초록
Isophorone diisocyanate (IPDI), polycarbonate diol (PCD), dimethylol propionic acid (DMPA)를 출발물질로 하여 수분산 폴리우레탄(waterborne polyurethane dispersion, PUD)을 합성하였다. 이 PUD에 아크릴 단량체인 HEMA (2-hydroxyethyl methacrylate)와 MMA (methyl methacrylate)의 혼합물을 첨가하여 수분산 폴리우레탄-아크릴 혼성 용액을 제조하였다. 그 결과 제조된 혼성 용액의 평균 입도는 아크릴 단량체의 첨가량이 증가함에 따라 증가하였다. 또한 수분산 폴리우레탄-아크릴 혼성 용액으로부터 제조된 코팅 도막의 내마모성과 내화학성은 순수한 PUD 보다 크게 향상되었다.
Waterborne polyurethane dispersions (PUD) were synthesized from isophorone diisocyanate (IPDI), polycarbonate diol (PCD) and dimethylol propionic acid (DMPA) as starting materials. Subsequently, waterborne polyurethane-acrylic hybrid solutions were prepared by reacting the PUD with different amounts of the mixture of acrylate monomers, HEMA (2-hydroxyethyl methacrylate) and MMA (methyl methacrylate). As a result, the average particle size of waterborne polyurethane-acrylic hybrid solutions was increased with increasing the addition amounts of acrylate monomers. Also, the prepared coating films from waterborne polyurethane-acrylic hybrid solutions showed better abrasion resistance and chemical resistance than those of pure PUD.
