Description
Technical Field
The utility model relates to a prevent fire door technical field, in particular to fire door is prevented to magnesium oxide inner core three-layer combined type.
Background
At present, a fire door is a door that can satisfy fire resistance, integrity and heat insulation requirements for a certain period of time, and is a fire partition that is installed in a fire partition, an evacuation stairwell, a vertical shaft, etc. and has a certain fire resistance. For example: the fire extinguishing device is attached to equipment rooms (steel bottle rooms, foam stations and the like) for fixing the fire extinguishing device in high-rise civil buildings, and the first-level fireproof door is adopted as a partition wall door of a ventilation and air conditioning machine room and the like; a class A fireproof door is adopted for a door on a partition wall of a basement room where people often stay or combustible materials are more; because of the limitation of conditions, a boiler for burning oil and gas, a power transformer for burning oil and soaking combustible oil, a high-voltage capacitor filled with combustible oil, a switch and the like must be arranged in a high-rise building, and a door on a partition wall of a special room is a class-A fireproof door. And the special-requirement fire-proof individual door is designed, such as the individual door of a fire-fighting monitoring command center, a file data room, a valuable goods warehouse and the like, and a class A or class B fire-proof door is usually selected. The individual door of high-rise high-grade residential building is usually a fire-proof anti-theft door. The fire door is an important component in fire-fighting equipment and is an important part in social fire prevention, and a door closer of the fire door or a door closing device (except for a special part, such as a pipeline well door and the like) for automatically closing a door leaf of a normally open fire door can be arranged on the fire door.
The traditional fireproof door has at least the following disadvantages in the using process: prevent that fire door easily appears deformation such as warpage, bending under the higher condition of temperature, lead to preventing the appearance gap between fire door main part and the fire prevention door frame, flame or dense cigarette are easily scurried out from the gap, and then have reduced safety protection performance, and the effect of fire prevention is poor, easily the accident appears.
Therefore, the magnesium oxide inner core three-layer composite fireproof door is provided.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a fire door is prevented to magnesium oxide inner core three-layer combined type has better fire behavior.
In order to achieve the above purpose, the technical solution of the present invention is as follows:
the utility model provides a fire door is prevented to magnesium oxide inner core three-layer combined type, includes prevents the fire door body, prevent that the fire door body includes framework, fire prevention outer surface layer, fire prevention intermediate level and fire prevention inlayer all set up in the framework, the fire prevention intermediate level comprises pottery silicon rubber jacket layer and the fire-retardant material of packing between pottery silicon rubber jacket layer, the fire prevention inlayer comprises the frame that the surface has the cavity and the magnesium oxide expanded material of packing in the frame cavity, framework and frame all adopt metal material to make.
Specifically, the fireproof outer surface layer is made of a non-combustible inorganic board material, and a fireproof paint layer is coated on the outer side of the fireproof outer surface layer.
Specifically, the thickness of the fireproof paint layer is 1-2 mm.
Specifically, the flame retardant material is made of one of rock wool, expanded perlite or glass fiber cotton.
