본 발명의 경질 폴리우레탄폼용 폴리올 조성물은, 적어도 폴리올 화합물, 발포제 및 상용화제를 함유하고, 폴리이소시아네이트 화합물을 포함하는 이소시아네이트 성분과 혼합하여 발포, 경화시켜서 경질 폴리우레탄폼을 형성하는 경질 폴리우레탄폼용 폴리올 조성물이며, 상기 발포제가, 1-클로로-3, 3, 3-트리플루오로프로펜을 함유하고, 상기 상용화제가, 에틸디글리콜아세테이트를 함유한다. 본 발명의 경질 폴리우레탄폼용 폴리올 조성물에 의하면, 발포제로서 1-클로로-3, 3, 3-트리플루오로프로펜을 사용한 경우에도 분리 억제 등의 원액 보존 안정성이 좋고, 또한 경질 폴리우레탄폼의 물성 저하를 억제할 수 있는 경질 폴리우레탄폼용 폴리올 조성물을 제공할 수 있다. This polyol composition for rigid polyurethane foam is used to form a rigid polyurethane foam by mixing at least a polyol compound and an isocyanate component that contains a foaming agent and a compatibilizing agent and includes a polyisocyanate compound, foaming the mixture, and hardening the foam, wherein the foaming agent contains 1-chloro-3,3,3-trifluoropropene, and the compatibilizing agent contains ethyl diglycol acetate. With this polyol composition for rigid polyurethane foam, it is possible to provide a polyol composition for rigid polyurethane foam having excellent stock solution storage stability, such as suppression of separation, even when 1-chloro-3,3,3-trifluoropropene is used as a foaming agent, it being possible to minimize a decline in the properties of the rigid polyurethane foam.
