[0065] The products of Examples 1 to 3 and Comparative Examples 1 to 8 were tested for anti-slip performance, strength, and toughness under normal conditions, as well as under sunlight resistance and water resistance conditions. The sunlight resistance and water resistance conditions were as follows: the products were exposed to the sun for 10 days in July during summer and then immersed in water for 10 days. The test results are shown in Table 1.

[0066] Table 1 Test results of the product performance of Examples 1 to 3 and Comparative Examples 1 to 8:

[0067] It can be seen from Comparative Examples 1 - 8 and Examples 1 - 3 that the product of Example 3 has excellent anti-slip performance, and at the same time, it has excellent impact resistance and fracture toughness performance. The product can achieve excellent anti-drop and anti-slip properties. In addition, the product has excellent stability under sunlight resistance and water resistance conditions; If one of the zirconia agent doped with aluminosilicate fiber and the boron nitride additive is not added in the present invention, the performance of the product deteriorates significantly. When the two are used in harmony and coordination, the performance effect is the most significant; In the preparation of the zirconia agent doped with aluminosilicate fiber, modified carbon nanotube spheres were not added during ball milling. In the preparation of modified carbon nanotubes, nano-titanium oxide and magnesium oxide were not added.

Especially when the second-stage ball milling treatment with aluminosilicate fiber liquid is not used, the performance of the product deteriorates more significantly. In addition, the performance effect of the product is the most significant when the modified carbon nanotube spheres and aluminosilicate fiber liquid obtained by the specific method of the present invention are used to prepare the zirconia agent doped with aluminosilicate fiber; In addition, when the additive modification liquid is not added during the preparation of the boron nitride additive, the change in the performance of the product is also relatively obvious.

[0074] Table 2 Product performance test results of Experimental Examples 1 to 4:

[0075] It can be seen from Experimental Examples 1 to 4 that when sodium silicate and mica powder are not added in the preparation of the modification liquid, the performance of the product deteriorates significantly under sunlight and water resistance conditions. At the same time, when silicon nitride nanowhiskers are not added in the modification liquid, the performance change of the product is also obvious. When spodumene is not added in the modification liquid and water is used instead of lanthanum chloride solution, the performance of the product also shows a deteriorating trend to varying degrees. Only when the modification liquid prepared by the method of the present invention is used, the performance effect of the product is the most significant. When other methods are used instead, the effects are not as significant as that of the present invention. In the preparation of the modification liquid of the present invention, the composition components are unique, and using other methods instead is not as effective as the present invention.
