URETHANE RESIN COMPOSITION, FIRE PROOF REINFORCEMENT METHOD OF HOUSING MATERIAL, AND FIRE PROOF REINFORCEMENT STRUCTURE OF HOUSING MATERIAL
To provide a fire proof reinforcement method of a housing material, and a fire proof reinforcement structure of a housing material capable of further sufficiently filling without protruding from the opening of the housing material.SOLUTION: A urethane resin composition 8 contains: polyisocyanate compound; polyol compound; catalyzer; a foaming agent; a foam control agent; and an additive agent. At least one of polyisocyanate compound and polyol compound contains aromatic ring; two or more methylene groups are linked; further, 0≤molecular weight of polyisocyanate compound)/(number of polymerizable functional groups in the polyisocyanate compound)≤1000; and/or 0≤(molecular weight of polyol compound)/(number of polymerizable functional groups in the polyol compound)≤1000; are satisfied. Also, the additive agent includes at least one selected from the group consisting of phosphoric esters, phosphate-containing flame retardants, halogen-containing flame retardants and metal hydroxide.SELECTED DRAWING: Figure 1
【課題】建材の開口部からはみ出さずにより確実に充填できる建材の耐火補強方法および建材の耐火補強構造を提供する。【解決手段】ウレタン樹脂組成物８は、ポリイソシアネート化合物、ポリオール化合物、触媒、発泡剤、整泡剤および添加剤を含み、ポリイソシアネート化合物およびポリオール化合物の少なくとも一方が芳香環を有し、メチレン基が２つ以上連結し、さらに、０≦（ポリイソシアネート化合物の分子量）／（ポリイソシアネート化合物中の重合可能な官能基の数）≦１０００、および／または、０≦（ポリオール化合物の分子量）／（ポリオール化合物中の重合可能な官能基の数）≦１０００、を満たす。また添加剤が、リン酸エステル、リン酸塩含有難燃剤、ハロゲン含有難燃剤および金属水酸化物からなる群より選ばれる少なくとも一つを含む。【選択図】図１
