[0002] Marine coatings are coatings used on various parts of ships, which have protective and decorative functions on the surface of ships.

[0003] To improve wear resistance, existing marine coatings typically incorporate high-hardness particles. However, large amounts of fine particles can make the coating surface rough, generating significant friction when subjected to external forces, resulting in less-than-ideal wear resistance. To address this issue, the present invention provides a high-performance marine coating based on basalt fiber flakes and a method for preparing the same. Summary of the Invention

After the ship coating is completed, the basalt flakes bear the main friction stress, and the ox horn powder utilizes its plastic deformation ability to absorb impact energy, thereby establishing a rigid and flexible complementary structure, thereby achieving a synergistic improvement in the wear resistance and adhesion of the ship coating.

[0020] 3. In the present invention, during the preparation process of the filler, the internal pores of the horn powder can be eliminated by pressing, its surface roughness can be reduced, and the surface stress concentration points after coating are reduced, thereby improving the wear resistance of the coating.

[0062] Comparative Example 3: The difference between this comparative example and Example 1 is that in this comparative example, an equal amount of nano-silicon dioxide is used to replace the filler.

[0063] Comparative Example 4: This comparative example is different from Example 1 in that: this comparative example does not contain filler.

[0064] Performance test: The marine coatings prepared in Example 1, Example 2, Example 3, Comparative Example 1, Comparative Example 2, Comparative Example 3 and Comparative Example 4 were subjected to performance tests, and the test data obtained are recorded in the following table:

[0065] Test items Wear mass loss (mg) Adhesion grade Example 1 5.1 1 Example 2 4.9 0 Example 3 5.4 1 Comparative Example 1 8.9 2 Comparative Example 2 9.7 2 Comparative Example 3 11.4 3 Comparative Example 4 12.6 3

[0066] In the performance test, the test method in GB / T1768-2006 was used to test the wear mass loss of the marine coatings prepared in Example 1, Example 2, Example 3, Comparative Example 1, Comparative Example 2, Comparative Example 3 and Comparative Example 4;

[0067] The test method in GB / T9286-2021 was used to test the adhesion grade of the marine coatings prepared in Example 1, Example 2, Example 3, Comparative Example 1, Comparative Example 2, Comparative Example 3 and Comparative Example 4.

[0068] It can be seen that the wear resistance and adhesion performance of the ship coatings prepared in Comparative Examples 1, 2, 3, and 4 are lower than those in Examples 1, 2, and 3; this shows that: in the preparation of the ship coating, by adding the filler therein, after the ox horn powder is treated, the amino groups of the ox horn powder collagen undergo a free radical grafting reaction to form polyvinyl ester side chains, which plays a role in increasing the surface polar groups, thereby being able to form hydrogen bonds with the hydroxyl groups of the epoxy resin, and being able to cooperate with methyl methacrylate to form a coating layer to form a three-dimensional network structure, effectively improving the toughness of the coating, and thus improving the wear resistance of the ship coating;

[0069] By combining basalt fiber flakes with ox horn powder in the filler system, the basalt fiber flakes, with their flaky structure, can be arranged in the coating to form a dense barrier, increasing hardness while also blocking the penetration of corrosive media. After the ship coating is applied, the basalt flakes bear the main friction stress, while the ox horn powder absorbs impact energy through its plastic deformation ability. This creates a complementary rigidity and flexibility structure, achieving a synergistic improvement in the wear resistance and adhesion of the ship coating.

[0070] During the preparation process of the filler, the internal pores of the horn powder can be eliminated through pressing, its surface roughness can be reduced, and the surface stress concentration points after coating can be reduced, thereby improving the wear resistance of the coating.

[0071] Comparing and analyzing the relevant data in the table shows that the marine coating prepared by the present invention not only has good wear resistance but also excellent adhesion. This shows that the high-performance marine coating based on basalt fiber flakes provided by the present invention has a broader market prospect and is more suitable for promotion.
