Problems solved by technology

[0003] Most of the fan blades are made of epoxy fiberglass, and there are also unsaturated polyester resin composite materials, which have the advantages of light weight, good mechanical properties, and low cost, but there are still some shortcomings: such as poor weather resistance, poor wear resistance, etc.
[0006] Chinese patent 200710099350.8 discloses a highly hydrophobic anti-icing and anti-icing coating. The characteristics of various anti-icing coatings are compared, and the effect of anti-icing and frosting is achieved by constructing a highly hydrophobic surface, but it does not The weather resistance and wear resistance of the coating are studied. In addition, the coating needs to be cured by heating (heat curing at 100°C for 7 hours), which is not suitable for the coating of wind turbine blades

Abstract

The invention discloses a super weather-resisting, wear-resisting and anti-icing wind-powered blade coating and a preparation method thereof. A component A comprises the following compositions in percentage by mass: 27-44% of fluorocarbon resin, 10-25% of polyester resins, 0.5-2% of a silane coupling agent, 0.5-2% of a wetting dispersant, 0.5-2% of a thixotropic agent, 1-5% of nano titanium dioxide, 3-6% of nano alumina, 12-18% of a pigment, 5-10% of packing, 3-6% of extinction powder, 0.1-1% of an ultraviolet light absorber, 0.1-0.8% of a flatting agent, 0.01-0.4% of a defoaming agent and 5-10% of a diluent; and the component A and aliphatic isocyanate are proportioned according to a formula that -NCO / -OH = 1.05-1.2. The coating disclosed by the invention is outstanding in weather resistance and wear resistance, and can carry out long-acting protection on wind-powered blades and save the maintenance cost; the water contact angle is greater than or equal to 150 degrees, and the ice cover can be reduced by more than 50%; and the surface dry is implemented in 0.5 h, the hard dry is implemented in 24 h, and the coating can be subjected to brush coating, roll coating and spray coating, therefore, the coating is high in construction efficiency.

Description

[0001] technical field [0002] The invention relates to a coating technology, in particular to a super-weather-resistant, wear-resistant and anti-icing wind power blade coating and a preparation method thereof, which are suitable for long-term anti-icing coating of wind power generator blades. Background technique [0003] Most of the fan blades are made of epoxy fiberglass, and there are also unsaturated polyester resin composite materials, which have the advantages of light weight, good mechanical properties, and low cost, but there are still some shortcomings: such as poor weather resistance, poor wear resistance, etc. . Wind turbines are mostly located in deserts, mountains, coasts and seas far away from human habitation. The environment is harsh, and the blades need to withstand the erosion of various natural factors such as strong wind, sand, rain, frost, ultraviolet radiation, as well as the abrasion of high-speed operation. Coating protection technology has a wide ...
