Problems solved by technology

At present, the preparation method of honeycomb panels is generally to vacuum-weld the stretched aluminum honeycomb core with the aluminum plates on both sides, but because there is air remaining between the multi-layer aluminum foils that make up the aluminum honeycomb core, the oxygen in the air will be on the aluminum foil and the aluminum foil. Oxidation of the connection between the honeycomb core affects the life of the honeycomb core

Abstract

The invention provides preparation methods of a corrosion-resisting aluminum honeycomb core and an aluminum honeycomb plate. In a process of preparing the aluminum honeycomb core, a through hole and athrough groove are formed, so that when a honeycomb core is welded with an aluminum plate, residual air in the honeycomb core can be sufficiently discharged, and a condition that an aluminum foil ofthe aluminum core in a high-temperature welding process is oxidized is avoided; meanwhile, an exposed surface of the aluminum foil is coated with a corrosion-resisting layer, so that the oxidization-resisting and corrosion-resisting capability of the aluminum foil is improved, the weather resistance of the aluminum honeycomb core is improved and the service life of the aluminum honeycomb core is prolonged.

Description

technical field [0001] The invention relates to the construction field, in particular to a method for preparing a corrosion-resistant aluminum honeycomb core and an aluminum honeycomb panel. Background technique [0002] The honeycomb structure has a large strength-to-weight ratio, can meet the requirements of high strength with a small cross-section, and can greatly reduce the self-weight of the structure itself. Therefore, the honeycomb structure has the advantages of good structural stability, impact resistance and cushioning performance. The honeycomb panel composed of double-layer aluminum plate sandwiching the honeycomb structure core has a series of advantages such as light weight, high specific strength, high rigidity, good stability, heat insulation, sound insulation and no pollution. Widely used in trains, ships, construction and other fields. At present, the preparation method of honeycomb panels is generally to vacuum-weld the stretched aluminum honeycomb core ...
