[0002] Aluminum composite panels are a common building material that can be used for both exterior and interior decoration.

[0003] Chinese utility model patent with announcement number CN219033864U introduces a fireproof and earthquake-resistant aluminum composite panel, belonging to the field of aluminum composite panel technology. It includes two aluminum panels, end plates are provided on both sides between the two aluminum panels, a polymer material layer is provided between the two end plates, a corrugated plate is provided in the polymer material layer, a flame-retardant plate one is provided between the polymer material layer and the aluminum panels, and a flame-retardant plate two is provided between the flame-retardant plate one and the polymer material layer.

[0005] This application provides another technical solution to this technical problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide fireproof and flame-retardant aluminum composite panels.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: The fire-retardant aluminum composite panel comprises, in sequence, an aluminum layer one, a support layer and an aluminum layer two. The edge of the aluminum layer one has vent holes. The support layer includes a main body and an elastic part extending from the edge. The elastic part is arranged in a ring structure. A flow port is formed in the center of the elastic part. The main body is provided with several clearance ports at intervals. A flame-retardant layer that releases flame-retardant gas when heated is provided in the clearance ports. The clearance ports and the flow ports are connected.

[0008] The present invention is further configured such that: the elastic part is provided with a blocking member for blocking the flow port, and the blocking member and the elastic part are movably connected.

[0009] The present invention is further configured such that: the elastic part includes two blocking edges one and two blocking edges two, which are symmetrically arranged between the two blocking edges one and between the two blocking edges two.

[0010] The present invention is further configured such that: an movable gap is formed between adjacent shielding edge one and shielding edge two, and the shielding member includes an extension protrusion formed on one of the shielding edges two, the extension protrusion abutting against the other shielding edge two and the two shielding edges one, and the two adjacent extension protrusions on the two aluminum-plastic plates respectively contact each other.

[0011] The present invention is further configured such that: the second blocking edge of the unformed extension protrusion and one of the two blocking edges are each formed with an inclined surface, and the extension protrusion is formed with an inclined surface two with the same inclination angle at the corresponding inclined surface.

[0012] The present invention is further configured such that the first and second shielding edges are made of elastic silicone rubber.

[0013] In summary, this utility model has the following beneficial effects: When a fire occurs, the aluminum composite panel is heated, and the flame-retardant layer releases flame-retardant gas. The gas enters the flow port. When the flame-retardant gas in the flow port accumulates to a certain level, the gas pressure in the flow port increases, which pushes the extension protrusion to rotate. The extension protrusion rotates towards the adjacent extension protrusion. The adjacent extension protrusion will squeeze and deform the blocking edge one and blocking edge two, thereby reducing the degree of obstruction of the flow port by the extension protrusion, making it easier for the flame-retardant gas to flow out to the outside, and increasing the flame-retardant effect.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] like Figure 1 and Figure 2 As shown, this application provides a fire-retardant aluminum composite panel, which includes an aluminum layer 1, a support layer, and an aluminum layer 2. The aluminum layer 1 and aluminum layer 2 are fixed on both sides of the support layer. In this embodiment, the aluminum layer 1, the support layer, and the aluminum layer 2 are all square in structure. The aluminum composite panel has four sides. The support layer includes a main body 3 and elastic parts extending from the edges. In this embodiment, four elastic parts are provided, each corresponding to one of the four sides of the aluminum composite panel. The elastic parts are annular in structure, with a flow port formed at the center of each elastic part. The two ends of the flow port open towards the main body 3 and away from the main body 3, respectively. 3. The elastic part includes two shielding edges 4 and two shielding edges 5. The two shielding edges 4 and the two shielding edges 5 are symmetrically arranged. The two shielding edges 5 are connected to aluminum layer 1 and aluminum layer 1 respectively. The adjacent shielding edges 4 and shielding edges 5 are not integrally formed, which makes it possible to form a movable gap between the adjacent shielding edges 4 and shielding edges 5. The adjacent shielding edges 4 and shielding edges 5 can move relative to each other to a certain extent. The shielding edges 4 and shielding edges 5 are made of elastic silicone rubber. Elastic silicone rubber has a flame retardant effect, which can improve the flame retardant effect of aluminum composite panel.

[0018] like Figure 1 , Figure 2 as well as Figure 3 As shown, the edge of aluminum layer 1 has vent holes 6. When the aluminum composite panel is laid on the wall, aluminum layer 2 is fixed to the wall, aluminum layer 1 faces outward, and the vent holes 6 are located between two adjacent aluminum composite panels. The main body 3 is provided with several clearance openings 7, which are connected to the flow opening. A flame-retardant layer 8 is provided in the clearance opening 7. The flame-retardant layer 8 is made of halophosphate. When the flame-retardant layer 8 is heated to a certain degree, it will release flame-retardant gas. The flame-retardant gas will enter the flow opening from the clearance opening 7 and then flow out to the outside through the vent holes 6. In case of fire, the flame-retardant gas will reduce the oxygen near the flame of the aluminum composite panel, inhibit combustion, reduce the probability of the aluminum composite panel burning, and play a flame-retardant role.

[0019] like Figure 2 and Figure 3 As shown, the elastic part is provided with a shielding member, which includes an extension protrusion 9 formed on one of the shielding edges 5. In this embodiment, the extension protrusion 9 is located on the shielding edge 5 near the aluminum layer 2. In the initial state, the extension protrusion 9 abuts against the other shielding edge 2 5 and the two shielding edges 4, thereby shielding the flow opening. When the aluminum composite panel is laid on the wall, the two adjacent extension protrusions 9 on the two aluminum composite panels respectively come into contact with each other. The extension protrusion 9 can reduce the air in contact with the flame retardant layer 8, reduce the probability of the halophosphate ester coming into contact with water vapor in the air, and extend the life of the flame retardant layer 8 to produce the flame retardant effect.

[0020] like Figure 2 As shown, the unformed extended protrusion 9 has an inclined surface 1 at the second shielding edge 5 and the two shielding edges 4. The extended protrusion 9 has an inclined surface 2 with the same inclination angle at the corresponding inclined surface 1. When a fire occurs, the aluminum composite panel is heated, and the flame-retardant layer 8 releases flame-retardant gas. The gas will enter the flow port. When the flame-retardant gas in the flow port accumulates to a certain level, the gas pressure in the flow port increases, which will push the extended protrusion 9 to rotate. The extended protrusion 9 will rotate towards the adjacent extended protrusion 9. The adjacent extended protrusion 9 will squeeze the shielding edge 4 and the second shielding edge 5. With the guidance of the inclined surfaces 1 and 2, they will deform, which can reduce the degree of obstruction of the flow port by the extended protrusion 9, making it easier for the flame-retardant gas to flow out to the outside and increasing the flame-retardant effect.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
