摘要: 风力发电是结构胶粘剂的新兴应用领域,在风电叶片的生产、组装、部件制造中有着广泛的应用,是风电叶片整体结构中的关键组成。有效地分析评价风电叶片用结构胶粘剂对于保证叶片的质量极为重要。胶粘剂的流变性是评价其质量和工艺性能的关键因素,其中粘度和触变性是两个极为重要的表征量。通过对风电叶片用结构胶粘剂在不同测试条件下的粘度和触变性试验,总结不同测试条件对胶粘剂粘度及触变性评价的影响,并提出使用触变环法评价结构胶粘剂的触变性的方法。经过分析表明,触变环法能够定性定量地表征胶体的触变性。

Abstract: The application of the structural adhesive is flourishing in wind power generation. The structural adhesive is a key component and has been widely applied in the production, assembly and parts manufacturing of the wind turbine blades. So it is extremely important to guarantee the quality of wind turbine blades based on an effective evaluation about the rheology of the structural adhesives. Since the viscosity and thixotropy are the two extremely important characterizations of rheology, the effect of different testing conditions on the viscosity and thixotropy has been summarized through carrying out a series of testing, and furthermore, the way of evaluating the thixotropy about the structural adhesives utilizing thixotropic loop has been proposed. A series of analyses show that the thixotropy of the structural adhesive can be qualitatively and quantitatively evaluated through the way of thixotropic loop.

Key words: structural adhesive, viscosity, thixotropy, wind power blades
