Anti-static and sand erosion-resistant coating material for wind turbines and its preparation method

Abstract

Disclosed is an anti-static and sand erosion-resistant coating material based on in-situ reinforcement modification of cyclodextrin modified carbon nanotubes and its preparation method. It uses specific diisocyanates for surface pretreatment of hydroxylated carbon nanotubes, and then grafts cyclodextrin onto the surface of the pretreated hydroxylated carbon nanotubes to obtain cyclodextrin modified carbon nanotubes. Subsequently, cyclodextrin modified carbon nanotubes are introduced into the synthesis process of polyurethane resin, resulting in a polyurethane resin. It further uses the polyurethane resin as component A and combines it with a curing agent to obtain an anti-static and sand erosion-resistant coating material. The anti-static and sand erosion-resistant polyurethane coating based on in-situ reinforcement modification of cyclodextrin modified carbon nanotubes has high strength, high elasticity, excellent wear resistance, high adhesion, aging resistance, and excellent anti-static function, and can meet the needs of sand erosion-resistant protection for wind turbine blades.
