Description
Technical Field
The invention belongs to the technical field of anti-icing materials, and particularly relates to a composite functional anti-icing coating on the surface of a fan blade and a preparation method thereof.
Background
In recent years, due to the proposal of a carbon neutralization concept, the utilization of novel clean energy sources becomes hot, and wind energy is taken as clean renewable energy sources which store huge energy, so that wind power generation becomes one of main power generation modes in China.
Since the wind power plant is generally located at a higher altitude area or at an open sea area, blade icing is unavoidable especially when running in winter. The icing on the surface of the fan blade can cause the increase of critical part limit load and fatigue load, and the structural safety is damaged, meanwhile, the geometric shape of the blade is changed to break the pneumatic performance of the blade, the wind energy utilization rate is reduced, the power generation efficiency is seriously affected, and particularly in the areas with high occurrence of rain, snow and frost weather, huge power loss can be caused.
Aiming at the problem of icing of the existing blade, the existing deicing modes mainly comprise an active deicing mode and a passive deicing mode. The active deicing mode comprises mechanical deicing, thermal deicing, ultrasonic deicing and the like, but has the problems of high energy consumption, great popularization difficulty and the like. The passive deicing modes comprise coating anti-icing, solution anti-icing and the like, wherein the coating anti-icing adopts super-hydrophobic materials, and solution anti-icing research is mainly focused on lowering the freezing point temperature of the surface of the fan blade, so that the blade is not easy to be coated with ice. However, the hydrophobicity of the coating is not durable enough, and frequent smearing is time-consuming and labor-consuming; the anti-icing duration of the anti-icing solution is short, and the anti-icing effect becomes lower along with the decrease of the ambient temperature, and the duration is short.
Therefore, there is still a need to develop an anti-icing strategy that is better in performance, stable and efficient to solve the above-mentioned prior art problems.
