Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polyurethane resin composition excellent in high-temperature/high-humidity durability and flame retardancy and also excellent in workability.SOLUTION: The polyurethane resin composition contains: a polyurethane resin obtained by reacting an isocyanate group-containing compound with a hydroxyl group-containing compound; an inorganic filler; and a petroleum-based hydrocarbon. The isocyanate group-containing compound contains an isocyanurate-modified product of a polyisocyanate compound. The content of the inorganic filler is 50-85 mass% based on 100 mass% of the polyurethane resin composition.SELECTED DRAWING: None 【課題】高温高湿耐久性及び難燃性に優れ、且つ、作業性に優れたポリウレタン樹脂組成物を提供することを目的とする。【解決手段】イソシアネート基含有化合物と水酸基含有化合物とが反応してなるポリウレタン樹脂、無機充填剤及び石油系炭化水素を含有するポリウレタン樹脂組成物であって、前記イソシアネート基含有化合物は、ポリイソシアネート化合物のイソシアヌレート変性体を含み、前記無機充填剤の含有量は、ポリウレタン樹脂組成物１００質量％に対して、５０〜８５質量％である、ことを特徴とするポリウレタン樹脂組成物。【選択図】なし
