摘要
The present invention relates to a fireproof door having an expansion type fire-resistant sheet with improved insulation properties and fire resistance. A honeycomb-shaped reinforcement material is formed inside a fire-roof frame composed of inner and outer panels to reinforce the insulation properties and durability of the fireproof door, and a non-flammable fire-resistant sheet foamed and expanded by reacting between the reinforcement member and the panel at a temperature equal to or higher than the predetermined temperature is coupled to prevent thermal deformation of the fireproof door in case of a fire, rapidly block the fire, improve the thermal insulation properties and soundproofing properties, and improve durability. Moreover, the purpose of the present invention is to provide a fireproof door having an expansion type fire-resistant sheet with improved insulation properties and fire resistance to improve productivity by simplifying the manufacturing process.;COPYRIGHT KIPO 2016
