In the fields of building, shipbuilding, and energy transportation, there is an increasing demand for excellent thermal energy saving and thermal insulation, and excellent thermal and thermal insulation.

In general, the heat insulating material is classified into organic heat insulating material, inorganic heat insulating material, and composite heat insulating material, and widely used heat insulating materials include styrofoam, polyurethane foam, and glass wool (glass fiber).

Styrofoam is excellent in light weight and heat insulation, but has a problem in that it is vulnerable to fire and is incombustible and emits deadly toxic gas in case of fire. When the fillers used in the sandwich panel are made of foamed synthetic resin, All organizational structures are very vulnerable to fire. Accordingly, a structure made of a conventional sandwich panel has a problem in that a fire spreads very quickly and a great damage occurs in a short time, and in particular, a large amount of toxic gas is generated while burning, causing serious casualties.

Here, the manufacturing method of a sandwich panel manufactured by embedding a conventionally produced styropol (EPS; expanded polystyrene) in the domestic is pre-foamed polystyrene beads (Polystyrene beads) at a predetermined expansion ratio and then dried in a silo (Silo) After aging, it is heated and cooled until it is softened in a molding machine to make a molded product, and after being cured for one week, the non-composed EPS panel made by cutting to the standard with a hot wire is used as a steel sheet (zinc sheet, galvanium sheet, fluorine coated sheet, aluminum Sandwich panel is made by cutting to size after bonding using adhesive between steel sheet, color steel sheet, etc.The non-combustible EPS sandwich panel has high insulation effect, excellent economy, sound insulation, light weight, mechanical strength and chemical resistance. It has been widely used because of its harmlessness to human body. The large fire that caused by toxic exposure to this deadly problem of gas generation and flammability of these panels flame retardant is a very urgent situation.

In addition, the flame-retardant panels thus formed may exhibit a certain degree of flame retardant performance, but the bonding strength of the flame retardant material itself is deteriorated, which is a decisive problem in that it does not continuously maintain its shape when molded to a predetermined size and is easily broken even in small presses. This is being pointed out.
