[0002] Aluminum composite panel (ACP) is a lightweight, high-strength building decoration material made of a metallic aluminum layer and a non-metallic core material bonded together with a polymer adhesive.

[0003] In the prior art, such as the aluminum composite panel with application number 201820715937.0, the structure is simple and easy to manufacture. It can not only complete the construction of exhibition halls, but also effectively reduce the unit weight of the panels and ensure the decorative effect of the exhibition hall. This utility model is widely applicable to the building decoration industry.

[0004] However, in the current technology, aluminum composite panels have reached the flame-retardant standard through flame retardants, but when used in high-rise buildings and shopping malls, there is still a risk of combustion. At the same time, as a building material, aluminum composite panels have high surface hardness and are easily affected by external factors (such as rain and knocking), which can generate noise and cause discomfort.

This utility model sets up a sound-absorbing and flame-retardant mechanism, and sets up a nano flame-retardant coating between the flame-retardant layer and the outer layer, so that a transparent protective film can be formed on the surface of the flame-retardant layer. The nano flame-retardant layer uses silica-based nanomaterials to achieve hydrophobicity, oleophobicity, acid and alkali corrosion resistance and self-cleaning function, while improving flame-retardant performance.

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] To address the problems existing in the prior art, this embodiment provides the following technical solution: a sound-absorbing and flame-retardant aluminum composite panel. The panel comprises an aluminum composite panel body 1, which is composed of a multi-layer composite structure. A flame-retardant layer 12 and a sound-absorbing layer 13 are disposed in the middle of the aluminum composite panel body 1. The flame-retardant layer 12 enhances the overall flame-retardant effect of the aluminum composite panel body 1, and the sound-absorbing layer 13 enhances the overall sound-absorbing effect of the aluminum composite panel body 1. Additionally, protrusions 3 and grooves 4 are provided between each layer, effectively strengthening the bonding strength between each layer.

[0026] like Figure 2 , Figure 3 and Figure 4 As shown, an aluminum composite panel body 1 is provided. The aluminum composite panel body 1 is composed of an outer layer 11, a flame retardant layer 12, a sound-absorbing layer 13 and a bottom layer 14. The outer layer 11 is provided on the top of the aluminum composite panel body 1 and is a PVDF coated aluminum plate. The flame retardant layer 12 and the sound-absorbing layer 13 are provided in the middle of the aluminum composite panel body 1, and the bottom layer 14 is provided at the bottom of the aluminum composite panel body 1.

[0027] The flame-retardant layer 12 and the sound-absorbing layer 13 constitute a sound-absorbing and flame-retardant mechanism. A flame-retardant coating 121 is bonded to the upper side of the flame-retardant layer 12. The flame-retardant coating 121 forms a transparent protective film on the upper surface of the flame-retardant layer 12. At the same time, silica-based nanomaterials are used to achieve hydrophobic and oleophobic properties, acid and alkali corrosion resistance, and self-cleaning functions. In addition, ATH is incorporated into the interior of the flame-retardant layer 12 as a flame retardant. When heated, ATH decomposes, absorbs heat, and releases water vapor, diluting flammable gases and generating an alumina barrier layer, which can effectively inhibit the spread of flames.

[0028] A sound-absorbing layer 13 is provided below the flame-retardant layer 12, and a damping layer 131 is provided on top of the sound-absorbing layer 13. A sound-absorbing layer 132 is bonded to the lower side of the damping layer 131, and a radiation layer 133 is bonded to the lower side of the sound-absorbing layer 132. The sound-absorbing layer 13 is composed of three layers: the damping layer 131, the sound-absorbing layer 132, and the radiation layer 133. The damping layer 131, made of a polymer such as butyl rubber, can reduce structural vibration noise with a vibration reduction efficiency of over 60%. The sound-absorbing layer 132 is made of rock wool or glass wool with a density of 80-120 kg / m³. 3 For mid-to-high frequency frequencies above 500Hz with a sound absorption coefficient ≥0.8, the radiating layer 133 can block the penetration of low-frequency sound waves by setting aluminum foil or perforated aluminum plates, increasing the sound insulation by 5-8 decibels;

[0029] In addition, the damping layer 131, the sound-absorbing layer 132 and the radiating layer 133 are all provided with honeycomb cores 134 in an array. The honeycomb cores 134 are set with a hexagonal structure, which can absorb sound waves of specific frequency bands through the Helmholtz resonance principle and improve the sound absorption coefficient. Secondly, the honeycomb cores 134 are filled with polyurethane foam 135 with a porosity of >95%, which can further reduce high-frequency noise.

[0030] The damping layer 131, sound-absorbing layer 132, and radiation layer 133 are configured with different density gradients; for example, the damping layer 131 is set to 1.2 g / cm³. 3 The sound-absorbing layer 132 is set to 0.1g / cm². 3 And the radiation layer 133 was set to 2.7 g / cm³. 3 It can achieve wideband noise attenuation;

[0031] Meanwhile, protrusions 3 are provided at equal distances on the upper end of the flame-retardant layer 12 and the upper and lower sides of the outer surface of the sound-absorbing layer 13, and grooves 4 are provided at equal distances on the lower end of the flame-retardant layer 12, the lower end of the outer layer 11, and the upper end of the bottom layer 14.

[0032] The protrusion 3 at the upper end of the flame retardant layer 12 engages with the groove 4 inside the lower end of the outer layer 11, the groove 4 inside the lower end of the flame retardant layer 12 engages with the protrusion 3 on the upper side of the sound-absorbing layer 13, and the protrusion 3 at the lower end of the sound-absorbing layer 13 engages with the groove 4 inside the upper end of the bottom layer 14.

[0033] The protrusions 3 and grooves 4 enable each layer of adhesive to interlock with each other, effectively strengthening the bonding strength between each layer. Furthermore, the adhesives between each layer are flame-retardant adhesives, which effectively enhance the flame retardancy of the overall aluminum composite panel body 1.

[0034] like Figure 1 and Figure 4 As shown, a splicing component 2 is bonded to the outside of the aluminum composite panel body 1. The splicing component 2 includes a side frame 21 that is set around the outside of the aluminum composite panel body 1. A splicing groove 22 is set at the left end of the outside of the side frame 21, and a splicing block 23 is set at the right end of the side frame 21. At the same time, positioning holes 24 are symmetrically opened in the front and back of the splicing groove 22 and the splicing block 23.

[0035] When installing aluminum composite panels, multiple panels need to be spliced ​​together. The splicing block 23 on the right side of the splicing component 2 on the outside of the aluminum composite panel can be aligned with the splicing groove 22 on the left side of another aluminum composite panel and inserted. When the splicing block 23 is inserted into the splicing groove 22, the positioning holes 24 inside the two panels will fit together. Bolts can then be inserted into the positioning holes 24 for positioning. At this time, the two spliced ​​aluminum composite panel bodies 1 can be firmly fixed. Through this operation, multiple aluminum composite panel bodies 1 can be spliced ​​together.

[0036] The working principle of this sound-absorbing and flame-retardant aluminum composite panel is as follows: The aluminum composite panel body 1 is composed of an outer layer 11, a flame-retardant layer 12, a sound-absorbing layer 13, and a bottom layer 14. The flame-retardant layer 12 and the sound-absorbing layer 13 are located in the middle of the aluminum composite panel body 1. The flame-retardant layer 12 has a flame-retardant coating 121 on its upper side and incorporates ATH internally, which can improve the flame retardancy of the aluminum composite panel body 1. At the same time, the sound-absorbing layer 13 is composed of three layers of damping layer 131 of different densities, a sound-absorbing layer 132, and a honeycomb core 134. Furthermore, each of the three layers contains... The honeycomb core 134 is filled with polyurethane foam 135, which can effectively improve the sound absorption of the aluminum composite panel body 1. At the same time, grooves 4 are equally spaced in the lower end of the outer layer 11, the lower end of the flame retardant layer 12, and the upper end of the bottom layer 14. Protrusions 3 are provided on the upper end of the flame retardant layer 12 and the upper and lower sides of the outer surface of the sound absorption layer 13. The protrusions 3 and the grooves 4 can be interlocked and connected. The flame retardant adhesive can strengthen the bonding between each layer.

[0037] Secondly, splicing components 2 are set on the outside of the aluminum composite panel body 1. The side frame 21 is set around the outside of the aluminum composite panel body 1. At the same time, a splicing groove 22 is set on the left side of the side frame 21 and a splicing block 23 is set on the right side. The splicing block 23 and the splicing groove 22 can be connected and fixed. This setting can splice multiple aluminum composite panels 1 together.
