Abstract

The present invention is an ultralight made by attaching a flame retardant phenol foamed resin core material prepared with a phenol resin and an inorganic additive and a non-flammable sheet made of a fiber, wood, paper alone or a combination of two or more types coated with a non-flammable foam on both sides of the core material. A fireproof and fireproof panel with a complex structure with excellent sound absorption, sound insulation and heat insulation and excellent fire and flame resistance and low toxic gas generation in a fire was manufactured.

Description

Fire-proof Panel {A Fire-proof Panel}

The present invention relates to a fire door and a fire protection panel as a structure of a building such as an apartment, a building, a factory, etc., and has a light weight, excellent sound absorption, sound insulation, and heat insulation, and excellent fire resistance, flame retardancy, and low toxic gas generation. It relates to a fire protection panel.

In general, a fire-resistant panel is made by inserting a gypsum board or structural combination with inorganic fibers such as glass fiber, rock wool and mineral wool. However, such a panel generates a lot of problems in the price of the core material or harmful to the human body and thermal insulation properties, especially the heavy weight is not good workability. In another form, when the urethane, polyimide, and polystyrene foamed resin including inorganic additives such as flame retardants are used as the sole core, the fire door and the fire panel are manufactured with low ignition point due to the low ignition effect due to fire and toxic gas There is a fatal drawback that causes many lives.

Therefore, the flame retardant properties according to the present invention are excellent in flame retardancy, low generation of toxic gas and excellent insulation effect, and made of flame retardant phenolic foamed resin as a core material, non-combustible made of fiber, wood, paper alone or a combination of two or more coated with a nonflammable foam liquid. The sheet was attached to both sides of the core material to block the propagation of heat and heat transfer in the event of a fire. It is also an object of the present invention to manufacture a fireproof and fireproof panel excellent in light weight, sound absorption and sound insulation, and heat insulation by phenolic foam resin, which is a core material.

＊ Explanation of symbols on main parts of drawing

1, 5; Surface finishes 2, 4; Nonflammable sheet

3; Flame Retardant Phenolic Foam

The configuration of the present invention by attaching a non-combustible sheet made of a combination of a flame retardant phenol foam resin having a thickness of 35mm as a core material and a fiber, wood, paper alone or two or more types coated with a non-flammable foam liquid having a thickness of 2.0mm on both sides of the core material The composite structure was prepared and surface-treated with a galvanized steel sheet having a thickness of 0.6 mm to prepare a fire resistant panel.

The fire-resistant fireproof panel manufactured as described above was radiated with a high temperature flame at 1,100 ° C. As a result, there was almost no toxic gas generation, flame propagation, and resin dripping at a high temperature. Was found to be 120 ° C or lower.

The fireproof / fireproof panel manufactured by the present invention is lighter than the existing fire doors and fireproof panels, and has excellent sound absorption, sound insulation, and heat insulation. It relates to a fire prevention panel.
