Abstract

In this study, TAPEH (t-amyl peroxy 2-ethyl hexanoate) was selected for the reaction initiator which is a core factor for developing acrylic polyol binder. Tone M100 (caprolactone acrylate), 4HBA (4-hydroxy butyl acrylate), and 2HEMA (2-hydroxy ethyl methacrylate) were used for hydroxy-monomers. To check the applicability of raw materials mentioned above into the binders of 2 components acrylic polyurethane paint and reduce the VOC, the reactivity and film performance by different kinds of aliphatic polyisocyanate hardeners which are already generalized were reviewed. As the Tin-based catalyst has been regulated, the comparison test of reactivity and performance between the conventional catalyst and non-toxic metal catalyst recommended as the alternative was conducted as well. As a result, we were able to obtain the basic data which are necessary for applying 2 components high solid polyurethane paint and also reached a conclusion that it can be applied for developing new paints in terms of high performance, workability and environmental care.

본 연구에서는 2액형 아크릴 우레탄 도료에 있어서 바인더로 사용되는 하이솔리드 아크릴 폴리올 수지를 개발함에 있어서 핵심요소인 반응 개시제로 TAPEH (t-amyl peroxy 2-ethyl hexanoate)를 선택하였다. 그리고 하이드록시 모노머는 Tone M100 (caprolactone acrylate), 4HBA (4-hydroxy butyl acrylate), 2HEMA (2-hydroxy ethyl methacrylate)를 사용하였다. 앞의 물질을 2액형 아크릴 우레탄 도료용으로 응용함에 있어서 적용성과 VOC 저감을 위하여, 알리파틱 폴리이소시아네이트 경화제 종류에 따른 반응성과 도막물성을 검토하였다. 또한 최근 주석계 촉매의 사용 억제에 따라 저독성 금속촉매와의 반응성 및 물성도 비교 시험하였다. 이상의 결과로부터 2액형 하이솔리드 폴리우레탄 수지 도료의 응용에 필요한 기초자료 확보로 도막물성과 작업성 개량 및 친환경 도료개발에 효과적으로 응용 할 수 있는 것을 검토하였다.
