[0048] In some specific embodiments of the present invention, the coating preparation method of antistatic hydrophilic coating comprises the steps of: mixing carbon nanotubes with an organic solvent to obtain a carbon nanotube dispersion, and then mixing them with epoxy acrylate, polyurethane acrylate , photoinitiator, hydrophilic additive, and auxiliary agent are mixed to obtain an antistatic hydrophilic coating. In some specific examples, the carbon nanotube concentration of the carbon nanotube dispersion is 10 mg / mL-30 mg / mL, such as 10 mg / mL, 15 mg / mL, 20 mg / mL, 25 mg / mL or 30 mg / mL; the organic solvent includes At least one of methanol, ethanol, acetone, ethyl acetate; the mixing method is ball mill dispersion. When the antistatic hydrophilic coating is used, the organic solvent should be removed first, and then used for coating; the method of removing the organic solvent can be heated and evaporated, such as evaporation at 80 ° C to 85 ° C. The coating preparation and a...

[0095] The material preparation method for the wind wheel of this example includes the following steps: drying the AS resin at 80° C. for 2 to 4 hours to remove the adsorbed moisture; mixing 87wt% of AS resin, 13wt% of glass fiber, and accounting for AS resin and glass fiber The mass sum of 0.05wt% graphite powder with a particle size of 100nm is mixed, heated to 200°C-270°C; the mold temperature is controlled at 40°C-60°C, and the heated mixture is injected at an injection pressure of 500bar-1300bar. After the mold is completely filled, it is cooled; after it is completely cooled, it is demolded to obtain the material for the wind wheel.
[0096] The material preparation method for the air duct in this example includes the following steps: dry the ABS resin at 80°C to 85°C for 2 to 4 hours to remove the adsorbed moisture; heat the ABS resin to 220°C to 260°C; control the mold temperature to 60°C ~65°C, inject the heated material at an injection pressure of 500bar~800bar, comp...
