Crosslinking agent for wind turbine blade protection coating
Wind power is a clean, renewable energy, and the development and utilization of wind energy has become the consensus of the global energy industry. More and more strict in accelerating economic development and environmental protection, under the big background of the development of wind power as a world, one of the important measures for sustainable development has the potential to be the future is the most important alternative energy sources, widely followed, a market with enormous potential. With the implementation of China's renewable energy law in 2006, wind power in China has been growing.
Wind power plant is mainly composed of gearbox, generator set, Kentucky and substation and so on, the fan blade is the key element of the generating set, cost 15% ~ 20% of the cost of wind power the device.
Blade material according to different blade length and choose different composite material, at present is the widespread use of light quality, good mechanical properties and lower cost of epoxy FRP blade, but its weather resistance, abrasion resistance is poor, the wind farms in China are mostly located in the northwest, north China, northeast, southeast coastal and island area, climate conditions, this requires blade coating coating protection.
According to the characteristics of the blade work and using environment, blade coating in addition to the common good coating adhesion, decorative, but also meet the strong weatherability, super wear resistance, good flexibility, excellent high and low temperature resistance, low surface energy, etc. There are few domestic research reports, which are very inconsistent with the current situation of high speed development of wind energy industry in China.
Cold - resistant and cold - resistant materials are cold-rolled steel sheet, specifications: 120mm x 200mm x 2mm; Wear resistant substrate on the specified aluminum plate; All the rest are epoxy glass plates.
Screening of the TMP dosage of polyols, the type and content of fluorine resin test and match ratio of the amount of paint material test, a wind-power blades protective coating is developed with the crosslinking agent, the wind power blade protection coating with crosslinking agent and the traditional HDI trimer and commercially available elastic polyurethane crosslinker crosslinked coating than in weather resistance, abrasion resistance, mechanical properties, hydrolysis stability and composite substrate adhesion has obvious advantages, can cooperate with high-performance hydroxyl component, the coating product performance is prepared.

Of wind-power blades with material, working environment and characteristic analysis, need to use the blade clear coating to protect, and put forward the blade to the specific requirements of the protective coating, comparison results show that wind power blade protection coating with crosslinking agent can be used for the protection coating of wind-power blades.
The epoxy resin paint can be obtained from a single unit and a bi-component product. Many of the features provided by the two-component epoxy resin are similar to polyurethane. They are durable and chemical resistant, but offer limited uv protection compared to linear polyurethane.
Bicomponent linear polyurethane (LP) paint provides the most lasting protection. As a (LP) pigment or transparent coating can provide excellent uv protection, gloss retention, wear resistance and good compatibility with epoxy resin.
However, compared to other types of coating, they are expensive, require more application skills and lead to greater health risks, especially when sprayed.
Primer is available on many occasions. Most of the primer systems are compatible with epoxy resin and can be applied directly to prepared epoxy resin finishes. If you can be sure that their compatibility or a specific primer can be crosslinked or adhered to, this coating is recommended as a primer on the barrier coating.
Other paints are not recommended, including Marine LP coatings, under waterline. Primer usually don't need any help could combine to the epoxy coating film, although interactions at the bottom of the coating can be suitable for some professional requirements of the paint and high construction prime coat is at the bottom of the underlying hidden or defects. If you recommend a special primer on your paint or varnish, suggest using a given method to prepare the fiberglass. The corrosion of the substrate does not work well on the epoxy coating.
