The above was one cycle, and the test was repeated 5 times to test the acid and alkali stability of the products. The test results are shown in Table 1.

[0172] Table 1 Product performance test results of Examples 1 to 3 and Comparative Examples 1 to 11:

[0173]

[0174] It can be seen from Comparative Examples 1-11 and Examples 1-3 that the product of Example 3 has excellent bending strength, and also excellent wear resistance and glossiness performance, and the three can be improved in a coordinated manner. In addition, the product has excellent stability performance under acid and alkali resistance conditions;

[0175] The present invention does not add a reinforcing agent based on the modification liquid adjustment and does not add a modified basalt fiber agent, and the performance of the product deteriorates significantly, and the performance stability of the product deteriorates significantly under acid and alkali resistance conditions; the two are used in combination, and the synergistic effect of the product is the most significant;

[0176] The performance of the products tended to deteriorate to varying degrees when no reinforcing agent was added to the reinforcing agent prepared based on the modification liquid, no plasma-treated pyrophyllite was added to the reinforcing agent, no zirconium oxide reinforcing liquid was added to the reinforcing agent, no modifying liquid was added to the reinforcing agent prepared based on the modification liquid, and the preparation methods of the modifying liquid were different;

[0177] The reinforcing agent prepared by the specific method of the present invention and the modifying liquid obtained by the method of the present invention is the most significant product. Other methods are not as significant as the present invention.

[0178] The performance of the products without adding basalt fiber agent, without adding S101 basalt fiber, without adding tetrabutyl titanate, replacing cobalt nitrate solution with water, and without adding ball milling additives in the preparation of modified basalt fiber agent all showed different degrees of deterioration trend. The performance deterioration trend was the greatest in the preparation of modified basalt fiber agent without adding ball milling additives.

[0179] The basalt fiber agent obtained by the specific method of the present invention is combined with a ball milling additive, and the product performance effect is the most significant. Other methods are not as obvious as the effect of the present invention.

[0180] The present invention further explores the product performance through the composition of ball milling additives.

[0181] Experimental Example 1:

[0182] The only difference from Example 3 is that silicon carbide is not added to the ball milling additive.

[0183] Experimental Example 2:

[0184] The only difference from Example 3 is that no nano-hydroxyapatite is added to the ball milling additive.

[0185] Experimental Example 3:

[0186] The only difference from Example 3 is that no calcined zinc oxide solution is added to the ball milling additive.

[0187] Experimental Example 4:

[0188] The only difference from Example 3 is that the calcined zinc oxide solution is directly replaced by nano zinc oxide.

[0189] Experimental Example 5:

[0190] The only difference from Example 3 is that the cerium nitrate solution is replaced by water.

[0191] The products of Experimental Examples 1 to 5 were subjected to conventional performance tests, and were placed at 70°C for 12 hours, then placed under 5% hydrochloric acid mist conditions for 24 hours, and placed under 5% sodium hydroxide alkaline mist conditions for 24 hours. The above was one cycle, and the test was repeated 5 times to test the acid and alkali stability of the products. The test results are shown in Table 2.

[0192] Table 2 Product performance test results of Experimental Examples 1 to 5:

[0193]

[0194] It can be seen from Experimental Examples 1-5 that calcined zinc oxide liquid and silicon carbide are not added to the ball milling additive, and the performance of the product changes. Among the components of the ball milling additive, the conventional performance and acid and alkali resistance stability deteriorate most significantly, followed by the fact that nano-hydroxyapatite is not added to the ball milling additive, the calcined zinc oxide liquid is directly replaced by nano-zinc oxide, and the cerium nitrate solution is replaced by water. The performance of the product has a tendency to deteriorate. The raw materials of the ball milling additive composition change, and the performance of the product has a tendency to deteriorate. The use of other methods to replace the composition of the ball milling additive is not as significant as the effect of the present invention. The composition of the ball milling additive of the present invention is unique.
