Problems solved by technology

Although there are related reports on superhydrophobic coatings in the field of anti-icing of wind turbine blades, because superhydrophobic coatings need to contact some putty in the air, the superhydrophobic properties are quickly lost, so superhydrophobic coatings cannot be used on a large scale for a long time , some previous reports on anti-icing of superhydrophobic coatings for wind turbine blades are only in the theoretical and laboratory stages, and cannot be applied on a large scale in the field.

Abstract

The invention discloses an energy-absorbing super-amphiphobic anti-icing coating for a fan blade and a preparation method thereof. The coating is prepared from the following raw materials in parts byweight: 8-15 parts of super-amphiphobic modified carbon nanotubes, 2-5 parts of porous filler powder, 45-70 parts of modified resin, 2-4 parts of a dispersing agent, 1-2 parts of an antifoaming agent,2-3 parts of a leveling agent and 15-27 parts of a solvent. The novel energy-absorbing super-hydrophobic anti-icing material is designed mainly based on the lotus leaf super-hydrophobic bionic principle, and the super-amphiphobic function (super-hydrophobic and super-oleophobic) of the material is achieved by adopting low-surface-energy organic matter to construct a rough surface structure. A coating formed by the energy-absorbing super-amphiphobic anti-icing coating for the fan blade provided by the invention has strong adhesive force, high weather resistance and strong anti-icing capability, has an obvious delayed icing effect during snowing, greatly reduces the icing amount, and meanwhile, has an energy-absorbing characteristic, so that the coating is extremely easy to deice even at anextremely low temperature (below zero DEG C), and therefore, the fan blade using the coating provided by the invention has an anti-icing function.

Description

technical field [0001] The invention relates to the field of fan blade anti-icing technology, in particular to an energy-absorbing superamphiphobic anti-icing coating for fan blades and a preparation method thereof. Background technique [0002] Wind energy is a clean and renewable energy source. Wind power generation is not only a supplement to conventional electricity in my country, but also a trend in future electricity development. However, wind farms are often built on high mountains with sufficient wind energy and low temperature, and the problem of icing on the surface of wind turbine blades has become increasingly prominent. On the one hand, icing on the surface of the blades will lead to overloading of the blades and uneven distribution of ice loads on the blades, resulting in low efficiency of the wind turbine. On the other hand, during the rotation of the blades, large ice sheets fall off, which can easily cause operational accidents. [0003] Traditional deicin...
