[0155] It can be seen from Comparative Examples 1 to 13 and Example 3 that when one of the functional modifiers and the additives without modified talc are not added to the product, the performance of the product shows an obvious deterioration trend. When the two are coordinately combined, the performance effect of the product is the most significant;

[0156] When barium titanate modifier is not added in the preparation of the functional modifier, barium titanate is not added in the preparation of the barium titanate modifier, the modification liquid is not added in the preparation of the barium titanate modifier, the preparation method of the modification liquid is different, lithium nepheline and aluminum nitride are not added, the functional blending liquid is not added in the preparation of the functional modifier, and carboxymethyl cellulose sodium and a 6.5% mass fraction of barium nitrate aqueous solution are not added in the functional blending liquid, the performance of the product shows a deterioration trend to varying degrees;

[0157] The barium titanate modifier prepared by combining the modification liquid obtained by the specific method of the present invention with barium titanate, and the functional modifier prepared by combining the functional blending liquid obtained by the specific method of the present invention with the barium titanate modifier have the most significant performance effect on the product;

[0158] At the same time, when the functional additive is not added to the functional blending liquid, the performance of the product also shows an obvious deterioration trend, and the functional additive has an obvious improvement trend on the performance of the product;

[0159] In the preparation of the additive for modified talc, no additive is added, boron nitride and cerium oxide are not added to the additive, no modified talc liquid is added in the preparation of the additive for modified talc, no flaky talc powder and alumina are added to the modified talc liquid, and the performance of the product shows a deteriorating trend to varying degrees. The additive for modified talc prepared with the modified talc liquid obtained by the specific method of the present invention in combination with the additive has the most remarkable performance effect, and the effect is not as obvious as that of the present invention when other methods are used instead.

[0160] Based on the fact that the functional additive has a great influence on the performance of the product, the test results of the influence of the functional additive on the product performance are further studied as follows:

[0161] Experimental Example 1.

[0162] The difference from Example 3 is that heat-treated cordierite is not added to the functional additive.

[0163] Experimental Example 2.

[0164] The difference from Example 3 is that ultrasonic treatment is not carried out by adding ultrasonic liquid to the functional additive.

[0165] Experimental Example 3.

[0166] The difference from Example 3 is that sodium lignosulfonate is not added to the ultrasonic liquid and water is used instead of the Tris-HCl buffer solution.

[0167] Experimental Example 4.

[0168] The difference from Example 3 is that nano-bentonite and nano-titanium dioxide are not added to the ultrasonic liquid.

[0169] The product performance tests of Experimental Examples 1-4 are as follows:

[0170]

[0171] It can be seen from Experimental Examples 1-4 that when heat-treated cordierite is not added to the functional additive and ultrasonic treatment is not carried out by adding ultrasonic liquid, the performance change trend of the product is relatively large. At the same time, when ultrasonic treatment is not carried out by adding ultrasonic liquid, the performance stability of the product deteriorates significantly under the long-term corrosion and weather resistance conditions;

[0172] In addition, when sodium lignosulfonate is not added to the ultrasonic liquid and water is used instead of the Tris-HCl buffer solution, and nano-bentonite and nano-titanium dioxide are not added to the ultrasonic liquid, the performance of the product shows a deteriorating trend to varying degrees. Only the functional additive prepared with the specific ultrasonic liquid of the present invention in combination with heat-treated cordierite has the most remarkable performance effect, and the effect is not as obvious as that of the present invention when other methods are used instead.
