Abstract

The underwater target shell has clear technical requirements for the performance of the superhydrophobic microstructure surface coating which has great influences on the navigation resistance of the underwater target. Polyurethane hydrophobic resin and fluorine modified SiO2 particle filler were synthesized according to the synthetic principle of superhydrophobic coating. Three kinds of superhydrophobic microstructure surface coatings including those based on polyurethane hydrophobic resin, silicon - containing resin and fluorine - containing resin were prepared, and the main components and preparation process of each coating were confirmed. Furthermore, the performance of the three superhydrophobic coatings was tested and evaluated, and their performance indicators were compared and analyzed, such as the thickness, hardness, adhesion, static and dynamic hydrophobic angles, surface microstructure, wear resistance, seawater immersion resistance, salt spray resistance and thermal stability. Results showed that the F660 + 8%SiO2 silicone - containing superhydrophobic coating possessed the best comprehensive performance. This would provide a basis for further resistance test of underwater target shell with superhydrophobic microstructure surface coating.

Key words： underwater target shell; superhydrophobic; microstructure surface coating; hydrophobic angle; silicon - containing resin
