Abstract

The invention discloses a wind turbine blade polypyrrole nanometer coating anti-icing technical method, and belongs to the wind turbine manufacturing technology. A wind turbine blade is coated with apolypyrrole nanometer coating; particularly, the nanoscale polypyrrole powder is subjected to ball milling, after gloss black gloss is produced, the ball-milled polypyrrole powder, polyvinylidene fluoride, N-methylpyrrolidone and absolute ethyl alcohol are mixed according to the mass ratio being 8:1:32:16, the mixed materials are ultrasonically stirred to be uniform to form black sticky liquid, the surface of a wind turbine blade shell is evenly coated with the black sticky liquid, the wind turbine blade is placed into the drying box to be dried for 10h at the temperature of 40 DEG C, and thewind turbine blade coated with the black polypyrrole nanometer hydrophobic coating is obtained. The method is novel, reasonable and easy, the coating is low in self weight, the wind turbine blade is good in anti-icing effect and sealing performance, long in service life and high in accommodative ability of environment.

Description

technical field [0001] The invention belongs to the wind turbine manufacturing technology, and mainly relates to a polypyrrole nano-coating anti-icing technology method for wind turbine blades. Background technique [0002] In recent years, due to massive consumption in industry and daily life, natural energy sources such as coal and oil have been continuously reduced. In order to solve the energy crisis, wind power projects have received extensive attention. In a wind power generation system, wind turbine blades are an important part of obtaining wind energy. However, wind turbine blades exposed to cold climates often experience icing. If the ice that forms on wind turbine blades is not removed in time, serious problems can arise. In order to ensure the maximum reliability of wind turbine blades and reduce the economic loss caused by icing, two main methods to reduce or eliminate icing of wind turbine blades are proposed: (1) Active deicing methods: such as thermal, elect...
