Process for improving bonding strength of aluminum honeycomb plates

Abstract

The invention discloses a process for increasing the bonding strength of aluminum honeycomb plates. The aluminum honeycomb plate comprises an upper plate, an aluminum honeycomb core and a lower platewhich are sequentially overlapped from top to bottom, the overlapped surfaces of the upper plate and the aluminum honeycomb core, and the overlapped surfaces of the lower plate and the aluminum honeycomb core are coated with a glue. The process comprises the following steps: (1) fixing the upper plate and the lower plate of the assembled aluminum honeycomb plate; and (2) moving the aluminum honeycomb core for a distance a, so that the glue is gathered on the outer edge of the hole grids of the aluminum honeycomb core. According to the process, glue is gathered on the outer edges of the hole grids of the aluminum honeycomb core, so that the contact area between the hole grids of the aluminum honeycomb core and the glue can be greatly increased, the bonding strength between the aluminum honeycomb core and the upper and lower plates is improved, the bonding strength of the aluminum honeycomb plate is improved, the gluing amount can be reduced on the premise of meeting the bonding strengthrequirement, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of composite panels, in particular to a process for increasing the bonding strength of aluminum honeycomb panels. Background technique [0002] Aluminum honeycomb panel refers to a composite panel with a three-layer structure of "aluminum panel / aluminum honeycomb core / aluminum panel". The aluminum panel and aluminum honeycomb core are bonded with an adhesive. This composite panel has high strength, light weight and no formaldehyde. It is widely used in the interior and exterior decoration of large buildings, as well as the compartment partitions of aircraft or ships, and is now further expanded to the fields of furniture panels and other fields. In the production process of existing aluminum honeycomb panels, glue is usually used to coat the side of the aluminum panel in contact with the aluminum honeycomb core, so that the two aluminum panels are laminated and bonded to the upper and lower ends of the alumi...

AI Technical Summary

Problems solved by technology

In the production process of existing aluminum honeycomb panels, glue is usually used to coat the side of the aluminum panel in contact with the aluminum honeycomb core, so that the two aluminum panels are laminated and bonded to the upper and lower ends of the aluminum honeycomb core respectively. However, this method The contact area between the cells at the root of the aluminum honeycomb core and the glue on the aluminum plate is relatively small, and the bonding strength between the two is not high. The role of aluminum plate connection
