Abstract

The invention relates to the field of hydrophobic paint, in particular to a semiconductor superhydrophobic paint and a preparation method thereof. The method comprises the steps of: a. firstly shearing and stirring hydrophobic nanoparticles and a semiconductive filler evenly, then adding 70%-80% of an organic solvent and conducting mixing; b. mixing thermoplastic film-forming resin with the remaining organic solvent, and performing shearing and stirring evenly; c. mixing the solution obtained in step a with the solution obtained in step b, then adding a low surface energy substance, a curing agent and an additive; and d. subjecting the solution obtained in step c to ultrasonic treatment for 2-20min, and then conducting stirring for 5min-2h till uniform stirring, thus obtaining the product. The semiconductor superhydrophobic paint adopting the scheme provided by the invention can realize self-repair, has no power consumption, and does not decompose surface organic substances.

Description

technical field [0001] The invention relates to the field of hydrophobic coatings, in particular to a semiconductor super-hydrophobic coating and a preparation method thereof. Background technique [0002] The phenomenon of superhydrophobicity is ubiquitous in nature, such as the skin of beetles in the desert, the surface of lotus leaves, and the surface of rice husk leaves. When the static contact angle between a solid surface and a water droplet reaches 150 degrees and the slip angle is less than 10 degrees, it is called a superhydrophobic surface. The superhydrophobic surface has extremely low surface energy and slip angle, which can quickly remove surface water droplets. Utilizing the low slip angle and high contact angle of the superhydrophobic surface layer can perform functions such as self-cleaning, drag reduction, and antifouling. For example, outdoor antennas coated with super-hydrophobic coatings can prevent snow accumulation; treated ocean-going ships can be an...
