Method for preparing noise-reduction anti-icing wind turbine blade material

Abstract

The invention belongs to the technical field of production of composite material blades for wind power generation, and concretely relates to a method for preparing a noise-reduction anti-icing wind turbine blade material. The method comprises the following steps: dissolving a polymer mixture in N,N-dimethylformamide to obtain a blend spinning dope, spinning the blend spinning dope to obtain pre-oxidized fibers, sintering the pre-oxidized fibers to obtain a carbon fiber preform, winding the pre-oxidized fibers around the surface of anodized aluminized carbon fibers, and coating the outer surface of the pre-oxidized fibers with a curing solution to obtain the noise-reduction anti-icing wind turbine blade material. The blend spinning dope is prepared from two polymers, and sound energy is converted into heat energy when the wind turbine blade absorbs sounds and vibrates, so the sound absorption and noise reduction performances of the wind turbine blade are improved; paraffin oil is heatedand micro-melted when the wind turbine blade is rubbed at a high speed in order to form an oil film, so water erosion is prevented; and tourmaline powder prevents metals from being oxidized, losing electrons and being corroded, and a chlorine salt can improve the freeze-thaw resistance of the wind turbine blade, so the material has broad application prospects.
