Description

Technical Field

[0001] This utility model relates to the field of aluminum composite honeycomb panel technology, and in particular to a high-strength aluminum composite honeycomb panel. Background Technology

[0002] Aluminum honeycomb composite panels are a new type of building decoration material with aluminum honeycomb as the core layer, mainly used in the field of building wall decoration. Its structure adopts aerospace material technology, consisting of two layers of aluminum plates bonded to the aluminum honeycomb core with adhesive to form a sandwich layer, covered with a 3-5mm thin natural stone slab, and reinforced with a high-strength glass fiber membrane to enhance structural stability;

[0003] Bimetallic composite materials consist of two different metals. Through the synergistic effect of these materials, the properties of each metal can be fully utilized to improve the overall performance of the material. 304 stainless steel / pure aluminum bimetallic composites are a common type of composite material, possessing excellent corrosion resistance, strength, and toughness. They are widely used in aerospace, automotive manufacturing, and other fields. Honeycomb panels made from this composite material exhibit even higher strength and toughness.

[0004] Conventional panels and honeycomb cores are bonded together with adhesives. Due to the honeycomb structure of the honeycomb core, the bonding contact area between it and the panel is relatively narrow, and the corresponding bonding strength is relatively weaker compared to the bonding of two flat panels. There is a risk of delamination during long-term use. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength aluminum composite honeycomb panel that can increase the contact and bonding area, improve the bonding strength, and avoid delamination during long-term use.

[0006] To achieve the above objectives, a high-strength aluminum composite honeycomb panel is provided, comprising: a composite honeycomb core, wherein zinc-aluminum alloy transition plates are symmetrically and parallelly mounted on the upper and lower sides of the composite honeycomb core, and honeycomb-shaped grooves are formed on opposite sides of the zinc-aluminum alloy transition plates by hot pressing. The composite honeycomb core is embedded in the corresponding honeycomb-shaped grooves and is fixedly bonded to the zinc-aluminum alloy transition plates by adhesive. The opposite side of the zinc-aluminum alloy transition plates is set as a smooth plane and a panel is fully bonded to it by adhesive. By installing zinc-aluminum alloy transition plates between the composite honeycomb core and the panel, the panel is made to fit smoothly. The side of the panel is a smooth plane and is fully bonded and fixed to the panel with adhesive. The side that contacts the composite honeycomb core is first formed into a honeycomb groove by hot pressing and then embedded and fixed to the composite honeycomb core with adhesive. This increases the contact and bonding area between the two and improves the bonding strength. In addition, the zinc-aluminum alloy used has a relatively low melting point and a relatively low hot pressing temperature. The composite honeycomb core can be directly used as the hot pressing mold, which is simple and convenient and reduces energy consumption. Moreover, the zinc-aluminum alloy transition plate is only used as an adhesive transition material. The strength of the composite plate is provided by the panel and the composite honeycomb core and does not affect the overall strength after assembly.

[0007] According to the high-strength aluminum composite honeycomb panel, the opposite side of the panel is covered with a decorative thin plate. This protects the panel while enhancing its decorative appeal.

[0008] According to the high-strength aluminum composite honeycomb panel, both the composite honeycomb core and the panel are made of 304 stainless steel / pure aluminum bimetallic composite material, which improves the overall composite strength.

[0009] According to the high-strength aluminum composite honeycomb panel, the decorative thin panel is made of natural stone and fixed to the panel with adhesive. This enhances the naturalness and aesthetics of the decoration.

[0010] According to the high-strength aluminum composite honeycomb panel, the depth of the honeycomb grooves in the zinc-aluminum alloy transition plate is set to twice the thickness of its flat plate. This ensures a deep fit and bonding while avoiding excessive increase in the overall thickness.

[0011] The above-mentioned solution has the following beneficial effects:

[0012] In this invention, a zinc-aluminum alloy transition plate is installed between the composite honeycomb core and the panel. The side of the plate that contacts the panel is a smooth plane and is fully bonded and fixed to the panel with adhesive. The side that contacts the composite honeycomb core is first formed into a honeycomb-shaped groove by hot pressing and then embedded and bonded to the composite honeycomb core with adhesive. This increases the contact and bonding area between the two and improves the bonding strength. In addition, the zinc-aluminum alloy used has a relatively low melting point and a relatively low hot pressing temperature. The composite honeycomb core can be directly used as the hot pressing mold, which is simple and convenient, reduces energy consumption, and the zinc-aluminum alloy transition plate is only used as an adhesive transition material. The strength of the composite plate is provided by the panel and the composite honeycomb core and does not affect the overall strength after assembly.
