Abstract

The invention discloses a coating solution for improving the water drop angle and the surface smoothness of a protection film, wherein the coating solution comprises, by weight, 90-100 parts of dimethyl silicon oil A with a polymerization degree of 80-100, 15-17 parts of dimethyl silicon oil A with a polymerization degree of 120-150, and 0.005-0.01 part of an alcohol dye solution, and has a viscosity of less than 200 cst. According to the present invention, with the application of the coating solution on the surfaces of optical display screens, the light refraction is uniform, the display is clear, and the use of the display device is not affected; with the application of the coating solution on the interfaces of protection films, the water drop contact angle of the interface is significantly improved, such that the hydrophobicity is substantially improved, the applied surface has high antifouling property, the surface friction coefficient is effectively reduced, the surface smoothnessis improved, and the user experience performance is good; and the coating solution has advantages of high stability, no volatile, convenient use and convenient operation. The invention further provides a preparation method of the coating solution.

Description

technical field [0001] The invention relates to the technical field of antifouling coatings, in particular to a coating solution for improving the water drop angle and surface smoothness of a protective film and a preparation method thereof. Background technique [0002] For transparent optical materials such as glass and plastic compounded on the display, its anti-fouling ability is an important consideration index. The anti-fouling ability of such materials is usually measured by testing the smoothness of the surface and the water drop angle. The sources of contamination of such materials mainly include moisture, dust, oil, and fingerprints. At present, such optical materials are usually prepared into hydrophobic surfaces to play the role of waterproof and antifouling. However, the process of preparing a hydrophobic surface is relatively complicated, the cost is high, and the durability of the prepared hydrophobic surface is poor. [0003] Coating technology, especially...
