InactiveCN106905795ASimple and fast operationUniversalCoatingsMicroballoon preparationMicrosphereMaterials science
The invention discloses a superhydrophobic coating with a raspberry-like structure composite particle and a preparation method thereof. The superhydrophobic composite raspberry particle has a two-level hierarchical structure, and is composed of a polymer nanoparticle with a diameter of 10nm to 1000nm. The spherical core is composed of multiple smaller inorganic nanospheres attached to it. Among them, the organic spherical core refers to the polymer nanosphere with a diameter of 10nm to 1000nm, and the inorganic pellet is formed by the reaction of the following main raw materials on the spherical core according to the mass percentage: organic solvent: 70.02-90.75%; catalyst: 5.18-8.85% %; water: 5.85-8.89%; silicate: 1.12-2.02%; fluorine-containing silane coupling agent: 0.14-1.54%. Because the composite raspberry particles of the invention have a secondary hierarchical structure, the surface roughness can be increased; and the fluorine-containing silane coupling agent can effectively reduce the surface free energy, and finally a superhydrophobic coating can be prepared. The superhydrophobic coating of the present invention can be coated by various methods, including spraying, scraping, and soaking, without affecting its superhydrophobicity.
