Abstract

New antibacterial Polyurethane foams for car seat with Urushiol extracted from a natural lacquer were prepared. Influences of antibacterial agent's concentration on the reactivity with isocyanate and the mechanical properties of foams were investigated. It was observed that the urethane formation reaction was delayed a little when the amount of Urushiol was increased. However, the foams made using Urushiol showed similar property to the neat polyurethane foam. In terms of antibacterial property, the foams prepared with Urushiol showed better performance than the neat polyurethane foam.

천연 옻 나무에서 추출되는 항균물질 우르시올을 폴리우레탄 발포체 성형 시스템에 도입하여 항균 폴리우레탄 발포체를 제조하였다. 항균물질 우르시올 첨가량을 증가시키는 경우 발포체 성형 반응성이 약간 저하되는 것이 관찰되었으나 기계적 물성 측면에서는 항균물질 미처리 발포체와 비교하여 큰 물성저하는 관찰되지 않았다. 반면 항균성 측면에서는 항균물질 미처리 발포체에 비하여 초기 균수 대비 균수의 성장성이 감소되는 것을 확인할 수 있었다.
