Preparation and Properties of Polyurethane Foamed Leather Having Good Permeability to Moisture Vapor by Dry Process

폴리에스터디올과 톨루엔 디이소시아네이트로부터 얻은 우레탄 예비폴리머와 촉매 및 계면활성제를 사용하여, 건식가공법으로 투습성이 우수한 폴리우레탄 발포피혁을 제조하였다. 폴리우레탄 발포피혁의 발포비는 이소시아네이트(NCO) 함량이 증가할수록 또한 계면활성제농도가 감소할수록 증가하였으며 인장강도와 파단신율은 계면활성제의 함량에 따라서는 증가하였으나 NCO 함량에 따라서는 감소하였다. 발포피혁의 발포밀도는 촉진제와 수분의 함량이 증가할수록 감소하였으며 발포밀도가 증가할수록 인장강도와 파단신율은 증가하였다. 투습도는 NCO 함량의 증가에 따라 증가하였다.
