Abstract

The invention discloses a thick paste quick-drying type weather-resistant and wear-resistant coating for wind turbine blades and a preparation method thereof, the coating takes poly-asparaginic acid ester and elastic resin-modified aliphatic isocyanate as base materials, a nano-material is adopted for being effectively bonded with a resin matrix, and appropriate auxiliaries and additives for enhancing the performances of the coating. The thickness of a film which is formed by the coating for the wind turbine blades once can achieve 300 mu m; furthermore, the drying speed is fast and the coating is less prone to bubbling; the weather resistance is excellent, and the coating has higher tensile strength and elongation at break, and prominent wear resistance and impact resistance; the performances of water resistance, chemical product resistance, wet heat resistance, salt mist resistance and high and low temperature resistance are excellent; and the coating has certain anti-pollution and anti-icing properties. The construction efficiency of the coating is high, the performances of the coating are particularly suitable for wind field environments in China, the service life of a unit can be prolonged and the maintenance cost can be reduced.

Description

[0001] The invention relates to an anti-corrosion coating technology, in particular to a thick paste quick-drying weather-resistant and wear-resistant coating for wind power blades and a preparation method thereof. Background technique [0002] Wind turbines are mostly located in deserts, mountains, coasts and seas away from human habitation. The environment is harsh. The blades need to withstand the erosion of ultraviolet radiation, strong wind and sand, rain, frost and other natural factors, as well as the abrasion of high-speed operation (the blades are the sharpest when the blades are running normally. The linear speed can reach 80m / s, and the average running time is 7000h / y. The air friction is 5~10 times that of ordinary cars, and the sand or raindrops in the wind will have a strong impact on the blade surface). Therefore, it is necessary to effectively coat and protect the blade surface to improve its anti-erosion ability, thereby increasing the service life of the entir...
