[0154] The performance of the products of Examples 1-3 and Comparative Examples 1-11 was tested under normal conditions, and the performance test results are shown in Table 1.

[0155] Table 1: Performance test results of the products of Examples 1-3 and Comparative Examples 1-11 under normal conditions It can be concluded from Table 1 that the products of Examples 1-3 have excellent 48h Escherichia coli antibacterial rate, rebound rate and tensile strength performance, and the antibacterial, rebound rate and tensile strength performance of the products can be coordinated and improved. The product performances of Examples 1-3 are significantly better than those of Comparative Examples 1-11.

[0156] The test product was placed at -5°C for 6 hours, then at 65°C and 500 pphm ozone for 2 hours, and then at 340nm and 0.5W / m 2 The product was placed under a xenon lamp with a wavelength of .nm for 2 hours. The above is one cycle. The product was cycled 10 times to test its aging resistance and cold resistance stability. The test results are shown in Table 2.

[0157] Table 2: Test results of aging resistance and cold resistance stability of products of Examples 1-3 and Comparative Examples 1-11 It can be concluded from Table 2 that the product of Example 3 of the present invention has significant effects on the stability of the 48h Escherichia coli antibacterial rate, rebound rate and tensile strength performance of the product in an aging-resistant and cold-resistant environment;

[0158] From Comparative Examples 1-11 and Example 3, it can be seen that the performance of the products without adding a carbon nanotube-modified regulator or a flaky talc assembly agent has a significant deterioration trend. The performance effect of the products is most significant when the two are coordinated and work together.

[0159] The performance of the products tended to deteriorate when no modifying liquid was added in the preparation of the carbon nanotube-modified conditioning agent, no conditioning liquid was added in the preparation of the carbon nanotube-modified conditioning agent, no hydroxyapatite and nano-silica sol were added to the conditioning liquid, no chitosan solution was added to the conditioning liquid, and the lanthanum chloride solution was replaced by deionized water. Only when the modified liquid obtained by the method of the present invention was combined with the conditioning liquid of the present invention, the performance effect of the product was the most obvious.

[0160] The performance of the products of the flaky talc powder assemblies without adding yttrium-adjusted flaky talc, directly replacing the yttrium-adjusted flaky talc in the preparation of the flaky talc, not using self-adjusting agent treatment in the flaky talc powder assemblies, not adding nano-bentonite air-cooled to room temperature in the self-adjusting agent, and not adding nano-silicon dioxide and sodium lignin sulfonate solution in the self-adjusting agent all tend to deteriorate. The performance of the flaky talc powder assemblies obtained by different methods all tend to deteriorate to varying degrees. The performance effect of the product is most significant when the specific self-adjusting agent of the present invention is combined with the yttrium-adjusted flaky talc of the present invention, and the effect of other replacement methods is not as obvious as that of the present invention.

[0161] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.

The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
