Description

A method of manufacturing a ceiling and an outermost wall-type flame-retardant metal panel for fire prevention}

The present invention relates to a method of manufacturing a flame retardant metal panel that can be used in various applications such as ceilings and outermost walls for fire prevention, while a plurality of them are continuously connected to each other.

In general, building panels, called 'sandwich panels', are most widely used in temporary buildings, such as prefabricated houses, warehouses, or factories.

The sandwich panel is provided with a heat insulating material between the two outer plate and the inner plate, it is in close contact with each other by adhesive or compression. The sandwich panel as described above is cut to a suitable size and then used as a wall or a roof of a building.

Insulation materials used in such sandwich panels include styroform or polyurethane, and glass wool or mineral wool made of PIR (polysocyanurate) and glass fiber reinforced with flame retardancy on the polyurethane. Etc. are used.

However, all of the insulation material made of urethane, glass wool or mineral wool has the advantage of being flame retardant or non-flammable, but has a disadvantage that the unit price is too expensive. In addition, the insulating material made of glass wool itself contains a carcinogen. As a result, when the panel is manufactured or dismantled, carcinogens contained in the glass fiber may penetrate into the human body and cause cancer.

For such reasons, styrofoam, which is inexpensive, has excellent thermal insulation, and is easy to manufacture and dismantle, is widely used as a heat insulating material for sandwich panels.

However, when a fire occurs in a building installed by assembling the building panel using the styrofoam as a heat insulating material, the styrofoam has a low flash point and easily burns, so it is easily burned and burned. In addition, since the insulation made of styrofoam is filled in the entire building panel constituting the prefabricated building, there is a problem that the fire spreads to the whole building in an instant.
