Abstract

In this study, adhesion promoters with acrylate and carboxylic acid moiety were synthesized from malenized polybutadiene and 2-hydroxyethyl acrylate for producing adhesive film with low water absorption and high adhesion. The surface properties, adhesion strength, mechanical properties and water absorption of adhesive films were characterized according to the amount of acrylate and carboxylic acid in the synthesized adhesion promoters. As the carboxylic acid in the adhesion promoters increased, the adhesion strength showed a tendency to increase and the mechanical properties also improved compared to the commercial adhesion promoter. The compatibility of adhesion promoters improved remarkably due to the presence of polybutadiene (hydrophobic nature), maleic anhydride (hydrophilic nature) and carboxylic acid (hydrophilic nature).

본 연구에서는 상용성이 개선된 접착 증진제를 개발하기 위해 malenized polybutadiene과 2-hydroxyethyl acrylate(HEA)의 반응을 통해 다양한 함량의 아크릴레이트 반응기와 carboxylic acid가 도입된 접착 증진제(PBCA)를 합성하였다. 합성된 접착 증진제는 maleic anhydride의 개환 반응을 통해 도입된 아크릴레이트 반응기와 carboxylic acid의 함량, 그리고 접착 증진제의 첨가량을 달리하여 접착 필름을 제조하고 제조된 접착 필름의 표면 특성, 접착력 등의 기계적 특성과 흡습 특성 등의 변화를 확인하였다. 접착 증진제의 분자 내에 도입된 carboxylic acid의 함량이 증가할수록 접착 필름의 접착력은 증가하는 경향을 보였으며, 기존의 상용화된 접착 증진제와 비교하여 기계적 물성 또한 개선됨을 확인하였다. 특히, 분자 내에 소수성의 폴리부타디엔 주쇄와 친수성의 maleic anhydride 및 carboxylic acid가 동시에 존재함으로 인해 다양한 친수성 및 소수성 재료와의 상용성이 대폭 개선되었음을 확인하였다.
