Abstract

The invention discloses an ice inhibiting agent capable of being sprayed on the surface of a wind turbine blade and a preparation method of the ice inhibiting agent. The ice inhibiting agent comprises hyperbranched polyglycerol, an anticoagulant and a thickening agent, wherein the three substances are all added into deionized water. According to the invention, the hyperbranched polyglycidyl has highly branched hydrophilicity, has a large number of terminal functional groups, and has low melting point and solution viscosity; potassium carbonate (sodium acetate, sodium lactate or potassium acetate) is used as an effective component for reducing an ice freezing point; sodium carboxymethyl cellulose is adopted as the thickening agent; and thus, the consistency of the liquid ice inhibiting agent is effectively increased, the ice inhibiting agent is attached to the surface of the wind turbine blade, the freezing point of the surface of the blade is effectively reduced, the dosage of organic matter and inorganic salt (organic salt) is small, the liquid ice inhibiting agent is degradable, secondary pollution to the environment is avoided, and the liquid ice inhibiting agent can be sprayed on the wind turbine blade in a large area and does not corrode a surface coating of the wind turbine blade.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to an anti-icing agent which can be sprayed on the surface of wind power blades and a preparation method thereof. Background technique [0002] Wind turbines are usually located in areas prone to freezing, such as high mountains or frontiers. Because the annual average temperature in these areas is low, and it is common for outdoor temperatures to be below zero, the surface of the blades of wind turbines is prone to freezing. In some cases, it will not only affect the aerodynamic performance of the blades and reduce the power generation efficiency of the unit, but will cause a loss of about 20% to 50% of the power generation in areas with severe icing, and will also affect the service life of the blades, which will bring harm to the operating units and personnel. adverse effects. [0003] Common blade anti-icing / deicing technologies include: thermal deicin...
