FLAME-RETARDANT HEAT-INSULATION STRUCTURE
To provide a flame-retardant heat-insulation structure which has high airtightness due to good adhesion to a building member, and is also excellent in flame retardancy.SOLUTION: A flame-retardant heat-insulation structure 10 is formed on a surface 11a of a building member 11, and includes a first layer 12 in contact with the surface 11a of the building member and a second layer 13 provided on the first layer 12, in which the first layer 12 and the second layer 13 are each formed of a foamable urethane resin composition containing at least a polyol compound, a polyisocyanate compound, a foaming agent and a catalyst, a degree of nuration of the first layer 12 is less than 1.0, and a degree of nuration of the second layer 13 is 1.0 or more.SELECTED DRAWING: Figure 1
【課題】建築部材に対する接着性が良好であることにより気密性が高く、かつ難燃性にも優れる難燃性断熱構造体を提供する。【解決手段】建築部材１１の表面１１ａに形成される構造体１０であって、建築部材表面１１ａに接する第１の層１２と、第１の層１２上に設けられた第２の層１３とを備え、第１の層１２及び第２の層１３が、それぞれポリオール化合物、ポリイソシアネート化合物、発泡剤、触媒を少なくとも含有する発泡性ウレタン樹脂組成物により形成され、第１の層１２のヌレート化度が１．０未満であり、第２の層１３のヌレート化度が１．０以上である、難燃性断熱構造体１０。【選択図】図１
