Abstract
Two-component polyurethane(PU) flame-retardant coatings were prepared by blending tribromo modified polyesters(TBAOs) and isocyanate. TBAOs were synthesized by condensation polymerization of tribromoacetic acid, a flame-retardant component, with 1,4-butanediol, adipic acid, and trimethylolpropane. The content of tribromoacetic acid was varied by 10, 20, and 30 wt% for the reaction. Various physical properties of these new flame-retardant coatings were comparable to nonflame-retardant coatings. Coatings with 20 wt% tribromoacetic acid did not burn during the vertical burning test.

난연성분인 트리브로모아세트산의 함량을 10, 20, 30 wt%로 변화시키면서 1,4-부탄디올, 아디프산 및 트리메틸올프로판과 축합중합을 하여 트리브로모 변성폴리에스테르 (TBAO)를 합성한 후에, TBAO류와 이소시아네이트를 블렌드하여 2성분계 폴리우레탄 (PU) 난연도료를 제조하였다. 제조된 난연도료의 도막물성을 측정한 결과, 결코 비난연도료보다 불성이 저하되지는 않았다. 또한 난연도료의 난연성 시험결과, 수직법에서 트리브로모아세트산 20 wt%에서 불꽃에 타지 않아서 양호한 난연도료임을 알 수 있다.
