Coating with long-acting durable super-hydrophobic function

Abstract

The invention relates to a surface hydrophobic agent, in particular to a coating with a long-acting durable super-hydrophobic function. An effective component of the coating with the long-acting durable super-hydrophobic function is a multi-functional group fluorine-containing furan derivative. The structure of the coating is as shown in the specification. The multi-functional group fluorine-containing furan derivative, a pH (potential of hydrogen) value buffer regulator and an auxiliary are mixed and dissolved in solvents according to an appropriate proportion to obtain the stable hydrophobiccoating. The contact angle of the coating can reach 150 degrees or more, and the coating is good in hydrophobic effect, strong in adhesive force and particularly suitable for automotive glass and automotive paint and has super-hydrophobic performance.

Description

technical field [0001] The invention relates to a surface hydrophobic agent, in particular to a coating with a long-lasting and durable superhydrophobic function. Background technique [0002] In nature, lotus leaves, butterfly wings, petals, etc. can be drip-free because the contact angle between water droplets and objects is >150°, forming a super-hydrophobic phenomenon. The core essence is extremely low surface energy and rough micro-nano The structure makes it difficult for water droplets to spread. Although people have been able to prepare a wide variety of superhydrophobic coatings, however, superhydrophobic materials have not been widely promoted at present, which is mainly limited by two reasons: poor adhesion to the substrate and opacity. Common superhydrophobic materials are generally composed of low surface energy materials, such as: fluorine-containing hydrocarbons, long-chain alkanes, etc., which can achieve certain hydrophobic properties; further combined w...

Problems solved by technology

However, due to the need for low surface energy, such fluorine-containing hydrocarbons and long-chain alkanes cannot contain strong polar carboxyl groups, hydroxyl groups, etc., making the material adhesion low

At the same time, the light scattering effect of nanomaterials such as titanium dioxide, aluminum oxide, and silicon dioxide causes superhydrophobic materials to be optically opaque, which affects the large-scale application o
