Abstract

Pressure sensitive adhesive (PSA) was prepared by semi-batch emulsion polymerization of acryl monomers in the presence of reactive and non-reactive carboxylated polyurethane resin (PUR). Effects of the PUR type, its content, and crosslinker feeding method on the adhesive properties of the PSA was investigated. In this experiment, the PSA prepared with the reactive PUR showed better adhesive property then the PSA with the non-reactive PUR. Especially, peel strength of the PSA, where acetoacetoxy ethyl methacrylate and 1,6-hexane diamine as crosslinkers were introduced, was dramatically enhanced in severe humidity condition due to the interfacial crosslinking.

카르복실화된 비반응성 및 반응성 폴리우레탄 레진을 이용, 아크릴 단량체의 반회분식 유화중합법을 통해 점착제를 제조하였다. 폴리우레탄 레진의 종류, 함량 그리고 가교제의 투입 방법에 제조된 점착제의 점착 성능에 대해 연구하였다. 본 실험에서 반응성 폴리우레탄 레진에 의해 제조된 점착제가 비반응성 폴리우레탄 레진에 의해 제조된 것에 비해 우수한 점착 성능을 나타내었다. 특히, acetoacetoxy ethyl methacrylate와 1,6 hexane diamine을 가교제로 도입하여 제조된 점착제는 혹독한 가습조건에 계면가교반응으로 인해 월등한 peel strength를 보여 주었다.
