[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0022] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] Example

[0024] like Figures 1-6 As shown, a heat-insulating and noise-reducing metal composite wall panel includes: a composite wall panel body 1, an outer metal shell 2 installed on the outside of the composite wall panel body 1, an inner metal shell 3 installed on the inside of the composite wall panel body 1, and a heat-insulating and noise-reducing component disposed inside the composite wall panel body 1. The heat-insulating and noise-reducing component includes: a foam layer 8, a partition layer 801, and a foam structural block 802.

[0025] The composite wall panel body 1 has multiple protrusions 4 on both sides of its outer end, and multiple concave grooves 5 on the inner sides of both the outer metal shell 2 and the inner metal shell 3 that fit with the protrusions 4. When using the composite wall panel body 1, epoxy resin adhesive is applied to the inner sides of the outer metal shell 2 and the inner metal shell 3, as well as to both sides of the outer end of the composite wall panel body 1. Then, the outer metal shell 2 and the inner metal shell 3 are respectively pasted and fixed to both sides of the outer end of the composite wall panel body 1, and pressed tightly by a machine, so that the outer metal shell 2 and the inner metal shell 3 are firmly attached to the composite wall panel body 1. The main body 1 of the composite wall panel is firmly bonded together, providing a hard outer shell to protect the main body 1 of the composite wall panel and preventing deformation and damage after being hit. When the outer metal shell 2 and the inner metal shell 3 are attached to the main body 1 of the composite wall panel, the concave grooves 5 on the inner side of the outer metal shell 2 and the inner metal shell 3 fit together with the protrusions 4 on both sides of the outer end of the main body 1 of the composite wall panel, which can increase the interlocking force between the outer metal shell 2 and the inner metal shell 3 and the main body 1 of the composite wall panel, and prevent the outer metal shell 2 and the inner metal shell 3 from easily falling off.

[0026] The composite wall panel body 1 has a fixing groove 6 on one side of its outer end and a limiting block 7 on the other side of its outer end. When multiple composite wall panel bodies 1 need to be spliced ​​together during use, since one end of the composite wall panel body 1 has a fixing groove 6 and the other end has a limiting block 7, the limiting block 7 of one composite wall panel body 1 can be inserted into the fixing groove 6 of another composite wall panel body 1 and fixed with bolts, so that multiple composite wall panel bodies 1 can be quickly and stably assembled and used.

[0027] The composite wall panel body 1 has a foam layer 8 in the middle, which is made of high-density polyurethane foam. The foam layer 8 has three partitions 801 inside, and multiple independent sealed foam structure blocks 802 inside the three partitions 801. During use, the foam layer 8, made of high-density polyurethane foam, has independent sealed foam structure blocks 802 inside. When in use, it can block heat and noise through its own independent sealed foam structure blocks 802. The composite wall panel body 1 can achieve the purpose of heat insulation, heat preservation, sound reduction and noise reduction through the foam layer 8. Moreover, the porous foam structure blocks 802 have good air permeability, which can prevent moisture and mold damage, and extend the service life of the foam layer 8. This solves the problem that existing heat insulation cotton and sound insulation cotton are easily damaged after being exposed to moisture, resulting in poor heat insulation and noise reduction effect of metal composite wall panels.

[0028] Among them, the foam layer 8 has a buffer layer 803 on both sides of the outer end. The buffer layer 803 is made of foamed polyethylene material. When the foam layer 8 is in use, the buffer layer 803 is set on both sides of the outer end of the foam layer 8. The buffer layer 803 has a buffering effect, so that the foam layer 8 has a buffer space, effectively protecting the stability of the foam layer 8 during use.

[0029] The composite wall panel body 1 has flame-retardant layers 804 on both sides inside, and fire-retardant coatings 805 on the outside of the flame-retardant layers 804. When the composite wall panel body 1 is in use, the flame-retardant layers 804 and fire-retardant coatings 805 on both sides inside the composite wall panel body 1 effectively prevent damage to the internal structural layers of the composite wall panel body 1 caused by external high temperature or combustion. The fire-retardant coating 805 is made of inorganic silicate (mainly potassium silicate) as the main film-forming substance, and is refined with high-performance pigments, fillers and special additives. The paint film of this coating has inorganic properties, is fire-resistant and non-combustible, and does not burn, support combustion, produce smoke or emit toxic gases even when exposed to high temperature.

[0030] Among them, the foam layer 8 has reinforcing ribs 9 on both sides of its outer end. The reinforcing ribs 9 are in a cross structure. During the use of the composite wall panel body 1, the addition of reinforcing ribs 9 on both sides of the outer end of the foam layer 8 can improve the overall structural strength of the composite wall panel body 1, ensure that the composite wall panel body 1 has good stress resistance, and avoid damage to the foam layer 8 inside the composite wall panel body 1.

[0031] Working principle:

[0032] When using the composite wall panel body 1, epoxy resin adhesive is applied to the inner sides of the outer metal shell 2 and the inner metal shell 3, as well as to both sides of the outer end of the composite wall panel body 1. Then, the outer metal shell 2 and the inner metal shell 3 are respectively pasted and fixed to both sides of the outer end of the composite wall panel body 1 and pressed and tightened by machine, so that the outer metal shell 2 and the inner metal shell 3 are firmly bonded to the composite wall panel body 1, providing a hard outer shell protection for the composite wall panel body 1 and preventing deformation and damage after the composite wall panel body 1 is impacted. When the outer metal shell 2 and the inner metal shell 3 are attached to the composite wall panel body 1, the concave grooves 5 on the inner sides of the outer metal shell 2 and the inner metal shell 3 just match the protrusions 4 on both sides of the outer end of the composite wall panel body 1, which can increase the interlocking force between the outer metal shell 2 and the inner metal shell 3 and the composite wall panel body 1, and prevent the outer metal shell 2 and the inner metal shell 3 from easily falling off.

[0033] When multiple composite wall panel bodies 1 need to be spliced ​​together during use, since one end of the composite wall panel body 1 is provided with a fixing groove 6 and the other end is provided with a limiting block 7, the limiting block 7 end of one composite wall panel body 1 is inserted into the fixing groove 6 of another composite wall panel body 1 and fixed with bolts, so that multiple composite wall panel bodies 1 can be quickly and stably assembled and used.

[0034] During the use of the composite wall panel body 1, the foam layer 8 is composed of high-density polyurethane foam, and its interior consists of independent sealed foam structure blocks 802. When in use, the independent sealed foam structure blocks 802 can block heat and noise, allowing the composite wall panel body 1 to achieve the purpose of heat insulation, sound insulation and noise reduction through the foam layer 8. In addition, the porous foam structure blocks 802 have good air permeability, preventing moisture and mold damage, which can extend the service life of the foam layer 8. This solves the problem that existing heat insulation cotton and sound insulation cotton are easily damaged after being exposed to moisture, resulting in poor heat insulation and noise reduction effect of metal composite wall panels.
