Abstract
To increase peel strength, low temperature properties and flowability of pressure sensitive adhesives(PSA) used in a heat shrinkable sheet, these properties were evaluated by changing each components in type and content. In this study, Isobutylene-co-Isoprene Rubber (IIR) which has good wetherability was selected as a base polymer. Instead of rosin ester, petroleum resin was selected as a tackifier because of superior peel strength. By decreasing petroleum resin contents, flowability of PSA was decreased. High molecular weight of polybutene was better than low molecular weight for the peel strength of PSA. Large particle size of carbon black showed better properties than small one in peel strength and brittleness temperature. By adding calcium carbonate, the cost of compound was able to be reduced. But it must be used with carbon black.
열 수축 쉬-트용 점착제의 접착성, 내한성 및 유동성을 향상시키기 위해 점착제를 구성하는 각 성분들의 종류 및 함량에 따른 물성을 평가하였다. 본 연구에서는 베이스 폴리머로서 내후성이 우수한 부틸고무를 선정하여 실험을 진행하였다. 점착부여제는 석유계 수지가 로진보다 우수한 접착력을 나타내었으며, 함량이 감소함에 따라 유동성이 저하됨을 알 수 있었다. 폴리부텐은 저 분자량보다 고 분자량의 물성이 우수하였다. 카본블랙의 경우 입자경이 클수록 물성 향상에 유리하였다. 탄산칼슘을 중량제로서 혼입할 경우 카본블랙과 함께 혼합시키는 경우가 바람직하였다.
