Functional filler, water-based wind power blade anti-icing coating and preparation method of water-based wind power blade anti-icing coating

The invention relates to the technical field of coatings, and provides a functional filler, a water-based wind power blade anti-icing coating and a preparation method of the water-based wind power blade anti-icing coating. Wherein one functional filler is formed by compounding tetragonal pyramid type zinc oxide modified by a silane coupling agent, graphene oxide and citric anhydride. According to the water-based wind power blade anti-icing coating provided by the invention, the functional filler formed by compounding the tetragonal pyramid-shaped zinc oxide modified by the silane coupling agent, the graphene oxide and the citric anhydride is adopted, so that the water-based wind power blade anti-icing coating has an excellent surface hydrophobic effect, and has excellent corrosion resistance while effectively preventing adhesion of an ice layer; meanwhile, the preparation method is simple, the solvent content is low, and the emission requirement is met. 本发明涉及涂料技术领域，提供一种功能填料、水性风电叶片防覆冰涂料及其制备方法。其中，一种功能填料，由经硅烷偶联剂
