Problems solved by technology

At present, in this emerging field, mostly solvent-based coatings are used. For example, the patent with the publication number CN106243981A discloses a high wind and sand erosion-resistant wind power blade coating and its preparation method. In the preparation process, butyl acetate, xylene or One or several kinds of methyl nylon acid are used as solvents, but solvent-based coatings are coatings prepared from organic solvents as dispersion media, which have problems such as polluting the environment, wasting energy, and high costs.

Description

technical field [0001] The invention relates to the technical field of water-based coatings, in particular to a water-based organosilicon-modified fluorocarbon wind power blade coating and a preparation method thereof. Background technique [0002] Wind energy, as a renewable and clean energy, is getting more and more attention today. Wind power has a bright prospect in China, so there is also a large market demand for corresponding wind power blade coatings. The national 863 plan has a special support for the localization of blade coatings. Wind turbine blade coatings must have excellent weather resistance, heat and humidity resistance, freezing resistance, low VOC, etc. in addition to conventional good mechanical properties. At present, in this emerging field, mostly solvent-based coatings are used. For example, the patent with the publication number CN106243981A discloses a high wind and sand erosion-resistant wind power blade coating and its preparation method. In the p...
