The invention provides a preparation method of an aluminum honeycomb core and an aluminum honeycomb panel. Through holes and through grooves are opened in the process of preparing the aluminum honeycomb core, so that when the honeycomb core and the aluminum plate are welded, the residues in the honeycomb core can be fully discharged Air, to avoid oxidation of the aluminum foil of the honeycomb core during the high temperature welding process, and at the same time further coat the first adhesive and the second adhesive on the different areas where the aluminum foil is bonded. The edge of the area, with good joint strength and durability, the second adhesive is applied in the middle most of the area of the bonding area, the second adhesive has good interfacial properties, can provide good interface with oil or water The cohesive force and fast curing effect of the two are used together to improve the quality of the honeycomb core processing and the bonding strength of the honeycomb core. |
