Polyurethane adhesive has been investigated by many researchers for long time. However, relatively little systematic work has been reproted in detail, on the effect of numberous of the polyol in the properties of polyurethane. This work describes the properties of polyurethane adhesive. This work describes the properties of polyurethane adhesive in relation to the variation of polyol type and contents. Polyurethane adhesive were prepared from the polycarproractone, polycarbonate diol(PCD), polyester diol, polytetramethylene glycol(PTMG), polypropylene glycol(PPG), Toluene diisocyanate(TDI). FT-IR, thermogravimetric analysis(TGA), unversal testing machine(UTM) were utilized to characterize the physical and mechanical properties of polyurethane adhesive according to polyol type and contents. 감사의 글 : 본 연구는 2014년도 글로벌전문기술개발사업(수분전이 특성에 의해 자율적 통기조절 기능이 우수한 신발용 내피원단 개발)으로 수행되었음. |
