Embodiment 1

[0028] The preparation method of a kind of wind power blade leading edge protective coating provided by the present invention is: by weight, 10 parts of absolute ethanol, 3 parts of triethoxymethylsilane and 10 parts of ethoxyphenyl Add the silicone resin into the reaction kettle and stir evenly, adjust the pH value of the reaction solution to about 6 with acid (acetic acid or acrylic acid), and continue to stir at room temperature for about 10 minutes to obtain the silicone resin prepolymer.

[0029] After mixing 7-8 parts of nano-titanium dioxide, 1-2 parts of nano-cerium oxide, 1 part of acrylic resin and 6 parts of water, put them into a ball mill and grind for about 40 minutes at a speed of 250r / min to obtain functional fillers Dispersions.

[0030] Stir 1 part of silicone resin prepolymer, 1 part of functional filler dispersion and 5-15 parts of polytetrafluoroethylene emulsion (60% solid content) at room temperature for about 15 minutes, then filter with copper mesh to ...

Abstract

The invention discloses a wind turbine blade leading edge protective coating and a preparation method thereof. The preparation method comprises the steps: in parts by weight, mixing 7-8 parts of nanotitanium dioxide, 1-2 parts of nano cerium oxide, 1 part of acrylic resin and 6 parts of water and carrying out ball milling to obtain functional filler dispersion liquid; and uniformly stirring 1 part of the silicon resin prepolymer, 1 part of the functional filler dispersion liquid and 5-15 parts of the polytetrafluoroethylene emulsion to obtain the wind turbine blade leading edge protective coating. The coating disclosed by the invention has the weather resistance of a ceramic coating and the toughness of resin, and is wear-resistant and strong in hydrophobicity. Meanwhile, the preparationmethod of the coating disclosed by the invention is composed of common industrial production processes, the process is simple, large-scale production is easy to realize, and the coating has a wide application prospect in the aspect of wind turbine blade leading edge protection.

Description

technical field [0001] The invention belongs to the technical field of wind power, and in particular relates to a coating which can be used for the front edge protection of wind power blades and a preparation method. Background technique [0002] The blade is the only component of the wind turbine to capture wind energy, and its safe and stable operation is the basis for the wind turbine to obtain high wind energy utilization coefficient and economic benefits. The leading edge of the blade (the position from the blade tip to the 1 / 3 length of the blade root) has been in a high-speed running state for a long time, and placed in the natural environment, affected by factors such as aerodynamic friction, aging, rain erosion, salt spray, sand erosion, and biological erosion. If protection is not carried out, corrosion will generally begin to occur after 0.5 to 2 years of operation. In mild cases, the aerodynamic shape of the blades will be changed, resulting in increased resistan...
