Abstract
본 발명의 일 실시예에 따르면, 천연 나노복합광물을 포함한 폴리우레탄 VOCs저감용 첨가제 제조방법은 (a) 어트리션밀에 점토질 일라이트광물 및 제올라이트를 투입하는 단계; (b) 어트리션밀에 분쇄용 볼을 투입하고, 분산제를 추가로 투입하는 단계; (c) 상기 추가 투입 이후 분산 및 분쇄를 하여 점토질 일라이트광물 및 제올라이트의 분말을 수득하는 단계; 및 (d) 상기 수득한 분말을 볼밀에서 스테인리스볼을 이용하여 볼밀링하여 24시간 내지 48시간 동안 분쇄하는 단계를 포함한다. 따라서, 우레탄 발포체를 형성하는 스프레이 과정 중에 발생하는 VOCs(volatile organic compounds)를 효율적으로 제거할 수 있는 첨가제를 제조할 수 있다.
