Effect of Adhesive on Aluminum Honeycomb Panel

①aluminum honeycomb panel采用聚氨酯、环氧树脂类室温固化胶粘剂生产的aluminum honeycomb panel，其粘接强度低，对于蜂窝芯边长为4mm, the panel thickness is1mm, the total thickness is10mmof aluminum honeycomb panels measured180°Peel strength is4N/mmLeft and right. This aluminum honeycomb panel adhesion, weather resistance are poor, the use1The bonding performance decreased significantly after the year. The aluminum honeycomb panels produced by this process are not suitable for outdoor use, but can be used for indoor decorative partitions.

②The bonding strength of aluminum honeycomb panel produced by epoxy film process is low, and the side length of honeycomb core is4mm, the panel thickness is1mm, the total thickness is10mmof aluminum honeycomb panels measured180°Peel strength is4N/mmAbout, however, its bonding performance is good weather resistance, the use1After the year its peel strength decreased very little. The disadvantage is that the bonding layer of the aluminum honeycomb panel is brittle, and the aluminum honeycomb panel will be layered after long-term vibration.

③The bonding strength of aluminum honeycomb panels produced by the continuous composite process of thermoplastic film is the former2The aluminum honeycomb panel produced by the process.3-5times, for the side length of the regular hexagonal honeycomb core is4mm, the panel thickness is1mm, the total thickness is10mmof aluminum honeycomb panels, the measured180°The peel strength value is18N/mmLeft and right. Its adhesion, good weather resistance, the use1After the year its peel strength decreased very little.

由于是连续生产，aluminum honeycomb panel效率高，可满足短期大批量供货要求。这种工艺的缺点是所采用的平面连续热复合机设备价格高，投资巨大。热塑性胶膜是一种特殊热熔胶膜，胶膜本身要有很高的内聚强度和拉伸强度，这样可保证aluminum honeycomb panel的粘接牢固。如果采用一般的热熔胶膜，其粘接强度很低，180°Peel strength values are only3N/mm。
