Abstract

제안된 열 용융 접착제는 a)1종 이상의 폴리이소시아네이트, 특히 톨루엔 디이소시아네이트 및/또는 MDI, b)총 열 용융 접착제 기준으로 10중량% 이상의 농도인 1종 이상의 폴리알킬렌 글리콜, 득히 폴리프로필렌 글리콜, c)1종 이상의 폴리에스테르 글리콜, 특히 상이한 유리 전이 온도를 갖는 2종 이상의 폴리에스테르 글리콜로 구성된 A)1종 이상의 폴리우레탄 프리폴리머; 및 d)수지, 특히 탄화 수소 수지 및 e)안정화제, 특히 톨루엔 술포닐 이소시아네이트 같은 B)임의의 첨가제를 함유한다.
접착제의 용융 점도는 130℃에서 10∼300Pa. S 범위내임이 바람직하다. PU 프리폴리머는 DSC 다이아그램에서 단지 1개의 Tg를 갖는다. 이 접착제는 높은 초기 강도 및 최종 강도 외에 크리프(creep)에 대하여 높은 저항성을 갖는다. 따라서, 이것은 주로 신발 산업, 특히 생산 라인에 포함되어, 증기 사용의 예비 가교 결합단계를 포함하지 않으며 건조 채널을 갖지 않는 피복 기기에서의 사용에 적합하다. 이 접착제는 단일 공정에서 제조됨이 바람직하다.
