[0002] As an important material for arts and crafts, ceramics have a long history and rich cultural connotations. Although traditional ceramic handicrafts excel in aesthetics and artistry, they often lack wear resistance. Ordinary ceramic materials are brittle and hard, and scratches and wear easily appear on the surface, which not only affects the appearance of ceramic handicrafts, but also reduces their service life and collection value.

[0003] Existing ceramic handicraft materials have poor wear resistance, stain resistance and fracture toughness. The difficulty of the product lies in the balanced improvement of performance. At the same time, the product has poor light and weather resistance, which limits the product's efficiency. Summary of the Invention

[0138]

[0139] From Examples 1-3 and Comparative Examples 1-12, it can be concluded that the antifouling properties, fracture toughness, and wear resistance of the product of Example 3 of the present invention can be improved in a coordinated manner, and the light and weather resistance stability of the product are also significantly improved;

[0140] Without adding either the wear-resistant functional agent or the modified filler, the performance of the product showed a significant deterioration trend. The coordinated use of the two and their synergistic effect produced the most significant performance effect.

[0149] The same as Example 3, except that kaolin is not added to the filling liquid.

[0150] Experimental Example 3:

[0151] The same as Example 3, the only difference is that sodium hexafluoroaluminate is not added to the filling liquid.

[0152] Experimental Example 4:

[0153] The same as Example 3, except that no barium nitrate solution is added to the filling liquid.

[0154] The same performance test was performed on the products of Experimental Examples 1-4, and the test results are shown in Table 2.

[0155] Table 2 Product performance test results of Experimental Examples 1-4:

[0156]

[0157] As can be seen from Experimental Examples 1-4, when strontium titanate and kaolin were not added to the filling liquid, the product performance showed a trend of deterioration to varying degrees. At the same time, when sodium hexafluoroaluminate and barium nitrate solution were not added to the filling liquid, the product performance also showed a trend of deterioration. The filling liquid obtained by the specific method of the present invention had the most significant product performance effect. In the preparation of the filling liquid, all raw materials are indispensable. Only when the specific raw material ratio of the present invention is used is the effect most significant. The use of other raw material ratios is not as significant as the effect of the present invention.

[0158] 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.

[0159] 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.
