[0085] Comparative Example 1.

[0086] The difference from Example 3 is that the wollastonite-coordinated yttrium nitrate composite modified nano-graphene agent is not added.

[0087] Comparative Example 2.

[0088] The difference from Example 3 is that the wollastonite-coordinated yttrium nitrate composite modified nano-graphene agent is a mixture of graphene and wollastonite in a weight ratio of 5:1.

[0089] Comparative Example 3.

[0090] The difference from Example 3 is that the preparation method of the wollastonite-coordinated yttrium nitrate composite modified nano-graphene agent is different; the yttrium nitrate solution is not added to the wollastonite-coordinated yttrium nitrate solution.

[0091] Comparative Example 4.

[0092] The difference from Example 3 is that the preparation method of the wollastonite-coordinated yttrium nitrate composite modified nano-graphene agent is different, and the wollastonite is not added to the wollastonite-coordinated yttrium nitrate solution.

[0097] The performance measurement results of Examples 1-3 and Comparative Examples 1-6 are as follows

[0098]

[0099] It can be obtained from Examples 1-3 and Comparative Examples 1-6 that the product of the present invention itself has excellent wear resistance and anti-fouling effect, and at the same time, the wear resistance and anti-fouling can achieve a coordinated effect, and the performance of the prepared product can achieve a coordinated and significant improvement in wear resistance and anti-fouling; if one of the wollastonite-coordinated yttrium nitrate composite modified nano-graphene agent and the glass fiber blending whisker agent is not added, the performance of the product will be significantly reduced. The wollastonite-coordinated yttrium nitrate composite modified nano-graphene agent and the glass fiber blending whisker agent are coordinated and synergistic, and the performance of the product can reach a coordinated optimization;

[0100] It is also found that for the wollastonite-coordinated yttrium nitrate composite modified nano-graphene agent prepared by mixing graphene and wollastonite in a weight ratio of 5:1, without adding yttrium nitrate solution to the wollastonite-coordinated yttrium nitrate solution and without adding wollastonite to the wollastonite-coordinated yttrium nitrate solution, the performance of the product shows a deteriorating trend.
