Description

Technical Field

[0001] This utility model relates to the field of aluminum ceiling panel technology, specifically to an aluminum ceiling panel with fireproof and fire-fighting functions. Background Technology

[0002] Aluminum ceiling panels are made from aluminum alloy sheets through processes such as cutting, corner trimming, and molding. Various coatings are applied to the surface of aluminum ceiling panels to create a variety of products. There are two main types of aluminum ceiling panels: integrated aluminum ceiling panels for home decoration and integrated aluminum ceiling panels for engineering projects. Initially, integrated aluminum ceiling panels for home decoration were mainly available in two series: roller coating and frosted finish.

[0003] When in use, aluminum ceiling panels do not have fire-resistant and fire-fighting functions. Consequently, when exposed to open flames, aluminum ceiling panels do not have the ability to actively suppress the fire, which can lead to secondary fires. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an aluminum ceiling panel with fire prevention and fire protection functions, which has the advantages of fire prevention and fire protection for aluminum ceiling panels and solves the problem that aluminum ceiling panels do not have fire prevention and fire protection functions.

[0005] This utility model discloses an aluminum ceiling panel with fire-resistant and fire-fighting functions, comprising an aluminum ceiling panel body. The surface of the aluminum ceiling panel body is provided with a folded edge, and a fireproof sealing strip is provided at the connection between the inner cavity of the folded edge and the aluminum ceiling panel body. The aluminum ceiling panel body includes an aluminum substrate, and a honeycomb-shaped cavity is formed on the back of the aluminum substrate. The inner cavity of the honeycomb-shaped cavity is filled with a solid aerosol fire extinguishing agent, and a low-melting-point polymer film is provided on the surface of the honeycomb-shaped cavity. A ceramic fiber heat insulation layer is provided on the back of the aluminum substrate, and the connection between the ceramic fiber heat insulation layer and the back of the aluminum substrate is fixedly connected by a high-temperature resistant adhesive. When the aluminum ceiling panel body is exposed to an open flame, the low-melting-point polymer film ruptures when the temperature reaches a certain level, and the solid aerosol fire extinguishing agent in the honeycomb-shaped cavity is automatically released to inhibit combustion. Through the combination of the high-temperature resistant adhesive and the ceramic fiber heat insulation layer, heat can be blocked from spreading to the back side, preventing objects on the back from spontaneously combusting due to high temperature. The folded edge and fireproof sealing strip can prevent flames from escaping from the panel seams and causing secondary fires.

[0006] The present invention relates to an aluminum ceiling panel with fire-resistant and fire-fighting functions, wherein the thickness of the aluminum substrate is 0.7mm, and the surface of the aluminum substrate is sprayed with an expanding coating of ammonium phosphate, and the thickness of the expanding coating of ammonium phosphate is 0.3mm. The present invention uses an expanding coating containing ammonium phosphate to carbonize and expand when the aluminum substrate is exposed to an open flame, thus delaying the spread of the fire.

[0007] The present invention relates to an aluminum ceiling panel with fireproof and fire-fighting functions, wherein the thickness of the ceramic fiber heat insulation layer is 5mm, and the material of the high-temperature resistant adhesive is silicone heat-resistant adhesive.

[0008] The present invention relates to an aluminum ceiling panel with fireproof and fire-fighting functions, wherein the honeycomb cavity has a pore size of 3mm, the solid aerosol fire extinguishing agent is a K-type aerosol fire extinguishing agent, and the low-melting-point polymer film is a polyethylene or paraffin composite film.

[0009] The present invention relates to an aluminum ceiling panel with fireproof and fire-fighting functions, wherein the height of the folded edge is 10mm and the fireproof sealing strip is made of expanded graphite.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. When the aluminum ceiling panel is exposed to an open flame, the low-melting-point polymer film ruptures when the temperature reaches 150°C. The solid aerosol extinguishing agent in the honeycomb cavity is automatically released to suppress combustion. Through the combination of high-temperature resistant adhesive and ceramic fiber insulation layer, heat can be blocked from spreading to the back side, preventing objects on the back from spontaneously combusting due to high temperature. Through edge folding and fireproof sealing strips, flames can be prevented from escaping from the panel seams and causing secondary fires.

[0012] 2. This utility model uses an expanding coating containing ammonium phosphate, which can carbonize and expand when the aluminum substrate is exposed to an open flame, thus delaying the spread of the fire. Attached Figure Description
