Abstract

The invention discloses a preparation method of a super-hydrophobic paint, which comprises the following steps: mixing a fluorine-containing polymer emulsion and a polymer emulsion to obtain a mixed liquor, adding organic micronanoparticles, and then diluting by a diluents, uniformly mixing to obtain the super-hydrophobic paint. The preparation method has the advantages of simple process, low processing cost, economic benefit and business application prospect. The invention also discloses the super-hydrophobic paint and a coating prepared by the super-hydrophobic paint. The coating has outstanding waterproofness, the static state contact angle can reach as high as 163 DEG, a scope of roll angle is in 5 DEG, adhesiveness and acid and alkali resistance performance are excellent, solidification temperature is obviously low than that of the fluorine-containing polymer emulsion, the coating is capable of being contacted by hand, when the coating is used in equipment or occasion which is not frequently contact with a friction piece, the coating has waterproof effect, and can overcome restriction of low service life of the material.

Description

technical field [0001] The invention relates to the field of coating preparation, in particular to a preparation method of a superhydrophobic coating and its product and application. Background technique [0002] Superhydrophobicity refers to the phenomenon that the static contact angle of water on the surface of an object is greater than 150° and the rolling angle is within 10°. The macroscopic manifestation is that water cannot stay on the surface of an object, and it is easy to form water droplets and roll off. Due to the applicability of the superhydrophobic phenomenon in the field of self-cleaning and antifouling, superhydrophobic materials have attracted extensive attention. It has been found that some parts of various organisms in nature, such as lotus leaves, geckos, and water striders, all exhibit this characteristic, the most prominent of which is the "lotus leaf effect". They provide material templates for systematically studying the structure and principle of su...
