초록

Isophorone diisocyanate(IPDI), poly(tetramethyleneglycol)(PTMG), dimethylol propionic acid(DMPA)를 출발물질로 하여 NCO terminated prepolymer가 합성되었다. 이 prepolymer의 NCO기를 silane으로 capping하기 위해 0~0.02 mole로 첨가량이 조절된 aminopropyl triethoxysilane(APS)이 첨가되었다. 제조된 용액의 평균 입경은 APS의 첨가량이 증가함에 따라 증가하였다. 또한 제조된 코팅 필름의 연필 경도 및 열적안정성은 순수한 수분산 폴리우레탄보다 우수하였다.

NCO terminated polyurethane prepolymers were synthesized from isophorone diisocyanate(IPDI), poly (tetramethyleneglycol)(PTMG) and dimethylol propionic acid(DMPA). Subsequently, aminosilane terminated prepolymers were prepared by capping the NCO groups of polyurethane prepolymers with different moles of aminopropyl triethoxysilane(0~0.02 mole) as a coupling agent. The average particle size of the silylated polyurethane solutions increased with increasing APS content. Also, the prepared coating films showed better thermal stability and pencil hardness than pure waterborne polyurethane.
