초록

3,5,5-trimethylhexanoic acid(THA)와 트리메틸올프로판을 에스테르화시켜 중간생성물을 얻은 후, 중간생성물 속의 알키드 폴리올 성분인 THA의 함량을 10, 20, 30wt.%로 변화시키면서 1,4-부탄디올, 트리메틸올프로판 및 아디프산과 축중합하여 알키드 변성폴리에스테르를 각각 합성하였다. 위에서 합성된 알키드 변성폴리에스테르에 폴리이소시아네트쪽 성분인 Desmodur L-75와 블렌드하여 2성분계 폴리우레탄 도료를 제조하였다. 제조된 도료의 도막처리후의 제반 물성시험을 해 본 결과 3,5,5-trimethylhexanoic acid의 함량증가에 따라 8⁺점의 높은 연화도, 2∼3시간의 짧은 건조시간 및 18∼23시간의 긴 가사시간을 나타내어 알키드기의 장점이 일부 나타남을 확인하였다.

Alkyd modified polyester was synthesized by the polycondensation of 1,4-butanediol, trimethylolpropane, adipic acid, and the intermediate obtained by the esterification of 3,5,5-trimethylhexanoic acid(THA) and trimethylolpropane, where the contents of THA as a component of alkyd polyol in the intermediate were changed according to 10, 20, and 30wt%, respectively. Two-component polyurethane coatings were prepared by blending the synthesized alkyd modified polyester with Desmodur L-75 as a component of polyisocyanate. Various tests for coating properties with the prepared coatings show that high fineness of grind of 8 point, short drying time of 2∼3 hours, and long pot-life of 18∼23 hours were observed with the content of 3,5,5-trimethylhexanoic acid.
