In order to solve the disadvantage of bulkiness in the prior art, a light and sound insulation Aluminum foam for fire doors solves the above problems.
A kind of fireproof door made of Aluminum foam for fire doors, including door frame and door leaf, and door leaf is made of Aluminum foam for fire doors material. The Aluminum foam for fire doors is made by the following method: A, heating the recycled aluminum to 650-680 degree , melting it, B, adding 2-5% (weight) silicon carbide particles into the aluminum liquid, stirring evenly C, adding nitrogen to the aluminum liquid, stirring the aluminum liquid at the same time. The speed of the mixer is 600-1000r/min, D, cooling the aluminum liquid, solidifying the molten aluminum, making the Aluminum foam for fire doors, and cutting the foam aluminum plate into the required size.
The Aluminum foam for fire doors can be cut according to the size of the required door.
The silicon carbide particles can be replaced by alumina or calcium carbonate.
The aluminum can be melted in the mold and directly made into the size of the required fire door.
The invention has the beneficial effect that the fire door is made by using the characteristics of light Aluminum foam for fire doors, good sound insulation, strong intensity and fire resistance, which solves the shortcomings of the existing fireproof door, which is more cumbersome and high in price, facilitates the installation and use of the fire door, and reduces the cost of the fire door.
