초록

본 연구에서는 폐 알루미늄을 이용하여 제조한 환경친화형인 발포 알루미늄 기능성 판넬의 특성을 조사하였고, 증점 공정, 교반 혼합 공정, 발포 공정, 냉각 공정을 거쳐 첨색 공정에 의한 제품 품질의 고급화를 추구하였다. 시험은 크게 세 가지로 구분하여 음향투과 손실 시험, 흡음율 측정 시험, 그리고 발포작업조건 및 스크랩 혼합시험을 시행하였다. 그 결과 폐 알루미늄을 이용해 만든 기능성 판넬은 초경량성이며 방음과 차음, 유해전자파 차폐에 탁월하고 약 2.2 kcal/mh℃ 정도로 낮은 열전도율 및 뛰어난 단열효과를 보이는 것으로 나타났다.

In this work, the properties of environmentally friendly functional panel made from waste aluminum were investigated. Product quality enhancement was pursued through an improved viscosity process, a mixing process by agitating, a foaming process, a cooling process, and a color addition process. An acoustic transmission attenuation test, a sound adsorption rate measurement test, and a foaming condition and scrap mixing test were implemented. As a result, the functional panel made from waste aluminum was ultra lightweight and had excellent properties such as soundproof, sound interception, and shielding harmful electromagnetic waves. Also, the functional panel showed low thermal conductivity (about 2.2 kcal/mh) and excellent heat-insulating property.

Keywords:environmental friendly functional panel;foamed aluminum
