URETHANE RESIN COMPOSITION, FIRE-RESISTANT REINFORCEMENT METHOD FOR HOUSING MATERIAL, AND FIRE-RESISTANT REINFORCEMENT STRUCTURE FOR HOUSING MATERIAL
PROBLEM TO BE SOLVED: To easily construct a fire-resistant reinforcement structure in an opening in a housing material.SOLUTION: A urethane resin composition comprises a polyisocyanate compound, a polyol compound, a catalyst, a blowing agent, a foam stabilizer, and an additive, where at least one of the polyisocyanate compound and the polyol compound contains an aromatic ring, at least one of the polyisocyanate compound and the polyol compound contains two or more methylene groups bonded, at least one of the polyisocyanate compound and the polyol compound satisfies the following relationship: 0≤(molecular weight of polyisocyanate compound)/(number of polymerizable functional groups of polyisocyanate compound)≤1000, and/or 0≤(molecular weight of polyol compound)/(number of polymerizable functional groups of polyol compound)≤1000, and the additive contains at least one selected from the group consisting of phosphate esters, fire retardants containing phosphates, fire retardants containing halogens, and metal hydroxides.SELECTED DRAWING: Figure 1
【課題】建材の開口部に、耐火補強構造を簡単に施工すること。【解決手段】ウレタン樹脂組成物は、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うちの少なくとも一方が芳香環を有し、ポリイソシアネート化合物およびポリオール化合物のうちの少なくとも一方にメチレン基が２つ以上連結し、ポリイソシアネート化合物およびポリオール化合物のうちの少なくとも一方が、下記の関係を満たし：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、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ことを特徴とする。【選択図】図１
