Abstract
이를 실현하기 위한 본 발명의 발포판재 제조방법은, 원재료인 원목 또는 목재칩을 분쇄하여 목분을 제조하는 단계; 상기 목분에 생분해성 수지를 투입한 후 고온 혼련하여 혼합물(Compounds)을 제조하는 단계; 상기 제조된 혼합물을 판상으로 성형하는 단계; 상기 성형된 판재를 발포 성형하는 단계; 및 상기 발포 성형된 판재를 냉각시키는 단계;를 포함하여 이루어진 것을 특징으로 한다.
이와 같은 본 발명에 의하면, 생분해성 수지 및 목분을 포함하여 제조함에 따라 우수한 물성을 부여할 수 있고, 발포 공정을 통해 제조함으로써 경량화는 물론 차음과 단열 성능을 향상시킬 수 있으며, 폐기물 처리 관련 비용을 줄일 수 있는 장점이 있다.
Description
도 2는 본 발명에 따른 발포판재 제조방법의 다른 실시예를 보여주는 흐름도이다.
