It is a new type of building decoration material.

[0003] For example, Chinese patent CN202106618U discloses a fireproof aluminum-plastic panel, which includes a core layer, a decorative aluminum plate layer and a base aluminum plate layer. The core layer adopts a three-layer structure, which is composed of an upper and lower low-pressure polyethylene layer sandwiching a flame retardant material layer. The entire fireproof aluminum-plastic panel is composed of a five-layer structure consisting of a decorative aluminum plate layer, a low-pressure polyethylene layer, a flame retardant material layer, a low-pressure polyethylene layer, and a base aluminum plate layer from top to bottom.

[0004] However, in the prior art, after the aluminum-plastic panel is installed, it plays a role in fire prevention, and the fire-retardant coating or fire-retardant material on the surface will be oxidized and corroded due to long-term use, thereby causing the fire-retardant effect of the fire-retardant material to gradually decrease. In addition, the commonly used aluminum-plastic panel has a simple structure, so its impact resistance and bending resistance are also poor, which makes it easy to bend. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the surface fire-retardant coating or fire-retardant material in the prior art will be oxidized and corroded due to long-term use, thereby causing the fire-retardant effect of the fire-retardant material to gradually decrease, and the problem that it is easy to bend due to impact, and to propose a fire-retardant aluminum-plastic panel for construction.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a fireproof aluminum-plastic panel for construction, comprising a substrate, a PE plastic core material is fixedly connected to the top of the substrate, an anti-corrosion film is compositely connected to the outer surface of the PE plastic core material, a gypsum board is fixedly connected to the bottom of the substrate, both sides of the gypsum board are compositely connected to the anti-corrosion film, and the inner surface of the anti-corrosion film is compositely connected to the outer surface of the substrate.

[0007] Preferably, a mounting groove is provided at the bottom of the base plate, and a reinforcing steel plate is provided inside the mounting groove.

[0008] Preferably, both sides of the reinforcing steel plate are fixedly connected with a foamed polyurethane layer.

[0009] Preferably, the reinforcing steel plate and the foamed polyurethane layer are both compositely connected to the base plate.

[0010] Preferably, a chlorinated rubber coating layer is coated on the bottom of the gypsum board.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. In the utility model, the anti-corrosion film can play an anti-corrosion role to avoid rust, thereby protecting the internal materials and preventing the internal fireproof materials from failing. In addition, the use of gypsum board can also have a good sound insulation effect, making the overall weight lighter.

[0013] 2. In the utility model, the reinforcing steel plate can be connected to the base plate through the installation groove, which can further enhance the overall impact resistance and bending resistance, making the overall plate tougher, and using the foamed polyurethane layer to fill the gap between the reinforcing steel plate and the base plate, which can also improve the firmness of the bonding between the base plate and the reinforcing steel plate.

[0018] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0020] Embodiment 1

[0021] like Figure 1-3As shown, the utility model provides a fireproof aluminum-plastic panel for construction, including a substrate 1, a PE plastic core material 2 is fixedly connected to the top of the substrate 1, an anti-corrosion film 4 is compositely connected to the outer surface of the PE plastic core material 2, a gypsum board 3 is fixedly connected to the bottom of the substrate 1, both sides of the gypsum board 3 are compositely connected to the anti-corrosion film 4, and the inner surface of the anti-corrosion film 4 is compositely connected to the outer surface of the substrate 1.

[0022] The specific settings and functions of this embodiment are described in detail below. During long-term use, the anti-corrosion film 4 can play an anti-corrosion role to avoid rust, thereby protecting the internal materials to prevent the fireproof effect from being reduced or even failing due to corrosion due to long-term use. The gypsum board 3 also has good impact resistance, which makes the overall toughness stronger. The gypsum board 3 is light and will not make the overall weight heavier, making the installation more troublesome. In addition, the gypsum board 3 also has a sound insulation effect.

[0023] Embodiment 2

[0024] like Figure 1-3 As shown, a mounting groove 8 is provided at the bottom of the base plate 1, and a reinforcing steel plate 5 is provided inside the mounting groove 8. Both sides of the reinforcing steel plate 5 are fixedly connected with a foamed polyurethane layer 7. The reinforcing steel plate 5 and the foamed polyurethane layer 7 are compositely connected to the base plate 1. A chlorinated rubber coating layer 6 is coated on the bottom of the gypsum board 3.

[0025] The effect achieved by the whole embodiment is that the reinforcing steel plate 5 is installed inside the installation groove 8 at the bottom of the base plate 1. Therefore, the use of multiple installation grooves 8 to install multiple reinforcing steel plates 5 can improve the overall bending resistance and impact resistance, thereby making the whole more solid, and inside the reinforcing steel plate 5, both sides are provided with foamed polyurethane layers 7, which can not only fill the gap between the reinforcing steel plate 5 and the base plate 1, but also improve the firmness of the bonding between the base plate 1 and the reinforcing steel plate 5.

[0026] The method of use and working principle of this device: Under normal circumstances, multiple plates will be assembled together. During long-term use, the anti-corrosion film 4 can play an anti-corrosion role to avoid rust, thereby protecting the internal materials to prevent the fireproof effect from being reduced or even failing due to corrosion caused by long-term use.

[0027] When encountering fire, the anticorrosive film 4 will be damaged, and the top or bottom of the whole will be affected by the fire. Therefore, the PE plastic core material 2 can block the fire from above and prevent the fire from spreading. Then, the chlorinated rubber coating layer 6 can block the fire from below.

[0028] Next, the reinforcing steel plate 5 can improve the overall bending resistance and impact resistance, thereby making the overall structure more solid. The gypsum board 3 also has good impact resistance, making the overall toughness stronger, and the gypsum board 3 is light, so that the gypsum board 3 can be used to enhance the overall impact resistance and sound insulation effect without making the overall structure heavier.

[0029] Finally, when the PE plastic core material 2 and the chlorinated rubber coating layer 6 are used in buildings, they can not only play a flame retardant role but also reduce the harm of fire to other materials.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
