Description

Technical Field

[0001] This utility model relates to the field of aluminum-plastic composite panel technology, and in particular to a fireproof aluminum-plastic composite panel. Background Technology

[0002] Aluminum composite panels possess unique properties and have a wide range of applications: they can be used for building exterior walls, curtain wall panels, renovation of old buildings, interior wall and ceiling decoration, advertising signs, display stands, and cleanroom dust control projects. However, with the increasing prevalence of household appliances, the wiring layout within homes has become more complex, leading to a rise in fire rates and increasingly stringent fire safety requirements for housing. Aluminum composite panels often struggle to meet the fire safety demands of modern decoration. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a fireproof aluminum-plastic composite panel, which more accurately solves the problems described above.

[0004] This utility model is achieved through the following technical solution: This utility model proposes a fireproof aluminum-plastic composite panel, including an aluminum-plastic composite panel body. The aluminum-plastic composite panel body includes a core material main layer, a first transition layer, a first outer surface layer, a second transition layer, and a second outer surface layer. The first transition layer is provided on the surface of the core material main layer, and the first outer surface layer is provided on the surface of the first transition layer. The second transition layer is provided on the back side of the core material main layer, and the second outer surface layer is provided on the back side of the second transition layer. The core material main layer uses an aluminum honeycomb layer as a base layer. The upper layer of the honeycomb cells in the aluminum honeycomb layer is filled with a fireproof layer, and the lower layer of the honeycomb cells is filled with a heat insulation layer. A conical aluminum partition is provided in the middle of the honeycomb cells of the core material main layer, and the conical aluminum partition separates the fireproof layer and the heat insulation layer.

[0005] Furthermore, the fireproof layer is a phosphorus-nitrogen expanded powder filler block, and the phosphorus-nitrogen expanded powder filler block contains 25-35% aerogel particles.

[0006] Furthermore, the insulation layer is a modified aluminum hydroxide / magnesium gel mixed filler block, and the second transition layer, the second outer surface layer, and each honeycomb hole position corresponding to the core material main layer are provided with pores.

[0007] Furthermore, both the first transition layer and the second transition layer are based on a flame-retardant epoxy resin layer, and a carbon fiber mesh layer is embedded within the flame-retardant epoxy resin layer.

[0008] Furthermore, the upper and lower surfaces of the core material main layer are provided with several trapezoidal channels arranged at equal intervals, and the first outer surface layer and the second outer surface layer are stamped with anti-cracking strips corresponding to the trapezoidal channels of the core material main layer. The anti-cracking strips are engaged in the corresponding trapezoidal channels.

[0009] Furthermore, both the first and second outer surfaces are anodic aluminum oxide plates, and both surfaces are coated with a nano-ceramic fireproof coating.

[0010] The beneficial effects of this utility model are: 1. In this utility model, a fireproof layer is filled in the upper layer of the honeycomb holes of the core material main layer, and a heat insulation layer is filled in the lower layer of the honeycomb holes. When the fireproof layer is exposed to high temperature, it expands to form a dense carbon layer, which is used to isolate oxygen and effectively play a fireproof role. The heat insulation layer decomposes and absorbs heat and releases water vapor at high temperature, which effectively inhibits combustion and greatly improves the fireproof performance. 2. This utility model has several equally spaced trapezoidal grooves on the upper and lower surfaces of the core material main layer. The first outer surface layer and the second outer surface layer are stamped with anti-cracking strips corresponding to the trapezoidal grooves of the core material main layer. The anti-cracking strips are engaged in the corresponding trapezoidal grooves, which effectively prevents interlayer cracking of the aluminum-plastic composite panel when the core material main layer is subjected to high temperature.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0014] A fireproof aluminum-plastic composite panel includes an aluminum-plastic composite panel body 1. The aluminum-plastic composite panel body 1 includes a core material main layer 101, a first transition layer 102, a first outer surface layer 103, a second transition layer 1021, and a second outer surface layer 1031. The first transition layer 102 is provided on the surface of the core material main layer 101, and the first outer surface layer 103 is provided on the surface of the first transition layer 102. The second transition layer 1021 is provided on the back side of the core material main layer 101, and the second outer surface layer 1031 is provided on the back side of the second transition layer 1021. The core material main layer 101 uses an aluminum honeycomb layer as a base layer to achieve lightweighting.

[0015] The upper layer of the aluminum honeycomb layer is filled with a fireproof layer 1012, and the lower layer is filled with a heat insulation layer 1013. The fireproof layer 1012 is a phosphorus-nitrogen expanded powder filler block. The phosphorus-nitrogen expanded powder filler block uses phosphorus-nitrogen-based expanded flame retardant as a base material. When exposed to high temperature, it expands to form a dense carbon layer, which is used to isolate oxygen and effectively play a fireproof role. In addition, the phosphorus-nitrogen expanded powder filler block contains 25-35% aerogel particles, which are used to play a heat insulation role.

[0016] The insulation layer 1013 is a modified aluminum hydroxide / magnesium gel mixed filler block. The modified aluminum hydroxide / magnesium gel decomposes at high temperature, absorbs heat and releases water vapor, effectively inhibiting combustion. The second transition layer 1021, the second outer surface layer 1031 and each honeycomb hole position corresponding to the core material main layer 101 are provided with pores 104 to discharge the water vapor released by the high temperature decomposition of the modified aluminum hydroxide / magnesium gel.

[0017] The honeycomb pores of the core material main layer 101 are provided with a conical aluminum partition 1011. The conical aluminum partition 1011 separates the fireproof layer 1012 and the heat insulation layer 1013. The conical aluminum partition 1011 can deform when the fireproof layer 1012 expands, which can reserve expansion space and prevent the aluminum-plastic composite panel body 1 from bulging and cracking. At the same time, the conical aluminum partition 1011 can fully contact the heat to the heat insulation layer 1013 and accelerate the reaction.

[0018] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages: In this utility model, the upper layer of the honeycomb holes in the core material main layer 101 is filled with a fireproof layer 1012, and the lower layer of the honeycomb holes is filled with a heat insulation layer 1013. When the fireproof layer 1012 is exposed to high temperature, it expands to form a dense carbon layer, which is used to isolate oxygen and effectively play a fireproof role. The heat insulation layer 1013 decomposes and absorbs heat at high temperature and releases water vapor, which effectively inhibits combustion and greatly improves the fireproof performance. Example 2

[0019] Both the first transition layer 102 and the second transition layer 1021 are based on flame-retardant epoxy resin layers, and carbon fiber mesh layers are embedded in the flame-retardant epoxy resin layers. The thermal expansion coefficient of the carbon fiber mesh layers matches that of the aluminum plate, effectively preventing bulging of the aluminum-plastic composite panel body 1.

[0020] The upper and lower surfaces of the core material main layer 101 are provided with several equally spaced trapezoidal channels 1014. The first outer surface layer 103 and the second outer surface layer 1031 are stamped with anti-cracking strips 1032 corresponding to the positions of the trapezoidal channels 1014 provided in the core material main layer 101. The anti-cracking strips 1032 are engaged in the corresponding trapezoidal channels 1014, which effectively prevents the interlayer cracking of the aluminum-plastic composite panel body 1 when the core material main layer 101 is subjected to high temperature.

[0021] Both the first outer layer 103 and the second outer layer 1031 are coated with a nano-ceramic fireproof coating to improve the fire resistance of the aluminum-plastic composite panel body 1. Both the first outer layer 103 and the second outer layer 1031 are anodized aluminum plates to enhance the adhesion of the nano-ceramic fireproof coating to the surfaces of the first outer layer 103 and the second outer layer 1031.

[0022] The technical solutions in the above embodiments of this application have at least the following technical effects or advantages: The upper and lower surfaces of the core material main layer 101 of this utility model are provided with a number of equally spaced trapezoidal channels 1014, and the first outer surface layer 103 and the second outer surface layer 1031 are stamped with anti-cracking strips 1032 at the positions of the trapezoidal channels 1014 provided in the core material main layer 101. The anti-cracking strips 1032 are engaged in the corresponding trapezoidal channels 1014, which effectively prevents the interlayer cracking of the aluminum-plastic composite panel body 1 when the core material main layer 101 is subjected to high temperature.

[0023] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
