Abstract

결정 융점이 130∼200℃인 고융점의 공중합 폴리에틸렌 테레프탈레이트 수지와 결정융점이 50∼120℃ 저융점의 공중합 폴리부틸렌 테레프탈레이트 수지의 이층으로 된 이층 필름형 폴리에스테르 접착제 및 제조방법으로서, 본 발명에 의해 제공되는 이층 필름형 폴리에스테르 접착제는 고융점 수지와 저융점 수지를 모두 포함하므로써, 특히 특성이 상이한 피착제들 사이의 접착에 있어서 저융점 수지 접착제 또는 고융점 수지 접착제를 단독 사용하는 것보다 우수한 효과를 나타낸다.As a two-layer film-type polyester adhesive and a manufacturing method of two layers of a high melting point copolymerized polyethylene terephthalate resin having a crystal melting point of 130 to 200 ° C. and a copolymerization polybutylene terephthalate resin having a crystal melting point of 50 to 120 ° C. The two-layer film type polyester adhesive provided by the invention includes both a high melting point resin and a low melting point resin, so that a low melting point resin adhesive or a high melting point resin adhesive is used alone, particularly in the adhesion between adherents having different properties. It shows a better effect.
