Abstract In this work, a thermoplastic adhesive used by automotive industries for bonding plastic components has been modified with iron oxide nanoparticles to ease the dismounting process. Two different processes have been considered for the joint dismounting, namely the already studied electromagnetic induction and an innovative microwave heating process. Besides the mentioned heating activation process, a full experimental plan has been designed that includes two different weight percentages (5% and 10%) of the nanoparticles and two alternative mixing methods: hand-mixing and extrusion methods. The mechanical performances and the separation tests have been assessed by using single lap joints. The adhesive joints prepared with the nanomodified adhesives and with the hand-mixing method presents a slightly larger value of the maximum strength due to the presence of small agglomerates that have been observed with scanning electron microscope analysis. On the other hand, the extrusion method gave a very uniform distribution of the particles within the adhesive matrix. Microwave and induction heating tests conducted on both the single lap joint and the adhesive itself showed that the joint separation and the melting of the adhesive are possible by using both adhesives prepared with the two mixing methods.

微波和感应工艺激活的增强型和可拆卸热塑性粘合剂接头的热机械特性

摘要 在这项工作中，汽车工业用于粘合塑料部件的热塑性粘合剂已用氧化铁纳米粒子改性，以简化拆卸过程。联合拆卸考虑了两种不同的工艺，即已经研究过的电磁感应和创新的微波加热工艺。除了提到的加热活化过程外，还设计了一个完整的实验计划，包括两种不同重量百分比（5% 和 10%）的纳米粒子和两种替代混合方法：手工混合和挤出方法。机械性能和分离试验已通过使用单搭接接头进行评估。由于使用扫描电子显微镜分析观察到的小团聚体的存在，使用纳米改性粘合剂和手工混合方法制备的粘合剂接头呈现出稍大的最大强度值。另一方面，挤出方法使粘合剂基质内的颗粒分布非常均匀。对单搭接接头和粘合剂本身进行的微波和感应加热测试表明，使用两种混合方法制备的两种粘合剂都可以实现接头分离和粘合剂的熔化。
