Description

Technical Field

[0001] This utility model relates to the field of metal composite panel technology, and in particular to a high heat insulation metal composite panel. Background Technology

[0002] Metal composite panels are favored by people because they save resources and costs, have superior comprehensive performance, are lightweight and environmentally friendly, and are suitable for multiple applications.

[0003] To address this, patent CN214927750U discloses a metal composite plate, including an aluminum core layer. The plate is characterized by: a first polymer film on the lower surface of the aluminum core layer, a bottom aluminum layer on the lower surface of the first polymer film, a second polymer film on the upper surface of the aluminum core layer, and a second aluminum layer, an upper polymer film, and a first aluminum layer sequentially arranged from bottom to top on the upper surface of the second polymer film, forming a composite plate. The composite plate has a bending portion, where the first aluminum layer, the upper polymer film, and the second aluminum layer are tightly bonded to each other. This invention, by adding an extra aluminum layer to the surface of the aluminum core layer, improves the overall strength of the metal composite plate through this two-layer aluminum design. More importantly, the added two aluminum layers significantly enhance the bending strength, thus increasing the product's service life.

[0004] The aforementioned metal composite panels have insufficient heat insulation and flame retardant properties during use, which limits their application and makes them difficult to combine and splice, thus failing to meet actual usage requirements. Utility Model Content

[0005] The purpose of this invention is to provide a high-insulation metal composite panel to solve the defects of existing metal composite panels that have insufficient insulation performance and are not convenient for combination use.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high heat insulation metal composite panel, comprising an outer metal plate and an inner lining plate;

[0007] The outer metal plate is provided with an inner lining plate, and the inner lining plate is provided with a reinforcing structure on both sides.

[0008] The reinforcing structure includes heat insulation plates disposed on both sides of the inner lining plate, a reinforcing layer disposed on one side of the heat insulation plate, an adhesive layer disposed on one side of the reinforcing layer, and a flame retardant layer disposed on one side of the adhesive layer;

[0009] The outer metal plate has a combined structure on both sides.

[0010] Preferably, the interior of the heat insulation board is honeycomb-shaped, and the heat insulation board is symmetrically distributed on both sides of the inner lining board.

[0011] Preferably, the reinforcing layer is a glass fiber layer, and the adhesive layer is a hot-press adhesive layer.

[0012] Preferably, the flame-retardant layer is a halogen-free flame-retardant material.

[0013] Preferably, the combined structure includes reinforcing plates evenly disposed on both sides of the outer metal plate and a limiting groove formed on one side of the outer metal plate. A decorative layer is provided on the outer side of the reinforcing plate, and a protrusion is fixed on the side of the outer metal plate away from the limiting groove.

[0014] Preferably, the reinforcing plates are distributed at equal intervals on both sides of the outer metal plate.

[0015] Preferably, the protrusion is disposed inside the limiting groove, and the adjacent outer metal plate forms an engaging structure with the limiting groove through the protrusion.

[0016] The advantages of the high heat insulation metal composite panel provided by this utility model are as follows:

[0017] By setting up a reinforced structure, the heat insulation board on the outer side of the inner lining plate has honeycomb-shaped through holes, which facilitates the storage and insulation of heat passing through the inner metal plate, thereby improving the heat insulation effect. The reinforcing layer and the flame retardant layer are bonded together by a hot-press adhesive layer, thereby strengthening the strength and flame retardant effect of the device, thus achieving the purpose of improving the heat insulation of the plate.

[0018] By setting up a combined structure, adjacent outer metal plates are positioned by a snap-fit ​​structure consisting of protrusions and limiting grooves, making it difficult for the positions of the two sets of outer metal plates to shift. Furthermore, the reinforcing plates that are evenly fixed on both sides of the outer metal plates facilitate the strengthening of the composite plate, thereby achieving the purpose of facilitating the strengthening of the metal composite plate and its combined use.

[0028] In order to improve the performance of the metal composite panel, a reinforcing structure 3 is provided. Heat insulation plates 301 are provided on both sides of the inner lining plate 2 inside the outer metal plate 1. The heat insulation plate 301 has a honeycomb design inside, which facilitates the storage and insulation of heat transferred to the interior. A reinforcing layer 302 and a flame retardant layer 304 are sequentially provided on one side of the heat insulation plate 301 and are bonded together by an adhesive layer 303. The reinforcing layer 302 is made of glass fiber, which increases the overall strength of the metal composite panel, and the flame retardant layer 304 is a halogen-free flame retardant material, which plays a flame retardant role, thereby greatly increasing the practicality of the device.
