The present invention relates to a manufacturing method of a sound-absorbing material by recycling a waste seat of an automobile and to a sound absorbing material manufactured thereby. The present invention exhibits the following effects. That is, according to the present invention, it is possible to prevent environmental pollution by recycling the waste seat of the automobile, which is currently entirely discarded, and to have excellent sound absorption by preventing a pore part of a pulverized product obtained by crushing the waste seat of the automobile from being clogged.
본 발명은 자동차 폐시트를 재활용하여 흡음재를 제조하는 방법 및 그에 의해 제조된 흡음재에 관한 것이다. 본 발명은 다음과 같은 효과를 발휘한다. 즉, 본 발명에 따르면, 현재 전량 폐기되는 자동차 폐시트를 재활용함으로써 환경오염을 방지할 수 있을 뿐만 아니라, 자동차 폐시트를 파쇄하여 얻은 분쇄물의 기공부분이 막히지 않도록 함으로써 우수한 흡음성을 갖도록 하는 장점이 있다.
