A fireproof aluminum composite panel is a composite panel with an inorganic core layer and aluminum on both sides, and the decorative surface of the product is coated with a coating or a thin mold.
The fireproof aluminum composite panel is a novel type of fire-resistant material for high-end wall decoration. It is a new type of metal-plastic composite material created by hot pressing polymer bonding film (or hot melt adhesive) onto aluminum plates and a special flame-retardant-modified polyethylene plastic core material. It is regarded as a promising new high-end decorative material for modern curtain wall decoration due to its elegant appearance, beautiful appearance, fireproof and environmental protection, and simple construction. Currently, three types of "fireproof" aluminum composite panels are available on the market:
This type of fireproof aluminum composite panel has excellent flame retardancy and can pass the national mandatory standard GB8624-1997 "Combustion performance classification method of building materials" with consistency, and its combustion performance is not lower than that of B1 grade fireproof aluminum composite panel. The special material used in the core is an environmentally friendly, halogen-free flame-retardant polyethylene. The oxygen index is typically greater than 30% after using patented technology and a high-efficiency plasticizing and mixing process.
In the event of a fire, its flame-retardant core material burns slowly and produces no thick black smoke or toxic gases; it emits a small amount of smoke with no irritating odor, melt dripping, or environmental damage. This will give firefighters enough time to escape and prevent them from suffocating or dying as a result of inhaling a large amount of toxic gases. The core cross-section and peeling surface are generally white in appearance due to a high concentration of activated inorganic composite flame retardant.
The core material is a type of flame retardant that is made by adding a halogen-containing polymer or a halogen flame retardant to waste polyethylene recycled material (recycled plastic) and then combining it with a toxic hydrazine compound using a simple physical mixing method. The oxygen index in plastics is typically less than 27%.
In the event of a fire, pyrolysis, and combustion easily generate a large amount of toxic carbon monoxide and highly corrosive hydrogen halide flue gas, which is accompanied by a strong pungent odor and severe melt dripping. The B1 level inspection of the National Mandatory Standard GB8624-1997 "Classification Method of Combustion Performance of Building Materials" cannot consistently pass the combustion performance of the aluminum-plastic panel prepared by the same.
Because of the secondary pollution it causes in the environment, it is incompatible with the environmental protection requirements of today's building materials and is prohibited from use both at home and abroad. In developed countries such as Europe and the United States, there are many restrictions on the content of toxic substances such as heavy metals and polybrominated diphenyl ethers in plastic products, so such materials do not meet export standards. The peeling surface and core material are both dark gray or dark grayish-white in color.
It refers to the use of titanium dioxide to color the polyethylene regrind white, the use of a large amount of calcium carbonate filler, and the fact that the ordinary aluminum-plastic panel masquerading as a fire-resistant aluminum composite panel has almost no fire-retardant function. The peeling surface and core material cross-section are white or dark grayish-white.
The misunderstanding of fire-resistant aluminum-plastic composite panels is primarily reflected in the ambiguity of the national standard GB8624-97 "Building Materials Combustion Performance Grading Method," as well as "flame retardant of plastics" and the burning of "building composite materials."
An aluminum-plastic panel meets the GB8624-97 standard B1 grade or A-grade fireproof aluminum composite panel as a type of building composite decoration material composed of metal and plastic. Under the current conditions, the correct approach is to choose products from professional manufacturers with a good brand reputation or to send them to a national authoritative testing center for testing and grading.
1. A fireproof aluminum composite panel has excellent fire-retardant and flame-retardant properties and can pass the national mandatory standard GB8624 "Classification Method for Combustion Performance of Building Materials" with a combustion performance no lower than B1.
2. The fireproof aluminum composite panel has excellent peel strength, and good mechanical performance, and satisfies the international requirements of GB/T17748 "aluminum composite panel".
3. The fireproof aluminum composite panel core material process is highly adaptable and does not significantly alter the extrusion processing conditions of ordinary aluminum composite panels, allowing it to meet the technical requirements of various aluminum composite panel manufacturing processes at home and abroad.
4. The core material of the fireproof aluminum composite panel has excellent thermal aging resistance and can withstand high and low temperatures (-40 ° C - +80 ° C) cycled 20 times without change.
5. The flame retardant contained in the core material of the fireproof aluminum composite panel has good stability, does not migrate and precipitate, has good weather resistance, overcomes the defect that the general halogen flame retardant is not resistant to ultraviolet light, and is very suitable for interior and exterior architectural decoration.
6. The product's fireproof aluminum composite panel core material is white or light grayish-white and can be customized in a variety of colors.
7. The core material of a fireproof aluminum composite panel is an environmentally friendly flame-retardant cleaning material. It is halogen-free and smokeless. It is very difficult to burn. The amount of smoke produced when burning is negligible. There will be no corrosive gas or black smoke, and it is completely safe. It complies with the national green environmental protection requirements for building materials.
Airports, stations, subways, stadiums, shopping malls, office buildings, high-end cultural and entertainment centers, and other public places are the most common places to find it.
