Abstract
본 발명은 생분해성 포장용 완충재의 제조방법에 관한 것으로 전분류 및 그의 글라이신 유도체에 물성 보강제, 가소제, 압출 윤활제 및 발포 조절제를 단독 또는 그 이상 혼합하여 압출기로 직접 발포시킨 제품으로 생분해될 뿐만 아니라 양호한 외관 및 기계적물성(강도 및 복원력)을 지니는 포장용 완충재를 제조하는 방법이다.
즉, 포장용 완충재의 강도 및 복원력을 개선하기 위하여 첫째, 가소제인 글라이신(glycine)을 화학적으로 결합시켜 전분 자체에 가소성을 부여한 변성전분을 타 전분류와 단독 또는 혼합하여 사용하는 방법, 둘째 전분류 및 그의 글라이신 유도체에 천연물질인 리그노설포네이트(lignosulfonate)를 소량 첨가하에 제조하는 방법. 셋째, 고분자성 가소제중 특히 폴리비닐알코올(polyvinylalcohol)을 첨가함에 있어 기존의 호모폴리머(homopolymer)를 사용하는 방법과는 달리 호모폴리머에 공중합체(copplumer)를 혼합하여 사용하는 방법을 특징으로 하는 생분해성 포장용 완충재를 제조하는 방법이다.
본 발명에 의한 포장용 완충재는 생분해될 뿐만 아니라 양호한 외관 및 기계적 물성(강도와 복원력)이 우수하고 전분류의 고른 분산성에 의한 발포로 조직이 치밀하므로 최근 문제가 되고 있는 플라스틱 폐기물을 환경 친화성 소재로 대체할 수 있는 유용한 방법이다.
