Embodiment 1
[0021] A preparation method of high-strength aluminum honeycomb panel, the preparation method comprises the following steps:
[0022] (1) Select a 1060 aluminum strip with a thickness of 0.1mm, and press the aluminum strip into a half-hexagonal zigzag aluminum strip with a sawtooth angle of 120°. After annealing the pressed semi-hexagonal aluminum strip, use 302 The industrial glue is cemented into a honeycomb core. After curing for 24 hours, it is polished to remove the burr, and the honeycomb core is obtained for use;
[0023] (2) Select two 1060 aluminum alloy plates with a size of 1.5mm as the upper and lower panels of the aluminum honeycomb panel. After the panels are hot-rolled, cold-rolled, coarsely ground, finely ground, and dried, they are annealed at 210°C Treat for 30 minutes;
[0024] (3) Degreasing, pickling, rinsing in cold water, anodizing, rinsing in cold water, sealing treatment, rinsing in cold water, drying the panel obtained in step (2), and set aside;

[0028] A preparation method of high-strength aluminum honeycomb panel, the preparation method comprises the following steps:
[0029] (1) Select a 1060 aluminum strip with a thickness of 0.2mm, and press the aluminum strip into a half-hexagonal zigzag aluminum strip with a sawtooth angle of 120°. After annealing the pressed semi-hexagonal aluminum strip, use 302 The industrial glue is cemented into a honeycomb core. After curing for 24 hours, it is polished to remove the burr, and the honeycomb core is obtained for use;
[0030] (2) Select two 1060 aluminum alloy plates with a size of 2mm as the upper and lower panels of the aluminum honeycomb panel. After the panels are hot-rolled, cold-rolled, coarsely ground, finely ground, and dried, they are annealed at 200°C 30min;
[0031] (3) Degreasing, pickling, rinsing in cold water, anodizing, rinsing in cold water, sealing treatment, rinsing in cold water, drying the panel obtained in step (2), and set aside;

Abstract
The invention relates to aluminum honeycomb plates, in particular to a preparation method of a high-strength aluminum honeycomb plate. The preparation method includes the steps: (1) selecting an aluminum strip, pressing a semi-hexagon to obtain a honeycomb core; (2) selecting an aluminum honeycomb plate, and manufacturing an upper panel and a lower panel; (3) performing surface treatment on the panels; (4) performing surface treatment on a composite brazing plate; (5) placing the upper panel, the lower panel and the composite brazing plate into a constant-temperature incubator to perform treatment, and performing pressuring and bonding to obtain the high-strength aluminum honeycomb plate. The high-strength aluminum honeycomb plate effectively overcomes the shortcoming of poor strength of an existing aluminum honeycomb plate to some extent.
Description
technical field [0001] The invention relates to an aluminum honeycomb panel, in particular to a preparation method of a high-strength aluminum honeycomb panel. Background technique [0002] Aluminum honeycomb panels are suitable for civil buildings, vehicle and ship decoration, etc. It is the application of aviation and aerospace materials in the field of civil construction. The entire processing process is completed in a modern factory, using hot-press forming technology, due to the high heat conduction value between the aluminum skin and the honeycomb, the thermal expansion and contraction of the inner and outer aluminum skins are synchronized; there are small holes on the honeycomb aluminum skin, so that the gas in the board can be freely Flow; the slide-mount buckle system expands and contracts without causing structural deformation. [0003] In the Chinese published patent application CN101623942, a magnesium-aluminum honeycomb panel and a method for preparing the mag...
