Problems solved by technology

Many existing fire doors are sandwiched with cement core materials in the steel plate to improve the fireproof, heat insulation and sound insulation effects of the door, but the door body is too heavy, which is inconvenient in the process of transportation and construction installation. The hinges used to support the fire doors are also easily bent and deformed by the weight of the doors, thus affecting the normal use of the fire doors
And the heavy fire door is not easy to open and close in an emergency

Embodiment 1

[0013] A fireproof door made of foamed aluminum, including a door frame 1 and a door leaf 2, the door leaf 2 is made of foamed aluminum material, and the foamed aluminum is made by the following method: a. heating recycled aluminum to 670°C to melt it; b. Add 5% (weight) silicon carbide particles to the aluminum liquid, the particle diameter is 15 μm, stir evenly c, pass nitrogen gas into the aluminum liquid, and stir the aluminum liquid at the same time, the speed of the mixer is 600r / min, d, for the aluminum liquid The temperature is lowered to solidify the molten aluminum to make aluminum foam boards, which are then cut into required sizes.

Embodiment 2

[0015] A fireproof door made of foamed aluminum, including a door frame 1 and a door leaf 2, the door leaf 2 is made of foamed aluminum material, and the foamed aluminum is made by the following method: a. heating recycled aluminum to 675°C to melt it; b. Add 3% (weight) silicon carbide particles into the aluminum liquid, stir evenly c, pass nitrogen into the aluminum liquid, and stir the aluminum liquid at the same time, the speed of the mixer is 800r / min, d, cool down the aluminum liquid, so that the aluminum The liquid is solidified to make a foamed aluminum board, and the foamed aluminum board is cut into the required size.

Abstract

The invention belongs to the field of building materials and particularly relates to a fire door made of foamed aluminum. The fire door made of the foamed aluminum comprises a door frame and a door leaf. The door leaf is made of foamed aluminum materials. A manufacturing method of the foamed aluminum comprises the following steps that a, aluminum is heated to 650 DEG C-680 DEG C so that the aluminum is melted; b, silicon carbon particles with the weight percentage being 2%-5% are added into the liquid aluminum and are stirred to be even; c, nitrogen gas is led into the liquid aluminum, and the liquid aluminum is stirred at the same time, wherein the rotating speed of a stirrer is 600 r / min-1,000 r / min; d, the liquid aluminum is cooled, so that the liquid aluminum is solidified, and a foamed aluminum plate is manufactured. The fire door is manufactured by utilizing the advantages of being light in weight, good in sound isolation, high in strength and resistant to fire of the foamed aluminum, so the defects that an existing fire door is clumsy and expensive are overcome; besides, the fire door is convenient to install and use, and the cost of the fire door is also lowered.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a fireproof door made of foamed aluminum. Background technique [0002] The accredited laboratory designated by the Ministry of Economic Affairs, according to the new version of the national standard for fire doors GB_12955-2008 implemented on January 1, 2009, has passed the test of the fire resistance test method for fire doors, and has obtained the verification registration certificate and authorized logo issued by the Standard Inspection Bureau of the Ministry of Economic Affairs , called fire doors. There are actually many types of fire doors. For example, according to materials, there are wooden fire doors, steel fire doors, etc.; according to function: there are access control fire doors, indoor fire doors, etc.; according to technology: there are electronic fire doors, etc. Many existing fire doors are sandwiched with cement core materials in the steel plate ...
