Performance Improvement of Unsaturated Polyester/Alumina Composites for Organic Building Material : (I) Surface Treatment of Filler

초록

유기건축 복합재료의 대표적인 수지인 orthophthalic게 불포화 폴리에스테르를 매트릭스 수지로 사용하여 불포화 폴리에스테르/알루미나 복합재료를 제조하였다. 충전재인 알루미나의 표면을 실란 카플링제의 농도 변화에 따라 처리하여 충전재/매트릭스 수지의 계면 개질화를 시도하였으며, FT-IR DRIFT 방법에 의해 알루미나 표면을 분석하였다. 실란 카플링제로 알루미나 표면을 처리시 미처리 알루미나의 경우에 비해 불포화 폴리에스테르/알루미나 복합재료의 기계적 물성이 증가하였으며, 실란 카플링제의 종류에 관계없이 기계적 물성의 최대치를 나타내는 최적 실란농도가 존재하였다. 또한 실란 카플링제의 농도와 복합재료의 기계적 물성에 대한 상관관계도 고찰하였다.

In order to apply for organic building material, unsaturated polyester/alumina composites have been fabricated using orthophthalic unsaturated polyester matrix resin. Alumina, as a filler, was surface treated with variation of silane concentration and the modified alumina surface was analyzed by FT-IR-DRIFT method. Compared with untreated alumina/unsaturated polyester composite, surface treated alumina/unsaturated polyester composites have retained the increased mechanical properties and optimum silane Concentration, which shows the maximum mechanical properties of unsaturated polyester/alumina composite. exists irrespective of the type of silane coupling agent. In addition, the relationship between silane concentration and the mechanical properties of unsaturated polyester/alumina composites was also discussed.
