A fire door having a fireproof insulation and fireproofing insulation material and its manufacturing method of fireproof insulation

摘要

The present invention relates to a fireproof insulation material, a manufacturing method of the fireproof insulation, and a fire door provided with the fireproof insulation material which are able to completely prevent spread of fire. According to the present invention, the fireproof insulation material is characterized in that a fire-resistant insulation material is inserted into a melt insulation material in an insert method to be integrated with the melt insulation material. In the manufacturing method of the fireproof insulation material according to the present invention, the fire-resistant insulation material inserted into the center of an inner portion of a compression chamber from the rear side in an insert type when compressing the melt insulation material in a general Styrofoam compressing method, thereby manufacturing the melt insulation material integrally to be melt and compressed on an outer surface of the fire-resistant insulation material. The fire door according to the present invention is inserted into the fireproof insulation material as a core and is fixed by adhesion.
