초록

본 연구에서는 폴리비닐알콜(PVA)와 폴리프로필렌글리콜(PPG)기반의 창상피복용 수분산 폴리우레탄수지를 합성하였으며, 시료의 물리적 특성을 필름 시료와 피혁(Full-Grain) 표면에 코팅을 하여 물리적 특성 변화를 연구하였다. 인장강도의 경우 PVA가장 적게 반응된 PUD-PA1 2.00 kgf/㎟ 으로 가장 높은 저항성을 보였으며. 마찬가지로 연실율은 PVA가장 적게 반응된 PUD-PA1가 554%로 높게 측정되었다. 내마모성 측정 결과 PVA 반응이 증가함에 따라 표면의 강도나 낮게 36.77 mg.loss로 감소됨을 알수 있었다.

In this study, polyvinyl alcohol (PVA) and polypropylene glycol (PPG)-based polyurethane dispersion resin for wound coating was synthesized. And the physical properties of the sample were coated on the surface of the film sample and the leather (Full-Grain) to study the physical properties change. In the case of tensile strength, PUD-PA1, which reacted with the least amount of PVA, showed the highest resistance at 2.00 kgf/㎟. Likewise, the rate of elongation was measured as high as 554% for PUD-PA1, which reacted with the least amount of PVA. The abrasion resistance measurement result showed that as the PVA response increased, the strength of the surface decreased to 36.77 mg.loss.
