Abstract

A class of amine-containing associating polymers (APE) has been found to be a promising adhesive on low surface energy substrates. The peel strength of two APE samples of different molecular weight is measured over a large range of peel rates. A quantitative model has been developed to predict the peel performance of APEs by interrelating elongational viscoelastic properties and peeling performance. The model considers the effect of shape variation of a polyethylene substrate in T-peel mode by introducing a shape parameter

. Besides

and the viscoelastic elongational properties, cohesive and adhesive fracture criteria are required for determining the peel strength and the transition from cohesive to adhesive failure. Different fracture criteria were evaluated and selected purely based on the basis of adequately describing the experimental results. A single set of fracture criteria is found to describe the experimental results well, offering an effective way for adhesive property optimization.

胺缔合聚合物的剥离强度（内聚/粘接）

一类含胺缔合聚合物（APE）是一种很有前途的低表面能基材粘合剂。两种不同分子量的APE样品的剥离强度在很大的剥离率范围内进行了测量。建立了一个定量模型，通过相互关联的拉伸粘弹性和剥离性能来预测猿猴的剥离性能。该模型通过引入形状参数，考虑了聚乙烯基板在180度剥离模式下形状变化的影响。除了粘弹性拉伸性能外，还需要黏聚和粘接断裂准则来确定剥离强度和从黏聚到粘接的过渡。在充分描述实验结果的基础上，评估和选择不同的断裂准则。找到了一套能很好地描述试验结果的断裂准则，为胶粘剂性能优化提供了有效途径。
