Problems solved by technology

First, the surface of the blades will freeze at low temperatures, which will affect power generation
When microwave deicing is used, because the traditional blade coating does not have obvious microwave absorption function, the microwave utilization rate is low and the energy consumption of deicing is high; second, the blade will generate reflection signals to normal civilian and military microwave radars, which will affect the radar. information security

Abstract

The invention relates to microwave-absorbing wind power blade coating as well as a preparation method and application thereof. The microwave-absorbing wind power blade coating comprises the following components in parts by weight: 70-99.9 parts of traditional blade coating and 0.1-30 parts of a carbon series microwave absorbing material. The preparation method of the microwave-absorbing wind power blade coating comprises the following steps: uniformly mixing 70-99.9 parts of the traditional blade coating and 0.1-30 parts of a carbon series microwave absorbing material; coating the obtained mixture onto a blade by adopting the traditional coating method. Compared with the prior art, the microwave absorbing wind power blade coating has anti-icing and deicing effects and can effectively reduce radar reflection.

Description

technical field [0001] The invention relates to a coating, in particular to a microwave-absorbing wind blade coating and a preparation method and application thereof. Background technique [0002] Wind power is a new type of clean and renewable energy, which accounts for an increasing proportion of the entire energy supply, and major countries in the world are constantly increasing their investment in the field of wind power. Wind turbines are usually divided into three parts: wind blades (hereinafter referred to as blades), towers and hosts, among which blade coating is one of the necessary components of the blades. Traditional blade coatings mainly provide anti-ultraviolet, anti-rain erosion and anti-sand erosion functions. There are also some blade coatings that have added low surface energy special effects in order to reduce the icing on the blade surface. But this low surface energy effect lasts for a very short time, usually only between a few months and a year. Thi...
