Abstract

본 발명은 자동차나 건축물 등에 사용되며 고밀도 수지층과 저밀도 수지층이 접합되어 흡음 및 차음기능을 하는 흡차음재시트에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sound absorbing and insulating material sheet for use in automobiles, buildings, and the like, wherein a high density resin layer and a low density resin layer are bonded to each other to provide sound absorption and sound insulation functions.

본 발명의 특징에 따르면, 흡차음용으로 사용되며 상대적으로 고밀도인 고밀도 수지층(110)과 상대적으로 저밀도인 저밀도 수지층(120)을 접합시켜서 된 시트(100)에 있어서, 상기 고밀도 수지층(110)과 상기 저밀도 수지층(120)을 동일한 발포 PU수지로 밀도를 달리하여 적층성형한 것을 특징으로 하는 흡차음재시트가 제공된다.According to a feature of the present invention, the high density resin layer 110 in the sheet 100, which is used for sound absorbing and insulating, by bonding a relatively high density high density resin layer 110 and a relatively low density low density resin layer 120, ) And the low-density resin layer 120 is provided with a sound absorbing and insulating material sheet, characterized in that the laminated molding by varying the density of the same foamed PU resin.
