Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of decorative plates, and more specifically, to a flame retardant aluminum-plastic plate. Background Art
[0002] Aluminum-plastic panel is a composite decorative panel made of metal and plastic materials and is widely used in decoration.
[0003] In construction, fire prevention is an important measure. The surface of the aluminum-plastic panel is made of aluminum alloy, which is not easy to burn, but the plastic material in the center will burn due to high temperature.
[0004] At present, flame retardant plastic materials are selected to make the middle layer of the aluminum-plastic panel, so as to improve the flame retardant effect of the aluminum-plastic panel.
[0005] This application provides another technical solution to this technical problem. Utility Model Content
[0006] In view of the deficiencies in the prior art, the utility model aims to provide a flame retardant aluminum-plastic panel.
[0007] The above technical objectives of the utility model are achieved through the following technical solutions:
[0008] A flame retardant aluminum-plastic panel comprises, from outside to inside, an aluminum alloy plate and a plastic layer, and also comprises a limit strip. The plastic layer is provided with an annular protrusion extending from the edge of the aluminum alloy plate. The annular protrusion and the limit strip are detachably connected. The limit strip is provided with an elastic sheet pressing against the edge of the aluminum alloy plate. A flow space is formed between the elastic sheet and the plastic layer. A flame retardant layer which releases flame retardant gas when heated is arranged in the plastic layer.
[0009] The utility model is further configured as follows: a clearance opening is formed on the side of the plastic layer facing the aluminum alloy plate, and the flame retardant layer is located in the clearance opening and in contact with the aluminum alloy plate.
[0010] The utility model is further configured as follows: a rubber pad is fixedly connected to one side of the elastic sheet facing the aluminum alloy plate.
[0011] The utility model is further configured as follows: the limit strip is formed with a clamping groove, the annular convex part is formed with a clamping convex, and the clamping convex and the clamping groove are clamped with each other.
[0012] The utility model is further configured as follows: the clamping convex is formed with a guiding cambered surface.
[0013] The utility model is further configured as follows: the plastic layer is made of polyethylene material.
[0014] In summary, the utility model has the following beneficial effects:
[0015] When the aluminum-plastic panel is heated, the flame retardant layer will directly receive the heat of the aluminum alloy plate due to the contact with the aluminum alloy plate. The flame retardant layer will generate flame-retardant gas when heated, and the flame-retardant gas will enter the flow space. When the air pressure in the flow space is higher than the elastic force of the elastic sheet, the flame-retardant gas will be released to the outside, reducing the oxygen at the flame, inhibiting combustion, and achieving a flame retardant effect.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments.
[0020] like Figure 1 and Figure 2 As shown, the present application provides a flame retardant aluminum-plastic panel, which includes an aluminum alloy plate 1, a plastic layer 2 and a limit strip 3 from the outside to the inside. The plastic layer 2 is made of polyethylene material. Polyethylene has the effect of inhibiting combustion, so that when the aluminum-plastic panel is overheated, the plastic layer 2 is not easy to burn due to reaching the combustion temperature, and the limit strip 3 can be used to connect and fix two adjacent aluminum-plastic panels.
[0021] like Figure 1 and Figure 2As shown, the plastic layer 2 is provided with an annular protrusion 4 extending from the edge of the aluminum alloy plate 1, wherein the limiting strip 3 is formed with a card slot 5, and each limiting strip 3 has two card slots 5. A card protrusion 6 is formed at the annular protrusion 4, and the card protrusion 6 is formed with a guide arc surface. When installing, the two aluminum-plastic plates are brought close to and abutted, and then the limiting strip 3 is placed between the two aluminum-plastic plates, and the limiting strip 3 is pressed strongly. The card protrusion 6 is pressed by the opening edge of the card slot 5 and deformed. The card protrusion 6 will slide into the card slot 5 along the guide arc surface, and the card protrusion 6 will be inserted into the card slot 5. After completely sliding into the slot 5, the latch 6 is reset, and finally the latch 6 and the slot 5 are latched, thereby realizing the connection between the two aluminum-plastic panels. The limit strip 3 is extended with an elastic sheet 10 that presses against the edge of the aluminum alloy plate 1. The elastic sheet 10 will shield the two aluminum-plastic panels to ensure aesthetics and connection stability. A rubber pad 11 is fixedly connected to the side of the elastic sheet 10 facing the aluminum alloy plate 1. The rubber pad 11 can block dust and reduce the dust from entering between the elastic sheet 10 and the aluminum alloy plate 1.
[0022] like Figure 1 and Figure 2 As shown, a flow space 9 is formed between the elastic sheet 10 and the plastic layer 2, wherein a clearance opening 7 is formed on the side of the plastic layer 2 facing the aluminum alloy plate 1, and a flame retardant layer 8 is arranged in the plastic layer 2, and the flame retardant layer 8 is located in the clearance opening 7 and in contact with the aluminum alloy plate 1. In this embodiment, the flame retardant layer 8 is made of halogenated phosphate. When the aluminum-plastic plate is heated, the flame retardant layer 8 will directly receive the heat of the aluminum alloy plate 1 due to contact with the aluminum alloy plate 1. The flame retardant layer 8 is heated to generate a flame retardant gas, and the flame retardant gas enters the flow space 9. When the air pressure in the flow space 9 is higher than the elastic force of the elastic sheet 10, the flame retardant gas is released to the outside, thereby reducing the oxygen at the flame, suppressing combustion, and achieving a flame retardant effect.
[0023] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
