摘要: 模内涂装是提高风电叶片涂装效率的一种有效方式。相比模外涂层体系,风电叶片用模内涂层体系在工艺性能方面有一些特殊性要求。研究了三种聚氨酯模内胶衣在风电叶片中的工艺适用性,通过可操作性、占模时间、与玻璃钢之间的附着力、在实际叶片模具上的脱模性能以及脱模后对其覆盖的玻璃钢中灌注缺陷的可观察性等性能研究发现,其中两种聚氨酯模内胶衣适用于风电叶片的生产工艺过程。

Abstract: Using in-mold coatings is an effective way to improve the coating efficiency of wind turbine blades. There are some special requirements for the processing performance of the in-mould coating system compared with the outer-mould coating system for wind turbine blades. This paper studies the processing applicability of three kinds of in-mold polyurethane gel-coatings used in wind turbine blades. Through research on manipulability, in-mold time, pull-off strength between gel-coating and glass fiber reinforced epoxy composite, release properties in actual wind blade mold, and the observability of the defects in glass fiber reinforced composite covered by coating, it draws a conclusion that two kinds of in-mold polyurethane gel-coating are fit for the production process of wind turbine blades.

Key words: wind turbine blades, protective coating, in-mould coating, polyurethane, painting efficiency
