Abstract

In this study we synthesis Hybrid resin(WPC) by milk casein and waterborne polyurethane(WPU). Then we experiment how casein effect to Hybrid resins in Full-Grain leather coatings. According to measured data for solvent resistance, WPU resin and Hybrid resins had good property. As test of tensile strength, WPU had most low strength(2.130 $kg_f/mm^2$) and WPC-3(WPU 91: casein resin 9) had most high strength(2.191 $kg_f/mm^2$). Also we knew that most good property of abrasion is WPC-3(50.090 mg.loss). In elongation case, WPU had most good result(637 %) in this experiment.

본 연구에서는 밀크 카제인과 WPU를 이용한 하이브리드 수지를 합성하였다. 합성한 하이브리드 수지를 피혁(Full-Grain) 표면에 코팅을 하여 카제인이 하이브리드수지에 어떤 영향을 주는지에 대해 분석 하였다. 내용제성 테스트 데이터에 의하면 WPU 와 하이브리드 수지 양쪽 모두 높은 물성치를 나타내었다. 인장 강도 측정치에서는 WPU 단독 결과(2.130 $kg_f/mm^2$)가 가장 낮은 수치를 나타내었으며, WPC-3(WPU 91: casein resin 9)의 경우가 가장 높은 인장력(2.191 $kg_f/mm^2$)을 나타내었다. 또한 내마모도 측정에서는 WPC-3(50.090 mg.loss)가 좋은 물성값을 나타내었다. 연실률의 경우 WPU(637 %) 단독 코팅물의 분석값이 가장 높은 637%로 알 수 있었다.
