Abstract

The invention provides a superhydrophobic acrylic resin paint. The paint comprises a nanoparticle, an acrylic resin, a mixed solvent, and heptadecafluoro trimethoxy ethoxy silane, wherein the ratio of the nanoparticle to the acrylic resin to the mixed solvent to heptadecafluoro trimethoxy ethoxy silane is 100:20-60:20-600:3-10. When the paint is sprayed on the surface of a solid, the contact angle of water drops on the surface is 150-160DEG, and the roll angle of the water drops on the surface is less than 10DEG. The superhydrophobic acrylic resin paint of the invention, which has the advantages of low cost, simple construction technology and small pollution to environment, has a good industrialized application prospect.

Description

Technical field: [0001] The invention describes a superhydrophobic acrylic resin coating suitable for various surfaces. Background technique: [0002] Coatings are widely used in construction, industry, agriculture and other fields. However, the surface of ordinary coatings is poor in water resistance, easy to accumulate dust, and has no self-cleaning performance. The development of coatings with super waterproof performance and self-cleaning property has become an urgent demand of domestic and foreign markets and users. [0003] Inspired by the lotus leaf effect, superhydrophobic materials with surface-water contact angles greater than 150° have attracted widespread interest in recent years. The typical characteristics of super-hydrophobic materials are: when water droplets form shiny spherical water droplets on the surface of super-hydrophobic materials, as long as the surface of the material is slightly tilted or under the action of a breeze, the water droplets will quic...
