Abstract
종래의 전분충전형 플라스틱 관련 기술에서는 매트릭스 수지와 전분과의 물리적인 결합력만을 증가시키므로써 전분이 충전됨에 따른 물성 감소의 문제점이 있었는 바, 본 발명에서는 반응압출(Reactive Extrusion)법을 이용하여 매트릭스 수지와 전분을 유기산 촉매하에서 결합제를 사용하여 화학결합으로 연결시켜 물성감소의 문제점을 해결하였음은 물론 제조공정 단순화를 통해 제조원가를 현저히 줄일 수 있었다. 즉, 본 발명은 매트릭스수지 100중량부, 생분해성 충전제 5∼400중량부, 결합제 0.01-10중량부, 라디칼개시제 0.01∼1.0중량부, 루이스산 촉매 0.01∼5중량부, 자동산화제 0.01∼10중량부 및 가소제 0.01∼10중량부로 이루어진 것을 특징으로 하는 전분이 화학 결합된 생분해성 폴리에틸렌 조성물 및 그의 제조방법을 제공하는데 목적이 있다. 본 발명에 따라 제조된 폴리에틸렌 조성물의 생분해성 평가는 토양 매립실험을 병용해 실시하였는데 생분해도는 전분 함량이 10중량% 이상인 경우 뛰어난 것으로 나타났다.
