Inorganic substance super-hydrophobic paint and application thereof
The invention relates to inorganic substance super-hydrophobic paint and application thereof. The paint is prepared in the following method: silica sol is injected into a reactor with a nano microsphere template under a negative pressure condition, the template is immersed in the silica sol for 2h, then the reactor is sealed and stored in a thermostat, the silica sol and the template react at the temperature of 60 DEG C for 12h, the template is removed by virtue of heating or water immersion, a solid blocked micro-nano composite polygon is obtained, and after the blocked micro-nano composite polygon is dried, the blocked micro-nano composite polygon is ground into powder; the powder is poured into another reactor, dispersion liquid acetone is mixed with the powder, a low-surface-energy silane coupling agent is used for modifying the powder at a temperature of 25 to 50 DEG C, the powder reacts for 10h to 15h, the micro-nano composite polygon powder accounts for 0.5 to 20 percent of the mass of the paint, and the super-hydrophobic paint is prepared. The inorganic substance super-hydrophobic paint can be smeared on the surfaces of various conventional materials, the preparation method of the paint is simple, and the obtained super-hydrophobic surface is excellent in stability.
