The present invention relates to a sound absorbing and insulating material for automotive engine encapsulation and, specifically, to a sound absorbing and insulating material for automotive engine encapsulation that is formed in multiple layers including a polymer resin layer, a polyurethane foam layer, a silica aerogel layer, and an aluminum sheet layer, is not bulky to improve adhesion, can be applied to an engine where a high temperature generates, is closely applied to the engine, more efficiently reduces heat energy and noise emitted to the outside of the engine, and exhibits improved insulating and sound absorbing effects.

    자동차 엔진 인캡슐레이션용 흡음성 단열재에 관한 것으로서, 상세하게는 고분자 수지층, 폴리우레탄폼층, 실리카 에어로겔층 및 알루미늄 시트층을 포함하여 다층으로 형성되면서도 그 부피가 크지 않아 밀착성이 향상되고 고온이 발생되는 엔진에도 적용할 수 있어, 엔진에 밀착 적용되어 엔진 외부로 방출되는 열에너지와 소음을 보다 효율적으로 감소시켜 향상된 단열 및 흡음 효과를 나타내는 자동차 엔진 인캡슐레이션용 흡음성 단열재에 관한 것이다.
