Abstract

The invention discloses a method for preparing a superhydrophobic wire. The method comprises the steps of winding a single wire around a paying-off roller, sequentially continuously performing surface pretreatment, sand blasting, chemical etching treatment, surface finish treatment and wire winding on the single wire through the traction effect, and obtaining the finished wire. In the method for preparing the superhydrophobic wire, the surface of the wire is subject to sand blasting so as to form a micropore structure, a nano-structure excellent in structure is formed by collaboration of chemical etching and a surfactant, and the excellent superhydrophobic performance of the superhydrophobic wire is guaranteed.

Description

technical field [0001] The invention relates to a method for preparing a wire, in particular to a method for preparing a superhydrophobic wire. Background technique [0002] Superhydrophobic surface properties on metal substrates have broad application prospects. It is generally believed that the combination of micron and nanoscale composite rough structures and low surface free energy are two necessary conditions for superhydrophobic surfaces. In the prior art, there are two methods for forming the rough structure on the surface of metal aluminum: chemical method and electrochemical method. The chemical method usually uses acid or alkali to corrode metal aluminum to obtain the rough structure. The chemical corrosion method is simple and can quickly obtain micron The electrochemical method is generally an anodic oxidation method, which is easy to form a uniform nano-scale rough structure, but the processing time is long, which is not conducive to large-scale production. The...
