Description

Technical Field

[0001] This utility model relates to the field of building wall panel technology, and more specifically, to an aerogel fireproof and heat-insulating composite wall panel. Background Technology

[0002] Aerogel is a solid material and one of the least dense solids in the world, with a density of only 3 kilograms per cubic meter. Since more than 99.8% of aerogel is air, it has a very good heat insulation effect. One inch of aerogel is equivalent to the heat insulation function of 20-30 mm of ordinary glass.

[0003] Building wall panels are commonly used building materials in construction. With the improvement of living standards, people have higher and higher requirements for the fire resistance and heat insulation of their residences. However, the fire resistance and heat insulation effects of existing building wall panels still need to be improved. Building wall panels are generally only fireproofed by concrete. When flames are in continuous contact with the building wall panels, they are easy to crack and damage the building wall panels. Existing building wall panels have poor heat insulation effect in summer and poor heat insulation effect in winter. Utility Model Content

The aerogel insulation coating on the side of the intermediate layer closer to the mortar layer includes an aerogel water-based anti-corrosion primer and an aerogel water-based waterproof topcoat. The aerogel insulation coating on the side of the intermediate layer away from the mortar layer includes an aerogel water-based high-temperature resistant primer and an aerogel water-based heat-reflective topcoat.

[0008] Furthermore, the aerogel insulation board has several semi-circular grooves with a radius of 4 ml on the layer near the mortar layer, and the grooves are filled with mortar.

[0009] Furthermore, the aerogel insulation layer includes a flexible fixing layer and aerogel fine powder uniformly distributed on the flexible fixing layer. The flexible fixing layer consists of three layers, which are interconnected by needle punching. The aerogel fine powder is uniformly distributed between the connecting surfaces of the different flexible fixing layers.

[0010] Furthermore, the flexible fixing layer is a flexible fiber felt or a flexible fiber blanket.

[0011] Furthermore, the aerogel insulation layer is coated with fire-retardant adhesive on the side of the light steel keel that is close to the light steel keel, and the fire-retardant adhesive bonds the aerogel insulation layer and the light steel keel together. The side of the aerogel insulation layer away from the light steel keel is coated with fire-retardant paint.

[0012] Furthermore, the aerogel flame-retardant layer is a foam-reinforced SiO2 aerogel layer, and the foam in the foam-reinforced SiO2 aerogel layer is melamine foam or PU foam.

[0020] The components include: 1. Mortar layer; 2. First insulation layer; 3. Light steel keel; 4. Aerogel insulation layer; 5. Aerogel flame retardant layer; 6. Decorative wall panel; 7. Sound-absorbing cotton; 8. Stitching connection steel wire. Detailed Implementation

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

[0022] See attached document Figure 1 As shown, an aerogel fireproof and heat-insulating composite wall panel includes a mortar layer 1 and a first insulation layer 2 bonded to the mortar layer 1. A light steel keel 3 is provided on the surface of the first insulation layer 2 away from the mortar layer 1. An aerogel insulation layer 4 is provided on the other side of the light steel keel 3. An aerogel flame-retardant layer 5 is provided on the other side of the aerogel insulation layer 4. A decorative wall panel 6 is provided on the other side of the aerogel flame-retardant layer 5. One end of a stitching connecting steel wire 8 is fixed to the mortar layer 1, and the other end is fixed to the decorative wall panel 6. The stitching connecting steel wire 8 is cross-fixed. The setting of the stitching connecting steel wire 8 makes the composite wall panel less prone to cracking and extends the service life of the composite wall panel.

[0023] The first insulation layer 2 is an aerogel insulation board, which includes an intermediate layer. Both surfaces of the intermediate layer are coated with aerogel insulation paint. The aerogel insulation paint on the side of the intermediate layer closest to the mortar layer 1 includes an aerogel water-based anti-corrosion primer and an aerogel water-based waterproof topcoat. The aerogel water-based anti-corrosion primer reduces the corrosion resistance of the intermediate layer surface, while the aerogel water-based waterproof topcoat improves the waterproof performance of the intermediate layer surface. The aerogel insulation paint on the side of the intermediate layer furthest from the mortar layer includes an aerogel water-based high-temperature resistant primer and an aerogel water-based heat-reflective topcoat. The aerogel water-based high-temperature resistant primer has good high-temperature resistance and can act as a flame retardant. The aerogel water-based heat-reflective topcoat effectively insulates the surface of the intermediate layer furthest from the mortar layer, further improving heat reflection efficiency and thus reducing the heat exchange efficiency between the outside and the interior of the building, thereby achieving the function of insulation.

[0024] The aerogel insulation board has several semi-circular grooves with a radius of 4 ml on the layer closest to the mortar layer. The grooves are filled with mortar, which improves the adhesion of the composite board.

[0025] The aerogel insulation layer 4 includes a flexible fixing layer and aerogel powder uniformly distributed on the flexible fixing layer. The flexible fixing layer consists of three layers interconnected by needle punching. The aerogel powder is uniformly distributed between the connecting surfaces of the different flexible fixing layers. The flexible fixing layer is a flexible fiber felt or flexible fiber blanket. The aerogel insulation layer 4 further blocks external heat from entering the room, making the room cooler in summer and improving the room's insulation performance in winter, while preventing heat from escaping from the room.

[0026] The aerogel insulation layer 4 is coated with fire-retardant adhesive on the side closest to the light steel keel. The fire-retardant adhesive makes the aerogel insulation layer 4 and the light steel keel 3 bond together. The side of the aerogel insulation layer 4 away from the light steel keel 3 is coated with fire-retardant paint. The two surfaces of the aerogel insulation layer 4 are coated with fire-retardant adhesive on one surface and fire-retardant paint on the other surface, which improves the fire resistance of the composite wall panel.

[0027] The aerogel flame-retardant layer 5 is a foam-reinforced SiO2 aerogel layer. The foam in the foam-reinforced SiO2 aerogel layer is melamine foam or PU foam, and the thickness of the foam in the foam-reinforced SiO2 aerogel layer is 0.5mm-15mm. The aerogel flame-retardant layer 5 is bonded to the aerogel heat insulation layer and the decorative wall panel respectively by fire-retardant adhesive.

[0028] like Figure 2 As shown, the surface of the light steel keel 3 is wrapped with a layer of sound-absorbing cotton 7, which improves the sound insulation function of the wall panel and reduces the impact of outside noise on the residents.

[0029] This utility model, installed on the outside of the wall with expansion bolts, not only achieves the effect of keeping the room warm in winter and cool in summer, but also improves the fire resistance of the wall and enhances the sound insulation of the wall panel, preventing outside noise from entering the room.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
