, exquisite daily-use porcelain, underglaze (medium) colored daily-use porcelain, and fine pottery.

[0003] In order to enhance the antibacterial properties of existing daily-use ceramic products, nano-inorganic antibacterial particles are added. However, the nano-materials are prone to agglomeration, which in turn affects the performance of the product. In addition, the product is easily deformed under high temperature conditions and has poor high-temperature deformation resistance. At the same time, the product has poor anti-slip properties and the performance coordination of the product is not ideal. In addition, the product has poor washing stability, which limits the product's use efficiency. Summary of the Invention

Under the washing conditions, the products were washed 100 times with a 5% by mass sodium hypochlorite solution. The test results are shown in Table 1.

[0131] Table 1 Product performance test results of Examples 1 to 3 and Comparative Examples 1 to 11:

[0132]

[0133] From Comparative Examples 1-11 and Examples 1-3, it can be seen that the product of Example 3 has excellent antibacterial and anti-slip properties, as well as excellent high-temperature deformation resistance. The three can be improved in a coordinated manner. In addition, the product has excellent washing resistance and stability.

[0134] The present invention does not add either the boron-doped silicon nitride additive or the modifying functional agent, which significantly deteriorates the performance of the product. The combination of the two agents leads to a synergistic effect, which results in the most significant performance effect of the product.

[0135] No boron-containing enhancing fluid was added to the preparation of the boron-doped silicon nitride additive, no composite was added to the preparation of the boron-containing enhancing fluid, no bentonite and zirconium oxide were added to the composite, no boron-doped blending fluid was added to the preparation of the boron-containing enhancing fluid, no boron oxide and barium titanate were added to the preparation of the boron-doped blending fluid, and no silicon nitride additive was added to the preparation of the boron-doped silicon nitride additive. The performance of the products all showed a trend of deterioration to varying degrees, especially when no silicon nitride additive was added, the performance deterioration of the products was more obvious;

[0136] At the same time, the boron-containing synergistic liquid prepared by combining the complex obtained by the specific method of the present invention with a boron-doped blending liquid and a boron-doped silicon nitride additive is prepared, and the performance effect of the product is the most significant;

[0137] When no sintered body is added in the preparation of the modified functional agent, no functional liquid is added in the preparation of the modified functional agent, and basalt fiber and magnesium oxide are not added to the functional liquid, the performance of the product tends to deteriorate. The performance effect of the modified functional agent made by combining the functional liquid obtained by the specific method of the present invention with the sintered body is the most significant.

[0138] The present invention further explores the product performance through the preparation of silicon nitride additives.

[0139] Experimental Example 1:

[0140] The same as Example 3, except that no treatment liquid is added during the preparation of the silicon nitride additive.

[0141] Experimental Example 2:

[0142] The same as Example 3, except that no pretreated silicon nitride is added in the preparation of the silicon nitride additive.

[0143] Experimental Example 3:

[0144] The same as Example 3, except that mullite and yttrium oxide are not added to the treatment solution.

[0145] Experimental Example 4:

[0146] The same as Example 3, except that aluminum borate whiskers and illite are not added to the treatment solution.

[0147] The same performance test was performed on the products of Experimental Examples 1 to 4. The test results are shown in Table 2.

[0148] Table 2 Product performance test results of Experimental Examples 1 to 4:

[0149]

[0150] It can be seen from Experimental Examples 1-4 that when no pretreated silicon nitride and no treatment liquid were added in the preparation of the silicon nitride additive, the performance of the product deteriorated significantly. At the same time, no mullite and yttrium oxide were added to the treatment liquid, and no aluminum borate whiskers and illite were added to the treatment liquid. The performance of the product showed a trend of deterioration to varying degrees. The performance effect of the specific silicon nitride additive prepared by combining the treatment liquid obtained by the specific method of the present invention with pretreated silicon nitride was the most significant. The effects of other methods were not as obvious as those of the present invention.

[0151] 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 embodied 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 illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.

[0152] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. 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.
