Description
Technical field
The present invention is a kind of wind-driven generator group wind-wheel blade protective coating and preparation method thereof.Belong to coating composition, particularly the coating composition based on the multipolymer of the compound that a plurality of unsaturated aliphatic bases are arranged of contain fluorine atoms.
Technical background
Non-renewable fossil energy crisis makes the utilization of inexhaustible clean energy wind energy cause global attention, and the wind power generation plant development is rapid, and wherein the development of China's wind-powered electricity generation is particularly noticeable.China has heavy demand to wind power plant.Wind wheel blade is one of key core parts of wind power generating set, and the equipment that accounts for drops into about 20% of total cost, effectively controls the manufacturing cost of wind wheel blade, and prolonging its work-ing life is one of important channel that reduces the wind-power electricity generation total cost.Wind power plant build desert, sea and coastland mostly in, and these area surroundings are abominable, and wind wheel blade is bearing sandstone impact, windsand mill corrosion, strong UV-irradiation in operational process, significantly day and night temperature impacts and the soda acid erosion.Technical requirement to wind wheel blade external coating protective coating is unusual harsh.
The environment that wind wheel blade faces is abominable, and the protective layer of in most cases can not reforming, so the requirement to safeguard system is relatively stricter, fan blade coating need have stronger sticking power, wear resistance preferably, can improve the ability of blade ultraviolet aging resistance, the erosion of anti-dust storm, moisture-proof heat and resisting salt fog corrosion, can adapt to wind energy turbine set user demand under the different extreme weather conditions, guarantee the design service life in 20 years of wind wheel blade.
Publication number is that the patent application of CN101613564A discloses " a kind of wind power generation blade with protective coating and preparation method " it utilizes the base-material of hydroxyl acrylic resin as wind power generation blade surfacecti proteon coating, is that solidifying agent prepares protective coating for aerogenerator vanes with HDI biuret and the trimerical mixture of HDI.Acrylic resin paint has that look shallow is, weather-proof, and the Nai Baose gloss retention is strong, and characteristics such as the paint film fullness ratio is good, but acrylic resin is water-fast, solvent resistance is poor, and is not wear-resistant, and has the deficiency of " hot sticky cold crisp ".Above-mentioned deficiency has limited its application in the wind-powered electricity generation paint field.
Publication number is that the patent application of CN101665655A discloses a kind of " preparing high-performance wind-power coating with the organic fluorinated silicone modified elastic polyurethane urea resin ".The fluorine silicon modified polyurethane urea resin coating that this application prepares with the pure and mild polyether Glycols of polyester polyols and the amino fluorinated polysiloxane of end etc., it is functional, weak point is, the production cost of the raw materials such as the amino fluorinated polysiloxane of end that this coating is used is higher, the source is not enough, and the complicated process of preparation of coating has been used deleterious dimethylbenzene in its solvent.
At present, the wind wheel blade protective coating of employing is mainly polyurethane resin coating.Urethane resin has fabulous resistance to low temperature and elastomeric property, and is wear-resisting, corrosion-resistant, but UV resistant irradiation performance and ageing-resistant performance are not good enough, is difficult to work-ing life reach 20 years.
Fluorocarbon resin has splendid weathering resistance, ageing resistance, erosion resistance, stronger wear resistance and good sticking power, can satisfy the requirement of wind wheel blade protective coating.Publication number is that the patent application of CN101538434A discloses the protection that " a kind of fluorocarbon finish paint for corrosion protection of wind power equipment and preparation method thereof " is used for wind power tower drum, but Shang Weijian is with two component fluorocarbon coatings document and the patent report as the wind wheel blade protective coating.
Summary of the invention
The technical problem to be solved in the present invention is: overcome above-mentioned weak point of the prior art, a kind of have splendid ultraviolet-resistant aging, wear resistance, anti-staining property, excellent corrosion resistance are provided, snappiness is good, the wind-driven generator group wind-wheel blade protective coating of strong adhesion satisfies the technical requirements of work-ing life 〉=20 year.
