Abstract

The present invention provides a wave-absorbing heat-generating coating for melting ice on a wind turbine blade, and a preparation method therefor. By means of coating the surface of a wind turbine blade with the material, an ice layer on the surface of the wind turbine blade is removed by means of the cooperation between same and microwaves. The coating provided in the present invention uses environmentally friendly chemical components, can be sprayed on a large area of a wind turbine blade, has the advantages of a self-cleaning ability, resistance to heat and humidity, freezing resistance, etc., and does not corrode the wind turbine blade. By means of the coating of the present invention cooperating with microwaves for de-icing, microwave energy can be better absorbed and converted into heat energy to rapidly melt ice at an interface, thereby loosening an ice surface and detaching same. The coating has the advantages of strong microwave absorption, a wide frequency band, high wear resistance, strong adhesive force, good thermal stability, etc.
