Description

Technical Field

[0001] This application relates to the technical field of sandwich panels, and specifically relates to a composite sandwich color steel plate. Background Art

[0002] A sandwich panel is composed of two layers of formed metal panels (such as color steel plates, stainless steel plates, or aluminum plates, etc.) and an insulating core material directly in the middle of the two panels, which is convenient for installation, lightweight, and efficient. The existing insulating core material of sandwich panels generally uses rock wool core material, but the fire resistance time of the rock wool core material sandwich panel is about 1 hour, and the short fire resistance time often cannot meet the requirements. Utility Model Content

[0003] This application provides a composite sandwich color steel plate to solve the problems of poor fire resistance performance and short fire resistance time of the existing sandwich panels, and adopts the following technical solutions:

[0004] The composite sandwich color steel plate includes a first panel and a second panel, and a sandwich layer provided between the first panel and the second panel. An insulating layer is provided between the sandwich layer and the first panel and the second panel. A fireproof adhesive is provided on the insulating layer to connect the sandwich layer with the first panel and the second panel into one body. A fireproof layer is also provided on the surfaces of the first panel and the panel.

[0005] Preferably, a frame is further provided between the first panel and the second panel, and the frame is located outside the sandwich layer.

[0006] Further preferably, the first panel and the second panel are provided with a flange at the outer edge, and the flange fits the frame.

[0007] Preferably, the insulating layer is aerogel felt or honeycomb aerogel elastomer, which can effectively reduce the transfer of heat.

[0008] Preferably, the fireproof layer is aerogel fireproof coating, water-based fireproof coating or fluorocarbon fireproof coating, which can block the transfer of heat and improve the fire resistance performance.

[0009] The beneficial effects of this application are:

[0010] An insulating layer is provided between the first panel and the second panel and the sandwich layer. The insulating layer and the fireproof adhesive can effectively reduce the transfer of heat. Fireproof layers are provided on the outer sides of the first panel and the second panel, and the fireproof layers can block part of the heat transfer. This structure can improve the overall fire resistance time and fire resistance to meet the requirements of fire resistance time, and has good overall heat insulation performance.

[0014] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings of the present application. Obviously, the described embodiments of the present application are only partial embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present application.

[0015] Refer to Figure 1 , and further illustrate the present application. The composite sandwich color steel plate includes a first panel 1 and a second panel 2, and a sandwich layer 3 provided between the first panel 1 and the second panel 2. Among them, the first panel 1 and the second panel 2 can be color steel plates, stainless steel plates or aluminum plates, etc.; the sandwich layer 3 can be a fireproof core material such as rock wool or aluminum honeycomb; a heat insulation layer 4 is provided between the sandwich layer 3 and the first panel 1 and the second panel 2, and the heat insulation layer 4 connects the sandwich layer 3 with the first panel 1 and the second panel 2 into an integrated body. A refractory adhesive is provided on the heat insulation layer 4 to bond the sandwich layer to the first panel 1 and the second panel 2 respectively. Among them, the refractory adhesive can form a dense, flame-retardant and heat-insulating film layer at high temperatures. A fireproof layer 7 is also provided on the surface of the first panel 1, thereby improving the overall heat insulation and heat preservation performance and improving the fireproof time limit.

[0016] The heat insulation layer 4 is aerogel felt or honeycomb aerogel elastomer, which not only has strong heat insulation performance, but also is environmentally friendly and durable; the honeycomb aerogel elastomer is specifically described in the patent document with the patent number 202210585329.3; the fireproof layer 7 can be aerogel fireproof paint, water-based fireproof paint or fluorocarbon fireproof paint, which has high fireproof performance and excellent heat insulation performance. Among them, the refractory adhesive, the heat insulation layer 4 and the fireproof layer 7 cooperate with each other, can block most of the heat and have strong heat preservation performance, and can greatly improve the fireproof duration of the sandwich panel.

[0017] A frame 5 is also provided between the first panel 1 and the second panel 2. The frame 5 is located outside the sandwich layer 3. The frame 5 cooperates with the first panel 1 and the second panel 2 to be able to wrap the sandwich layer 3 and the heat insulation layer 4 inside, avoiding the exposure of the sandwich layer 3, improving the sealing performance and the overall strength. Edge stops 6 are provided at the outer edges of the first panel 1 and the second panel 2. The edge stops 6 are attached to the frame 5, thereby restricting the movement of the frame 5 and preventing the frame 5 from detaching from the first panel 1 and the second panel 2, improving the overall tightness.
