When the functional additive and the modified nano titanium dioxide agent are coordinated and formulated together, the product performance effect is most significant.

[0170]

[0171] As can be seen from Experimental Examples 1 to 5, when aluminum silicate fiber is not added to the modifying liquid, the performance change trend of the product is relatively large. At the same time, when silicon carbide is not added to the modifying liquid and boron nitride is not added to the modifying liquid, the performance of the product also shows an obvious deterioration trend. Also, when nano-silica sol is not added to the modifying liquid and the yttrium nitrate solution in the modifying liquid is replaced with water, the performance of the product all shows a deterioration trend. The performance effect of the product is the most remarkable with the modifying liquid obtained by the specific method of the present invention, and the effect of using other methods to replace is not as obvious as that of the present invention.

[0172] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. 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 encompassed within the present invention.

[0173] 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.
