[0148] The difference from Example 3 is that no boron nitride is added to the formulation.

[0149] Comparative Example 15:

[0150] The difference from Example 3 is that sodium carboxymethyl cellulose is not added to the formulation, and the barium nitrate solution is replaced by water.

[0151] The ceramic products prepared in Examples 1 to 3 and Comparative Examples 1 to 15 were subjected to conventional antibacterial, glossiness and antifouling performance tests. The test results are shown in Table 1.

[0152] Table 1 Performance test results of ceramic products of Examples 1 to 3 and Comparative Examples 1 to 15:

[0153]

[0154] It can be seen from comparative examples 1 to 15 and embodiments 1 to 3 that the ceramic product of embodiment 3 has an excellent antibacterial rate for Escherichia coli and a significant antibacterial durability effect. At the same time, the ceramic product has excellent gloss and anti-fouling grade performance. The antibacterial, gloss and anti-fouling properties of the ceramic product can achieve coordinated improvements.

[0155] The ceramic products prepared in Examples 1 to 3 and Comparative Examples 1 to 15 were immersed in 45°C water for 6 hours, then taken out, naturally dried, and then heated to 70°C at a rate of 3°C / min, kept warm for 12 hours, and finally placed at -5°C for 12 hours. Conventional antibacterial, glossiness and anti-fouling performance tests were then carried out, and the water resistance and temperature change stability of the ceramic products were tested. The test results are shown in Table 2.

[0156] Table 2 Performance test results of the ceramic products of Examples 1 to 3 and Comparative Examples 1 to 15 under water immersion and temperature change conditions:

[0157]

[0158] It can be seen from Comparative Examples 1 to 15 and Example 3 that the product of Example 3 has significant antibacterial, glossiness and antifouling performance stability under water immersion and temperature change conditions, indicating that the product has good water resistance and temperature change resistance stability;

[0159] It can be seen from Comparative Example 1, Comparative Example 10 and Example 3 that without adding modified quartz powder and balancing agent for blending flaky talc, the performance stability of the product deteriorates significantly. The synergistic effect of the two is the most obvious.

[0160] As can be seen from Comparative Examples 2 to 6 and Example 3, the performance of the products has a trend of varying degrees of deterioration when no quartz matrix liquid is added in the preparation of the modified quartz powder, no wollastonite modifying liquid is added to the quartz matrix liquid, no sodium lignin sulfonate solution and wollastonite are added to the wollastonite modifying liquid, no pretreated quartz powder is added to the quartz matrix liquid, and no pyrophyllite / nano-titanium dioxide compounding agent is added in the preparation of the modified quartz powder. At the same time, the performance of the product is significantly deteriorated when no pyrophyllite / nano-titanium dioxide compounding agent is added. The quartz matrix liquid prepared by the wollastonite modifying liquid obtained by the method of the present invention has the most significant product performance effect.

[0161] As can be seen from Comparative Examples 7 to 9 and Example 3, the pyrophyllite / nano-titanium dioxide compounding agent was not added with pyrophyllite, the pyrophyllite / nano-titanium dioxide compounding agent was not added with nano-titanium dioxide, and the pyrophyllite / nano-titanium dioxide compounding agent was not added with calcium nitrate solution and silane coupling agent KH550. The performance of the product also has different deterioration trends. The pyrophyllite / nano-titanium dioxide compounding agent obtained by the specific method of the present invention has the most obvious performance effect of the product;

[0162] It can be seen from Comparative Examples 11 to 15 and Example 3 that when no flaky talc liquid is added in the preparation of the balancing agent for blending flaky talc, and no formulating agent is added in the preparation of the balancing agent for blending flaky talc, the performance of the product tends to deteriorate. When no nano-mica powder is added to the formulating agent, no boron nitride is added to the formulating agent, no sodium carboxymethyl cellulose is added to the formulating agent, and the barium nitrate solution is replaced by water, the performance of the product also tends to deteriorate to varying degrees. The balancing agent for blending flaky talc obtained by the formulating agent obtained by the specific method of the present invention and the flaky talc liquid has the most significant performance effect, and the replacement by other methods is not as obvious as the effect of the present invention.

[0163] 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 present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.

[0164] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description 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 may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
