Embodiment 1

[0033] A kind of superhydrophobic coating, comprises following component according to mass parts:

[0034]

[0035] In this embodiment, the curing agent is prepared by fluorinating diethylenetriamine and heptafluorobutyric acid, and the mass ratio of diethylenetriamine and heptafluorobutyric acid is 1:2. The preparation method of this curing agent comprises the following steps:

[0036] (1) Dissolve 10 parts of diethylenetriamine in 100 parts of deionized water, and stir on a magnetic stirrer plate at a rotation speed of 125 rpm to obtain a diethylenetriamine solution.

[0037] (2) Dissolve 20 parts of heptafluorobutyric acid (≥99.5% (GC)) in 100 parts of deionized water, and add the obtained heptafluorobutyric acid solution dropwise to the diethylenetriamine prepared in step (1) The fluorination reaction is carried out in the solution, and after all the heptafluorobutyric acid solution is added dropwise, the resulting mixture is heated to 100° C. to evaporate all the wate...

Embodiment 2

[0043] A preparation method for a superhydrophobic coating, comprising the steps of: coating the superhydrophobic coating in Example 1 on a glass substrate, drying in vacuum for 5h at a temperature of 80° C., immersing in a stearic acid solution (the stearic acid Acid solution is prepared by dissolving stearic acid in acetone, wherein the mass fraction of stearic acid in the stearic acid solution is 5%), and dried to obtain super-hydrophobic coating.

[0044] The superhydrophobic coating prepared in this example has a thickness of 0.1 mm to 0.5 mm.

[0045] figure 1 It is a physical schematic diagram of the superhydrophobic coating prepared in Example 6 of the present invention. Depend on figure 1 It can be seen that the contact angle of the superhydrophobic coating made in Example 2 of the present invention is 152.8 ° and the rolling angle is 3 °, showing excellent superhydrophobic performance, when the superhydrophobic coating is attached on the wind turbine blade, it can ...

Abstract

The invention discloses super-hydrophobic coating material and a preparation method thereof, and discloses a super-hydrophobic coating and a preparation method thereof. The super-hydrophobic coating material is prepared from the following raw material components in parts by mass: 10-30 parts of a curing agent, 10-30 parts of epoxy resin, 80-120 parts of polytetrafluoroethylene powder, 0-10 parts of fluoropolymer, 10-30 parts of zinc oxide and 40-80 parts of a solvent, wherein the curing agent is prepared by carrying out a fluorination reaction on diethylenetriamine and heptafluorobutyric acidin a mass ratio of 1:2. The super-hydrophobic coating is prepared from the super-hydrophobic coating material. The super-hydrophobic coating material has the advantages of excellent super-hydrophobicperformance, strong weather resistance and the like, can be used for preparing the super-hydrophobic coating, and has relatively high use value and a relatively good application prospect. The preparation method of the super-hydrophobic coating has the advantages of being simple in process, convenient to operate and the like, can prepare the super-hydrophobic coating with excellent self-hydrophobicanti-icing performance on a large scale, and facilitates industrial application.

Description

technical field [0001] The invention belongs to the technical field of super-hydrophobic coatings, and relates to a super-hydrophobic coating and a preparation method thereof, and a super-hydrophobic coating and a preparation method thereof. Background technique [0002] Wind energy is a clean and renewable energy source. In recent years, with the emphasis on environmental issues in various countries, wind power generation has become one of the most potential new energy generation methods. Most of the wind farms in southern my country are built in mountainous areas with high altitudes. These areas usually have high humidity, and the temperature in winter is below zero. There is a phenomenon of ice on the surface of the blades. Capturing and transmitting wind energy, if the blades freeze, it will change the aerodynamic characteristics of the blades, affecting the performance and power generation of the entire wind turbine. There are two main solutions to the icing problem of ...
