Claims (1)

복수층의 성형방음재를 성형하는 금형표면에 진공탈기용홈 및/또는 진공탈기구멍을 형성하여 이루어진 하금형에, 시이트형상물 및 열경화성 합성수지를 함유하는 로프트 부직포를 순차로 적층하고, 이어서 이 진공탈기용홈 및/또는 진공탈기구멍으로부터 진공흡인하면서 동시에 가열가압성형하는 것을 특징으로 하는 성형방음재의 제조방법.A loft nonwoven fabric containing a sheet-like material and a thermosetting synthetic resin is sequentially laminated in a lower die formed by forming a vacuum degassing groove and / or a vacuum degassing hole in a mold surface for molding a plurality of molded soundproofing materials. A method for producing a molded soundproofing material, characterized by performing vacuum pressurization while vacuum suction from a groove and / or a vacuum degassing hole. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
