[0069] Comparative Example 8: The difference from Example 3 is that no nano-silicon dioxide liquid is added to the modified regulator.

[0070] Comparative Example 9: The difference from Example 3 is that no chitosan solution and nano-silica sol are added to the nano-silica liquid.

[0071] Comparative Example 10: The difference from Example 3 is that no basalt fiber and sodium alginate agent are added to the modified regulator.

[0072] The products of Examples 1-3 and Comparative Examples 1-10 were subjected to conventional performance tests. The products were placed at -10°C for 48 hours and then placed in 2% hydrochloric acid for 24 hours. The above was one cycle. The cycle was repeated 10 times. The performance test results are shown in Table 1.

[0073] Table 1 Product performance test results of Examples 1-3 and Comparative Examples 1-10: It can be concluded from Examples 1-3 and Comparative Examples 1-10 that the product of Example 3 of the present invention has excellent anti-fouling grade, wear resistance and bending strength under normal conditions, and also has excellent performance stability under frost resistance and acid corrosion resistance conditions; The present invention does not add any of the linking agent doped with silicon nitride and the modifying regulator, and the performance of the product has a significant tendency to deteriorate. The two are coordinated and coordinated to achieve the most significant product performance effect. In the preparation of the silicon nitride doped linking agent, no silicon nitride doping liquid was added, no linking agent treatment was used in the preparation of the silicon nitride doped linking agent, no boron oxide agent was added to the linking agent, the boron oxide agent was replaced by boron oxide, and no nano mica powder and silane coupling agent were added to the linking agent. The performance of the product has a tendency to deteriorate. The silicon nitride doping liquid obtained by the specific boron oxide agent and linking agent treatment of the present invention has the most significant performance effect of the product. The use of other methods instead is not as obvious as the effect of the present invention. The performance of the product tends to deteriorate when the nano-silica liquid, chitosan solution and nano-silica sol are not added to the modified regulator, and the basalt fiber continuous sodium alginate agent is not added to the modified regulator. The performance effect of the product is most significant when the nano-silica liquid obtained by the method of the present invention is combined with the basalt fiber continuous sodium alginate agent. At the same time, the performance of the product deteriorates significantly when the basalt fiber continuous sodium alginate agent is not added. Based on the fact that basalt fiber combined with sodium alginate agent has a significant impact on the performance of the product, further research is needed.

[0074] Experimental Example 1: The only difference from Example 3 is that no preheated basalt fiber is added in the preparation of the basalt fiber-adjusted sodium alginate agent.

[0075] Experimental Example 2: The only difference from Example 3 is that no lanthanum chloride solution is added in the preparation of the basalt fiber continuous sodium alginate agent.

[0076] Experimental Example 3: The only difference from Example 3 is that no sodium alginate solution is added in the preparation of the basalt fiber continuous sodium alginate agent.

[0077] Experimental Example 4: The only difference from Example 3 is that the mass fraction of the lanthanum chloride solution is 3%, and the mass fraction of the sodium alginate solution is 6%.

[0078] The products of Experimental Examples 1-4 were subjected to conventional performance tests. At the same time, the products were placed at -10°C for 48 hours, and then placed in 2% hydrochloric acid for 24 hours. The above was one cycle. The cycle treatment was repeated 10 times. The performance test results are shown in Table 2.

[0079] Table 2 Product performance test results of Experimental Examples 1-4: It can be seen from Experimental Examples 1-4 that preheated basalt fiber is not added in the preparation of basalt fiber and sodium alginate agent. In the preparation of basalt fiber and sodium alginate agent, the performance of the product deteriorates most significantly. At the same time, the performance of the product tends to deteriorate when no lanthanum chloride solution and no sodium alginate solution are added. The performance of the product also tends to deteriorate when the mass fractions of lanthanum chloride solution and sodium alginate solution are different. Only when the specific raw materials and specific mass fractions of the present invention are used, the performance effect of the product is most significant. Other methods are not as obvious as the effect of the present invention.
