Description

Technical Field

[0001] The present application relates to the technical field of aluminum veneers, and in particular to a honeycomb aluminum veneer. Background Art

[0002] Honeycomb aluminum veneers have been widely used in the construction field due to their light weight and high strength. Honeycomb aluminum veneers in the existing technology usually include a topcoat layer and an aluminum honeycomb core. The aluminum honeycomb core is placed between the two topcoat layers and bonded together by adhesive.

[0003] However, in actual application, the temperature inside and outside of the existing honeycomb aluminum veneer is inconsistent, resulting in unsynchronized thermal expansion and contraction. As the use time increases, the adhesive will become brittle due to large temperature changes, resulting in poor adhesion between the aluminum honeycomb core and the topcoat layer, thus affecting the service life of the honeycomb aluminum veneer. Summary of the Invention

[0004] In order to alleviate the brittleness problem of the adhesive due to large temperature changes, the present application provides a honeycomb aluminum veneer that can extend the service life of the honeycomb aluminum veneer.

[0005] This application provides a honeycomb aluminum veneer, which adopts the following technical solution:

[0007] By adopting the above technical solution, the setting of the honeycomb core makes the entire aluminum veneer more lightweight while maintaining good structural strength. Moreover, the honeycomb structure can effectively disperse external forces and improve the impact resistance of the aluminum veneer. Compared with the existing technology, by setting perforations on the honeycomb units, not only the overall weight can be reduced, but also the sound absorption and heat insulation properties of the material are increased, which helps to regulate internal stress and improve the durability and stability of the material. It can achieve the effect of consistent temperature inside and outside the honeycomb aluminum veneer, so that thermal expansion and contraction are synchronized, thereby alleviating the brittleness problem of the adhesive due to large temperature changes. In addition, the introduction of the chromium layer enhances the corrosion resistance of the aluminum plate, and the paint layer improves the surface appearance and weather resistance. In this application, the adhesive layer ensures a firm connection between the layers to form an integrated composite material, which helps to extend the service life of the honeycomb aluminum veneer.

[0008] Preferably, the baking varnish layer provided on the side of the chromized layer facing away from the honeycomb core is a fluorocarbon roller-coated baking varnish layer.

[0009] By adopting the above technical solution, the fluorocarbon roller coating paint layer has excellent corrosion resistance and long-term color retention, which can effectively extend the service life of the honeycomb aluminum veneer and maintain a long-term beautiful appearance, making the aluminum veneer suitable for a variety of harsh environments, so that the aluminum veneer can be used in scenes such as indoor and outdoor decoration and building curtain walls.

[0010] Preferably, the baking varnish layer provided on the side of the aluminum plate facing away from the honeycomb core is a polyester baking varnish layer.

[0011] By adopting the above technical solution, the polyester paint layer is lower in cost than the fluorocarbon roller paint layer, but also has good weather resistance and decorative properties, which helps to reduce the cost and provide different options.

[0012] Preferably, the adhesive layer is a two-component polyurethane curing adhesive.

[0013] By adopting the above technical solution, the two-component polyurethane curing adhesive has excellent bonding strength and weather resistance, which can ensure a strong bond between the aluminum plate, honeycomb core and other layers of materials, and improve the overall stability and durability of the product. At the same time, this type of adhesive generally meets environmental standards, does not contain harmful substances, is safe and harmless to the human body and the environment, and is suitable for the needs of green building and sustainable development.

[0014] Preferably, the plurality of honeycomb units are neatly arranged in parallel, and the honeycomb units are vertically provided with a through cavity.

[0015] By adopting the above technical solution, the honeycomb units are neatly arranged in parallel to form an orderly structure, which helps to enhance the overall stability and pressure resistance of the aluminum veneer. The setting of the through cavity can reduce the overall weight of the aluminum veneer, help to achieve the functions of sound insulation and heat insulation, and further make the temperatures inside and outside the aluminum veneer tend to be consistent, so that thermal expansion and contraction are synchronized, thereby achieving the purpose of extending the service life.

[0016] Preferably, the honeycomb unit is a hexagonal prism structure, and each of the honeycomb units has at least three sides with perforations.

[0017] By adopting the above technical solution, a honeycomb unit with a hexagonal prism structure can maximize the reduction of material weight while ensuring structural strength, thereby achieving efficient use of materials. In this application, each honeycomb unit has at least three sides with perforations. Such a design helps to enhance air circulation and further improve the heat insulation and sound insulation effects.

[0018] Preferably, it comprises a side frame, the inner side wall of the side frame is provided with a slide groove, the honeycomb unit placed near the slide groove is provided with a sliding member, and the sliding member is clearance-fitted with the slide groove.

[0019] By adopting the above technical solution, the introduction of side frames provides additional support for the honeycomb aluminum veneer, making the edge area of the aluminum veneer more stable. At the same time, it can achieve flexible connection between the honeycomb unit and the side frame, which is convenient for installation, disassembly and maintenance, and maintains the integrity of the structure. This application uses a micro-sliding installation system to prevent the aluminum veneer from causing structural deformation when it expands and contracts due to heat and cold, and maintains good flatness.

[0020] Preferably, one end of the sliding member is fixedly connected to the honeycomb unit, and a buffer sleeve is provided on the outer wall of the other end, and the end is in sliding connection with the sliding groove.

At the same time, it helps to achieve smooth sliding of the sliding part in the slide groove, improving the smoothness and accuracy of the operation.

[0022] In summary, this application includes at least one of the following beneficial technical effects:
