Description

Technical Field

[0001] This utility model relates to the field of aluminum plates, and more specifically, to a waterproof and moisture-proof honeycomb aluminum plate. Background Technology

[0002] Honeycomb aluminum panels are a type of metal composite panel developed based on aerospace technology. They are lightweight, high-strength, sound-insulating, and heat-insulating, and are widely used in environments with high humidity, rain, and water immersion, such as building exterior walls, ship cabins, and underground engineering. Honeycomb aluminum panels adopt a "honeycomb sandwich" structure, which is made of high-strength alloy aluminum plates as the face and bottom plates and honeycomb core layers bonded together with adhesives. After long-term use, the adhesive will age, leading to moisture intrusion. When the humidity is high, the adhesive is prone to failure, which may cause the honeycomb aluminum panels to delaminate. Utility Model Content

[0003] The purpose of this utility model is to provide a waterproof and moisture-proof honeycomb aluminum panel to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A waterproof and moisture-proof honeycomb aluminum panel includes a base plate, a panel, and a honeycomb core layer disposed between the base plate and the panel. The four edges of the base plate and the panel are provided with folded edges that bend toward the honeycomb core layer and cover the sides of the honeycomb core layer. The connection between the base plate and the panel and the corresponding connection between the base plate and the honeycomb core layer are sealed by a number of welding points.

[0005] Furthermore, the joint of the folded edge is filled with sealant and fixed by adhesive bonding.

[0006] Furthermore, a sealed cavity is formed between the honeycomb core layer and the side of the folded edge unit, and a polyurethane sealing strip is pre-placed in the sealed cavity.

[0007] Through the above technical solution, polyurethane sealing strips can effectively prevent moisture from entering the honeycomb core layer.

[0008] Compared with the prior art, the present invention has the following beneficial effects: Welding prevents the panel and honeycomb core layer from separating. The external folds and sealant form a waterproof barrier, preventing moisture from entering through gaps in the joints. The internal polyurethane sealing strip acts as a second layer of waterproof and moisture-proof barrier, effectively preventing corrosion of the honeycomb core layer. Attached Figure Description

[0009] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0012] The utility model will now be further described with reference to the accompanying drawings and specific embodiments: Example 1: Please see Figures 1 to 3 A waterproof and moisture-proof honeycomb aluminum panel includes a base plate 1, a panel 2, and a honeycomb core layer 3 disposed between the base plate 1 and the panel 2. The four edges of the base plate 1 and the panel 2 are provided with folded edges 4 that bend towards the honeycomb core layer 3 and cover the sides of the honeycomb core layer 3. The connection between the base plate 1 and the panel 2 and the corresponding connection between the base plate 1 and the honeycomb core layer 3 are sealed by a number of welding points 5. When the glue fixing the honeycomb core layer 3 to the base plate 1 and the panel 2 comes off, the welded parts can still ensure that the honeycomb aluminum panel will not have the risk of delamination. Moreover, the welding points 5 form a metal seal, which can effectively protect the honeycomb core layer 3 from the intrusion of moisture.

[0013] Sealant 6 is filled at the joint of the folded edge 4 and fixed by the sealant 6. When the aluminum plate folded edge 4 is sealed, there will be some gaps when the folded edge 4 wraps the honeycomb core layer 3. These gaps will allow moisture in the air to penetrate into the honeycomb core layer 3 inside the honeycomb aluminum plate, which will cause the honeycomb core layer 3 to be corroded and thus damaged. Filling these gaps with sealant 6 can form a physical barrier to prevent moisture from entering the honeycomb core layer 3 through the tiny gaps.

[0014] A sealed cavity is formed between the honeycomb core layer 3 and the side of the folded edge 4. A polyurethane sealing strip 7 is pre-placed in the sealed cavity. When the folded edge 4 of the aluminum plate is sealed, a sealed cavity is formed with the inner honeycomb core layer 3. The polyurethane sealing strip 7 is placed in the sealed cavity. The polyurethane sealing strip 7 can provide durable elasticity. When the outer sealant 6 ages and cracks or is damaged, the inner polyurethane sealing strip 7 can still prevent moisture from entering the honeycomb core layer 3, thus strengthening the protection capability.

[0015] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "setting", "connection", "fixing", "screw connection", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0016] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
