[0137] Comparative Example 10.

[0138] The difference from Example 3 is that no hydroxyapatite or urea is added to the regulating modifier.

[0139] The products of Examples 1-3 and Comparative Examples 1-10 were tested under normal conditions, and 5% of the total amount of water was added to the test products to test the water resistance of the products. The products were stored at -5°C for 1 month to test the low temperature stability of the products. The performance measurement results are as follows:

[0140]

[0141] It is concluded from Examples 1-3 and Comparative Examples 1-10 that

[0142] The product of Example 3 of the present invention has excellent combustion value performance under normal conditions, and at the same time, has obvious oxidation corrosion performance effect. The product can achieve coordinated improvement of oxidation corrosion and combustion value, and still has excellent combustion and oxidation corrosion performance under waterproof and low temperature conditions;

[0143] From Comparative Examples 1-10 and Example 3, it can be seen that the present invention does not add the flaky graphene agent based on doping cerium / yttrium and does not add one of the regulating modifiers, and the performance of the product has a significant deterioration trend.

The performance of the products based on no synergist treatment is more obvious. The performance effect of the products based on cerium / yttrium-doped flake graphene agents obtained by the method of the present invention is the most significant.

[0145] When no nano-carbon liquid, hydroxyapatite and urea are added to the regulating modifier, the performance of the product also shows a trend of deterioration. The performance effects of the products of the regulating modifiers obtained by different methods all show a trend of deterioration.

[0146] Since the performance of the product is greatly changed by the modifier, further research is conducted on this:

[0147] The preparation method of the synergist is as follows:

[0148] The carbon nanotubes are first immersed in a sufficient amount of sodium silicate solution and mixed thoroughly, and after the immersion is completed, the solution is filtered and dried;

[0149] 5.5 parts of dried carbon nanotubes and 3.5 parts of lanthanum oxide were added to 8 parts of sodium lignin sulfonate solution, and then 2 parts of nano titanium dioxide and 2.5 parts of silane coupling agent KH550 were added, and the mixture was blended and ball-milled to obtain an efficiency regulator.

[0150] Experimental example 1.

[0151] The only difference from Example 3 is that no dried carbon nanotubes are added in the preparation of the performance modifier.

[0152] Experimental example 2.

[0153] The only difference from Example 3 is that the dried carbon nanotubes are not treated with a sodium silicate solution.

[0154] Experimental Example 3.

[0155] The only difference from Example 3 is that lanthanum oxide is not added in the preparation of the performance modifier.

[0156] Experimental Example 4.

[0157] The only difference from Example 3 is that no nano titanium dioxide is added in the preparation of the performance modifier.

[0158] Experimental Example 5.

[0159] The only difference from Example 3 is that the silane coupling agent KH550 is not added in the preparation of the conditioning agent and the sodium lignin sulfonate solution is replaced by deionized water.

[0160]

[0161] It can be seen from Experimental Examples 1-5 that dry carbon nanotubes were not added in the preparation of the performance-enhancing agent. Among the preparation factors of the performance-enhancing agent, the performance of the product deteriorated significantly. The second was that nano-titanium dioxide and lanthanum oxide were not added. The performance of the product showed a trend of deterioration. The dry carbon nanotubes were not treated with sodium silicate solution, silane coupling agent KH550 was not added, and deionized water was used instead of sodium lignin sulfonate solution. The performance of the product also showed a trend of deterioration. Only the performance-enhancing agent prepared by the specific raw materials of the present invention has the most significant performance effect. The technical effect of the present invention cannot be achieved by replacing other raw materials.

[0162] 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.

[0163] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. 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.
