The present invention relates to an environmentally-friendly lightweight base material for an automotive interior. The base material improves humidity resistance and strength of a natural fiber reinforced layer by adding water-curable isocyanate or epoxy for reinforcing performances of the base material for an automotive interior and thus redeeming degradation of properties caused by moisture penetration into the natural fiber, wherein the automotive interior has a sandwich structure comprising a natural fiber which is weak to a high temperature and high humidity environment. Further, the base material is continuously manufactured by using thermal lamination on a core layer of a thermoplastic foaming sheet. The base material manufactured by the present invention is environmentally-friendly, and is used in various industrial fields including not only an automotive interior, but also a railroad, an aircraft, and a building interior by having excellent moisture resistance and strength while reducing weight thereof.

    본 발명은 자동차용 내장재용 친환경 경량기재에 관한 것으로서, 고온다습한 환경에 취약한 천연섬유를 포함하는 샌드위치 구조의 자동차 내장재용 기재의 성능 보완을 위해 수분경화형 이소시아네이트 또는 에폭시를 첨가하여, 천연섬유의 수분침투에 의한 물성저하를 보완하여 천연섬유 보강층의 내습성과 강도를 개선하고, 열가소성 발포시트 심재층에 열라미네이션을 이용하여 연속적으로 기재가 제조되는 것을 특징으로 한다. 본 발명에 의해 제조된 기재는 친환경 소재이며, 중량절감에 의한 경량화가 가능하면서 내습성과 강도가 우수하여 자동차 내장재 뿐만 아니라 철도, 항공기 및 건축용 내장재 같은 다양한 산업분야에 응용될 수 있다.
