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.
