초록

Isophorone diisocyanate(IPDI), polycarbonate diol(PCD), dimethylol propionic acid(DMPA)를 출발물질로 하여 NCO terminated prepolymer가 합성되었다. 이 prepolymer의 NCO기를 아크릴 단량체로 capping하기 위해 다양한 아크릴 단량체인 2-hydroxyethyl methacrylate(HEMA), 2-hydroxyethyl acrylate(HEA), pentaerythritol triacrylate(PETA)가 첨가되었다. 제조된 용액의 평균 입경은 아크릴 단량체가 첨가되면서 증가하였다. 또한 제조된 코팅 막의 연필경도 및 내마모성은 순수한 수분산 폴리우레탄보다 우수하였으며, 아크릴 단량체 중에서 PETA가 가장 우수한 물성을 보였다.

NCO terminated polyurethane prepolymers were synthesized from isophorone diisocyanate(IPDI), polycarbonate diol(PCD) and dimethylol propionic acid(DMPA). Subsequently, acrylic terminated polyurethanes were prepared by capping the NCO groups of polyurethane prepolymers with different types of acrylate monomers, such as 2-hydroxyethyl methacrylate(HEMA), 2-hydroxyethyl acrylate(HEA) and pentaerythritol triacrylate(PETA). The average particle sizes of the acrylic terminated polyurethane solutions were increased by capping acrylate monomers. Also, the prepared coating films showed better abrasion resistance and pencil hardness than those of pure waterborne polyurethanes. The coating film with PETA exhibited the best abrasion resistance and pencil hardness of coating films prepared with three acrylate monomers.
