Anti-icing coating for wind turbine blade, and preparation method of anti-icing coating

Abstract

The invention relates to an anti-icing coating for a wind turbine blade, and a preparation method of the anti-icing coating for the wind turbine blade. The anti-icing coating for the wind turbine blade consists of a component A and a component B, wherein the mass ratio of the component A to the component B is 1.5:1. The component A comprises the following components: tetrafluoro-resin, a dispersant, rutile type titanium dioxide, carbon black, nano alumina, a defoamer, a leveling agent, a flatting agent, a surface modifier, butyl acetate, propylene glycol methyl ether acetate, and the component B is hexamethylene diisocyanate (HDI) trimer. The preparation method of the anti-icing coating for the wind turbine blade comprises the following steps: preparing the component A, preparing the component B, and mixing the component A and the component B in the mass ratio of 1.5:1 to prepare the coating, and the anti-icing coating for the wind turbine blade has the advantages of excellent weatherability, wear resistance and flexibility property and also has outstanding anti-icing performance.

Description

technical field [0001] The invention relates to the technical field of coating chemicals, in particular to an anti-icing coating for fan blades and a preparation method thereof. Background technique [0002] As a renewable, non-polluting and sustainable green energy, wind energy is abundant, inexhaustible and inexhaustible. The large-scale development and utilization of wind energy will effectively reduce the use of fossil energy, reduce greenhouse gas emissions, and protect the environment. Vigorously developing wind energy has become an important choice for governments around the world. [0003] my country is rich in wind energy resources. With the vigorous development of my country's wind power industry, the coatings and technologies for fan blades are constantly improving. Due to the relatively late start of my country's wind energy technology, the coating technology for fan blades was initially imported from abroad, and the development speed was slow. However, under th...

Problems solved by technology

However, because the fan blades are easy to freeze in winter, which affects the power balance, and the fan blades have a high speed and a large centrifugal force. In the case of serious imbalance, the blades will break, causing heavy losses, and even endangering personal safety. The consequences are disastrous! For a long time, the anti-icing problem of fan blades has plagued fan blade manufacturers in my country, seriously hindering the development of wind energy and the advancement of technology in our country

[0004] How to solve the problem of fan blade icing has always been a research hotspot at home and abroad. In recent years, the following solutions have emerged: one method is to use the centrifugal force generated when the impeller rotates to throw off the ice, but it will increase the load on the unit. It leads to the aging of accelerated components; the second is to add heating wires to the blades to heat the blades, which requires consideration of lightning protection and heating temperature issues, and in actual implementation, due to insufficient heating, local or edge areas are severely frozen; three. It is to paint the blades black, but the high temperature of the blades in summer may deform the blades and affect the power generation efficiency
