Description
Technical Field
The application belongs to the technical field of coatings, and particularly relates to an anti-icing nano-coating, a preparation method and application thereof.
Background
In recent years, the wind power installation scale is continuously enlarged, and the power generation duty ratio is greatly improved. The method has the advantages that in most areas of China, the freezing weather in winter is more, the standby withdrawal phenomenon of the wind turbine generator is increasingly remarkable due to the influence of ice coating, and the method has great influence on the safe dispatching operation of the power grid.
When a large amount of ice is deposited on the surface of the fan blade, the unbalanced load of the unit is increased due to different ice loads on each blade, so that the service life of parts of the fan is reduced, and the unit is greatly damaged; the original aerodynamic shape of the blade is changed due to different ice thickness, so that the wind energy utilization coefficient of the wind turbine generator is reduced, the power generation is reduced, and the wind turbine generator can not be started normally when serious; after icing, if the fan continues to operate, the thrown ice fragments or dropped ice cubes may injure the fan itself and people or objects in the vicinity thereof.
The adhesion of ice to the coated surface is affected by several factors:
1. hydrophobicity. The surface of the coating has good hydrophobicity, can reduce the wetting of water to the surface, and greatly reduces the ice coating quantity at the temperature close to 0 ℃. It has also been found that the icephobic surface must be hydrophobic, but not the higher the contact angle of the substrate surface with water, the more hydrophobic the ice adhesion is.
2. Temperature. The water mainly forms rime at the temperature of-6~0 ℃, the whole ice is compact, and the adhesive force to the surface of the base material is good; when the temperature of water is lower than-10 ℃, the water is fast in crystallization speed, so that loose white frost with appearance is formed, and the adhesive force to a base material is low.
3. Roughness. The roughness of the coating surface has a very great influence on the adhesion of ice, for example, the adhesion of ice to a general stainless steel surface is as high as 1.65MPa, but the adhesion of ice to polished stainless steel is only 0.07MPa.
4. Lubricity. The coating surface has good self-lubricating property, and can also greatly reduce the adhesive force of ice.
Disclosure of Invention
