Abstract

The invention discloses a coating for wind power generation blades. The coating comprises the following components according to mass percents: 20-35% of polyvinyl butyral, 10-20% of hydroxylated acrylic resin, 30-35% of ethoxy end capped dimethyl polysiloxane, 8-10% of alcohol, 8-10% of n-butyl alcohol, 5-6% of A12O3 and 0.5-2% of SiO. The coating for the wind power generation blades provided by the invention has the advantages of excellent adhesive force, weather resistance, flexibility, abrasion resistance, low temperature stability, surface non-freezing performance and curing speed.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to a coating used for wind power generation blades. Background technique [0002] Wind energy is an inexhaustible resource in nature, so wind power has become an important alternative energy source and is developing rapidly. Wind power generating units are generally located in coastal and desert areas, facing high-intensity ultraviolet radiation and wind and sand erosion, etc. The harsh environment they often face puts forward stricter requirements for coatings for wind power blades. Specifically, the adhesion, weather resistance, flexibility, wear resistance, low temperature stability, non-icing performance of the surface layer and curing speed of the coating are required to be outstanding. A large number of studies have been carried out by scientific and technical personnel for the above requirements, but most of them only meet one or part of the above requirements, such as CN1016...
