Abstract
Two-component polyurethane flame retardant coatings were prepared by blending chlorine-containing modified polyesters (MCAOs) and polyisocyanate. MCAOs were synthesized by polycondensation of monochloroacetic acrid, a flame retardant aliphatic carboxylic acid, with 1,4-butanediol, trimethylolpropane, and adipic acid. The content of monochloroacetic acid was varied 10, 20, and 30 wt% for the reaction. These new flame retardant coatings showed various properties comparable to other non-flame retardant coatings. They were superior to flamable coatings from the experimental results showing rapid and 9 to 11 hours of pot-life. Coatings with 30 wt% monochloroacetic acid was not flamable by the vertical flame-retardancy test.

난연성 지방족 카르복시산인 모노클로로아세트산의 함량을 10, 20, 30 wt%로 변화시키면서 1, 4-부탄디올, 트리메틸올프로판 및 아디프산과 축중합을 하여 염소함유 변성폴리에스테르(MCAO류)를 합성한 후에, MCAO류와 폴리이소시아네이트를 블렌드하여 2성분계 폴리우레탄 난연도료를 제조하였다. 제조된 난연도료의 제반 물성을 측정해 본 결과 비난연성 도료보다 물성이 떨어지지 않았고, 오히려 건조시간 측정에서 속건성을 나타내었으며, 가사시간이 9∼11시간으로 나타나 바람직한 속건성 난연도료임이 밝혀졌다. 또한 난면도료의 난연성 시험결과 수직법시 모노클로로아세트산 3wt %에서 불꽃에 타지 않아서 양호한 난연도료임이 입증되었다.
