초록
압력감응성 아크릴 점착제의 물성은 관능성그룹을 가진 단량체의 가교를 통하여 쉽게 물성을조절할 수 있다. 본 연구에서는 두개의 다른 가교제, isocyanate 및 epoxy형 가교제에 따른 아크릴 점착제의가교특성과 물성을 연구하였다. 2-Ethylhexyl acrylate, acrylic acid (AA)와 2-hydroxyethyl methacrylate 를 주 단량체로 하여 이소시아네이트 또는 에폭시형 가교제로 가교한 점착제의 박리점착특성, 볼텍,유지력 및 수축성을 고찰하였다. 점착특성은 AA함량 증가와 더불어 증가하였고 가교점이 많고 ether 와 같은 유연한 결합을 생성하는 에폭시형 가교제에서 우수한 물성을 나타내었다.
Abstract
The physical properties of the acrylic pressure sensitive adhesives (PSAs) can be easily controlled by a proper functional monomer which has functional groups for crosslinking. This study was to investigate the effect of crosslinking agents, isocyanate and epoxy types, of acrylic PSAs on adhesive properties. 2-Ethylhexyl acrylate, acrylic acid (AA), and 2-hydroxy ethyl methacrylate as monomer were used. The obtained samples with different AA contents were partially crosslinked with epoxy- or isocyanate-typed agent. Peel strength, balltack, holding power test and contraction percentage of the obtained PSA were evaluated. Most properties of acrylic PSAs were increased with AA content and acrylic PSAs with epoxy-typed crosslinking agent (4 crosslinking sites) which produces flexible link (ether), showed better properties than those of isocyanate-typed one (3 crosslinking sites).
