Problems solved by technology

The blades are in a high-humidity and low-temperature environment, and they are easy to freeze, which changes the surface curve and reduces the conversion efficiency of wind energy. When the ice is severe, the fan cannot work and affects production.

Embodiment Construction

[0012] The present invention will be further described below according to the embodiments.

[0013] The embodiment adopts xylene as diluent, dibutyl ester as modifying agent, and ethylenediamine as curing agent, and its optimum proportioning ratio is:

[0014] Epoxy 35%

[0015] Graphite powder 35%

[0016] Thinner 15%

[0017] Modifier 7%

[0018] Curing agent 8%

[0019] The process is as follows: graphite powder is ball milled to reach more than 200 meshes, mixed with epoxy resin, added modifier and diluent and stirred evenly, then added curing agent, stirred evenly, and finally painted on the surface of the paddle and cured. .

Abstract

An antifreezing paint for the blades of wind-driven electric generator is prepared from epoxy resin, graphite powder, diluent, modifier and solidifying agent through proportionally mixing. Its advantages are high adhesion and high hydrophobicity.

Description

Technical field [0001] The invention relates to an organic surface coating, especially an anti-icing coating. Background technique [0002] Wind turbines are installed in the wild, especially in some islands and high mountain areas, where the temperature is cold and the humidity is high in winter. The blades are in a high-humidity and low-temperature environment, and they are prone to icing, which changes the surface curve and reduces the conversion efficiency of wind energy. When the icing is severe, the fan cannot work and affects production. Contents of the invention [0003] The purpose of the present invention is to provide a surface paint that is painted on the surface of fan blades to prevent them from freezing. [0004] The scheme of the present invention is: utilizing the non-wetting properties of graphite to water, taking epoxy resin as the base material, adding graphite powder, diluent, modifier, and curing agent, and brushing on the surface of the blade, so th...
