Abstract

본 발명은 폐섬유를 이용한 내, 외장재 및 그 제조방법에 관한 것으로, 중량비로써 타면된 폐섬유류 50－80%중에 열경화수지 15－30%, 분쇄된 폐PVC 또는 분쇄된 폐타이어를 단독 또는 혼합한 5－20%, 불연제, 방염제, 안료 등 부재료가 1% 미만 혼재된 내, 외장재로 이루어지고, 이에 대한 제조방법은 상기한 폐섬유를 타면하면서 상기한 원료를 분사되게 송풍시켜 폐섬유에 혼재되게 하고, 이어서 150－300℃ 및 150－250ton 압력에서 1차 핫프레싱(Hot Pressing)하고, 150－300℃ 및 1,000－2,000ton 압력하에서 2차 핫프레싱하고, 40－70℃에서 300－700ton 압력으로 콜드프레싱(Cold Pressing)함을 특징으로 하는 기술로 이루어진다.
