Embodiment 1

[0025] The wind power generator blade special coating of the present embodiment comprises: solid content in 80%~70% hydroxyacrylic resin 40kg, titanium dioxide R25kg, quartz powder 1250 order 30kg, clay 0.5kg, wax paste 0.5kg, wax powder 9322F 2kg, 0.5kg of 4050 dispersant, 4500.3kg of leveling agent, 1kg of defoamer 6800, 0.5kg of 10% organotin, 13kg of butyl ester and a small amount of color masterbatch. After the above-mentioned ingredients are prepared, mix them with HDI at the ratio of amino value 6-9:1.

[0026] Construction process:

[0027] (1) After mixing the special paint for wind turbine blades and curing agent HDI according to the amino value calculation ratio of 6-9:1, paint on the two half-moulds of the blade mould, and it needs to be painted twice to form Gel coat layer, the thickness of the gel coat layer is 500μm, if there are other specific needs, it can be painted three times to make the thickness of the gel coat layer more than 500μm;

[0028] (2) The ge...

Embodiment 2～ Embodiment 4

[0033] The components of the wind power generator blade special coating of each embodiment are shown in Table 1, and the construction technology of each embodiment is basically the same as that of Example 1, the difference being that the different proportioning of each component of each embodiment makes the gel coat The tack-free time and the heat-curing time of the leaves were changed.

Abstract

The invention discloses a special paint for wind turbine blades and a construction process thereof, which are mainly designed for the performance defects of the existing paint and the disadvantages of complicated paint construction, labor and time consuming and the like. The special coating for wind turbine blades is composed of a main material and an auxiliary material, and the ratio of the main material and the auxiliary material by weight is 75-85:15-25; the main material is composed of the following raw materials in parts by weight: solid 30-40 parts of hydroxy acrylic resin with a content of 80-70%, 17-27 parts of whitening agent, and 21-31 parts of filler for improving the hardness of the paint film. The special paint for wind turbine blades needs to be mixed with a curing agent in proportion when used. The mixed paint is pre-coated on the blade mold to form a gel coat layer, and the mold casting and coating of the blade are completed at the same time by using the gel coat transfer technology. The construction is simple and convenient, saving time and effort.

Description

technical field [0001] The invention relates to a paint and a construction process, in particular to a special paint and a construction process for wind-driven generator blades. Background technique [0002] The most critical and core part of a wind turbine is the blade. The design and processing technology of the blades determine the performance and power of the wind turbine, and also determine the cost of the wind turbine. Since wind turbines are mostly installed in places with relatively harsh environments, the blades must not only withstand the erosion of gas, the impact of sand and stones, but also face strong ultraviolet radiation, large temperature differences between day and night, and acid, alkali, and water vapor in the process of working. erosion. This requires the blade to have good performance: material performance, processing technology and strong protection performance of the coating. [0003] At present, the paint on the outer layer of the blade is more ge...
