Problems solved by technology

At present, there are various methods for preparing superhydrophobic materials, such as template method, layer-by-layer assembly method, coating curing method, etc. After the nanostructure is destroyed, the material will also lose its super-hydrophobic properties. To endow the material with super-hydrophobic properties again, more complicated processing is required, which is time-consuming and labor-intensive.

Abstract

The invention discloses a super-hydrophobic spraying transparent solution as well as a preparation method and application thereof. The super-hydrophobic spraying transparent solution is prepared from the following components: a hydrophobic finishing agent, a leveling agent, an antioxidant, a dispersant, a dryer and a film-forming agent at the mass ratio of 1 to (0.005-0.5) to (0.002-0.6) to (0.003-0.4) to (0.002-0.3) to (0.005-0.7), and a solvent, wherein the mass ratio of the solvent to the hydrophobic finishing agent is 100 to (0.01-50). The super-hydrophobic spraying transparent solution disclosed by the invention is convenient to spray, rapid in acting speed and stable in properties and is basically suitable for the surface of any known solid at present; the sprayed substrate has excellent super-hydrophobic property and liquid drop impact resisting capability; the super-hydrophobic spraying transparent solution has the advantages of developed preparation process, low production cost and environment-friendly and toxin-free production process and is applicable to large-scale popularization and application.

Description

technical field [0001] The invention belongs to the field of materials, and relates to a superhydrophobic spraying transparent solution, its preparation method and application, in particular to a superhydrophobic spraying transparent solution, which has optical transparency, droplet impact resistance, temperature and pH stability, durability, and repeatability. Sprayable, transparent super-hydrophobic material that can be sprayed on the surface of various materials. Background technique [0002] With the gradual deepening of bionics research, various new materials based on biological characteristics have also been developed and benefit people's daily life. Among them, the current research hot super-hydrophobic material is the simulation of the lotus leaf effect of "out of silt without staining". It is generally considered that a solid surface with a contact angle greater than 150° with water droplets is a superhydrophobic surface. The water droplet is spherical on the surf...
