Polyurethane paint used on windward sides of wind power blade machines, and preparation method thereof

Abstract

The invention discloses a polyurethane paint used on windward sides of wind power blade machines, and a preparation method thereof. The polyurethane paint comprises modified phenolic resin reinforced polyurethane, urea-formaldehyde resin, ethylene-vinyl acetate copolymer, an anti-settling agent, rutile titanium dioxide, flake graphite powder, methyl methacrylate, coumarone, zinc oxide, kaolin, diethylene glycol, an aromatic hydrocarbon oil, a stabilizing agent, silicon dioxide, an antifoaming agent, a dispersant, a base material wetting agent, and a bactericide. The polyurethane paint is long in service life, and high in using safety, is capable of reducing blade production cost and maintenance cost in operation process. It is confirmed by a plurality of performance tests that the polyurethane paint is excellent in adhesive force, wear resistance, weatherability, salt spray resistance, damp heat resistance, and flexibility, can be used on wind driven generator blades, and is capable of protecting operation of wind driven generator blades for a long term.

Description

technical field [0001] The invention relates to the technical field of coating chemicals, in particular to a polyurethane coating for the windward side of a wind blade machine and a preparation method thereof. Background technique [0002] With the development and application of renewable energy, wind energy has become one of the main energy sources in the world due to its rich resources, wide distribution, and cleanliness. The development of wind power and wind power industry has also attracted much attention. The blade is an important part of the wind turbine, and it is a device for capturing and converting wind energy. Its performance and service life directly affect the normal operation of the wind turbine and the efficiency of the system. Therefore, the reliability and safety of blades are particularly important, which is the key to ensure the normal operation of wind turbines. [0003] Due to the complex and changeable environment and climate of the wind field, when t...
