Abstract

Prepared polyurethane resin for vegetable leather coating on surface was synthesized with glycerol which had different mole ratio. Mechanical properties of the synthesized polyurethane resin were measured by the SEM, FT-IR, UTM. Growing concerns in the evnironment-friendly polymer resin, we have synthesized low late obtained solvent water dispersion resin to be coating on vegetable leather. The increase of aliphatic trihydric alcohol glycerol mole %, abrasion resistance and tensile strength had highly stronger in intensity and longer durability. On the contrary, demonstrated reduce properties of elongation and flexibility. In the result of toluene solvent resistance, there was no effect of increased or decreased by the ratio of glycerol mole %.

Vegetable leather 표면 코팅에 사용된 폴리우레탄 수지는 glycerol의 함유를 mole % 비로 달리하면서 합성하였다. 합성된 폴리우레탄 수지의 기계적 특성은 SEM, FT-IR, UTM 등을 이용하여 측정하였다. 친환경적인 고분자 수지의 관심이 고조됨에 따라 용제의 사용을 최소화한 vegetable leather 코팅에 사용되는 수분산 수지를 합성하였다. 지방족 3가 알콜인 glycerol의 mole % 비가 증가함에 따라 내마모도, 인장강도가 증가함을 알 수 있었다. 반대로 연신율, 내굴곡 물성은 감소함을 알 수 있었다. Toluene을 이용한 내용제성 물성측정 결과에는 glycerol의 mole % 증가에 따른 물성 증감 효과는 없었다.
