Problems solved by technology

[0004] However, the surface structure of superhydrophobic materials prepared by most current methods is unstable. When encountering slight external force friction, its surface structure is easily destroyed, resulting in a decrease in the hydrophobicity of the surface of the material, or even loss of hydrophobicity.

Abstract

The invention discloses a preparation method of a super-hydrophobic material with good mechanical stability. The super-hydrophobic material resistant to certain mechanical friction can be prepared byusing the method. The preparation method comprises the following steps that firstly, resin A, resin B and resin C are dissolved in a mixed solution A containing a solution A and a solution B, and stirred at room temperature to obtain a raw material A; subsequently, hydrophobic silica particles, an auxiliary agent A and an auxiliary agent B are dissolved in the solution B and sonicated to obtain araw material B; and then the raw material A is roll-coated on a metal enclosure plate, after the surface is slightly dry, the raw material B is roll-coated on the surface coated with the raw materialA of the metal enclosure plate, then the plate is dried in a blast drying box, and after cooling, the super-hydrophobic material with good mechanical stability is obtained. Compared with the prior art, the super-hydrophobic material prepared by the preparation method has super-hydrophobic properties, and has good mechanical stability; and a preparation process is simple, and large-scale industrialproduction is hopefully achieved.

Description

technical field [0001] The invention relates to the technical field of hydrophobic materials, in particular to a method for preparing a superhydrophobic material with good mechanical stability. Background technique [0002] Superhydrophobic materials refer to a class of special materials whose surface contact angle with water is greater than 150° and rolling angle is less than 10°. And industry has a wide range of applications, such as self-cleaning, oil-water separation, anti-corrosion, anti-fouling, etc. [0003] Generally, the construction of superhydrophobic surfaces in materials can be achieved in the following two ways: one is to modify the rough surface with low surface energy substances such as organosilane or fluororesin, and the other is to construct a certain roughness on the hydrophobic surface. At present, there have been many reports on the preparation of superhydrophobic materials. For example, Chen et al. prepared a water-soluble inorganic-organic composite ...
