Abstract

본 발명은 물을 함유하는 발포제로 열가소성 중합체 발포제 구조물을 제조하는 방법에 관한 것이다. 본 방법은, 중합체를 용융시켜 중합체 용융물을 형성시키는 단계(a), 브롬화된 지방족 난연제를 중항제 용융물에 혼입시키는 단계(b), 제1발포제를 중합체 용융물에 혼입시키고 혼합하여 제1발포성 겔을 형성시키는 단계(c), 제1발포성 겔을 적합한 발포 온도로 냉각시키는 단계(d), 물을 포함하는 제2발포제를 냉각된 제1발포성 겔에 혼입시키고 혼합하여 제2발포성 겔을 형성시키는 단계(e), 제2발포성 겔을 적합한 발포 온도로 임의로 추가로 냉각시키는 단계(f) 및 제2발포성 겔을 압출 다이를 통해서 압출시켜 발포제 구조물을 형성시키는 단계(g)와 같은 일련의 단계들을 포함한다. 발포성 겔을 냉각시킨 후, 본 방법에서 수발포제를 하류 혼입하는 것은 공정에서의 부식 문제를 감소시키거나 최소화한다. 또한, 발포제 구조물을 제조하는 장치가 기술되어 있다.
