Pure vinyl ester resin There is an absorption peak of -OH at 3470cm ^-1 . After adding isocyanatopropyltriethoxysilane (IPTS), the absorption peak of -OH shifts to the right and broadens, and a new absorption appears at 3418cm ^-1 Peak, this peak is the absorption peak of -NH, indicating that the hydroxyl group on the side chain of EA reacts with the -NCO group on IPTS, and IPTS is grafted to EA.

It can be seen from Figure 2 that the water droplets are in the form of beads on the surface of the superhydrophobic coating, and the water contact angle is relatively large, which is 153°.

The coatings prepared in Examples 1 to 6 and Comparative Examples 1 to 3 were tested for performance, as follows:

The performance test results are listed in Table 1.

Table 1 Performance test results of the coatings prepared in Examples 1-6 and Comparative Examples 1-3

According to the data in Table 1, comparing Example 1, Example 2 and Example 4, it can be seen that with the increase of silane content, the contact angle of the coating gradually increases, which is because the long chain of silicone is grafted to the main chain of the vinyl resin. After the coating, the low surface energy silicone is easy to migrate to the surface of the coating to reduce its surface energy, thereby improving its hydrophobicity, and when the amount of silane added is within 30%, it will not affect the hardness and adhesion of the coating. ;

Comparing Example 2 and Example 3 (Example 4 or Example 5), it can be seen that with the increase of micron-sized silica content, the contact angle of the coating will increase, which is due to the more micron-sized silica content. , the more obvious the rough structure on the surface of the coating, the more conducive to the hydrophobicity of the coating, but too much micron-sized silica will reduce the hardness of the coating;

As can be seen from Example 1 and Comparative Example 1, the contact angle of the coating without adding micron-scale silica is relatively small, and the hydrophobicity of the coating will be significantly improved after adding micron-scale silica;

As can be seen from Example 1 and Comparative Example 2, due to the small particle size and low density of nano-scale silica, the viscosity of the coating obtained in Comparative Example 2 is relatively large, and it is not easy to coat a film, and the cured coating of the coating film is easy to crack, resulting in coating. The hardness and adhesion of the layer are poor;

It can be seen from Example 1 and Comparative Example 3 that the coating prepared with the modified vinyl resin has stronger hydrophobicity.

The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the principles of the present invention, several improvements and modifications can be made. It should be regarded as the protection scope of the present invention.
