Problems solved by technology

For example, patent CN101108947A uses inorganic conductive filler as the coating of conductive filler, but the compatibility of inorganic filler and resin becomes worse, so that the mechanical properties of the paint film decline; patent CN102070960A uses conductive polymer as the coating of conductive filler, but the cost is higher
Patent CN1704191A uses metal powder as the conductive filler of coating, but its corrosion resistance is not good

Abstract

The invention relates to electric-conductive super-hydrophobic paint. The electric-conductive super-hydrophobic paint is obtained by mixing a component A and a component B according to a weight ratioof 10:(1-5), wherein the component A comprises the following preparation raw materials: epoxy resin E44, polyurethane emulsion, polytetrafluoroethylene emulsion, sulfonated graphene oxide, cyclodextrin modified polyester coated nano yttrium oxide, a cyclodextrin modified polyester coated carbon nano tube and a solvent C; and the component B comprises the following preparation raw materials: polyether amine grafted with hyaluronic acid, 1-methyl-4-aminoimidazole, hexamethylenediamine and a solvent D. The invention further relates to a preparation method for the electric-conductive super-hydrophobic paint. The electric-conductive super-hydrophobic paint is good in cleaning property, anti-pollution and good in conductivity, and has good market prospect.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a conductive superhydrophobic coating and a preparation method thereof. Background technique [0002] With the development of the defense industry, daily necessities, and medical equipment, the demand for super-hydrophobic conductive coatings is increasing. Currently, there have been reports on superhydrophobic conductive coatings. For example, patent CN101108947A uses inorganic conductive filler as the coating of conductive filler, but the compatibility of inorganic filler and resin becomes poor, so that the mechanical properties of the paint film decline; patent CN102070960A uses conductive polymer as the coating of conductive filler, but the cost is higher. Patent CN1704191A adopts metal powder as the conductive filler of coating, but its corrosion resistance is not good. [0003] For this reason, process development is required to improve formulations and obtain new coatin...
