Abstract

폴리우레탄 발포체 및 이의 제조 방법이 개시된다. 포리올을 용제로하여 디올 및 디이소시아네이트를 반응시켜 우레탄디올폴리올 혼합체를 제조한다. 상기 우레탄디올폴리올 혼합체를 사용하여 주제인 디이소시아네이트 프리폴리머를 제조하고, 상기 우레탄디올폴리올 혼합체를 사용하여 경화제인 폴리올 조성물을 제조한다. 상기 경화제 100중량%에 대해 상기 주제 70~130중량%를 혼합하여 우레탄 디올 폴리올 혼합체를 제조한다. 폴리우레탄 발포체는 비중이 매우 낮으면서 탈형시간이 2~5분으로 단축되고 표면특성 및 물성이 향상되므로 신발창용으로 효과적으로 사용할 수 있다.Polyurethane foams and processes for their preparation are disclosed. The diol and the diisocyanate are reacted with the polyol as a solvent to prepare a urethane diol polyol mixture. Using the urethane diol polyol mixture, a subject diisocyanate prepolymer is prepared, and the urethane diol polyol mixture is used to prepare a polyol composition as a curing agent. 70% to 130% by weight of the subject is mixed with 100% by weight of the curing agent to prepare a urethane diol polyol mixture. The polyurethane foam can be effectively used for shoe windows because the specific gravity is very low, the demolding time is shortened to 2 to 5 minutes, and the surface characteristics and physical properties are improved.
