[0145] The difference from Example 3 is that in the preparation of the zirconium silicate performance regulator, the zirconium silicate liquid is made of zirconium silicate and water in a weight ratio of 2:5.

[0146] The products of Examples 1 to 3 and Comparative Examples 1 to 10 were tested for anti-skid, antibacterial and wear resistance under normal conditions. The products were immersed in 55°C water for 12 hours and then scrubbed 10 times with a load of 2N to test the water resistance and scrub resistance stability of the products. The test results are shown in Table 1.

[0147] Table 1 Product performance test results of Examples 1 to 3 and Comparative Examples 1 to 10:

[0148]

[0149] It can be seen from Comparative Examples 1 to 10 and Examples 1 to 3 that the product of Example 3 has an antibacterial rate, and at the same time has excellent anti-slip and wear resistance. The product can achieve coordinated improvement in antibacterial, anti-slip and wear resistance. In addition, the product has excellent performance stability under water resistance and scrub resistance conditions;

[0150] From Comparative Examples 1 to 10 and Example 3, it can be seen that the product performance has a significant trend of deterioration when neither the lanthanum-doped air knife soil modifier nor the zirconium silicate synergist is added. The lanthanum-doped air knife soil modifier and the zirconium silicate synergist are used in combination to achieve a significant performance effect of the product.

[0151] The performance of the products showed a trend of deterioration when the lanthanum modifying liquid was not used for the preparation of the lanthanum-doped air knife soil modifier, the lanthanum modifying liquid was not used for the modification liquid, the silane coupling agent KH560 and the sodium dodecylbenzene sulfonate solution were not added to the modification liquid, the aluminum borate whisker was not added to the modification liquid, and the air knife soil was not added to the preparation of the lanthanum-doped air knife soil modifier. The lanthanum-doped air knife soil modifier obtained by the lanthanum modifying liquid treatment and the air knife soil prepared by the modification liquid obtained by the method of the present invention had the most significant product performance effect. The performance of the product also showed a relatively obvious trend of deterioration when the aluminum borate whisker was not added to the modification liquid.

[0152] The zirconium silicate performance-enhancing agent is not treated with step S12, magnesium oxide and nano-silica sol are not added in the treatment of step S12, and the zirconium silicate liquid in the preparation of the zirconium silicate performance-enhancing agent is prepared by mixing zirconium silicate and water in a weight ratio of 2:5. The performance of the products tends to deteriorate. The product performance effect is most significant when the step S12 treatment is obtained by the specific method of the present invention.

[0153] The present invention finds that the aluminum borate whisker agent has a significant improvement effect on the performance of the product. Based on this, the product performance is further explored through the preparation of the aluminum borate whisker agent.

[0154] Experimental Example 1:

[0155] The only difference from Example 3 is that no heat-treated aluminum borate whiskers are added in the preparation of the aluminum borate whisker agent.

[0156] Experimental Example 2:

[0157] The only difference from Example 3 is that ultrasonic liquid treatment is not used in the preparation of the aluminum borate whisker agent.

[0158] Experimental Example 3:

[0159] The only difference from Example 3 is that no nano-alumina is added to the ultrasonic liquid.

[0160] Experimental Example 4:

[0161] The only difference from Example 3 is that stearic acid and sodium silicate solution are not added to the ultrasonic liquid.

[0162] Experimental Example 5:

[0163] The only difference from Example 3 is that no dopamine hydrochloride solution is added to the ultrasonic liquid.

[0164] The products of Experimental Examples 1 to 5 were tested for anti-skid, antibacterial and wear resistance under normal conditions. The products were immersed in 55°C water for 12 hours and then scrubbed 10 times with a load of 2N to test the water resistance and scrub resistance stability of the products. The test results are shown in Table 2.

[0165] Table 2 Product performance test results of Experimental Examples 1 to 5:

[0166]

[0167] It can be seen from Experimental Examples 1-5 that the performance of the product has a significant tendency to deteriorate when no heat-treated aluminum borate whisker is added in the preparation of the aluminum borate whisker agent. At the same time, the performance of the product also shows an obvious trend of change when ultrasonic liquid treatment is not used in the preparation of the aluminum borate whisker agent. In addition, when nano-alumina is not added to the ultrasonic liquid, stearic acid and sodium silicate solution are not added to the ultrasonic liquid, and dopamine hydrochloride solution is not added to the ultrasonic liquid, the performance of the product all has a tendency to deteriorate to varying degrees. The performance effect of the product using the ultrasonic liquid obtained by the specific method of the present invention in combination with the heat-treated aluminum borate whisker is the most significant, and the effects of other methods are not as obvious as those 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.
