Description
Technical field
The present embodiments relate to the coating industry in chemical industrial field, more particularly to a kind of working life adjustable wind-powered electricity generation
Blade coating and preparation method thereof.
Background technology
Wind energy is a kind of energy of green non-pollution, as traditional fossil resources reserves gradually reduce and its shadow to environment
Sound increasingly increases, the utilization Fast Growth of wind energy.Wind electricity blade is one of key core part of wind power generation plant, existing
There are most of blades under technology to be made using epoxy glass fiber composite, for the blade of MW class close to 50 meters, bigger can
Reach 80 meters, maintenance cost is high, and the area generally geographical position of wind energy enrichment is remote, has inconvenient traffic, therefore blade coating will
Overlength protection phase effect is sought, blade can be protected to face the abrasion of dust storm rainwater, ultraviolet, high/low temperature alternation, damp and hot, salt in running
The destructive factors such as mist, torsional deformation.Linear velocity is very high when wind electricity blade is run, and vane tip is up to 100Km/h, in wind sand environment
In easily wear.
Existing blade coating is most commonly used that the supporting polyurethane finish of solvent borne polyurethane priming paint, and this kind of coating is often consolidated
Content is relatively low, and the organic solvent used is more, and not only VOC imposes starting point close to the even more than coating consumption tax, it is also necessary to more
Road application can be only achieved required film thickness, dry slow, long construction period.
Polyaspartic Ester-Based Coatings are to plant a new material, not only weather-proof wear-resisting wet-heat resisting salt spray resistance, and making
