[0150] The products of Examples 1 - 3 and Comparative Examples 1 - 14 were subjected to performance tests, and the anti-slip performance (relative humidity 50%, pendulum anti-slip coefficient PTV), transparency, and cyan-white color property of the products were tested. The test results are shown in Table 1.

[0151] Table 1 Test results of the product performance of Examples 1 - 3 and Comparative Examples 1 - 14;

[0152]

[0153] It can be seen from Comparative Examples 1 - 14 and Examples 1 - 3 that the products of Example 3 have excellent anti-slip performance, excellent transparency performance, delicate product glaze, and cyan-white color.

When the modifier based on talc powder is not added, the anti-slip property of the product shows an obvious deteriorating trend. When the two are combined, they have a synergistic effect, and the performance effect of the product is the most significant.

[0159] When the alumina / quartz composite agent is not added during the preparation of the modified alumina agent, when the regulating liquid of the alumina / quartz composite agent does not contain the adjusted quartz stone, when the regulating liquid of the adjusted quartz stone does not contain quartz stone and kaolin, when the modifier is not added during the preparation of the modified alumina agent, when the urea solution and wollastonite are not added during the preparation of the modifier, and when strontium carbonate is not added during the preparation of the modifier, the performance of the product shows a deteriorating trend to varying degrees. The performance effect of the product is the most significant when the modifier obtained by the specific method of the present invention is combined with the alumina / quartz composite agent. Using other methods instead is not as obvious as the effect of the present invention.

[0160] When the sintered body is not added during the preparation of the modifier based on talc powder, and when cerium oxide and nano-titanium dioxide are not added to the sintered body, the performance of the product also shows a deteriorating trend. At the same time, when the addition treatment liquid is not added during the preparation of the modifier based on talc powder, when magnesium aluminate spinel is not added to the addition treatment liquid, when hydroxyapatite, shell powder are not added to the addition treatment liquid, when sodium silicate solution and 4% sodium alginate solution by mass fraction are replaced by water in the addition treatment liquid, the performance of the product shows a deteriorating trend to varying degrees. For the addition treatment liquid obtained by different methods, the performance of the product shows a deteriorating trend. Only when the modifier based on talc powder obtained by the specific method of the present invention is used, the performance effect of the product is the most obvious.

[0161] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention.

[0162] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
